The disclosure relates to an antenna and an electronic device including the same.
With the development of wireless communication technology, electronic devices (e.g., electronic devices for communication) are commonly used in daily life, and thus use of contents is increasing exponentially. Due to the rapid increase of use of contents, network capacity is gradually reaching the limit thereof. After the commercialization of 4G (4th generation) communication systems, in order to meet the increasing demand for wireless data traffic, communication systems (e.g., a 5G (5th generation) communication system, a pre-5G communication system, or a new radio (NR)) that transmit and/or receive signals using a frequency of a high-frequency (e.g., the mmWave) band (e.g., a band in the range of 3 GHz to 300 GHz)) are being researched.
The next-generation wireless communication technology can actually transmit and receive wireless signals substantially using the mmWave band (e.g., a frequency band in the range of about 3 GHz to 100 GHz). An efficient mounting structure and a new antenna structure (e.g., an antenna module) corresponding thereto are being developed in order to overcome a high free-space loss due to frequency characteristics and to increase the gain of an antenna. The antenna structure may include an array antenna in which a variable number of antenna elements (e.g., conductive patches and/or conductive patterns) are disposed at regular intervals. These antenna elements may be disposed such that a beam pattern is formed in any one direction inside the electronic device. For example, the antenna structure may be disposed such that a beam pattern is formed toward at least a portion of the front surface, the rear surface, and/or the side surface in the inner space of the electronic device.
The electronic device may include an antenna that is disposed in the inner space and operates in a high-frequency band different from that of the above-described array antenna for fast short-range wireless communication with an external electronic device disposed nearby, and may be set to form a beam pattern in a specific direction. For example, the short-range communication may include 802.11ay, which is a type of LAN of a wireless LAN (WLAN) IEEE 802.11 set. 802.11ay is being developed as the next-generation short-range wireless communication because it uses a relatively wider bandwidth (about 8.64 GHz) than other short-range communication in a high-frequency band (e.g., about 60 GHz).
However, when the antenna structure operating in the mmWave band and the antenna structure operating in the 802.11ay band are separately configured and disposed in the inner space of the electronic device, it goes against the trend of slimming of electronic devices, and design restrictions of other electronic components may occur due to securing a space for arrangement of antenna structures.
Embodiments of the disclosure provide an antenna configured to modularize antennas operating in different high frequency bands into one structure, and an electronic device including the same.
Embodiments of the disclosure provide an antenna capable of contributing to slimming of an electronic device and an electronic device including the same.
Embodiments of the disclosure provide an antenna structure configured to operate in both an mmWave band and an 802.11ay band, and an electronic device including the same.
According to various example embodiments, an electronic device may include: a housing, an antenna structure disposed in the inner space of the housing, wherein the antenna structure includes: a substrate including a first substrate surface and a second substrate surface oriented in a direction opposite to the first substrate surface, and a first array antenna including a plurality of first chip antennas disposed at a specified interval in a first region of the first substrate surface, and a first wireless communication circuit disposed in the inner space and configured to transmit and/or receive a wireless signal of a first frequency band via the first array antenna.
The antenna structure according to various example embodiments of the disclosure can be helpful for slimming an electronic device and for increasing the degree of freedom of mounting for peripheral electronic components by disposing at least some of a plurality of antenna elements included in a first array antenna, which operates in a first high-frequency band (e.g., mmWave band), and a second array antenna, which operates in a second high frequency band (e.g., 802.11ay band), on a single substrate in the form of a chip antenna.
In addition, various effects directly or indirectly identified through disclosure may be provided.

The first communication processor 212 may include various processing circuitry and establish a communication channel of a band to be used for wireless communication with the first cellular network 292 and support legacy network communication through the established communication channel. According to various embodiments, the first cellular network may be a legacy network including a second generation (2G), 3G, 4G, or long term evolution (LTE) network. The second communication processor 214 may include various processing circuitry and establish a communication channel corresponding to a designated band (e.g., about 6 GHz to about 60 GHz) of bands to be used for wireless communication with the second cellular network 294, and support 5G network communication through the established communication channel. According to various embodiments, the second cellular network 294 may be a 5G network defined in 3GPP. Additionally, according to an embodiment, the first communication processor 212 or the second communication processor 214 may establish a communication channel corresponding to another designated band (e.g., about 6 GHz or less) of bands to be used for wireless communication with the second cellular network 294 and 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 various embodiments, the first communication processor 212 or the second communication processor 214 may be formed in a single chip or a single package with the processor 120, the auxiliary processor 123, or the communication module 190.
Upon transmission, the first RFIC 222 may convert a baseband signal generated by the first communication processor 212 to a radio frequency (RF) signal of about 700 MHz to about 3 GHz used in the first cellular network 292 (e.g., legacy network). Upon reception, an RF signal may be obtained from the first cellular network 292 (e.g., legacy network) through an antenna (e.g., the first antenna module 242) and be preprocessed through an RFFE (e.g., the first RFFE 232). The first RFIC 222 may convert the preprocessed RF signal to a baseband signal so as to be processed by the first communication processor 212.
Upon transmission, 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, 5G Sub6 RF signal) of a Sub6 band (e.g., 6 GHz or less) to be used in the second cellular network 294 (e.g., 5G network). Upon reception, a 5G Sub6 RF signal may be obtained from the second cellular network 294 (e.g., 5G network) through an antenna (e.g., the second antenna module 244) and be pretreated through an RFFE (e.g., the second RFFE 234). The second RFIC 224 may convert the preprocessed 5G Sub6 RF signal to a baseband signal so as to be processed by a corresponding communication processor 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 to an RF signal (hereinafter, 5G Above6 RF signal) of a 5G Above6 band (e.g., about 6 GHz to about 60 GHz) to be used in the second cellular network 294 (e.g., 5G network). Upon reception, a 5G Above6 RF signal may be obtained from the second cellular network 294 (e.g., 5G network) through an antenna (e.g., the antenna 248) and be preprocessed through the third RFFE 236. The third RFIC 226 may convert the preprocessed 5G Above6 RF signal to a baseband signal so as to be processed by the second communication processor 214. According to an embodiment, the third RFFE 236 may be formed as part of the third RFIC 226.
According to an embodiment, the electronic device 101 may include a fourth RFIC 228 separately from the third RFIC 226 or as at least part of the third RFIC 226. In this case, the fourth RFIC 228 may convert a baseband signal generated by the second communication processor 214 to an RF signal (hereinafter, an intermediate frequency (IF) signal) of an intermediate frequency band (e.g., about 9 GHz to about 11 GHz) and transfer the IF signal to the third RFIC 226. The third RFIC 226 may convert the IF signal to a 5G Above 6RF signal. Upon reception, the 5G Above 6RF signal may be received from the second cellular network 294 (e.g., a network) through an antenna (e.g., the antenna 248) and be converted to an IF signal by the third RFIC 226. The fourth RFIC 228 may convert an IF signal to a baseband signal so as to be processed by the second communication processor 214.
According to an embodiment, the first RFIC 222 and the second RFIC 224 may be implemented into at least part of a single package or a single chip. According to an embodiment, the first RFFE 232 and the second RFFE 234 may be implemented into at least part of a single package or a single chip. According to an embodiment, at least one of the first antenna module 242 or the second antenna module 244 may be omitted or may be combined with another antenna module to process RF signals of a corresponding plurality of bands.
According to an embodiment, the third RFIC 226 and the antenna 248 may be disposed at the same substrate to form a third antenna module 246. For example, the wireless communication module 192 or the processor 120 may be disposed at a first substrate (e.g., main PCB). In this case, the third RFIC 226 is disposed in a partial area (e.g., lower surface) of the first substrate and a separate second substrate (e.g., sub PCB), and the antenna 248 is disposed in another partial area (e.g., upper surface) thereof; thus, the third antenna module 246 may be formed. By disposing the third RFIC 226 and the antenna 248 in the same substrate, a length of a transmission line therebetween can be reduced. This may reduce, for example, a loss (e.g., attenuation) of a signal of a high frequency band (e.g., about 6 GHz to about 60 GHz) to be used in 5G network communication by a transmission line. Therefore, the electronic device 101 may improve a quality or speed of communication with the second cellular network 294 (e.g., 5G network).
According to an embodiment, the antenna 248 may be formed in an antenna array including a plurality of antenna elements that may be used for beamforming. In this case, the third RFIC 226 may include a plurality of phase shifters 238 corresponding to a plurality of antenna elements, for example, as part of the third RFFE 236. Upon transmission, each of the plurality of phase shifters 238 may convert a phase of a 5G Above6 RF signal to be transmitted to the outside (e.g., a base station of a 5G network) of the electronic device 101 through a corresponding antenna element. Upon reception, each of the plurality of phase shifters 238 may convert a phase of the 5G Above6 RF signal received from the outside to the same phase or substantially the same phase through a corresponding antenna element. This enables transmission or reception through beamforming between the electronic device 101 and the outside.
The second cellular network 294 (e.g., 5G network) may operate (e.g., stand-alone (SA)) independently of the first cellular network 292 (e.g., legacy network) or may be operated (e.g., non-stand alone (NSA)) in connection with the first cellular network 292. For example, the 5G network may have only an access network (e.g., 5G radio access network (RAN) or a next generation (NG) RAN and have no core network (e.g., next generation core (NGC)). In this case, after accessing to the access network of the 5G network, the electronic device 101 may access to an external network (e.g., 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 a legacy network or protocol information (e.g., new radio (NR) protocol information) for communication with a 5G network may be stored in the memory 130 to be accessed by other components (e.g., the processor 120, the first communication processor 212, or the second communication processor 214).
