The disclosure was made by or on behalf of the below listed parties to a joint research agreement. The joint research agreement was in effect on or before the date the disclosure was made and the disclosure was made as a result of activities undertaken within the scope of the joint research agreement. The parties to the joint research agreement are 1) SAMSUNG ELECTRONICS CO., LTD. and 2) INDUSTRY-ACADEMIC COOPERATION FOUNDATION, YONSEI UNIVERSITY
The disclosure relates to an antenna device that provides a wireless communication function and an electronic device including the antenna device.
In order to provide a service of stabilized quality in a commercialized wireless communication network, a high gain and a wide radiation area (beam coverage) of an antenna device should be satisfied. Next generation mobile communication services (e.g., 5th generation (5G) communication) having a frequency band of several tens of gigahertz (GHz) or more (e.g., a frequency band in the range of 30 to 300 GHz and a resonant frequency wavelength in the range of approximately 1 to 10 mm) are capable of providing a wireless communication network improved in connection scalability to electronic devices and providing faster and more stable communication quality to users by implementing improved ease of connection (e.g., wireless connectivity) with nearby electronic devices and improved energy efficiency.
The above information is presented as background information only to assist with an understanding of the disclosure. No determination has been made, and no assertion is made, as to whether any of the above might be applicable as prior art with regard to the disclosure.
An antenna device used for wireless communication may be manufactured after optimizing the operation characteristic of the antenna device through various simulations in the process of developing the antenna device. However, even if the operational characteristics of the antenna device are optimized, the operational characteristics may be distorted when the antenna device is mounted on the electronic device. In other words, the operational characteristics of the antenna device may be variously changed depending on a specification of the electronic device or a mounting environment of the manufactured antenna device.
Since an antenna device used for (5th generation) 5G communication (or millimeter wave (mmWave) communication) has a resonant frequency wavelength of only about 1 to 10 mm, the rectilinearity and directivity are high, so that the radiation performance of the antenna device may be significantly distorted depending on the installation environment thereof. For example, when a manufactured mmWave communication antenna device is mounted on an electronic device or the like, the performance of the antenna device may be deteriorated due to interference with a peripheral structure or the like of the electronic device or a part of the user's body.
Accordingly, in the case where an antenna device is mounted on an electronic device but fails to exhibit optimized operational characteristics, it may take considerable time and expense to develop and manufacture the antenna device from the initial simulation stage to the practical production of the electronic device including, for example, re-development of the antenna.
According to some embodiments, control of the antenna beam radiation range of the antenna device (steering range control) may be performed using a processor and a communication module mounted within an electronic device, but it is merely one-dimensional control. In addition, it may be difficult to exhibit optimized operational characteristics of the antenna device since the material of the electronic device, for example, the design of a bezel made of a metal material, is not considered.
Aspects of the disclosure are to address at least the above-mentioned problems and/or disadvantages and to provide at least the advantages described below. Accordingly, an aspect of the disclosure is to provide an antenna structure that is capable of preventing the distortion of radiation performance due to the installation environment thereof and interference with surroundings thereby providing a stable wireless communication function and an electronic device including the antenna structure.
Another aspect of the disclosure is to provide an antenna structure that is capable of securing stable radiation performance in the millimeter wave (mmWave) frequency band, and an electronic device including the antenna structure.
Additional aspects will be set forth in part in the description which follows and, in part, will be apparent from the description, or may be learned by practice of the presented embodiments.
In accordance with an aspect of the disclosure, an electronic device is provided. The electronic device includes a communication module and an antenna structure electrically connected to the communication module. The antenna structure may include a conductive substrate including a first area and a second area adjacent to the first area, a plurality of first slits formed in the first area of the conductive substrate parallel to each other with a first predetermined interval therebetween in a predetermined direction, and a plurality of second slits formed in the second area of the conductive substrate at a position corresponding to an inter-slit area between at least some slits among the plurality of first slits. The plurality of second slits may be disposed parallel to each other at a second predetermined interval therebetween in the predetermined direction, and the plurality of second slits may be configured to extend to a portion of the inter-slit area.
In accordance with another aspect of the disclosure, an electronic device is provided. The electronic device includes a communication module, and an antenna structure electrically connected to the communication module. The antenna structure may include a conductive substrate including a first area and a second area adjacent to the first area, a plurality of slits formed in the first area of the conductive substrate parallel to each other with a first predetermined interval therebetween in a predetermined direction; and one or more slits formed in the second area of the conductive substrate at a position corresponding to an inter-slit area between at least some slits among the plurality of first slits. The one or more slits may be disposed parallel to each other in the predetermined direction, and the plurality of second slits may be configured to extend to a portion of the inter-slit area.
In accordance with another aspect of the disclosure, an electronic device is provided. The electronic device includes a housing having a space formed therein to accommodate at least one electronic component therein, and at least one antenna structure disposed in at least a part of the housing. The at least one antenna structure may include a plate that surrounds an inner space of the electronic device, the plate having a first face facing an outside of the electronic device, at least one of a first extension integrally extending from the plate and having a second face, at least a portion of which is oriented in a direction different from a direction in which the first face is oriented, or a second extension integrally extending from the plate and having a third face, at least a portion of which is oriented in a direction different from the direction in which the first face is oriented, and a plurality of slits formed in at least a part of the plate and at least a part of the first extension or in at least a part of the plate and at least a part of the second extension parallel to each other with a predetermined interval therebetween.
According to various embodiments, a plurality of conductive lines may be disposed on the rear face of the conductive substrate having the plurality of slits formed therein.
According to various embodiments disclosed herein, it is possible to secure a stable radiation performance in an antenna structure and an electronic device including the antenna structure by setting the antenna structure located in at least a part of the housing as a millimeter wave communication antenna. For example, by controlling the radiation range of antenna beams using a plurality of slits separately disposed in at least two areas of the antenna structure, it is possible to prevent a radiation performance from being distorted due to interference by a peripheral structure of the electronic device or a part of the user's body.
In accordance with another aspect of the disclosure, an antenna device and/or an electronic device are provided. The antenna device and/or the electronic device include the antenna device according to various embodiments of the disclosure, since a plurality of conductive lines are disposed adjacent to each other on the rear face of the conductive substrate in which the plurality of slits are formed, a resonant frequency can be easily adjusted.

The first CP 212 may establish a communication channel of a band to be used for wireless communication with the first cellular network 292, and may support legacy network communication through the established communication channel According to various embodiments, the first cellular network may be a legacy network including a 2nd generation (2G), 3rd generation (3G), 4th generation (4G), or long-term evolution (LTE) network. The second CP 214 may establish a communication channel corresponding to a designated band (e.g., about 6 GHz to about 60 GHz) of the band to be used for wireless communication with the second cellular network 294, and may support 5G network communication through the established communication channel According to various embodiments, the second cellular network 294 may be a 5G network as defined in the 3rd generation partnership project (3GPP). Additionally, according to an embodiment, the first CP 212 or the second CP 214 may establish a communication channel corresponding to another designated band (e.g., about 6 GHz or lower) in the band to be used for wireless communication with the second communication network 294, and may support 5G network communication through the established communication channel According to an embodiment, the first CP 212 and the second CP 214 may be implemented in a single chip or in a single package. According to various embodiments, the first CP 212 or the second CP 214 may be formed in a single chip or a single package with the processor 120, an auxiliary processor 123, or a communication module 190.
During transmission, the first RFIC 222 may convert a baseband signal generated by the first CP 212 to a radio frequency (RF) signal of about 700 MHz to about 3 GHz used in the first cellular network 292 (e.g., a legacy network). During reception, an RF signal may be acquired from the first cellular network S92 (e.g., the legacy network) through an antenna (e.g., the first antenna module 242), and may be pre-processed through an RFFE (e.g., the first RFFE 232). The first RFIC 222 may convert the pre-processed RF signal to a baseband signal for processing by the first CP 212.
During transmission, the second RFIC 224 may convert the baseband signal generated by the first CP 212 or the second CP 214 into an RF signal in a Sub6 band (e.g., about 6 GHz or lower) (hereinafter, referred to as a 5G sub6 RF signal) used in the second cellular network S94 (e.g., a 5G network). During reception, the 5G Sub6 RF signal is acquired from the second cellular network 294 (e.g., a 5G network) through an antenna (e.g., the second antenna module 244a), and may be pre-processed through an RFFE (e.g., the second antenna module 244). The second RFIC 224 may convert the pre-processed 5G Sub6 RF signal into a baseband signal to be processed by a corresponding one of the first CP 212 and the second CP 214.
The third RFIC 226 may convert the baseband signal generated by the second CP 214 into an RF signal (hereinafter, referred to as a “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., a 5G network). During reception, the 5G Above6 RF signal may be obtained from the second cellular network 294 (e.g., a 5G network) through an antenna (e.g., the antenna 248), and may be pre-processed through the third RFFE 236. The third RFIC 226 may convert the pre-processed 5G Above6 RF signal into a baseband signal so that the baseband signal can be processed by the second CP 214. According to an embodiment, the third RFFE 236 may be formed as a part of the third RFIC 226.
According to an embodiment, the electronic device 101 may include a fourth RFIC 228, separately from or as at least a part of the third RFIC 226. In this case, the fourth RFIC 228 may convert a baseband signal generated by the second CP 214 into an RF signal (hereinafter referred to as an “IF signal”) in an intermediate frequency band (e.g., about 9 GHz to about 11 GHz) and may then deliver the IF signal to the third RFIC 226. The third RFIC 226 may convert the IF signal into a 5G Above6 RF signal. During reception, the 5G Above6 RF signal may be received from the second cellular network 294 (e.g., a 5G network) through an antenna (e.g., the antenna 248), and may be converted into an 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 can be processed by the second CP 214.
According to an embodiment, the first RFIC 222 and the second RFIC 224 may be implemented as at least a part 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 part of a single chip or a single package. According to an embodiment, at least one of the first antenna module 242 and the second antenna module 244 may be omitted or combined with other antenna modules so as to process RF signals of a plurality of corresponding bands.
According to an embodiment, the third RFIC 226 and the antenna 248 may be placed on the same substrate so as to form a third antenna module 246. For example, the wireless communication module 192 or the processor 120 may be placed on a first substrate (e.g., a main PCB). In such a case, the third RFIC 226 may be disposed on a partial area (e.g., a lower face) of a second substrate (e.g., a sub-PCB) separate from the first substrate, and the antenna 248 may be disposed on another partial area (e.g., an upper face) and some areas, thereby forming the antenna module 246. By disposing the third RFIC 226 and the antenna 248 on the same substrate, it is possible to reduce the length of the transmission line therebetween. Through this, it is possible to reduce the loss (e.g., attenuation) of a signal in a high frequency band (e.g., about 6 GHz to about 60 GHz) used for, for example, 5G network communication by the transmission line. As a result, the electronic device 101 is able to improve the quality or speed of communication with the second cellular network 294 (e.g., a 5G network).
According to an embodiment, the antenna 248 may be formed as an antenna array that includes a plurality of antenna elements that can 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. During transmission, each of the plurality of phase shifters 38 may convert the phase of a 5G Above6 RF signal to be transmitted to the outside of the electronic device (e.g., the base station of a 5G network) through the corresponding antenna element. During reception, each of the plurality of phase shifters 238 may convert the phase of the 5G Above6 RF signal received from the outside into the same or substantially the same phase through the 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., a 5G network) may be operated independently from the first cellular network 292 (e.g., a legacy network) (e.g., stand-alone (SA)), or may be operated in the state of being connected to the first cellular network 292 (non-stand alone (NSA)). For example, a 5G network may have only an access network (e.g., a 5G radio access network (RAN) or a next generation RAN (NG RAN)), and a core network (e.g., a next generation core (NGC)) may not exist in the 5G network. In this case, after accessing the access network of the 5G network, the electronic device 101 may access the external network (e.g., the Internet) under the control of the core network (e.g., an evolved packed core (EPC)) of a legacy network. Protocol information for communication with a legacy network (e.g., LTE protocol information) or protocol information for communication with a 5G network (e.g., new radio (NR) protocol information) is stored in the memory 230, and may be accessed by another component (e.g., the processor 120, the first CP 212, or the second CP 214).
