This application is based on and claims priority under 35 U.S.C. 119 to Korean Patent Application No. 10-2019-0095693, filed on Aug. 6, 2019, in the Korean Intellectual Property Office, the disclosure of which is herein incorporated by reference in its entirety.
Various embodiments of the disclosure relate to an electronic device including a plurality of antenna modules.
To provide a stable quality of service over a commercial wireless communication network, an electronic device needs to meet a high gain and broad beam coverage of antenna modules. A next-generation mobile communication service (e.g., 5G communication) with a frequency band of a few tens of GHz (e.g., a frequency band ranging from 20 GHz to 300 GHz and a frequency wavelength ranging about 1 mm to about 10 mm) implements easy connection (e.g., wireless linkage) with nearby electronic devices and enhanced energy efficiency, thereby providing enhanced connection expandability and quicker and more stable quality of wireless communication networks to users.
Recently, wireless gigabit (WiGig), as an ultra-high rate short-range wireless communication standard, is under development. WiGig is technology of providing 10 times higher, or more, transmission speed as compared with conventional Wi-Fi in the Wi-Fi band (2.4/5 GHz) and 60 GHz band and is optimized for inter-device short-range transmission for digital video services.
Antenna modules are optimized for their operation properties by various simulations and may then be manufactured. In practice, however, the operation properties of an antenna module may be distorted when the antenna module is mounted on an electronic device despite optimization. In other words, the operation properties of the antenna module may be varied depending on the mounting environment of the antenna module or the specifications of the electronic device.
Since the frequency wavelength of the antenna module used for 5G communication (or mmWave communication) merely ranges from about 1 mm to about 10 mm, the radiation performance of the antenna module may be significantly distorted depending on the installation environment due to its high straightness and directivity. For example, when an antenna module for mmWave communication is equipped in an electronic device, the performance of the antenna module may be lowered due to interference by the structures around the electronic device or the user's body. A plurality of antenna modules may be provided in an electronic device to support 5G communication. In this case, propagation loss may be caused by interference between the beams radiated from adjacent antenna modules, thus resulting in deterioration of radiation performance.
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.
According to various embodiments, there may be provided a plurality of antenna modules capable of securing a stable radiation performance in a mmWave frequency band and an electronic device including the same.
According to various embodiments, there may be provided a plurality of antenna modules capable of providing a stable wireless communication function by preventing distortion of radiation performance due to interference by beams from adjacent antenna modules and an electronic device including the same.

The first CP 212 may establish a communication channel of a band that is to be used for wireless communication with the first cellular network 292 or may support legacy network communication via the established communication channel. According to an embodiment, the first cellular network may be a legacy network that includes second generation (2G), third generation (3G), fourth generation (4G), or long-term evolution (LTE) networks. The second CP 214 may establish a communication channel corresponding to a designated band (e.g., from about 6 GHz to about 60 GHz) among bands that are to be used for wireless communication with the second cellular network 294 or may support fifth generation (5G) network communication via the established communication channel. According to an embodiment, the second cellular network 294 may be a 5G network defined by 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 less) among the bands that are to be used for wireless communication with the second cellular network 294 or may support fifth generation (5G) network communication via the established communication channel.

According to an embodiment, the first CP 212 or the second CP 214, along with the processor 120, an assistance processor 123, or communication module 190, may be formed in a single chip or single package.
Upon transmission, the first RFIC 222 may convert a baseband signal generated by the first CP 212 into a radio frequency (RF) signal with a frequency ranging from about 700 MHz to about 3 GHz which is used by the first cellular network 292 (e.g., a legacy network). Upon receipt, the RF signal may be obtained from the first cellular network 292 (e.g., a legacy network) through an antenna (e.g., the first antenna module 242) and be pre-processed via an RFFE (e.g., the first RFFE 232). The first RFIC 222 may convert the pre-processed RF signal into a baseband signal that may be processed by the first CP 212.
Upon transmission, the second RFIC 224 may convert the baseband signal generated by the first CP 212 or the second CP 214 into a Sub6-band (e.g., about 6 GHz or less) RF signal (hereinafter, “5G Sub6 RF signal”) that is used by the second cellular network 294 (e.g., a 5G network). Upon receipt, the 5G Sub6 RF signal may be obtained from the second cellular network 294 (e.g., a 5G network) through an antenna (e.g., the second antenna module 244) and be pre-processed via an RFFE (e.g., the second RFFE 234). The second RFIC 224 may convert the pre-processed 5G Sub6 RF signal into a baseband signal that may be processed by a corresponding processor 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 a 5G Above6 band (e.g., from about 6 GHz to about 60 GHz) RF signal (hereinafter, “5G Above6 RF signal”) that is to be used by the second cellular network 294 (e.g., a 5G network). Upon receipt, 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 be pre-processed via the third RFFE 236. The third RFIC 226 may convert the pre-processed 5G Above6 RF signal into a baseband signal that may be processed by the second CP 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 the fourth RFIC 228 separately from, or as at least part of, the third RFIC 226. In this case, the fourth RFIC 228 may convert the baseband signal generated by the second CP 214 into an intermediate frequency band (e.g., from about 9 GHz to about 11 GHz) RF signal (hereinafter, “IF signal”) and transfer the IF signal to the third RFIC 226. The third RFIC 226 may convert the IF signal into a 5G Above6 RF signal. Upon receipt, 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 be converted into an IF signal by the third RFIC 226. The fourth RFIC 228 may convert the IF signal into a baseband signal that may 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 part of a single chip or single package. According to an embodiment, the first RFFE 232 and the second RFFE 234 may be implemented as at least part of a single chip or 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 be combined with another antenna module to process multi-band RF signals.
According to an embodiment, the third RFIC 226 and the antenna 248 may be disposed on the same substrate to form the third antenna module 246. For example, the wireless communication module 192 or the processor 120 may be disposed on a first substrate (e.g., a main painted circuit board (PCB)). In this case, the third RFIC 226 and the antenna 248, respectively, may be disposed on one area (e.g., the bottom) and another (e.g., the top) of a second substrate (e.g., a sub PCB) which is provided separately from the first substrate, forming the third antenna module 246. Placing the third RFIC 226 and the antenna 248 on the same substrate may shorten the length of the transmission line therebetween. This may reduce a loss (e.g., attenuation) of a high-frequency band (e.g., from about 6 GHz to about 60 GHz) signal used for 5G network communication due to the transmission line. Thus, the electronic device 101 may enhance the communication quality 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 which includes a plurality of antenna elements available for beamforming. In this case, the third RFIC 226 may include a plurality of phase shifters 238 corresponding to the plurality of antenna elements, as part of the third RFFE 236. Upon transmission, the plurality of phase shifters 238 may change the phase of the 5G Above6 RF signal which is to be transmitted to the outside (e.g., a 5G network base station) of the electronic device 101 via their respective corresponding antenna elements. Upon receipt, the plurality of phase shifters 238 may change the phase of the 5G Above6 RF signal received from the outside to the same or substantially the same phase via their respective corresponding antenna elements. This enables transmission or reception via beamforming between the electronic device 101 and the outside.
The second cellular network 294 (e.g., a 5G network) may be operated independently (e.g., as standalone (SA)) from, or in connection (e.g., as non-standalone (NSA)) with the first cellular network 292 (e.g., a legacy network). For example, the 5G network may include access networks (e.g., 5G access networks (RANs)) but lack any core network (e.g., a next-generation core (NGC)). In this case, the electronic device 101, after accessing a 5G network access network, may access an external network (e.g., the Internet) under the control of the core network (e.g., the evolved packet core (EPC)) of the legacy network. Protocol information (e.g., LTE protocol information) for communication with the legacy network or protocol information (e.g., New Radio (NR) protocol information) for communication with the 5G network may be stored in the memory 130 and be accessed by other components (e.g., the processor 120, the first CP 212, or the second CP 214).
