Description
BACKGROUND
Technical Field

Certain embodiments disclosed in the disclosure relate to an antenna and an electronic device including the same.


Description of Related Art

An electronic device may transmit and/or receive a radio frequency (RF) signal representing a voice signal or data (e.g., a message, a picture, a video, a music file, or a game) by using an antenna.


The antenna may simultaneously transmit and receive signals belonging to different frequency bands. The electronic device may service a global communication band by using signals belonging to different frequency bands. For example, the electronic device may perform communication (e.g., a global positioning system (GPS), Legacy, and Wifi1) that uses signals belonging to a low frequency band (LB), and/or communication (e.g., Wifi2) that uses signals belonging to a high frequency band (HB).


As a next-generation (e.g., a fifth generation, 5G) communication is introduced, the electronic device may support new frequency bands, such as millimeter wave (mmWave) and/or sub6 (e.g., n78 and n79). The electronic device may include an antenna for supporting new frequency bands.


The placement of the antenna presents a number of issues. Generally speaking, the front surface has very little room because of the display, and front facing cameras. It also may not be easy to place an antenna in the interior of the electronic device due to the amount of space.


To allow the electronic device to support new frequency bands, when the number of radiators included in the electronic device may increase but a space of the electronic device decrease, a radiation performance of the antenna may decrease.


Certain embodiments disclosed in the disclosure provide an electronic device that may increase radiation performance while including antennas of various bands.

The communication module 190 may support establishing a direct (e.g., wired) communication channel or a wireless communication channel between the electronic device 101 and the external electronic device (e.g., the electronic device 102, the electronic device 104, or the server 108) and performing communication via the established communication channel. The communication module 190 may include one or more communication processors that are operable independently from the processor 120 (e.g., the application processor (AP)) and supports a direct (e.g., wired) communication or a wireless communication. According to an embodiment, the communication module 190 may include a wireless communication module 192 (e.g., a cellular communication module, a short-range wireless communication module, or a global navigation satellite system (GNSS) communication module) or a wired communication module 194 (e.g., a local area network (LAN) communication module or a power line communication (PLC) module). A corresponding one of these communication modules may communicate with the external electronic device via the first network 198 (e.g., a short-range communication network, such as Bluetooth™, wireless-fidelity (Wi-Fi) direct, or infrared data association (IrDA)) or the second network 199 (e.g., a long-range communication network, such as a cellular network, the Internet, or a computer network (e.g., LAN or wide area network (WAN)). These various types of communication modules may be implemented as a single component (e.g., a single chip), or may be implemented as multi components (e.g., multi chips) separate from each other. The wireless communication module 192 may identify and authenticate the electronic device 101 in a communication network, such as the first network 198 or the second network 199, using subscriber information (e.g., international mobile subscriber identity (IMSI)) stored in the subscriber identification module 196.


The antenna module 197 may transmit or receive a signal or power to or from the outside (e.g., the external electronic device) of the electronic device 101. According to an embodiment, the antenna module 197 may include an antenna including a radiating element composed of a conductive material or a conductive pattern formed in or on a substrate (e.g., PCB). According to an embodiment, the antenna module 197 may include a plurality of antennas. In such a case, at least one antenna appropriate for a communication scheme used in the communication network, such as the first network 198 or the second network 199, may be selected, for example, by the communication module 190 (e.g., the wireless communication module 192) from the plurality of antennas. The signal or the power may then be transmitted or received between the communication module 190 and the external electronic device via the selected at least one antenna. According to an embodiment, another component (e.g., a radio frequency integrated circuit (RFIC)) other than the radiating element may be additionally formed as part of the antenna module 197.


At least some of the above-described components may be coupled mutually and communicate signals (e.g., commands or data) therebetween via an inter-peripheral communication scheme (e.g., a bus, general purpose input and output (GPIO), serial peripheral interface (SPI), or mobile industry processor interface (MIPI)).


According to an embodiment, commands or data may be transmitted or received between the electronic device 101 and the external electronic device 104 via the server 108 coupled with the second network 199. Each of the electronic devices 102 and 104 may be a device of a same type as, or a different type, from the electronic device 101. According to an embodiment, all or some of operations to be executed at the electronic device 101 may be executed at one or more of the external electronic devices 102, 104, or 108. For example, if the electronic device 101 should perform a function or a service automatically, or in response to a request from a user or another device, the electronic device 101, instead of, or in addition to, executing the function or the service, may request the one or more external electronic devices to perform at least part of the function or the service. The one or more external electronic devices receiving the request may perform the at least part of the function or the service requested, or an additional function or an additional service related to the request, and transfer an outcome of the performing to the electronic device 101. The electronic device 101 may provide the outcome, with or without further processing of the outcome, as at least part of a reply to the request. To that end, a cloud computing, distributed computing, or client-server computing technology may be used, for example.


The electronic device 101 may transmit and/or receive a radio frequency (RF) signal representing a voice signal or data (e.g., a message, a picture, a video, a music file, or a game) by using an antenna, e.g., antenna module 197. The antenna may simultaneously transmit and receive signals belonging to different frequency bands. The electronic device may service a global communication band by using signals belonging to different frequency bands. For example, the electronic device may perform communication (e.g., a global positioning system (GPS), Legacy, and Wifi1) that uses signals belonging to a low frequency band (LB), and/or communication (e.g., Wifi2) that uses signals belonging to a high frequency band (HB).



FIG. 2 discloses antenna simultaneously transmitting and receiving signals belonging to different frequency bands.


Communication Module


FIG. 2 is a block diagram 200 of the electronic device 101 for supporting a legacy network communication and a 5G network communication according to certain embodiments. Referring to FIG. 2, the electronic device 101 may include a first communication processor 212, a second communication processor 214, a first radio frequency integrated circuit (RFIC) 222, a second RFIC 224, a third RFIC 226, a fourth RFIC 228, a first radio frequency front end (RFFE) 232, a second RFFE 234, a first antenna module 242, a second antenna module 244, and an antenna 248. The electronic device 101 may further include the processor 120 and the memory 130. The network 199 may include a first network 292 and a second network 294.


The electronic device 101 may service a global communication band by using signals belonging to different frequency bands. For example, the electronic device may perform communication that uses signals belonging to a legacy network 292, and/or communication that uses signals belonging to a second cellular network 294.


The electronic device 101 may further include at least one of the components illustrated in FIG. 1, and the network 199 may further include at least one another network. The first communication processor 212, the second communication processor 214, the first RFIC 222, the second RFIC 224, the fourth RFIC 228, the first RFFE 232, and the second RFFE 234 may constitute at least a portion of the wireless communication module 192. The fourth RFIC 228 may be omitted or may be included at a part of the third RFIC 226.


The first communication processor 212 may establish a communication channel of a band that is to be used for wireless communication with the first network 292, and may support legacy network communication through the established communication channel. According to certain embodiments, the first network may be a legacy network including 2-generation (2G), 3G, 4G, or long-term evolution (LTE). The second communication processor 214 may establish a communication channel corresponding to a designated one (e.g., about 6 GHz to about 60 GHz) of bands that are to be used for wireless communication with the second network 294, and may support 5G network communication through the established communication channel. According to certain embodiments, the second network 294 may be a 5G network defined by a 3GPP. In addition, according to an embodiment, the first communication processor 212 or the second communication processor 214 may establish a communication channel corresponding to another designated one (e.g., about 6 GHz or less) of bands that are to be used for wireless communication with the second network 294, and may support 5G network communication through the established communication channel. According to an embodiment, the first communication processor 212 and the second communication processor 214 may be implemented in a single chip or a single package. According to certain embodiments, the first communication processor 212 or the second communication processor 214 may be disposed in a single chip or a single package together with the processor 120, the auxiliary processor 123 of FIG. 1, or the communication module 190. For example, the processor 120 and the first communication processor 212, or the processor 120 and the second communication processor 214 may be coupled to each other.


The first RFIC 222 may convert a baseband signal generated by the first communication processor 212 into a radio frequency signal of about 700 MHz to about 3 GHz used for the first network 292 (e.g., the legacy network) during transmission of signals. An RF signal may be acquired from the first network 292 (e.g., the legacy network) through an antenna (e.g., the first antenna module 242) and the acquired RF signal may be preprocessed through an RFFE (e.g., the first RFFE 232), during reception of signals. The first RFIC 222 may convert the preprocessed RF signal to a baseband signal such that the preprocessed RF signal is processed by the first communication processor 212.


The second RFIC 224 may convert a baseband signal generated by the first communication processor 212 or the second communication processor 214 to an RF signal (hereinafter, a 5G sub6 RF signal) of a Sub6 band (e.g., about 6 GHz or less) used for the second network 294 (e.g., the 5G network) during transmission of signals. A 5G Sub6 RF signal may be acquired from the second network 294 (e.g., the 5G network) through an antenna (e.g., the second antenna module 244) and the acquired RF signal may be preprocessed through an RFFE (e.g., the second RFFE 234), during reception of signals. The second RFIC 224 may convert the preprocessed 5G Sub6 RF signal to a baseband signal such that the preprocessed 5G Sub6 RF signal is processed by a corresponding one of the first communication processor 212 or the second communication processor 214.


The third RFIC 226 may convert a baseband signal generated by the second communication processor 214 into an RF signal (hereinafter, a 5G Above6 RF signal) of a 5G Above6 band (e.g., about 6 GHz to about 60 GHz) that is to be used for the second network 294 (e.g., the 5G network). A 5G Above6RF signal may be acquired from the second network 294 (e.g., the 5G network) through an antenna (e.g., the antenna 248) and may be preprocessed through a third RFFE 236 during reception of signals to be converted to an intermediate frequency signal (IF) (e.g., about 13 GHz to about 17 GHz). The third RFIC 226 may convert the RF signal obtained through the conversion to a baseband signal such that the RF signal is processed by the second communication processor 214. According to an embodiment, the third RFFE 236 may be included at a part of the third RFIC 226.


According to an embodiment, the electronic device 101 may further include the fourth RFIC 228. As shown in FIG. 2, the fourth RFIC 228 may be formed separately from the third RFIC 226. However, the disclosure is not limited thereto, and the fourth RFIC 228 may be included in the third RFIC 226. The fourth RFIC 228 may be directly connected to the processor 120 through PCIe. In this case, the fourth RFIC 228 may convert the baseband signal generated by the second communication processor 214 into an RF signal (hereinafter, an IF signal) of an intermediate frequency band (e.g., about 9 GHz to about 11 GHz), and then may deliver the IF signal to the third RFIC 226. The third RFIC 226 may covert the IF signal to a 5G Above6 RF signal. A 5G Above6 RF signal may be received from the second network 294 (e.g., the 5G network) through an antenna (e.g., the antenna 248) and may be converted to the IF signal by the third RFIC 226. The fourth RFIC 228 may convert the IF signal to a baseband signal such that the baseband signal is processed by the second communication processor 214.


The first RFIC 222 and the second RFIC 224 may be implemented as at least a portion of a single chip or a single package. According to an embodiment, the first RFFE 232 and the second RFFE 234 may be implemented as at least a portion of a single chip or a single package. According to an embodiment, at least one of the first antenna module 242 or the second antenna module 244 may be omitted or coupled to another antenna module to process RF signals of a plurality of corresponding bands.


The third RFIC 226 and the antenna 248 may be disposed in the same substrate to constitute a third antenna module 246. For example, the wireless communication module 192 or the processor 120 may be disposed in a first substrate (e.g., a main PCB). The third RFIC 226 may be disposed in a partial area (e.g., a lower surface) of a second substrate (e.g., a sub-PCB) that is separate from the first substrate and the antenna 248 may be disposed in another partial area (e.g., an upper surface) to constitute the third antenna module 246. According to an embodiment, the antenna 248, for example, may include an antenna array that may be used for beam forming. The length of a transmission line between the third RFIC 226 and the antenna 248 can be reduced by arranging the third RFIC 226 and the antenna 248 in the same substrate. For example, this can reduce loss of a signal of a high-frequency band (e.g., about 6 GHz to about 60 GHz) used for the 5G network communication due to the transmission line. Accordingly, the electronic device 101 can improve the quality or speed of the communication with the second network 294 (e.g., the 5G network).


The second network 294 (e.g., the 5G network) may be operated independently from (e.g., Stand-Alone SA) or in conjunction (e.g., Non-Stand Alone NSA) with the first network 292 (e.g., the legacy network). For example, only an access network (e.g., a 5G radio access network (RAN) or a next generation (NG) RAN) may be present in the 5G network, and a core network (e.g., a next generation core (NGC)) may not be present. The electronic device 101 may access an access network of the 5G network, and then, may access an external network (e.g., the internet) under the control of a core network (e.g., an evolved packed core (EPC)) of the legacy network. Protocol information (e.g., LTE protocol information) for communication with the legacy network or protocol information (e.g., a new radio (NR) protocol information) for communication with the 5G network may be stored in a memory 230, and be accessed by another component (e.g., the processor 120, the first communication processor 212, or the second communication processor 214).


The placement of the antenna, 242, 244, and 246 presents a number of issues. Generally speaking, the front surface has very little room because of the display, and front facing cameras. It also may not be easy to place an antenna in the interior of the electronic device due to the amount of space.


To allow the electronic device to support new frequency bands, when the number of radiators included in the electronic device may increase but as space of the electronic device decrease, a radiation performance of the antenna in the interior may decrease.


Housing


FIGS. 3A and 3B describe the front and rear of the housing, while FIG. 4 describes the interior of the housing.



FIG. 3A is a perspective view of a front surface of an electronic device 300 (e.g., the electronic device 101 of FIG. 1) according to an embodiment. FIG. 3B is a perspective view of a rear surface of the electronic device 300 according to an embodiment.


Referring to FIGS. 3A and 3B, the electronic device 300 according to an embodiment may include a housing 310 including a first surface (or a front surface) 310A, a second surface (or a rear surface) 310B, and a side surface 310C surrounding a space between the first surface 310A and the second surface 310B. In another embodiment (not illustrated), the housing may refer to a structure that defines some of the first surface 310A, the second surface 310B, and the side surface 310C of FIG. 1. According to an embodiment, the first surface 310A may be defined by a front plate 302 (e.g., a glass plate or a polymer plate including various coating layers), at least a portion of which is substantially transparent. The second surface 310B may be defined by a substantially opaque rear plate 311. The rear plate 311, for example, may be formed of coated or colored glass, ceramics, a polymer, a metal (e.g., aluminum, stainless steel (STS), or magnesium), or a combination of at least two thereof. The side surface 310C may be coupled to the front plate 302 and the rear plate 311, and may be defined by a side bezel structure (or ‘a side member’) 318 including a metal and/or a polymer. In some embodiments, the rear plate 311 and the side bezel structure 318 may be integrally formed and may include the same material (e.g., a metallic material such as aluminum).


In the illustrated embodiment, the front plate 302 may include two first areas 310D that are deflected from the first surface 310A toward the rear plate 311 and extend seamlessly, at opposite ends of a long edge of the front plate 302. In the illustrated embodiment (see FIG. 3B), the rear plate 311 may include two second areas 310E that are deflected from the second surface 310B toward the front plate 302 and extend seamlessly, at opposite ends of a long edge of the rear plate 311. In some embodiments, the front plate 302 (or the rear plate 311) may include only one of the first areas 310D (or the second areas 310E). In other embodiment, some of the first areas 310D or the second areas 310E may not be included. In the embodiments, when viewed from a side of the electronic device 300, the side bezel structure 318 may have a first thickness (width) on a side surface, on which neither the first areas 310D nor the second areas 310E are included, and may have a second thickness that is smaller than the first thickness on a side surface, on which the first areas 310D or the second areas 310E are included.


The first surface 310A is primarily occupied by the display 301, sensor module 304, cameras 305, light emitting elements 306, and an audio module 314. Accordingly, there is very little room on the first surface 310A for the antenna.


Rather, at least one antenna radiator (e.g., a conductive pattern) may be disposed in the side member (e.g., the side bezel structure 318 of FIG. 3) of the housing 310 of the electronic device 300, the two first areas 310D deflected from the first surface 310A of the front plate 302 toward the rear plate 311 and extending seamlessly, or the two second areas 310E deflected from the second surface 310B of the rear plate 311 toward the front plate 302 and extending seamlessly.


In an embodiment, at least one antenna radiator may radiate a signal of a specific frequency band. In an embodiment, at least one antenna radiator may be an auxiliary radiator. As an example, at least one antenna radiator may radiate a signal belonging to a 5G Sub-6 frequency band of about 3.5 GHz to about 6 GHz, such as n41, n78, and/or n79. As another example, at least one antenna radiator may radiate a frequency of a Wi-Fi frequency band. The Wi-Fi frequency band may include a frequency band, such as 802.11a and/or 802.11b.


In an embodiment, at least one antenna radiator may be a main radiator. In an embodiment, some of frequency bands radiated by the main radiator and some frequency bands radiated by the auxiliary radiator may be the same, and the remaining ones thereof may be different.


In an embodiment, as another example, at least one antenna radiator may radiate a frequency of an mmWave frequency band. For example, the mmWave frequency band may include a frequency band, such as about 24 to 34 GHz and/or about 37 to 44 GHz. As another example, at least one antenna radiator may radiate a frequency of a frequency band of 11ay.


According to an embodiment, the electronic device 300 may include at least one of a display 301 (e.g., the display device 160 of FIG. 1), audio modules 303, 307, and 314 (e.g., the audio module 170 of FIG. 1), sensor modules 304, 316, and 319 (e.g., the sensor module 176 of FIG. 1), camera modules 305, 312, and 313 (e.g., the camera module 180 of FIG. 1), a key input device 317, a light emitting element 306, and connector holes 308 and 309.

The display 301, for example, may be exposed through considerable portions of the front plate 302. In some embodiments, at least a portion of the display 301 may be exposed through the front plate 302 defining the first surface 310A, and the first areas 310D of the side surface 310C. In some embodiments, corners of the display 301 may have a shape that is substantially the same as the adjacent outer shape of the front plate 302. In other embodiments, in order to expand the area, by which the display 301 is exposed, the intervals between the outskirts of the display 301 and the outskirts of the front plate 302 may be substantially the same.


In other embodiments (not illustrated), a portion of the screen display area of the display 301 may have a recess or an opening, and may include at least one of the audio module 314, the sensor module 304, the camera module 305, and the light emitting element 306, which are aligned with the recess or the opening. In other embodiments (not illustrated), at least one of the audio module 314, the sensor module 304, the camera module 305, the fingerprint sensor 316, and the light emitting element 306 may be included on the rear surface of the screen display area of the display 301. In other embodiments (not illustrated), the display 301 may be coupled to or be disposed to be adjacent to a touch detection circuit, a pressure sensor that may measure the strength (the pressure) of a touch, and/or a digitizer that detects a stylus pen of a magnetic field type. In some embodiments, at least a portion of the sensor modules 304 and 319 and/or at least a portion of the key input device 317 may be disposed in the first areas 310D and/or the second areas 310E.


The audio modules 303, 307, 314 may include the microphone hole 303 and the speaker holes 307 and 314. A microphone for acquiring external sounds may be disposed in the microphone hole 303, and in some embodiments, a plurality of microphones may be disposed to detect the direction of a sound. The speaker holes 307 and 314 may include the external speaker hole 307 and the communication receiver hole 314. In some embodiments, the speaker holes 307 and 314 and the microphone hole 303 may be implemented by one hole or a speaker may be included while the speaker holes 307 and 314 are not employed (e.g., a piezoelectric speaker).


The sensor modules 304, 316, and 319 may generate an electrical signal or a data value corresponding to an operational state of the interior of the electronic device 300 or an environmental state of the outside. The sensor modules 304, 316, and 319, for example, may include the first sensor module 304 (e.g., a proximity sensor) and/or a second sensor module (not illustrated) (e.g., a fingerprint sensor) disposed on the first surface 310A of the housing 310, and/or the third sensor module 319 (e.g., a HRM sensor) and/or the fourth sensor module 316 (e.g., a fingerprint sensor) disposed on the second surface 310B of the housing 310. The fingerprint sensor may be disposed not only on the first surface 310A (e.g., the display 301) but also on the second surface 310B of the housing 310. The electronic device 300 may further include a sensor module (not illustrated), for example, at least one of a gesture sensor, a gyro sensor, an atmospheric pressure sensor, a magnetic sensor, an acceleration sensor, a grip sensor, a color sensor, an infrared (IR) sensor, a biometric sensor, a temperature sensor, a humidity sensor, or the illumination sensor 304.


The camera modules 305, 312, and 313 may include the first camera device 305 disposed on the first surface 310A of the electronic device 300, and the second camera device 312 and/or the flash 313 disposed on the second surface 310B. The camera modules 305 and 312 may include one or a plurality of lenses, an image sensor, and/or an image signal processor. The flash 313, for example, may include a light emitting diode or a xenon lamp. In some embodiments, two or more lenses (an infrared ray camera or a wide angle/telephoto lens), and image sensors may be disposed on one surface of the electronic device 300.


The key input device 317 may be disposed on the side surface 310C of the housing 310. In another embodiment, the electronic device 300 may not include some or all of the above-mentioned key input devices 317, and the key input devices 317, which are not included, may be implemented in different forms, such as a soft key, on the display 301. In some embodiments, the key input device may include the sensor module 316 disposed on the second surface 310B of the housing 310.


The light emitting element 306, for example, may be disposed on the first surface 310A of the housing 310. The light emitting element 306, for example, may provide state information on the electronic device 300 in the form of light. In other embodiments, the light emitting element 306, for example, may provide a light source that interworks with an operation of the camera module 305. The light emitting element 306, for example, may include an LED, an IR LED, and a xenon lamp.


The connector holes 308 and 309 may include the first connector hole 308 that may accommodate a connector (e.g., a USB connector) for transmitting and receiving electric power and/or data to and from an external electronic device and/or the second connector hole (e.g., an earphone jack) 309 that may accommodate a connector for transmitting and receiving an audio signal to and from the external device.



FIG. 4 is an exploded perspective view 400 of an electronic device (e.g., the electronic device 300 of FIG. 3A and/or FIG. 3B) according to an embodiment. Referring to FIG. 4, the electronic device 300 may include a side bezel structure 410 (e.g., the side bezel structure 318 of FIG. 3A), a first support member 411 (e.g., the bracket), a front plate 420, a display 430 (e.g., the display 301 of FIG. 3A), a PCB 440, a battery 450, a second support member 460 (e.g., the rear case), a short range antenna 470, and/or a rear plate 480 (e.g., the rear plate 311 of FIG. 3). In some embodiments, at least one (e.g., the first support member 411 or the second support member 460) of the elements may be omitted from the electronic device 300 or another component may be additionally included in the electronic device 300. At least one of the components of the electronic device 300 may be the same as or similar to at least one of the components of the electronic device 300 of FIG. 1 or 2, and a repeated description thereof will be omitted.


The first support member 411 may be disposed in the interior of the electronic device 300 to be connected to the side bezel structure 410 or to be integrally formed with the side bezel structure 410. The first support member 411, for example, may be formed of a metal material and/or a nonmetal material (e.g., a polymer). The display 430 may be coupled to one surface of the first support member 411, and the PCB 440 may be coupled to an opposite surface of the first support member 411.


In an embodiment, a processor (e.g., the processor 120 of FIG. 1), a memory (e.g., the memory 130 of FIG. 1), and/or an interface (e.g., the interface 177 of FIG. 1) may be mounted on the PCB 440. The processor 120, for example, may include one or more of a central processing unit (CPU), an application processor (AP), a graphic processing unit (GPU), an image signal processor (ISP), a sensor hub processor (SHP), or a communication processor (CP). The memory, for example, may include a volatile and/or nonvolatile memory. The interface, for example, may include a high definition multimedia interface (HDMI), a universal serial bus (USB) interface, an SD card interface, and/or an audio interface. The interface, for example, may electrically or physically connect the electronic device 300 to an external electronic device (e.g., the electronic device 102 and 104 of FIG. 1), and may include a USB connector, an SD card/MMC connector, or an audio connector.


The battery 450 is a device for supplying electric power to at least one component of the electronic device 300, and for example, may include a primary battery that cannot be recharged, a secondary battery that may be recharged, or a fuel cell. At least a portion of the battery 450, for example, may be disposed on the same plane as the PCB 440. The battery 450 may be integrally disposed in the interior of the electronic device 300, and may be disposed to be detachable from the electronic device 300.


The short range antenna 470 may be disposed between the rear plate 480 and the battery 450. The antenna 470, for example, may include a near field communication (NFC) antenna, a wireless charging antenna, and/or a magnetic secure transmission (MST) antenna. The antenna 470, for example, may perform short-range communication with an external device, or may wirelessly transmit and receive electric power that is necessary for charging. In another embodiment, an antenna structure may be formed by one or a combination of the side bezel structure 410 and/or the first support member 411.



FIG. 5 is a cross-sectional view 500 of an electronic device (e.g., the electronic device 101 of FIG. 1) according to an embodiment. The display side is facing down (−Z), while the rear surface is facing upwards (+Z).


The electronic device 101 includes an antenna module 502 that is disposed in a space within the housing. The antenna module 502 includes at least one antenna element that is configured to transmit and receive a signal having a first carrier frequency. A nonconductive member 530 faces at least one surface of the antenna module 502. A conductive pattern 511 is disposed between the nonconductive member 530 and the rear plate 550.


A housing 501 may include a front plate 560 (e.g., the front plate 420 of FIG. 4), a rear plate 550 (e.g., the rear plate 480 of FIG. 4), and/or a side member 542 (e.g., the side bezel structure 410 of FIG. 4). The front plate 560 may face a first direction (e.g., the −Z axis direction). The rear plate 550 may face a second direction (e.g., the +Z axis direction) that is an opposite direction to the first direction (e.g., the −Z axis direction). The side member 542 may surround a space between the front plate 560 and the rear plate 550. The side member 542 may connect one side of the front plate 560 and one side of the rear plate 550.


The side member 542 may include a conductive member 541 (e.g., the first support member 411 of FIG. 4). In an embodiment, the side member 542 may be coupled to or integrally formed with the conductive member 541. The conductive member 541 may be disposed in the space. For example, the conductive member may include aluminum, stainless steel, titanium, or nickel.


An antenna module 502 (e.g., the third antenna module 246 of FIG. 2) may be disposed in the space between the front plate 560 and the rear plate 550 of the housing 501. The antenna module 502 may process a signal of a specific frequency. For example, the antenna module 502 may process an mmWave signal.


A nonconductive member 530 may face at least one surface of the antenna module 502. The nonconductive member 530 may include a polymer material. The nonconductive member 530 may be a first area 510 of the conductive member 541 around the antenna module 502 and an injection-molded product disposed around the first area 510. For example, at least a portion of the nonconductive member 530 may be disposed in the first direction (the −Z axis direction) from the first area 510, and the remaining portions of the nonconductive member 530 may be disposed in a third direction (the +Y axis direction) from the first area 510. The nonconductive member 530 may be disposed to be spaced apart from the antenna module 502. For example, a space 531 filled with air may be formed between the antenna module 502 and the nonconductive member 530.


The nonconductive member 530 may support the antenna module 502 such that the antenna module 502 is mounted at a specific location of an interior space of the housing 501. For example, the antenna module 502 may be supported to be disposed in a second direction (the +Z axis direction) of the nonconductive member 530. In this case, the antenna module 502 may form a beam pattern such that the beam pattern faces the side member 542.


The nonconductive member 530 may be adjacent to the side member 542 of the housing 501, between the side member 542 and the antenna module 502.


A space 531 may be formed between the nonconductive member 530 and the antenna module 502. For example, at least a partial area of a surface of the nonconductive member 530, which faces the antenna module 502 of the nonconductive member 530, may be convex. The convex area of the nonconductive member 530 may change a travel path of a radio frequency signal radiated from the antenna module 502. The nonconductive member 530 may contact the side member 542 and the conductive member 541. One surface of the nonconductive member 530 may include another convex area, and a separating wall located between the at least a partial area and the another partial area.


A conductive pattern 511 may be disposed between the nonconductive member 530 and the rear plate 550. The conductive pattern 511 may be disposed in the second direction (e.g., the +Z axis direction) closer to the rear plate 550 than to the front plate 560. In an embodiment, the conductive pattern 511 may be disposed to be spaced apart from the antenna module 502. For example, the conductive pattern 511 may be adjacent to a surface of the antenna module 502, facing the second direction (the +Z axis direction). For example, the conductive pattern 511 may be formed by a flexible printed circuit board (FPCB). As another example, the conductive pattern 511 may be formed through laser direct structuring (LDS).


The conductive pattern 511 may be disposed in the first area 510 (e.g., the first area 310D of FIG. 3A) of the nonconductive member 530. The first area 510, for example, may be at least a partial area of a bending area, in which the rear plate 550 extends in the third direction (e.g., the +Y axis direction) and is bent in the first direction (e.g., the −Z axis direction). The first area 510 may be an area that does not overlap the side member 542 when the antenna module 502 is viewed in the +Y axis direction. The conductive pattern 511 may be disposed in the first area 510.


The conductive pattern 511 may change a radiation pattern of a first signal belonging to the first frequency band. The first frequency band, for example, may be a frequency band of about 15 GHz to about 100 GHz. For example, the first frequency band may include a 5G mmWave band.


The conductive pattern 511 may change the first radiation pattern that is the radiation pattern of the first signal. The radiation pattern of the first signal may initially be in the +Y axis direction, or perpendicular to the directions that the front plate and rear plate face, the Z axis. For example, the conductive pattern 511 may reflect at least a portion of the first radiation pattern in the +Z axis direction. For example, the conductive pattern 511 may perform a role of a reflector that reflects the first signal in the +Y axis direction.


The conductive pattern 511 may use a common ground with the antenna module 502. For example, the conductive pattern 511 may be connected to a ground layer disposed in a main PCB (e.g., the PCB 440 of FIG. 4). As another example, the conductive pattern 511 may be connected to the conductive member 541 (e.g., a metal bracket) in the interior of the electronic device 101.


The conductive pattern 511 may radiate a second signal belonging to a second frequency band that is different from the first frequency band. The second frequency band may be a frequency band of about 3 GHz to about 6 GHz. For example, the second frequency band may be a 5G Sub-6 frequency band.


A nonconductive member 521 may be formed at at least a portion of a second part 520 of the front plate 560. The nonconductive member 521 may be formed between the front plate 560 and the side member 542. The nonconductive member 521 may be formed in a direction (e.g., direction A) between the first direction (the −Z axis direction) and the third direction (direction B).


A radiation performance in the first direction (the −Z axis direction) or to the front side of the electronic device 101 may be decreased by the conductive material included in the conductive member 541 and a display 570. The nonconductive member 521 may enhance the radiation performance to the front side by forming a path, in which the electronic device 101 may radiate a signal to the front side.



FIG. 6 is a polar graph 600 illustrating a radiation pattern 610 of a first frequency band according to a comparative example and a radiation pattern 620 of the first frequency band according to an embodiment.


The radiation pattern 610 of the first frequency band of the comparative example may perform a main radiation to the rear plate (e.g., the second direction (e.g., the +Z axis direction) that is a direction of the rear plate 550 of FIG. 5) in a vertical mounting structure (e.g., a structure, in which the antenna module 502 of FIG. 5 is mounted to face the third direction (e.g., the +Y axis direction) of the antenna module (e.g., the antenna module 502 of FIG. 5). In the comparative example, a radiation performance in a direction of the front side of the electronic device 101, which is the first direction (the −Z axis direction) of the electronic device (e.g., the electronic device 101 of FIG. 1) may be decreased. In the comparative example, an overall coverage performance of the electronic device 101 may be decreased due to the decreasing of the radiation performance in the first direction (the −Z axis direction) to a specific level or less.


The electronic device 101 may include a conductive pattern (e.g., the conductive pattern 511 of FIG. 5) that may change a direction of the radiation pattern in an injection-molding area (e.g., the first area 510 of the nonconductive member 530 of FIG. 3) proximate to the antenna module 502. The conductive pattern 511 may enhance the coverage performance of the electronic device 101 in a specific direction by changing the direction of the radiation pattern of the electronic device 101. The radiation pattern 620 according to an embodiment may enhance the radiation performance in the first direction (the −Z axis direction) and/or the third direction (the +Y axis direction) as compared with the radiation pattern 610 according to the comparative example.


In an embodiment, the radiation performance in the first direction (the −Z axis direction) and/or the third direction (the +Y axis direction) of the electronic device 101 may be enhanced by using the conductive pattern 511. For example, the radiation performance in direction A may be enhanced from about 1.9 dB to about 3.9 dB by about 2 dB, by the conductive pattern 511. For example, a size of the radiation pattern 620 according to an embodiment may be increased in direction A at a specific first point 630 by about 2 dB as compared with a size of the radiation pattern 610 according to the comparative example. For example, by the conductive pattern 511, radiation characteristics of a vertical polarization component that is radiated in direction A and shows polarization characteristics in the first direction (e.g., the −Z axis direction) and/or the second direction (e.g., the +Z axis direction) may be enhanced by about +0.8 dB to about +1.2 dB, and radiation characteristics of a horizontal polarization component that shows polarization characteristics in the +X axis direction and/or the −X axis direction may be enhanced by about +1.8 dB to about +2.2 dB.


In an embodiment, a gain value in a reference direction (a bore sight) of the electronic device 101 may be enhanced by about +0.7 dB in a vertical direction and about +2 dB in a horizontal direction, by the conductive pattern 511. By the conductive pattern 511, radiation characteristics of a vertical polarization component that is radiated in direction B (e.g., the third direction (the +Y axis direction)) and shows polarization characteristics in the first direction (e.g., the −Z axis direction) and/or the second direction (the +Z axis direction) may be enhanced by about +0.6 dB to about +0.8 dB. By the conductive pattern 511, radiation characteristics of a horizontal polarization component that shows polarization characteristics in the +X axis direction and/or the −X axis direction may be enhanced by about +1.8 dB to about +2.2 dB. Due to an influence of the conductive member (e.g., the side member 542 of FIG. 5), the vertical polarization component may be influenced by the radiation characteristics, and the horizontal polarization component may be influenced less by the radiation characteristics as compared with the vertical polarization component.



FIG. 7 is a view 700 illustrating the conductive pattern 511 of the electronic device (e.g., the electronic device 101 of FIG. 1) according to an embodiment.


The conductive pattern 511 may be adjacent to the antenna module 502. The conductive pattern 511 may face the the side member (e.g., the side member 542 of FIG. 5) of the housing, rather than to face the antenna module 502. The conductive pattern 511 may be disposed on the nonconductive member 530 to not overlap the antenna module 502 when viewed in the +Y axis direction.


The conductive pattern 511 may have a first length D1 in a fourth direction (e.g., the X axis direction). For example, the fourth direction (e.g., the X axis direction) may be a direction that extends along the side member 542. The first length D1 may be set according to the second frequency band of the second signal. For example, when the second frequency band is a band of 5G Sub-6, the first length D1 may be about 16 mm, or between 15.5 mm to 16.5 mm.


The conductive pattern 511 may have a second length D2 in the third direction (e.g., the +X axis direction). The second length D2 may be set according to a width of the nonconductive member 530 in the third direction (+X axis direction) and/or a mounting method of the conductive pattern 511. For example, the second length D2 may be about 1 mm to about 3 mm.



FIG. 8 is a view 800 illustrating the conductive pattern 511 of the electronic device (e.g., the electronic device 101 of FIG. 1) according to an embodiment.


The conductive pattern 511 may be formed by a flexible printed circuit board (FPCB). The conductive pattern 511 may be disposed to extend along at least one surface of the antenna module 502. For example, the conductive pattern 511 may extend along one of the side surfaces of the antenna module 502, which is disposed along the third direction (the +X axis direction). The conductive pattern 511 may be disposed on the nonconductive member (e.g., the nonconductive member 530 of FIG. 5).


The conductive pattern 511 may be located on the nonconductive member (e.g., the nonconductive member 530 of FIG. 5). The antenna module 502 may be mounted to face the side member 542 of the electronic device 101. The conductive pattern 511 may be formed through an FPCB or an LDS. The conductive pattern 511 may be connected to the wireless communication circuit (e.g., the wireless communication module 192 of FIG. 1) disposed in the PCB 440 to be operated as an antenna. The conductive pattern 511 may be fed with electric power for radiating a second signal, from the wireless communication circuit 192. The wireless communication circuit 192 may be connected to the conductive pattern 511 through a first connector 820, such as a side contact, to feed electric power of the second signal. For example, the first connector 820 may be a C-clip. According to an embodiment, the conductive pattern 511 may be connected to the wireless communication circuit 192 through the first connector 820 to be operated as an antenna.


The conductive pattern 511 may be connected to the ground through a second connector 830. The second connector 830 may be disposed or omitted. For example, the conductive pattern 511 may be connected to the ground of a structure of a planar inverted-F antenna (PIFA) through the second connector 830. For example, the second connector 830 may be connected to a ground layer 810 of the PCB 440. As another example, the second connector 830 may be connected to another ground layer, such as a metal bracket (e.g., the conductive member 541 of FIG. 5) to be used as a ground part of the conductive pattern 511.



FIG. 9 is a view 900 illustrating a radiation pattern 910 of a second frequency band of the electronic device (e.g., the electronic device 101 of FIG. 1) according to an embodiment.


A conductive pattern (e.g., the conductive pattern 511 of FIG. 7) may be disposed in a nonconductive member (e.g., the nonconductive member 530 of FIG. 7) that faces and/or supports an antenna module (e.g., the antenna module 502 of FIG. 7). The radiation pattern 910 may be formed when a signal belonging to a second frequency band is fed to the conductive pattern 511. The radiation pattern 910 may be formed uniformly in a rearward direction (e.g., the +Z axis direction) and a forward direction (e.g., the −Z axis direction) of the electronic device 101.



FIG. 10 is a graph 1000 illustrating a reflection efficiency as measured in dB of a second frequency band (3 GHz-4 GHz) as a function of frequency.


The conductive pattern (e.g., the conductive pattern 511 of FIG. 7) may have the first length D1 in the third direction (e.g., the X axis direction of FIG. 7) along the side member (e.g., the side member 542 of FIG. 5). A graph 1010 may be a simulation result for the second frequency band using the conductive pattern 511. For example, the second frequency band may include an n78 frequency band of a 5G Sub-6 frequency band. The n78 frequency band, for example, may be a frequency band of about 3.3 GHz to about 3.8 GHz. For example, the first length D1 may be about 16 mm. The reflection efficiency of the graph 1010 may be about −3 dB at about 3.7 GHz. For example, the conductive pattern 511 may be an antenna radiator that radiates the n78 frequency band. A length of the nonconductive member (e.g., the nonconductive member 530 of FIG. 7) in the third direction (the X axis direction) may be about 16 mm to 40 mm such that the conductive pattern 511 is disposed. Accordingly, the antenna radiator that radiates a signal of the second frequency band may be implemented in a space on the nonconductive member 530 by adjusting a length of the conductive pattern 511 in the third direction (the X axis direction).



FIG. 11 is a graph 1100 illustrating a reflection efficiency of a second frequency band of the electronic device (e.g., the electronic device 101 of FIG. 1) according to an embodiment.


The second frequency band may include a Wi-Fi frequency band. For example, the second frequency band may be a 802.11 frequency band having a frequency of about 2.4 GHz.


A graph 1110 may have a value 1111 of a reflection efficiency at a frequency of about 2.4 GHz. The value 1111 of the reflection efficiency may be about −6 dB. Accordingly, an antenna radiator that radiates a signal of a Wi-Fi frequency band may be implemented in a space on the nonconductive member (e.g., the nonconductive member 530 of FIG. 7).


The conductive pattern can be formed on a printed circuit board (FPCB). FIGS. 12A-12C describes conductive patterns disposed on an FPCB, thereby forming a FPCB antenna



FIG. 12A is a view illustrating a flexible printed circuit board (FPCB) antenna 1200 of an electronic device (e.g., the electronic device 101 of FIG. 1) according to an embodiment.


The flexible printed circuit board (FPCB) antenna 1200 may include a first conductive pattern 1210 (e.g., the conductive pattern 511 of FIG. 5) and/or a second conductive pattern 1215.


The FPCB antenna 1200 may include the first conductive pattern 1210 and/or the second conductive pattern 1215. The FPCB antenna 1200 may be located on a nonconductive member (e.g., the nonconductive member 530 of FIG. 5).


The FPCB antenna 1200 may be disposed on the nonconductive member such that the second conductive pattern 1215 is disposed between the first conductive pattern 1210 and the antenna module 502. As another example, the second conductive pattern 1215 may be disposed on the nonconductive member to at least partially overlap the FPCB antenna 1200 between the first conductive pattern 1210 and the antenna module 502 when viewed in the +Z axis direction. The first conductive pattern 1210 may extend in the fourth direction (the +X axis direction) along the second conductive pattern 1215. For example, the second conductive pattern 1215 may decrease a radiation characteristic deviation of the first conductive pattern 1210 or the antenna module 502 even when an interval between the first conductive pattern 1210 and the antenna module 502 is changed.


The first conductive pattern 1210 may change at least a portion of the radiation pattern of a first signal belonging to the first frequency band of the antenna module 502.


When the FPCB antenna 1200 is disposed on the nonconductive member, the interval between the first conductive pattern 1210 and the antenna module 502 may be changed. The second conductive pattern 1215 may help maintain the interval between the first conductive pattern 1210 and the antenna module 502. The second conductive pattern 1215 may decrease a radiation characteristic deviation of the first conductive pattern 1210 due to a mounting error of the antenna module 502.



FIG. 12B is a view of the FPCB antenna 1200 of an electronic device (e.g., the electronic device 101 of FIG. 1) according to an embodiment.


The FPCB antenna 1200 may include a first conductive pattern 1220, the second conductive pattern 1215, and a dummy pattern 1230.


The first conductive pattern 1220 may extend in the +X axis direction along the second conductive pattern 1215 by a first length L1. The first conductive pattern 1220 may be electrically connected to a wireless communication circuit (e.g., the wireless communication module 192 of FIG. 1) to radiate a signal of the second frequency band. For example, the first length L1 may be set according to the second frequency band that is radiated by the first conductive pattern 1220. For example, when the first conductive pattern 1220 radiates a 5G Sub-6 frequency band, the first length L1 may be set to about 12 mm to about 20 mm.


The dummy pattern 1230 may include the FPCB antenna 1200. The dummy pattern 1230 may be disposed in the +X axis direction that is a direction, in which the first conductive pattern 1220 extends. The dummy pattern 1230 may be disposed to be spaced apart from the first conductive pattern 1220.


The dummy pattern 1230 may be in a ground state and/or a floating state. The dummy pattern 1230 may influence at least a portion of a radiation pattern of a first signal belonging to the first frequency band. For example, when the first frequency band is a 5G mmWave band, the dummy pattern 1230 may reflect the first signal that travels from the second conductive pattern 1215 in the second direction (the +Z axis direction), in the third direction (the +Y axis direction).


The dummy pattern 1230 may be disposed when a length of the first conductive pattern 1210 according to the second frequency band is smaller than a length of an antenna array included in the antenna module 502. The dummy pattern 1230 may enhance a radiation performance of the antenna module (e.g., the antenna module 502 of FIG. 5). In an embodiment, the dummy pattern 1230 may adjust a resonance frequency of the first conductive pattern 1220. The dummy pattern 1230 may maintain a radiation direction of the first conductive pattern 1220 in a modified form.

In an embodiment, the first conductive pattern 1240 may extend in the +X axis direction along the second conductive pattern 1215 by a second length L2. For example, the second length L2 may be set according to the second frequency band that is radiated by the first conductive pattern 1240.


In an embodiment, the plurality of dummy patterns 1250 and 1260 may be disposed in the FPCB antenna 1200. The plurality of dummy patterns 1250 and 1260 may be disposed to be spaced apart from each other. The dummy patterns 1250 and 1260 may be disposed in parallel to each other in the +X axis direction that is the direction, in which the first conductive pattern 1240 extends. The plurality of dummy patterns 1250 and 1260 may be disposed to be spaced apart from the first conductive pattern 1240.


In an embodiment, the plurality of dummy patterns 1250 and 1260 may be in a state, in which they are connected to the ground, and/or a floating state. The plurality of dummy patterns 1250 and 1260 may change at least a portion of the radiation pattern of the first signal belonging to the first frequency band of the antenna module 502. For example, when the first frequency band is a 5G mmWave band, the plurality of dummy patterns 1250 and 1260 may reflect the first signal that travels from the second conductive pattern 1215 in the second direction (the +Z axis direction), in the third direction (the +Y axis direction). According to an embodiment, the plurality of dummy patterns 1250 and 1260 may be two or more dummy patterns.

At least one space 531 may be formed in the nonconductive member 530. For example, a plurality of empty spaces 531a, 531b, 531c, and 531d may be formed in the nonconductive member 530. A plurality of shielding walls 532 may be formed to isolate the plurality of empty spaces 531a, 531b, 531c, and 531d. The plurality of shielding walls 532 may be disposed not to overlap antenna elements included in the antenna module 502.

The nonconductive member 530 may be formed by expanding a carrier. When the nonconductive member 530 is formed by expanding the carrier, the nonconductive member 530 may be disposed to overlap at least a portion of the PCB 440 in the first direction (the −Z axis direction) and/or the second direction (the +Z axis direction).

The connection member 1620, for example, may include a C-clip. The nonconductive member 530, for example, may be a rear cover. The conductive pattern 1410 may be disposed to extend from the via structure 1411 that protrudes from the nonconductive member 530 in the second direction (e.g., the +Z axis direction) and then extend in the fourth direction (e.g., the −Y axis direction). For example, the conductive pattern 1410 may be implemented through an FPCB or an LDS.

In an embodiment, the nonconductive member 530 may include the via structure 1411. The via structure 1411 may connect the FPCB antenna 1200 and the PCB 440. For example, when the conductive pattern 1410 is disposed in the nonconductive member 530 in a form of an FPCB and/or an LDS, the via structure 1411 may connect the PCB 440 and the conductive pattern 1410.


In an embodiment, a terminal 1510 may be disposed in the FPCB antenna 1200. The terminal 1510 may be connected to the PCB 440 through a connection member, such as a hole on the nonconductive member 530. For example, the terminal 1510 may be connected to the PCB 440 through the connection member, such as a C-clip.



FIG. 16 is a view 1600 of a matching circuit part 1601 of the PCB 440 of the electronic device (e.g., the electronic device 101 of FIG. 1) according to an embodiment.

In an embodiment, it may be identified that the electronic device 101, to which the conductive pattern (e.g., the conductive pattern 1410 of FIG. 14) and the matching circuit part (e.g., the matching circuit part 1601 of FIG. 16) of FIGS. 14 to 16 are applied, has a reflection efficiency of about −6.5 dB when the second frequency band is about 3.5 GHz. The electronic device 101 may form a resonance of about −6.5 dB at a frequency band of about 3.5 GHz. Furthermore, it may be identified in the graph 1700 that the reflection efficiency is maximum at a point 1710 and is at about 3.5 GHz and the reflection efficiency is increased at about 5 GHz.
