In one embodiment, the auxiliary processor (123) (e.g., an image signal processor or a communication processor) may be implemented as a part of another functionally related component (e.g., a camera module (180) or a communication module (190)). In one embodiment, the auxiliary processor (123) (e.g., a neural network processing unit) may include a hardware structure specialized for processing artificial intelligence models.

[0026] The input module (150) can receive commands or data to be used in a component of the electronic device (101) (e.g., a processor (120)) from an external source (e.g., a user) of the electronic device (101). The input module (150) can include, for example, a microphone, a mouse, a keyboard, a key (e.g., a button), or a digital pen (e.g., a stylus pen).

[0027] The audio output module (155) can output audio signals to the outside of the electronic device (101). The audio output module (155) can include, for example, a speaker or a receiver. The speaker can be used for general purposes, such as multimedia playback or recording playback. The receiver can be used to receive incoming calls. In one embodiment, the receiver can be implemented separately from the speaker or as part of the speaker.

The display module (160) may include, for example, a display, a holographic device, or a projector and a control circuit for controlling the device. In one embodiment, the display module (160) may include a touch sensor configured to detect a touch, or a pressure sensor configured to measure the intensity of a force generated by the touch.

[0029] The audio module (170) can convert sound into an electrical signal, or vice versa, convert an electrical signal into sound. According to one embodiment, the audio module (170) can acquire sound through the input module (150), output sound through the sound output module (155), or an external electronic device (e.g., electronic device (102)) (e.g., speaker or headphone) directly or wirelessly connected to the electronic device (101).

[0030] The sensor module (176) can detect the operating status (e.g., power or temperature) of the electronic device (101) or the external environmental status (e.g., user status) and generate an electrical signal or data value corresponding to the detected status. According to one embodiment, the sensor module (176) can include, for example, a gesture sensor, a gyro sensor, a barometric pressure sensor, a magnetic sensor, an acceleration sensor, a grip sensor, a proximity sensor, a color sensor, an IR (infrared) sensor, a biometric sensor, a temperature sensor, a humidity sensor, or an illuminance sensor.

[0031] The interface (177) may support one or more designated protocols that may be used to directly or wirelessly connect the electronic device (101) to an external electronic device (e.g., the electronic device (102)). In one embodiment, the interface (177) may include, for example, a high definition multimedia interface (HDMI), a universal serial bus (USB) interface, an SD card interface, or an audio interface.

[0032] The connection terminal (178) may include a connector through which the electronic device (101) may be physically connected to an external electronic device (e.g., electronic device (102)). According to one embodiment, the connection terminal (178) may include, for example, an HDMI connector, a USB connector, an SD card connector, or an audio connector (e.g., a headphone connector).

[0035] The power management module (188) can manage the power supplied to the electronic device (101). According to one embodiment, the power management module (188) can be implemented as, for example, at least a part of a power management integrated circuit (PMIC).

[0036] A battery (189) may power at least one component of the electronic device (101). In one embodiment, the battery (189) may include, for example, a non-rechargeable primary battery, a rechargeable secondary battery, or a fuel cell.

[0037] The communication module (190) may support the establishment of a direct (e.g., wired) communication channel or a wireless communication channel between the electronic device (101) and an external electronic device (e.g., electronic device (102), electronic device (104), or server (108)), and the performance of communication through the established communication channel. The communication module (190) may operate independently from the processor (120) (e.g., application processor) and may include one or more communication processors that support direct (e.g., wired) communication or wireless communication. According to one 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 module). Among these communication modules, the corresponding communication module can communicate with an external electronic device (104) via a first network (198) (e.g., a short-range communication network such as Bluetooth, wireless fidelity (WiFi) direct, or infrared data association (IrDA)) or a second network (199) (e.g., a long-range communication network such as a legacy cellular network, a 5G network, a next-generation communication network, the Internet, or a computer network (e.g., a LAN or WAN)). These various types of communication modules can be integrated into a single component (e.g., a single chip) or implemented as multiple separate components (e.g., multiple chips). The wireless communication module (192) can verify or authenticate the electronic device (101) within a communication network such as the first network (198) or the second network (199) by using subscriber information (e.g., an international mobile subscriber identity (IMSI)) stored in the subscriber identification module (196).

[0038] The wireless communication module (192) can support 5G networks and next-generation communication technologies following the 4G network, such as NR access technology (new radio access technology). The NR access technology can support high-speed transmission of high-capacity data (eMBB (enhanced mobile broadband)), minimization of terminal power and connection of multiple terminals (mMTC (massive machine type communications)), or high reliability and low latency (URLLC (ultra-reliable and low-latency communications)). The wireless communication module (192) can support, for example, a high-frequency band (e.g., mmWave band) to achieve a high data transmission rate. The wireless communication module (192) can support various technologies for securing performance in a high-frequency band, such as beamforming, massive multiple-input and multiple-output (MIMO), full dimensional MIMO (FD-MIMO), array antenna, analog beam-forming, or large scale antenna. The wireless communication module (192) can support various requirements specified in the electronic device (101), an external electronic device (e.g., the electronic device (104)), or a network system (e.g., the second network (199)). According to one embodiment, the wireless communication module (192) can support a peak data rate (e.g., 20 Gbps or more) for eMBB realization, a loss coverage (e.g., 164 dB or less) for mMTC realization, or a U-plane latency (e.g., 0.5 ms or less for downlink (DL) and uplink (UL), or 1 ms or less for round trip) for URLLC realization.

[0039] The antenna module (197) can transmit or receive signals or power to or from an external device (e.g., an external electronic device). In one embodiment, the antenna module (197) may include an antenna including a radiator formed of a conductor or a conductive pattern formed on a substrate (e.g., a PCB). In one embodiment, the antenna module (197) may include a plurality of antennas (e.g., an array antenna). In this case, at least one antenna suitable for a communication method used in a communication network, such as the first network (198) or the second network (199), may be selected from the plurality of antennas, for example, by the communication module (190). A signal or power may be transmitted or received between the communication module (190) and an external electronic device via the selected at least one antenna. In some embodiments, in addition to the radiator, another component (e.g., a radio frequency integrated circuit (RFIC)) may be additionally formed as a part of the antenna module (197).

[0040] In one embodiment, the antenna module (197) may form a mmWave antenna module. In one embodiment, the mmWave antenna module may include a printed circuit board, an RFIC disposed on or adjacent a first side (e.g., a bottom side) of the printed circuit board and capable of supporting a designated high frequency band (e.g., a mmWave band), and a plurality of antennas (e.g., an array antenna) disposed on or adjacent a second side (e.g., a top side or a side side) of the printed circuit board and capable of transmitting or receiving signals in the designated high frequency band.

[0041] At least some of the above components can be interconnected and exchange signals (e.g., commands or data) with each other via a communication method between peripheral devices (e.g., a bus, GPIO (general purpose input and output), SPI (serial peripheral interface), or MIPI (mobile industry processor interface)).

[0042] According to one embodiment, commands or data may be transmitted or received between the electronic device (101) and an external electronic device (104) via a server (108) connected to a second network (199). Each of the external electronic devices (102 or 104) may be the same or a different type of device as the electronic device (101). According to one embodiment, all or part of the operations executed in the electronic device (101) may be executed in one or more of the external electronic devices (102, 104, or 108). For example, when the electronic device (101) is to perform a certain function or service automatically or in response to a request from a user or another device, the electronic device (101) may, instead of or in addition to executing the function or service itself, request one or more external electronic devices to perform the function or at least part of the service. One or more external electronic devices that receive the request may execute at least a portion of the requested function or service, or an additional function or service related to the request, and transmit the result of the execution to the electronic device (101). The electronic device (101) may process the result as is or additionally and provide it as at least a portion of a response to the request. For this purpose, cloud computing, distributed computing, mobile edge computing (MEC), or client-server computing technology may be used, for example. The electronic device (101) may provide an ultra-low latency service by using distributed computing or mobile edge computing, for example. In another embodiment, the external electronic device (104) may include an Internet of Things (IoT) device. The server (108) may be an intelligent server utilizing machine learning and / or a neural network. According to one embodiment, the external electronic device (104) or the server (108) may be included in the second network (199).The electronic device (101) can be applied to intelligent services (e.g., smart home, smart city, smart car, or healthcare) based on 5G communication technology and IoT-related technology.

[0043] According to an exemplary embodiment, an electronic device (101) may perform a multiple-input and multiple-output (MIMO) operation using multiple antennas. The electronic device (101) may transmit a signal on a first frequency band to a base station or receive a signal on the first frequency band from the base station using multiple antennas. Through MIMO, a data transmission rate may be improved.

[0044] As electronic devices (101) become smaller, the space for arranging multiple antenna radiators within the electronic device (101) may be limited. As antenna radiators are arranged within a limited space, different antennas may be adjacent to each other. When antennas are arranged closely together, the peak direction and shape of a radiation pattern formed by one antenna may be substantially the same or similar to the peak direction and shape of a radiation pattern formed by another antenna. When the peak directions and shapes of the radiation patterns are substantially the same or similar, the envelope correlation coefficient (ECC) between the radiation patterns increases, making it difficult for different antennas to transmit and / or receive various signals in a MIMO environment, and the communication performance (e.g., throughput) of the electronic device (101) may deteriorate.

[0045] An electronic device (101) according to an exemplary embodiment may be configured to adjust the phase of a signal to reduce ECC between radiation patterns. For example, while a first signal on a first frequency band is transmitted and / or received through a first antenna radiator (e.g., the first antenna radiator (241) of FIG. 2A), the electronic device (101) may perform a MIMO operation by transmitting and / or receiving a second signal on a second frequency band that at least partially overlaps with the first frequency band using a second antenna radiator (e.g., the second antenna radiator (242) of FIG. 2A) and a third antenna radiator (e.g., the third antenna radiator (243) of FIG. 2A) as a single antenna radiator. In order to transmit and / or receive a second signal on a frequency band that at least partially overlaps with a first signal transmitted and / or received through the first antenna radiator (241), the second antenna radiator (242) and the third antenna radiator (243) may be electrically connected through a distribution circuit (e.g., the distribution circuit (250) of FIG. 2A). Through the distribution circuit (250), the second signal may be transmitted to the second antenna radiator (242) and the third antenna radiator (243).

[0046] An electronic device (101) according to an exemplary embodiment may be configured to form a difference between a first phase of a second signal provided to a second antenna radiator (242) and a second phase of a second signal provided to a third antenna radiator (243). For example, the electronic device (101) may include a phase control unit (260) for forming a difference between the first phase and the second phase. The phase control unit (260) may include, but is not limited to, a component such as a phase shifter (e.g., the first phase shifter (261) or the second phase shifter (262) of FIG. 4B) or a matching circuit (e.g., the first matching circuit (263) or the second matching circuit (264) of FIG. 4C). For example, the difference between the first phase and the second phase may be formed by controlling the length or width of a transmission line for a signal provided to the antenna radiator. The peak direction of the second radiation pattern formed from the second antenna radiator (242) and the third antenna radiator (243) can be adjusted through the difference between the first phase of the second signal provided to the second antenna radiator (242) and the second phase of the second signal provided to the third antenna radiator (243). Since the peak direction of the second radiation pattern is formed differently from the peak direction of the first radiation pattern formed from the first antenna radiator (241), the ECC between the first radiation pattern and the second radiation pattern can be reduced.

[0047] Below, an electronic device (101) according to an exemplary embodiment is described.

[0048] FIGS. 2A, 2B, and 2C are block diagrams of an electronic device according to an exemplary embodiment.

For example, each of the RFFE circuits (230) may include components such as, but not limited to, a coupler, a power amplifier (PA), a low noise amplifier (LNA), a switch circuit, and / or a duplexer.

[0054] According to an exemplary embodiment, the RFFE circuits (230) may be configured to communicate with an external electronic device using a signal on a designated frequency band. For example, each of the plurality of antenna radiators (240) may be used to transmit and / or receive a signal on a designated frequency band. For example, the plurality of antenna radiators (240) may include a feed point to which a feed signal provided from the RF transceiver (220) is provided and / or a ground point electrically connected to the ground of the electronic device (101). The plurality of antenna radiators (240) are physical components for radiating or receiving electromagnetic waves, and the shape and characteristics of the antenna (e.g., frequency characteristics of the antenna) may be determined by each of the antenna radiators (240). Within FIG. 2A, the antenna radiators (240) are illustrated as including a first antenna radiator (241), a second antenna radiator (242), and a third antenna radiator (242), but the embodiment is not limited thereto.

[0056] According to an exemplary embodiment, the first RFFE circuit (231) may be electrically connected to the first antenna radiator (241). The first RFFE circuit (231) may be used to transmit or receive a first signal on a first frequency band. For example, a first signal provided from an RF transceiver (220) may be provided to the first antenna radiator (241) through the first RFFE circuit (231) and then radiated to the outside of the electronic device (101) through the first antenna radiator (241).

[0058] According to an exemplary embodiment, the third RFFE circuit (233) may be used to transmit or receive a third signal on a third frequency band different from the first frequency band. The third RFFE circuit (233) may be electrically connected to a third antenna radiator (243). The third signal provided from the RF transceiver (220) may be provided to the third antenna radiator (243) through the third RFFE circuit (233) and then radiated to the outside of the electronic device (101) through the third antenna radiator (243). For example, the first frequency band may include a low band and a high band, the second frequency band may include a high band and an ultra-high band, and the third frequency band may include a mid band and a high band. For example, the first frequency band may include a band of about 1 GHz or more, and the third frequency band may include a band of about 2 GHz or about 5 GHz, excluding the first frequency band. However, the above-described frequency bands are merely exemplary, and the embodiments are not limited thereto. According to an exemplary embodiment, an antenna including a third antenna radiator (243) may be provided. According to one embodiment, the third antenna radiator (243) may be configured to transmit and / or receive a signal in the third frequency band.

[0059] According to an exemplary embodiment, the distribution circuit (250) may be a three-port passive component. For example, the three ports of the distribution circuit (250) may each provide an electrical transmission line having a characteristic impedance of 50 ohms. A signal (e.g., a transmission signal) input through the first port (251) may be distributed to have equal power and output to the second port (252) and the third port (253), respectively. Signals (e.g., a reception signal) input to the second port (252) and the third port (253) may be combined into a single signal and output to the first port (251). The distribution circuit (250) may be referred to as a power divider, a splitter, power branch circuitry, and / or a coupler.

[0060] According to an exemplary embodiment, the distribution circuit (250) may electrically connect the second RFFE circuit (232) to the second antenna radiator (242) and the third antenna radiator (243). For example, the first port (251) may be electrically connected to the second RFFE circuit (232), the second port (252) may be electrically connected to the second antenna radiator (242), and the third port (253) may be electrically connected to the third antenna radiator (243). A second signal provided from the second RFFE circuit (232) may be branched into a second signal provided to the second antenna radiator (242) and a second signal provided to the third antenna radiator (243) through the distribution circuit (250). For example, the electronic device (101) may include a first transmission line (P1) between a distribution circuit (250) and a second antenna radiator (242), a second transmission line (P2) between the distribution circuit (250) and a third antenna radiator (243), and a third transmission line (P3) extending from a third RFFE circuit (233) and connected to the second transmission line (P2). A second signal may be provided (or fed) to the second antenna radiator (242) along the first transmission line (P1). The second signal may be provided (or fed) to the third antenna radiator (243) along the second transmission line (P2). The second signal may be radiated to the outside through the second antenna radiator (242) and the third antenna radiator (243). According to an exemplary embodiment, an antenna may be provided that uses a second antenna radiator (242) and / or a third antenna radiator (243) as a radiator.

[0061] According to an exemplary embodiment, the electronic device (101) may include a phase adjuster (260) for causing a difference between a first phase of a second signal provided from a distribution circuit (250) to a second antenna radiator (242) and a second phase of a second signal provided from a distribution circuit (250) to a third antenna radiator (243). The phase adjuster (260) may be electrically connected to the second antenna radiator (242) and / or the third antenna radiator (243). For example, the phase adjuster (260) may include a phase shifter (e.g., the first phase shifter (261) or the second phase shifter (262) of FIG. 4b) or a matching circuit (e.g., the first matching circuit (263) or the second matching circuit (264) of FIG. 4c) configured to adjust the phase of a signal.

[0062] For example, the phase control unit (260) may include at least one of a first phase shifter (261) and / or a second phase shifter (262). The first phase shifter (261) may be disposed between the distribution circuit (250) and the second antenna radiator (242). For example, the first phase shifter (261) may be disposed on the first transmission line (P1). The second phase shifter (262) may be disposed between the distribution circuit (250) and the second antenna radiator (242). For example, the second phase shifter (262) may be disposed on the second transmission line (P2).

[0063] According to an exemplary embodiment, the first phase shifter (261) and / or the second phase shifter (262) may cause a difference between a first phase of a second signal transmitted to the second antenna radiator (242) and a second phase of a second signal transmitted to the third antenna radiator (243). The first phase and the second phase may be different from each other by the first phase shifter (261) and / or the second phase shifter (262). For example, the difference between the first phase and the second phase may be between about 0 degrees and 270 degrees. For example, for the high band, the difference between the first phase and the second phase may be about 45 degrees, but is not limited thereto.

[0064] According to an exemplary embodiment, the first phase shifter (261) and / or the second phase shifter (262) may include passive components (e.g., inductors and / or capacitors). The phase shifters (261, 262) may shift the phase of a signal output from the first phase shifter (261) and / or the second phase shifter (262) by delaying the phase of a signal input to the phase shifters (261, 262). For example, a second signal provided from the second RFFE circuit (232) to the power divider (250) may be branched by the power divider (250) into a second signal provided to the first transmission line (P1) and a second signal provided to the second transmission line (P2). The second signal provided to the second antenna radiator (242) can pass through the first phase shifter (261) arranged on the first transmission line (P1), and the second signal provided to the third antenna radiator (243) can pass through the second phase shifter (262) arranged on the second transmission line (P2). The second signal can have a first phase and / or a second phase shifted by the first phase shifter (261) and / or the second phase shifter (262). However, the present invention is not limited thereto. For example, the phase control unit (260) may include a matching circuit including at least one passive element. For example, a difference between the first phase and the second phase may be caused by the first length or the first width of the first transmission line (P1), and the second length or the second width of the second transmission line (P2).

[0065] According to an exemplary embodiment, when a second signal is radiated through the second antenna radiator (242) and the third antenna radiator (243), a peak direction of a radiation pattern may be determined based on a difference between a first phase and a second phase. The difference between the first phase and the second phase may affect a peak direction of a radiation pattern formed from the second antenna radiator (242) and the third antenna radiator (243) when the second signal is transmitted and / or received. At least one processor (210) may be configured to transmit and / or receive a second signal on a second frequency band through the second antenna radiator (242) and the third antenna radiator (243) while a first signal on a first frequency band is transmitted and / or received through the first antenna radiator (241) to perform a MIMO operation. A peak direction of a radiation pattern according to the second signal may be adjusted based on the difference between the first phase and the second phase. According to an exemplary embodiment, as the peak direction of the radiation pattern according to the second signal is adjusted, the ECC between the radiation pattern according to the second signal and the radiation pattern according to the first signal can be reduced. According to an exemplary embodiment, as the ECC is reduced, interference between the first signal and the second signal is reduced, so that the communication performance of the electronic device (101) can be improved.

[0066] As described above, the third antenna radiator (243) can operate as part of another antenna for transmitting and / or receiving a third signal on a third frequency band, independently of the second antenna radiator (242). According to an exemplary embodiment, the third antenna radiator (243), which can operate as part of another antenna, can be used together with the second antenna radiator (242) for transmitting and / or receiving a second signal. Since the third antenna radiator (243) is electrically connected to the third RFFE circuit (233) for transmitting and / or receiving the third signal, the second signal or the third signal may interfere with each other on a transmission line (e.g., the second transmission line (P2) and / or the third transmission line (P3)) connected to the third antenna radiator (243). The above interference may be a problem caused by using a third antenna radiator (243) for another antenna together with the second antenna radiator (242) to adjust the peak direction of the radiation pattern according to the second signal. By using the third antenna radiator (243) together with the second antenna radiator (242), the electronic device (101) may include a filtering circuit (270) to eliminate interference between the second signal and the third signal.

[0067] An electronic device (101) according to an exemplary embodiment may include a filtering circuit (270). The filtering circuit (270) may be electrically connected to a third antenna radiator (243). The filtering circuit (270) may be configured to transmit a second signal from a distribution circuit (250) to the third antenna radiator (243) or a third signal from a third RFFE circuit (233) to the third antenna radiator (243) depending on the operation of the electronic device (101). For example, when at least one processor (210) performs an operation of transmitting a second signal, the filtering circuit (270) can transmit the second signal provided through the second RFFE circuit (232) and the distribution circuit (250) to the third antenna radiator (243), and when at least one processor (210) performs an operation of transmitting a third signal, the filtering circuit (270) can transmit the third signal provided from the third RFFE circuit (233) to the third antenna radiator (243).

[0068] Referring to FIG. 2A, the filtering circuit (270) may include a diplexer (271). The diplexer (271) may be configured to separate a second signal on a second frequency band and a third signal on a third frequency band. The diplexer (271) may be positioned at a point where the second transmission line (P2) and the third transmission line (P3) are connected.

[0069] According to an exemplary embodiment, the diplexer (271) may be configured to transmit the second signal from the distribution circuit (250) to the third antenna radiator (243). For example, the second signal output from the third port (253) may be provided to the diplexer (271), transmitted to the third antenna radiator (243) through the diplexer (271), and then radiated. Since the diplexer (271) does not transmit the second signal to the third transmission line (P3), the second signal may not be transmitted to the third RFFE circuit (233).

[0070] According to an exemplary embodiment, the diplexer (271) may be configured to transmit a second signal from the third antenna radiator (243) to the distribution circuit (250). For example, the second signal received through the third antenna radiator (243) may be provided to the diplexer (271), transmitted to the distribution circuit (250) through the diplexer (271), and then transmitted to the second RFFE circuit (232). Since the diplexer (271) does not transmit the second signal to the third transmission line (P3), the second signal may not be transmitted to the third RFFE circuit (233).

[0071] According to an exemplary embodiment, the diplexer (271) may be configured to transmit a third signal from the third RFFE circuit (233) to the third antenna radiator (243). For example, the third signal output from the third RFFE circuit (233) may be provided to the diplexer (271) through the third transmission line (P3), transmitted to the third antenna radiator (243) through the diplexer (271), and then radiated. Since the diplexer (271) does not transmit the third signal to the distribution circuit (250), the third signal may not be transmitted to the second RFFE circuit (232).

[0072] According to an exemplary embodiment, the diplexer (271) may be configured to transmit a third signal from the third antenna radiator (243) to the third RFFE circuit (233). For example, the third signal received through the third antenna radiator (243) may be provided to the diplexer (271), transmitted to the third transmission line (P3) through the diplexer (271), and then transmitted to the third RFFE circuit (233) along the third transmission line (P3). Since the diplexer (271) does not transmit the third signal to the distribution circuit (250), the third signal may not be transmitted to the second RFFE circuit (232).

[0073] As described above, the second signal and the third signal are separated by the diplexer (271), so that they do not interfere with each other. In addition to the diplexer (271), the filtering circuit (270) may include a first band-pass filter (e.g., the first band-pass filter (272) of FIG. 2b) and / or a second band-pass filter (e.g., the second band-pass filter (273) of FIG. 2c).

[0074] Referring to FIG. 2B, the filtering circuit (270) may include a first band-pass filter (272). The first band-pass filter (272) may be placed on the second transmission line (P2) between the point where the second transmission line (P2) and the third transmission line (P3) are connected and the distribution circuit (250). The first band-pass filter (272) may be configured to pass a signal on a second frequency band.

[0075] According to an exemplary embodiment, the first band pass filter (272) may be configured to transmit a second signal from the distribution circuit (250) to the third antenna radiator (243). For example, the second signal output from the third port (253) may be provided to the first band pass filter (272), passed through the first band pass filter (272), transmitted to the third antenna radiator (243), and then radiated.

[0076] According to an exemplary embodiment, the first band pass filter (272) may be configured to transmit a second signal from the third antenna radiator (243) to the distribution circuit (250). For example, the second signal received through the third antenna radiator (243) may pass through the first band pass filter (272) to the distribution circuit (250) and then to the second RFFE circuit (232).

[0077] According to an exemplary embodiment, the first band pass filter (272) may be configured to filter a third signal from the third RFFE circuit (233). For example, when the third signal provided from the third RFFE circuit (233) to the third antenna radiator (243) is provided to the first band pass filter (272), the first band pass filter (272) may be configured to filter the third signal. By the first band pass filter (272) filtering the third signal so that it is not provided to the distribution circuit (250), the third signal may not be transmitted to the second RFFE circuit (232).

[0078] According to an exemplary embodiment, the first band pass filter (272) may be configured to filter a third signal from the third antenna radiator (243). For example, the third signal received through the third antenna radiator (243) may be provided to the third RFFE circuit (233) along the second transmission line (P2) and the third transmission line (P3). When the third signal is provided to the first band pass filter (272), the first band pass filter (272) may be configured to filter the third signal. Since the first band pass filter (272) filters the third signal so that it is not provided to the distribution circuit (250), the third signal may not be transmitted to the second RFFE circuit (232).

[0079] Referring to FIG. 2c, the filtering circuit (270) may include a second band-pass filter (273). The second band-pass filter (273) may be placed on the third transmission line (P3). The second band-pass filter (273) may be configured to pass a signal on a third frequency band.

[0080] According to an exemplary embodiment, the second band pass filter (273) may be configured to pass a third signal from the third RFFE circuit (233). For example, the third signal output from the third RFFE circuit (233) may pass through the second band pass filter (273) and be transmitted to the third antenna radiator (243).

[0081] According to an exemplary embodiment, the second band pass filter (273) may be configured to pass a third signal from the third antenna radiator (243). For example, the third signal received through the third antenna radiator (243) may be provided to the second band pass filter (273) along the second transmission line (P2) and the third transmission line (P3), and may be transmitted to the third RFFE circuit (233) through the second band pass filter (273).

[0082] According to an exemplary embodiment, the second band pass filter (273) may be configured to filter a second signal from the distribution circuit (250). For example, when the second signal provided from the distribution circuit (250) to the third antenna radiator (243) is provided to the second band pass filter (273) along the third transmission line (P3), the second band pass filter (273) may be configured to filter the second signal. By the second band pass filter (273) filtering the second signal, the second signal may not be transmitted to the third RFFE circuit (233).

[0083] Referring to FIGS. 2A, 2B, and 2C, the exemplary electronic device (101) may further include a grip sensor (290) for identifying a user's grip on the electronic device (101). At least one processor (210) may be configured to control the phase control unit (260) based on the identification of the grip. The operation is described below with reference to FIG. 6.

[0084] Figure 3 illustrates an electronic device according to an exemplary embodiment.

[0085] Referring to FIG. 3, an electronic device (101) according to an exemplary embodiment may include a housing (301) that defines an exterior of the electronic device (101). The housing (301) may include a peripheral part (310) and a supporting part (320). The peripheral part (310) may define a side exterior surface of the electronic device (101). The supporting part (320) may support components of the electronic device (101), such as a printed circuit board or a battery. In terms of supporting the components, the supporting part (320) may be referred to as a supporting member, a supporting plate, or a bracket.

[0086] According to an exemplary embodiment, the edge portion (310) may include a first conductive portion (311), a second conductive portion (312), and / or a third conductive portion (313). The first conductive portion (311), the second conductive portion (312), and / or the third conductive portion may define a portion of a side surface of the electronic device (101). The first conductive portion (311) (e.g., the first antenna radiator (241) of FIG. 2A), the second conductive portion (312) (e.g., the second antenna radiator (242) of FIG. 2A), and the third conductive portion (313) (e.g., the third antenna radiator (243) of FIG. 2A) may be physically separated from each other by non-conductive portions. For example, the non-conductive portions may include a first non-conductive portion (321), a second non-conductive portion (322), a third non-conductive portion (323), and / or a fourth non-conductive portion (324). The first non-conductive portion (321) may be formed on a +x-direction side surface of the edge portion (310). The second non-conductive portion (322) may be formed on a +y-direction side surface of the edge portion (310). The third non-conductive portion (323) may be formed on a +y-direction side surface of the edge portion (310) and may be spaced apart from the second non-conductive portion (322) in the -x direction. The fourth non-conductive portion (324) may be formed on a -x-direction side surface of the edge portion (310). According to an exemplary embodiment, the first conductive portion (311) may be formed between the first non-conductive portion (321) and the second non-conductive portion (322). The second conductive portion (312) may be formed between the second non-conductive portion (322) and the third non-conductive portion (323). The third conductive portion (313) may be formed between the third non-conductive portion (323) and the fourth non-conductive portion (324). The plurality of non-conductive portions formed between the plurality of conductive portions may serve as a dielectric to limit the electrical length of the conductive portion that operates as an antenna radiator.For example, the non-conductive portions may be in contact with an opening portion between the edge portion (310) and the support portion (320). For example, the opening portion may be filled with a non-conductive material (e.g., poly carbonate).

[0087] According to an exemplary embodiment, the first antenna radiator (e.g., the first antenna radiator (241) of FIG. 2A), the second antenna radiator (e.g., the second antenna radiator (242) of FIG. 2A), and / or the third antenna radiator (e.g., the third antenna radiator (243) of FIG. 2A) may be implemented as conductive portions forming at least a portion of the edge portion (310). For example, the first conductive portion (311) may operate as the first antenna radiator (241), the second conductive portion (312) may operate as the second antenna radiator (242), and / or the third conductive portion (313) may operate as the third antenna radiator (243). The first RFFE circuit (231) may feed a first signal on a first frequency band to the first feed point (F1) of the first conductive portion (311). The RF transceiver (220) can upconvert a baseband digital signal provided from at least one processor (210) into a first signal having a frequency in a first frequency band and convert it into an analog signal. The first signal can be provided to a first feed point (F1) of a first conductive portion (311) and radiated to the outside of the electronic device (101) through the first conductive portion (311). When the first signal is radiated, a radiation pattern according to the first signal can be formed.

[0088] According to an exemplary embodiment, while the first signal is radiated, a second signal may be radiated through the second conductive portion (312) and a second signal may be radiated through the third conductive portion (313). A signal on a first frequency band provided from the second RFFE circuit (232) may be input to a first port (e.g., the first port (251) of FIG. 2A) of a distribution circuit (e.g., the distribution circuit (250) of FIG. 2A). The signal may be branched into a second signal output to a second port (e.g., the second port (252) of FIG. 2A) of the distribution circuit (250) and a second signal output to a third port (253) of the distribution circuit (250). The second signal output to the second port (252) may be fed to a second feed point (F2) of the second conductive portion (312) along the first transmission line (P1). The second signal output to the third port (253) can be fed to the third feed point (F3) of the third conductive portion (313) along the second transmission line (P2). Among the second transmission lines (P2), the transmission line connected to the second feed point (F2) can be referred to as the second feed line (332), and among the third transmission lines (P3), the transmission line connected to the third feed point (F3) can be referred to as the third feed line (333).

[0089] According to an exemplary embodiment, the electronic device (101) may include a phase shifter (e.g., the phase shifter (260) of FIG. 2A). For example, the electronic device (101) may include at least one of a first phase shifter (261) and / or a second phase shifter (262). The first phase shifter (261) disposed on the first transmission line (P1) may shift the phase of a second signal provided to the second conductive portion (312), and the second phase shifter (262) disposed on the second transmission line (P2) may shift the phase of the second signal provided to the third conductive portion (313). As the phase of the second signal is shifted, a peak direction of a radiation pattern formed from the second conductive portion (312) and the third conductive portion (313) may have a peak direction based on the shifted phase of the second signal. In FIG. 3, as an example of the phase control unit (260), a first phase shifter (261) and a second phase shifter (262) are shown, but the phase shifters (261, 262) can be replaced with the matching circuits (263, 264) of FIG. 4c.

[0090] According to an exemplary embodiment, as illustrated in FIG. 3, the second conductive portion (312) may be disposed between a portion of the first conductive portion (311) and a portion of the third conductive portion (313). As the second conductive portion (312) is adjacent to the first conductive portion (311), a peak direction of a radiation pattern formed by feeding the second conductive portion (312) may be substantially the same as or similar to a peak direction of a radiation pattern formed by feeding the first conductive portion (311).

[0091] If the peak direction of the radiation pattern (e.g., the first radiation pattern) formed from the first conductive portion (311) and the peak direction of the radiation pattern (e.g., the second radiation pattern) formed from the second conductive portion (312) are substantially the same or similar, mutual interference between the first signal and the second signal may occur. The interference may cause deterioration of the communication performance of the electronic device (101) (e.g., reduction in throughput).

[0092] According to an exemplary embodiment, the peak direction of the second radiation pattern can be adjusted by shifting the phase of the second signal. For example, when the phase of the second signal is shifted by the phase control unit (260), the peak direction of the second radiation pattern can be formed differently from the peak direction of the first radiation pattern. As the peak direction of the second radiation pattern is changed, interference between the first signal and the second signal is reduced, thereby reducing deterioration of the communication performance of the electronic device (101).

[0093] According to an exemplary embodiment, the second conductive portion (312) and the third conductive portion (313) may operate as a single antenna on at least partially overlapping first and second frequency bands, but the electronic device (101) may include a filtering circuit (e.g., a filtering circuit (270) of FIG. 2A) for a third signal on a third frequency band, so that the third signal may be radiated to the outside of the electronic device (101) through the third conductive portion (313). In FIG. 3, a diplexer (271) is illustrated as an example of the filtering circuit (270), but the diplexer (271) may be replaced with a first band pass filter (272) of FIG. 2B or a second band pass filter (273) of FIG. 2C.

[0094] According to an exemplary embodiment, the third conductive portion (313) may operate solely as an antenna for a third signal on a third frequency band. In one embodiment, the third signal on the third frequency band provided from the third RFFE circuit (233) may be provided to the third feed point (F3) of the third conductive portion (313) and may be radiated to the outside of the electronic device (101) through the third conductive portion (313).

[0095] According to an exemplary embodiment, the filtering circuit (270) may be electrically connected to the third conductive portion (313). As described above, the filter circuit (270) may include at least one of a diplexer (e.g., the diplexer (271) of FIG. 2A), a first band pass filter (e.g., the first band pass filter (272) of FIG. 2B), or a second band pass filter (e.g., the second band pass filter (273) of FIG. 2C). The filtering circuit (270) may be operable such that the third conductive portion (313) may be used together with the second conductive portion (312) for the second signal, or the third conductive portion (313) may be used alone for the third signal. The electronic device (101) can transmit and / or receive signals of various frequency bands using the first conductive portion (311), the second conductive portion (312), and the third conductive portion (313).

[0096] In FIG. 3, the first antenna radiator (241), the second antenna radiator (242), and / or the third antenna radiator (243) are described as examples of being implemented as conductive portions of the edge portion (310), but embodiments of the present disclosure are not limited thereto. According to an exemplary embodiment, each of the first antenna radiator (241), the second antenna radiator (242), and / or the third antenna radiator (243) may be implemented as a patch antenna, a laser direct structuring (LDS) antenna, or a flexible printed circuit board (FPCB) antenna, and in this case, the peak direction of the second radiation pattern may be adjusted through phase shift.

[0097] FIG. 4A illustrates an electronic device and a radiation pattern according to an exemplary embodiment.

[0098] Referring to FIG. 4A, an electronic device (101) according to an exemplary embodiment may include a distribution circuit (e.g., distribution circuit (250) of FIG. 2A) and / or a phase control unit (e.g., phase control unit (260) of FIG. 2A), as described with reference to FIGS. 2A, 2B, 2C, and 3. A second signal provided from a second RFFE circuit (e.g., second RFFE circuit (232) of FIG. 2A) may be branched through the distribution circuit (250). The second signal may be provided to a second antenna radiator (242) and a third antenna radiator (243) through the distribution circuit (250). The phase control unit (260) can cause a difference between the first phase of the second signal transmitted to the second antenna radiator (242) and the second phase of the second signal transmitted to the third antenna radiator (243) by shifting the phase of the second signal. Based on the difference between the first phase and the second phase, the peak direction of the second radiation pattern (402) can be adjusted. According to an exemplary embodiment, by adjusting the peak direction of the second radiation pattern (402), the first radiation pattern (401) and the second radiation pattern (402) can be formed such that the peak of the first radiation pattern (401) faces a first direction (D1) and the peak of the second radiation pattern (402) faces a second direction (D2) different from the first direction (D1).

[0099] An electronic device (101) according to an exemplary embodiment can improve communication performance by adjusting a peak direction of a second radiation pattern (402) according to a second signal while a first signal is transmitted and / or received through a first antenna radiator (241). Referring to FIG. 4A, since the peak direction of the first radiation pattern (401) (e.g., the first direction (D1)) and the peak direction of the second radiation pattern (402) (e.g., the second direction (D2)) are formed differently, ECC between the first radiation pattern (401) and the second radiation pattern (402) can be reduced. An electronic device (101) according to an exemplary embodiment can reduce interference between a first signal transmitted and / or received through the first radiation pattern (401) and a second signal transmitted and / or received through the second radiation pattern (402). As the above interference is reduced, the electronic device (101) according to the exemplary embodiment can provide improved communication performance.

[0100] Embodiments of the electronic device (101) for shifting the phase of the second signal may vary. For example, the electronic device (101) may include a component such as a phase shifter (e.g., the first phase shifter (261) or the second phase shifter (262) of FIG. 4B) or a matching circuit (e.g., the first matching circuit (263) or the second matching circuit (264) of FIG. 4C). For example, the electronic device (101) may include a first transmission line (P1) and a second transmission line (P2) having different lengths or widths. For example, when the electronic device (101) includes at least one of the phase shifters (261, 262), the phase shifters (261, 262) may be configured to provide a first phase difference of the second signal and a second phase difference of the second signal. The phase shifters (261, 262) may be configured to have a specified phase difference between a signal before passing through the phase shifters (261, 262) and a signal after passing through the phase shifters (261, 262). For example, the specified phase difference may be about 45 degrees, but is not limited thereto. For example, the phase difference caused by the phase shifters (261, 262) may be a value determined based on the structure and performance of the electronic device (101), or the communication environment in which the electronic device (101) is used. However, the phase difference may be adjustable, without being limited thereto.

[0101] FIG. 4b is a block diagram of an electronic device according to an exemplary embodiment including a phase shifter.

[0102] Referring to FIG. 4B, the phase control unit (e.g., the phase control unit (260) of FIG. 2A) may include at least one of a first phase shifter (261) or a second phase shifter (262). The first phase shifter (261) and the second phase shifter (262) may be configured to cause a first phase difference of a second signal transmitted from a distribution circuit (250) to a second antenna radiator (242) and a second phase difference of a second signal transmitted from a distribution circuit (250) to a third antenna radiator (243).

[0103] According to an exemplary embodiment, the first phase shifter (261) may be disposed between the distribution circuit (250) and the second antenna radiator (242). The second phase shifter (262) may be disposed between the distribution circuit (250) and the third antenna radiator (243). The second signal may be output from the second RFFE circuit (232), input to the first port (251), and then output to the second port (252) and the third port (253). The second signal output to the second port (252) of the distribution circuit (250) may be input to the first phase shifter (261) along the first transmission line (P1). The first phase of the second signal input to the first phase shifter (261) may be shifted while passing through the first phase shifter (261). The second signal output to the third port (253) of the distribution circuit (250) can be input to the second phase shifter (262) along the second transmission line (P2). The second phase of the second signal input to the second phase shifter (262) can be shifted while passing through the second phase shifter (262).

[0104] The peak direction of the second radiation pattern (402) formed when the second signal having the non-shifted phase is radiated through the second antenna radiator (242) and the third antenna radiator (243) may be different from the peak direction of the second radiation pattern (402) formed when the second signal having the shifted phase is radiated through the second antenna radiator (242) and the third antenna radiator (243). As the peak direction of the second radiation pattern (402) changes, the peak direction of the first radiation pattern (401) and the peak direction of the second radiation pattern (402) may be different. As the peak direction of the first radiation pattern (401) and the peak direction of the second radiation pattern (402) are formed differently, the ECC between the first radiation pattern (401) and the second radiation pattern (402) is reduced, thereby reducing interference between the first signal and the second signal.

[0105] According to an exemplary embodiment, the first phase shifter (261) and / or the second phase shifter (262) may include a plurality of paths for a signal passing therethrough. The plurality of paths may be referred to as paths through which an input signal passes through the interior of the first phase shifter (261) and / or the second phase shifter (262). Each of the plurality of paths may shift the phase of an output signal differently. For example, the phase of the output signal may be determined based on a parameter value (e.g., capacitance or inductance) of a passive component (e.g., capacitor and / or inductor) disposed on the plurality of paths from the first phase shifter (261) and / or the second phase shifter (262) or a length of the path.

[0106] FIG. 4c is a block diagram of an electronic device according to an exemplary embodiment including a matching circuit.

[0107] Referring to FIG. 4C, the phase control unit (e.g., the phase control unit (260) of FIG. 2A) may include at least one of a first matching circuit (263) or a second matching circuit (264). The first matching circuit (263) and the second matching circuit (264) may be configured to cause a first phase difference between a second signal transmitted from the distribution circuit (250) to the second antenna radiator (242) and a second phase difference between a second signal transmitted from the distribution circuit (250) to the third antenna radiator (243).

[0108] According to an exemplary embodiment, the first matching circuit (263) may include at least one first passive element including at least one of a capacitor or an inductor. For example, the at least one first passive element may include, but is not limited to, a first capacitor (263a) and a first inductor (263b).

[0109] According to an exemplary embodiment, the first matching circuit (263) may be disposed between the second antenna radiator (242) and the distribution circuit (250). For example, the first matching circuit (263) may be electrically connected to the first transmission line (P1). The first matching circuit (263) may be configured to shift a first phase of a second signal transmitted to the second antenna radiator (242) along the first transmission line (P1). The amount of shift of the first phase of the second signal may be determined based on a parameter value (e.g., capacitance or inductance) of at least one first passive element. For example, when the first capacitor (263a) is electrically connected to the first transmission line (P1), the amount of shift of the first phase of the second signal may be determined based on the first capacitance value of the first capacitor (263a).

[0110] According to an exemplary embodiment, the second matching circuit (264) may include at least one second passive element including at least one of a capacitor or an inductor. For example, the at least one second passive element may include, but is not limited to, a second capacitor (264a) and a second inductor (264b).

[0111] According to an exemplary embodiment, the second matching circuit (264) may be disposed between the third antenna radiator (243) and the distribution circuit (250). For example, the second matching circuit (264) may be electrically connected to the second transmission line (P2). The second matching circuit (264) may be configured to shift a second phase of a second signal transmitted to the third antenna radiator (243) along the second transmission line (P2). The amount of shift of the second phase of the second signal may be determined based on a parameter value (e.g., capacitance or inductance) of at least one second passive element. For example, when the second capacitor (264a) is electrically connected to the second transmission line (P2), the amount of shift of the second phase of the second signal may be determined based on a second capacitance value of the second capacitor (264a).

[0112] According to an exemplary embodiment, the peak direction of the second radiation pattern (402) may be different from the peak direction of the second radiation pattern (402) formed when a second signal having a shifted phase is radiated through the second antenna radiator (242) and the third antenna radiator (243). As the peak direction of the second radiation pattern (402) changes, the peak direction of the first radiation pattern (401) and the peak direction of the second radiation pattern (402) may be different. As the peak direction of the first radiation pattern (401) and the peak direction of the second radiation pattern (402) are formed differently, the ECC between the first radiation pattern (401) and the second radiation pattern (402) is reduced, thereby reducing interference between the first signal and the second signal.

[0113] FIG. 4d is a block diagram of an electronic device according to an exemplary embodiment including a second transmission line different from the first transmission line.

[0114] As described above, the phase of the second signal may be shifted through the phase control unit (260), but is not limited thereto. For example, when the first length (L1) of the second transmission line (P2) transmitted from the distribution circuit (250) to the second antenna radiator (242) and the second length (L2) of the third transmission line (P3) transmitted from the distribution circuit (250) to the third antenna radiator (243) are different, the first phase of the second signal transmitted to the second antenna radiator (242) and the second phase of the second signal transmitted to the third antenna radiator (243) may be different. As the length of the transmission line increases, the time it takes for the second signal to pass increases, which may cause a phase shift of the second signal. The first length (L1) of the first transmission line (P1) may be different from the second length (L2) of the second transmission line (P2) so as to cause a first phase difference between the second signal transmitted from the distribution circuit (250) to the second antenna radiator (242) and a second phase difference between the second signal transmitted from the distribution circuit (250) to the third antenna radiator (243). The phase change due to the difference between the first length (L1) and the second length (L2) causes a change in the peak direction of the second radiation pattern (402), thereby reducing interference between the first signal and the second signal.

[0115] According to an exemplary embodiment, the phase may be shifted based on the width of the transmission line. For example, since the width of the transmission line of the signal affects the impedance, the narrower the transmission line, the higher the impedance may be. As the impedance increases, the phase of the signal may be delayed, and thus the phase of the signal may be shifted. According to an exemplary embodiment, the first width of the first transmission line (P1) may be different from the second width of the second transmission line (P2) so as to cause a first phase difference of the second signal transmitted from the distribution circuit (250) to the second antenna radiator (242) and a second phase difference of the second signal transmitted from the distribution circuit (250) to the third antenna radiator (243). The phase change due to the difference between the first width and the second width causes a change in the peak direction (D2) of the second radiation pattern (402), thereby reducing interference between the first signal and the second signal.

[0116] FIG. 5 is a flowchart illustrating an operation of an electronic device according to an exemplary embodiment to adjust a phase difference based on the quality of a signal.

[0117] According to an exemplary embodiment, at least one processor (e.g., at least one processor (210) of FIG. 2A) may be configured to control a phase shift unit (e.g., a phase shift unit (260) of FIG. 2A) to adjust the phase shift amount of a signal by the phase shift unit (260). For example, when a path along which a second signal passes through the interior of a phase shifter (e.g., a first phase shifter (261) and / or a second phase shifter (262) of FIG. 4B) is changed, the phase shift amount of the second signal may be changed. For example, when at least one passive element of a matching circuit (e.g., a first matching circuit (263) and a second matching circuit (264) of FIG. 4C) electrically connected to a transmission line is changed, the phase shift amount of the second signal may be changed.

[0118] For example, the phase control unit can be controlled by at least one processor (e.g., at least one processor (210) of FIG. 2A). The at least one processor (210) can identify communication performance and, if the communication performance is low, control the phase control unit to change the phase of the output signal. When the phase of the output signal is changed, the difference between the first phase of the second signal provided to the second antenna radiator (e.g., the second antenna radiator (242) of FIG. 2A) and the second phase of the second signal provided to the third antenna radiator (e.g., the third antenna radiator (243) of FIG. 2A) can be changed. The change in the phase difference can improve the communication performance by causing a change in the peak direction of the second radiation pattern.

[0119] Referring to FIG. 5, at operation 501, the instructions, when individually or collectively executed by at least one processor (e.g., at least one processor (210) of FIG. 2A), may cause an electronic device (e.g., the electronic device (101) of FIG. 2A) to identify a parameter value indicative of the quality of a first signal.

[0120] According to an exemplary embodiment, the electronic device (101) may perform a MIMO operation using a first antenna radiator (e.g., the first antenna radiator (241) of FIG. 2A), a second antenna radiator (e.g., the second antenna radiator (242) of FIG. 2A), and a third antenna radiator (e.g., the third antenna radiator (243) of FIG. 2A). The first antenna radiator (241) may transmit and / or receive a first signal on a first frequency band. While the first signal is being transmitted and / or received, the second antenna radiator (242) and the third antenna radiator (243) may transmit and / or receive a second signal on a second frequency band that at least partially overlaps the first frequency band. A first radiation pattern (e.g., the first radiation pattern (401) of FIG. 4A) may be formed from the first antenna radiator (241), and a second radiation pattern (e.g., the second radiation pattern (402) of FIG. 4A) may be formed from the second antenna radiator (242) and the third antenna radiator (243). The peak direction of the second radiation pattern may be determined based on the state of the phase control unit (260). For example, depending on the state of the phase control unit (260), the difference between the first phase of the second signal provided to the second antenna radiator (242) and the second phase of the second signal provided to the third antenna radiator (243) may be different. Based on the difference between the first phase and the second phase, the peak direction of the second radiation pattern may be determined.

[0121] According to an exemplary embodiment, the quality of the first signal may vary depending on the peak direction of the second radiation pattern. For example, when the peak direction of the second radiation pattern is different from the peak direction of the first radiation pattern, the quality of the first signal may be improved by reducing interference by the second signal. If the difference between the first phase and the second phase caused by the phase control unit is not appropriate, the peak direction of the first radiation pattern and the peak direction of the second radiation pattern may be substantially the same or similar, thereby deteriorating the quality of the first signal. For example, at least one processor (210) may be configured to identify a parameter value indicating the quality of the first signal in a first state of the phase control unit (260).

[0122] In the present disclosure, the parameter value indicating the quality of a signal may be at least one of RSSI (received signal strength indicator), RSRP (reference signal received power), BRSRP (beam reference signal received power), RSRQ (reference signal received quality), SINR (signal to interference and noise ratio), CINR (carrier to interference and noise ratio), SNR (signal to noise ratio), EVM (error vector magnitude), BER (bit error rate), or BLER (block error rate). In addition to the examples described above, other terms having equivalent technical meanings or other metrics indicating channel quality may be used. In the present disclosure, a high parameter value indicating signal quality indicates a case where a signal quality value related to a signal magnitude is high or a signal quality value related to an error rate is low. For example, a higher parameter value indicating a first signal quality may indicate less interference of a second signal with respect to the first signal.

[0123] At operation 502, the instructions, when individually or collectively executed by at least one processor (210), may cause the electronic device (101) to compare a parameter with a threshold value.

[0124] For example, the threshold value is a reference value indicating interference between the first signal and the second signal, and a parameter value greater than the threshold value may indicate a state in which the interference is small and the communication quality is good. A parameter value less than the threshold value may indicate a state in which the interference is large and the communication quality is deteriorated. If a parameter value less than the threshold value is identified, operation 503 may be performed. If a parameter value greater than the threshold value is identified, the communication quality is good, and thus the operation may be terminated.

[0125] At operation 503, the instructions, when individually or collectively executed by at least one processor (210), may cause the phase adjuster (260) to control. In an exemplary embodiment, the at least one processor (210) may be configured to control the phase adjuster (260) based on identifying a parameter value that is below a threshold value. For example, the at least one processor (210) may be configured to change a path through which a signal passes among a plurality of paths within the phase shifter (261, 262) in order to adjust a peak direction of the second radiation pattern (e.g., the second radiation pattern (402) of FIG. 4A). Since the degree of phase adjusted for each of the plurality of paths within the phase shifter (261, 262) is different, the phase of the second signal may be changed based on the path selection within the phase shifter (261, 262). For example, at least one processor (210) may be configured to control the matching circuit (263, 264) to adjust the peak direction of the second radiation pattern. By controlling the matching circuit (263, 264), the impedance of the second transmission line (e.g., the second transmission line (P2) of FIG. 2A) or the third transmission line (e.g., the third transmission line (P3) of FIG. 2A) may be adjusted, thereby changing the phase of the second signal. As the phase of the second signal is changed, the peak direction of the second radiation pattern may be changed, thereby changing the quality of the first signal.

[0126] According to an exemplary embodiment, after operation 503 is performed, operation 501 may be performed again. When operation 501 is performed again, a parameter value may be identified for the first signal after the phase control unit (260) is controlled. If the parameter value of the first signal identified again is less than a threshold value, at least one processor (210) may control the phase control unit (260) again until the quality of the first signal is improved by controlling the phase control unit (260). If the parameter value of the first signal identified again is equal to or greater than the threshold value, the quality of the first signal is good, and therefore, at least one processor (210) may be configured to terminate the operation.

[0127] FIG. 6 is a flowchart illustrating an operation of an electronic device according to an exemplary embodiment to adjust a phase difference based on the identification of a grip.

[0128] An electronic device (e.g., the electronic device (101) of FIG. 2A) according to an exemplary embodiment may include a sensor (e.g., the grip sensor (290) of FIG. 2A) for identifying a user's grip on the electronic device (101). Due to the user's grip, it may be difficult to maintain the communication performance of the electronic device (101). For example, if the user holds a part of the antenna radiator with his / her hand, it may be difficult to transmit and receive signals by the user's hand. The electronic device (101) according to an exemplary embodiment may be configured to control a peak direction of a second radiation pattern (e.g., the second radiation pattern (402) of FIG. 4A) by controlling a phase control unit (e.g., the phase control unit (260) of FIG. 2A) when the user's grip is identified.

[0129] Referring to FIG. 6, at operation 601, the instructions, when individually or collectively executed by at least one processor (e.g., at least one processor (210) of FIG. 2A), may cause the electronic device (101) to identify the user's grip via a grip sensor (e.g., grip sensor (290) of FIG. 2A).

[0130] According to an exemplary embodiment, the grip sensor (290) may be configured to measure a capacitance change according to a user's grip on a housing (e.g., the housing (301) of FIG. 3) defining an exterior of the electronic device (101). When the user's body and the housing (301) come into contact, the contact may cause a change in the capacitance value of the grip sensor (290). The grip sensor (290) may be configured to provide information about the capacitance value to at least one processor (210). The at least one processor (210) may be configured to identify a capacitance value from the information, and identify the user's grip on the housing (301) based on whether the capacitance value corresponds to a reference value representing the user's grip. For example, the reference value may be set to a capacitance value caused by contact with the user's body.

[0131] At operation 603, the instructions, when individually or collectively executed by at least one processor (210), may cause the electronic device (101) to identify a first parameter value indicative of a quality of the first signal.

[0132] According to an exemplary embodiment, when the user's grip is identified, the electronic device (101) may be configured to identify a first parameter value indicating the quality of the first signal to verify communication performance. The first parameter value is a term distinct from the second parameter value described below, and may be referred to as a parameter value identified before controlling the phase control unit (e.g., the phase control unit (260) of FIG. 2A). For example, when the quality of the first signal is degraded by the user's grip, the parameter value indicating the quality of the first signal may be reduced. In the operation described below, the state of the phase control unit (260) may indicate a state in which the phase shifter or matching circuit is specified to provide a specific amount of phase shift.

[0133] At operation 605, the instructions, when individually or collectively executed by at least one processor (210), may cause the electronic device (101) to identify a first state of the phase control unit (260) based on identifying a first parameter value that is below a threshold value.

[0134] According to an exemplary embodiment, at least one processor (210) may be configured to identify a first state, which is a current state of the phase adjustment unit (260), when the identified first parameter value is less than a threshold value. The threshold value is a reference value indicating interference between the first signal and the second signal, and a parameter value less than the threshold value may indicate a state in which the interference is large and the communication quality is deteriorated. When it is identified that the communication quality is deteriorated, at least one processor (210) may identify the first state, which is a current state, in order to change the state of the phase adjustment unit (260).

[0135] At operation 607, the instructions, when individually or collectively executed by at least one processor (210), may cause the phase control unit (260) to change a state to a second state and identify a second parameter value indicative of the quality of the first signal.

[0136] According to an exemplary embodiment, at least one processor (210) may control the phase adjustment unit (260) to change the state of the phase adjustment unit (260) from the first state to the second state in order to improve communication performance. Since the peak direction of the second radiation pattern (e.g., the second radiation pattern (402) of FIG. 4A) is determined according to the state of the phase adjustment unit (260), the first state may indicate a state in which the first signal and the second signal interfere with each other, since the peak direction of the second radiation pattern is substantially the same as or similar to the peak direction of the first radiation pattern (e.g., the first radiation pattern (401) of FIG. 4A). The at least one processor (210) may be configured to, after changing the phase adjustment unit (260) to the second state, identify the second parameter value indicating the quality of the first signal again.

[0137] At operation 609, the instructions, when individually or collectively executed by at least one processor (210), may cause the state of the phase control unit (260) to be maintained in the second state based on identifying a second parameter value greater than or equal to a threshold value.

[0138] According to an exemplary embodiment, when at least one processor (210) identifies that the second parameter value is greater than or equal to a threshold value, the second state may be determined to be a state that improves the communication performance of the electronic device (101). As the state of the phase control unit (260) changes to the second state, the peak direction of the second radiation pattern may change, thereby reducing interference between the first signal and the second signal. When at least one processor (210) identifies that the second parameter value is greater than or equal to the threshold value, the state of the phase control unit (260) may be configured to maintain the state of the phase control unit (260) in the second state. If the second parameter value identified in the second state of the phase control unit (260) is less than the threshold value, the at least one processor (210) may control the phase control unit (260) until a parameter value less than the threshold value is identified.

[0139] According to an exemplary embodiment, at least one processor (210) can adjust the phase of the second signal by controlling the phase adjustment unit (260). As the phase is adjusted, the peak direction of the second radiation pattern can be adjusted, thereby reducing the deterioration of communication performance for the grip. At least one processor (210) can improve communication performance by controlling the phase adjustment unit (260) so as to overcome the deterioration of communication performance for the grip.

[0140] Figure 7a illustrates the efficiency of the antennas. Figure 7b illustrates an electronic device utilizing a second antenna radiator. Figure 7c illustrates an electronic device utilizing both a second antenna radiator and a third antenna radiator.

[0141] The graphs shown in Figure 7a represent the gain for each of the antennas, including antenna radiators. The x-axis of the graph represents frequency in GHz (giga hertz) and the y-axis represents efficiency in dB (decibel).

[0142] The first graph (701) of Fig. 7a represents the efficiency of an antenna (e.g., a first antenna) including a first antenna radiator (e.g., the first antenna radiator (241) of Fig. 2a) with respect to a frequency. Referring to Fig. 7b or Fig. 7c, when the first feeding point (F1) of the first conductive portion (311) operating as the first antenna radiator (241) is fed from the first RFFE circuit (231), a first antenna having an efficiency similar to that of the first graph (701) of Fig. 7a can be formed.

[0143] The second graph (702) of FIG. 7a represents the efficiency of an antenna (e.g., a second antenna) including a second antenna radiator (e.g., the second antenna radiator (242) of FIG. 2a) with respect to frequency. Referring to FIG. 7b, when a second signal is fed to a second feed point (F2) of a second conductive portion (312) along a first transmission line (P1) from a second RFFE circuit (232), a second antenna having an efficiency similar to that of the second graph (702) of FIG. 7a can be formed.

[0144] The third graph (703) of FIG. 7a represents the efficiency of an antenna (e.g., a third antenna) including a second antenna radiator (242) and a third antenna radiator (e.g., the third antenna radiator (243) of FIG. 2a) with respect to frequency. Referring to FIG. 7c, the third antenna including the second antenna radiator (242) and the third antenna radiator (243) is referred to as an antenna in which a signal provided from the second RFFE circuit (232) is fed to a second feed point (F2) of a second conductive portion (312) operating as a second antenna radiator (242) and a third feed point (F3) of a third conductive portion (313) operating as a third antenna radiator (243), respectively, through a distribution circuit (250). The difference between the first phase of the second signal provided to the second antenna radiator (242) and the second phase of the second signal provided to the third antenna radiator (243) is referred to as approximately 90 degrees. When the second feeding point (F2) and the third feeding point (F3) are fed, a third antenna having an efficiency similar to the third graph (703) of FIG. 7A can be formed.

[0145] Comparing the second antenna and the third antenna, the second antenna can transmit and / or receive a signal through the second antenna radiator (242) by providing a second signal provided from the second RFFE circuit (e.g., the second RFFE circuit (232) of FIG. 2A) to the second antenna radiator (242). The third antenna can transmit and / or receive a signal through the second antenna radiator (242) and the third antenna radiator (243) by providing a second signal provided from the second RFFE circuit (232) to each of the second antenna radiator (242) and the third antenna radiator (243).

[0146] Referring to the first graph (701), the efficiency of the first antenna is about 0.39 dB for a frequency of about 3.5 GHz. Referring to the second graph (702), the efficiency of the second antenna is about 0.29 dB for a frequency of about 3.5 GHz. Referring to the third graph (703), the efficiency of the third antenna may be about 0.6 dB higher than the efficiency of the second antenna. In the case of the third antenna, the difference between the first phase of the second signal provided to the second antenna radiator (242) and the second phase of the second signal provided to the third antenna radiator (243) forms about 90 degrees, so that the peak direction of the radiation pattern (e.g., the second radiation pattern (402) of FIG. 4A) according to the second signal of the first phase and the second signal of the second phase can be adjusted. As the peak directions of the radiation patterns according to the second signal of the first phase and the second signal of the second phase are adjusted, the peak directions of the radiation pattern by the first signal (e.g., the first radiation pattern (401) of FIG. 4A) and the peak directions of the radiation pattern by the second signal may be different. As the peak directions are formed differently from each other, the efficiency of the third antenna may be improved by about 10% compared to the efficiency of the second antenna. In the case of the second antenna, the peak directions of the radiation pattern by the first signal and the peak directions of the radiation pattern by the second signal are substantially the same or similar, so that interference between the first signal and the second signal may be relatively large. Due to the interference, the efficiency of the second antenna may be lower than the efficiency of the third antenna.

[0147] Referring to FIG. 7A, when a first signal is transmitted and / or received through a first antenna radiator (241), it can be confirmed that communication performance is deteriorated due to interference between radiation patterns when only the second antenna radiator (242) is used. The electronic device (101) according to an exemplary embodiment can improve communication performance by transmitting and / or receiving a second signal on a second frequency band that at least partially overlaps the first frequency band using the second antenna radiator (242) and the third antenna radiator (243). Based on the difference between the first phase of the second signal transmitted to the second antenna radiator (242) and the second phase of the second signal transmitted to the third antenna radiator (243), the communication performance can be improved as the peak direction of the radiation pattern according to the second signal is adjusted.

[0148] According to an exemplary embodiment, depending on the phase difference, the interference between the first antenna and the third antenna may be changed to be smaller than the interference between the first antenna and the second antenna. For a signal having a frequency of about 3.5 GHz, the ECC between the first antenna and the second antenna may be about 0.283. Table 1 below shows the ECC (envelope correlation coefficient) between the first antenna and the third antenna according to the first phase and the second phase difference for a signal having a frequency of about 3.5 GHz. The ECC is a parameter indicating how independent the radiation patterns are, and the larger the ECC, the greater the interference between the radiation patterns, and the smaller the ECC, the smaller the interference between the radiation patterns.

[0149]

[0150] Referring to the above [Table 1], the ECC between the first antenna and the third antenna is smaller than the ECC between the first antenna and the second antenna. For example, when the first phase and the second phase difference are about 45 degrees, the ECC is reduced to 0.004, and it can be confirmed that the ECC between the first antenna and the third antenna is reduced to about 1 / 70 of the ECC between the first antenna and the second antenna, which is 0.283. The exemplary electronic device (101) can stably perform MIMO operation using the first antenna and the third antenna, which can operate substantially independently. As the MIMO operation is stably performed, the data processing capacity of the electronic device (101) can increase.

[0151] Figure 8 illustrates the radiation patterns of each of the first antenna, the second antenna, and the third antenna.

[0152] The first antenna may be referred to as an antenna including a first antenna radiator (e.g., the first antenna radiator (241) of FIG. 2A). The second antenna may be referred to as an antenna including a second antenna radiator (e.g., the second antenna radiator (242) of FIG. 2A). The third antenna may be referred to as an antenna that uses a second antenna radiator (e.g., the second antenna radiator (242) of FIG. 2A) and a third antenna radiator (e.g., the third antenna radiator (243) of FIG. 2A) as a single antenna radiator.

[0153] The radiation pattern illustrated in FIG. 8 can be obtained by measuring the electric field strength of electromagnetic waves radiated from antennas while rotating the azimuth by 360 degrees for an electronic device (101) in a fixed posture with an elevation angle of 90 degrees, and displaying the results according to the azimuth. For example, the distance from the pole represents the electric field strength, and the angle with respect to the polar axis represents the azimuth. An angle of 0 degrees represents the direction in which the front of the electronic device (101) faces. An angle of 180 degrees with respect to the polar axis represents the direction in which the rear of the electronic device (101) faces. An angle of 90 degrees with respect to the polar axis represents the direction in which the upper part of the electronic device (101) faces. An angle of 270 degrees with respect to the polar axis represents the direction in which the lower part of the electronic device (101) faces.

[0154] The first radiation pattern (801) of Fig. 8 is a radiation pattern for the first antenna. The second radiation pattern (802) of Fig. 8 is a radiation pattern for the second antenna. The third radiation pattern (803) of Fig. 8 is a radiation pattern for the third antenna.

[0155] Referring to FIG. 8, the first radiation pattern (801) may exhibit a peak characteristic at an azimuth angle of about 240 degrees. The second radiation pattern (802) may exhibit a peak characteristic at an azimuth angle of about 230 degrees. Since the azimuth angles at which the peak characteristics of the first radiation pattern (801) and the peak characteristics of the second radiation pattern (802) appear are similar, the peak direction of the first radiation pattern (801) and the peak direction of the second radiation pattern (802) may be similar. Since the shapes and peak directions of the first radiation pattern (801) and the second radiation pattern (802) are similar to each other, the ECC may be high, and the spatial diversity effect may be low in MIMO operation, so that the communication performance may deteriorate. Referring to the above [Table 1], the reason why the ECC between the first antenna and the second antenna is relatively high is because the first radiation pattern (801) and the second radiation pattern (802) have similar shapes and similar peak directions.

[0156] Referring to the third radiation pattern (803), the peak characteristic of the third radiation pattern (803) may exhibit a peak characteristic at an azimuth angle of about 90 degrees. The third radiation pattern (803) is a radiation pattern formed by the third antenna, and the peak direction may be changed by the difference between the first phase of the second signal provided to the second antenna radiator (242) and the second phase of the second signal provided to the third antenna radiator (243). The peak direction changed by the phase difference causes the peak characteristic of the third radiation pattern (803) to be different from the peak characteristic of the first radiation pattern (801), thereby allowing the first radiation pattern (801) and the third radiation pattern (803) to have different shapes and different peak directions. When the first antenna and the third antenna operate together for MIMO operation, the deterioration of communication performance may be reduced. For example, when the first antenna and the third antenna operate together, the throughput of data may be increased. Referring to the above [Table 1], the ECC between the first antenna and the third antenna is relatively low because the first radiation pattern (801) and the third radiation pattern (803) have different shapes and different peak directions.

[0157] Referring to FIG. 8, the exemplary electronic device (101) can reduce interference between the first antenna and the third antenna by using the third antenna instead of the second antenna. In order to use the third antenna, the electronic device (101) can include a distribution circuit (e.g., the distribution circuit (250) of FIG. 2A) and a phase shifter (e.g., the phase shifter (260) of FIG. 2A). The electronic device (101) can provide improved communication performance by transmitting and / or receiving the first signal and the second signal using the first antenna and the third antenna.

[0158] FIGS. 9A, 9B, and 9C are diagrams schematically illustrating a process of controlling directivity of an electronic device according to an exemplary embodiment.

[0159] Referring to FIG. 9A, the exemplary electronic device (101) may further include a fourth antenna radiator and a fifth antenna radiator. The fourth antenna radiator may be implemented as a fourth conductive portion (314). The fifth antenna radiator may be implemented as a fifth conductive portion (315). According to an exemplary embodiment, the fourth conductive portion (314) may be disposed between the fourth non-conductive portion (324) and the fifth non-conductive portion (325). The fifth conductive portion (315) may be in contact with the fifth non-conductive portion (325).

[0160] An electronic device (101) according to an exemplary embodiment may further include a fourth RFFE circuit (234), a fifth RFFE circuit (235), another distribution circuit (910), a third phase shifter (265), a fourth phase shifter (266), and / or another diplexer (920). Either the third phase shifter (265) or the fourth phase shifter (266) may be omitted. The other distribution circuit (910) may be connected to each of the fourth antenna radiator and the fifth antenna radiator. The fourth RFFE circuit (234) may be electrically connected to the fourth antenna radiator and the fifth antenna radiator via the other distribution circuit (910). The third phase shifter (265) may be disposed between the other distribution circuit (910) and the fourth antenna radiator. The fourth phase shifter (266) may be disposed between the other distribution circuit (910) and the fifth antenna radiator. The fifth RFFE circuit (235) may be electrically connected to the fifth antenna radiator. Another diplexer (920) may be electrically connected to the fifth antenna radiator (e.g., the fifth conductive portion (315)). Within FIGS. 9A, 9B, and 9C, the electronic device (101) is illustrated as including another diplexer (920), but as described above, the other diplexer (920) may be replaced with a first band pass filter or a second band pass filter. Within FIGS. 9A, 9B, and 9C, the electronic device (101) is illustrated as including a third phase shifter (265) and / or a fourth phase shifter (266), but as described above, the third phase shifter (265) and / or the fourth phase shifter (266) may be replaced with a matching circuit.

[0161] According to an exemplary embodiment, the fourth RFFE circuit (234) may be configured to provide a signal on a fourth frequency band. The fourth RFFE circuit (234) may be electrically connected to a fourth antenna radiator (e.g., the fourth conductive portion (314)) and a fifth antenna radiator (e.g., the fifth conductive portion (315)) via another distribution circuit (910). In the following description, the fourth antenna radiator is described as the fourth conductive portion (314), and the fifth antenna radiator is described as the fifth conductive portion (315).

[0162] According to an exemplary embodiment, the electronic device (101) may perform a MIMO operation using three antennas. Referring to FIG. 9A, when the electronic device (101) performs a MIMO operation through the first conductive portion (311), the second conductive portion (312), and the fourth conductive portion (314), radiation patterns (901, 902) having substantially the same or similar peak directions may be formed. When a first signal is transmitted and / or received through the first conductive portion (311), and a second signal is transmitted and / or received through the second conductive portion (312) and the third conductive portion (313), the peak direction of the first radiation pattern (901) by the first signal and the peak direction of the second radiation pattern (902) by the second signal may be formed to be substantially the same or similar. When the peak direction of the first radiation pattern (901) and the peak direction of the second radiation pattern (902) are formed to be substantially the same or similar, interference may occur between the first signal and the second signal, which may deteriorate the communication performance of the electronic device (101). The fourth RFFE circuit (234) may transmit and / or receive the fourth signal through the fourth conductive portion (314). In the case of the fourth conductive portion (314), since it is arranged relatively farther away from the first conductive portion (311) than the second conductive portion (312) and is substantially perpendicular to the first conductive portion (311), the third radiation pattern (903) by the fourth signal may be formed differently from the first radiation pattern (901) and the second radiation pattern (902).

[0163] Referring to FIG. 9B, the second signal provided from the second RFFE circuit (232) can be transmitted to the second conductive portion (312) and the third conductive portion (313) through the distribution circuit (250). Due to the difference between the first phase of the second signal transmitted to the second conductive portion (312) and the second phase of the second signal transmitted to the third conductive portion (313), the peak direction of the fourth radiation pattern (904) can be different from the peak direction of the first radiation pattern (901). By adjusting the peak direction by the phase difference, interference between the first signal and the second signal can be reduced, but when the peak direction of the third radiation pattern (903) and the peak direction of the fourth radiation pattern (904) are formed similarly, interference between the second signal and the fourth signal can occur.

[0164] Referring to FIG. 9C, a fourth signal provided from a fourth RFFE circuit (234) can be provided to a fourth conductive portion (314) and a fifth conductive portion (315) through another distribution circuit (910). The third phase of the fourth signal transmitted to the fourth conductive portion (314) and the fourth phase of the fourth signal transmitted to the fifth conductive portion (315) can be different by the third phase shifter (265) and / or the fourth phase shifter (266). The difference between the third phase and the fourth phase can adjust the peak direction of the fifth radiation pattern (905) according to the fourth signal. As illustrated in FIG. 9C, since the peak direction of the fifth radiation pattern (905) by the fourth signal and the peak direction of the fourth radiation pattern (904) are formed differently, interference between the second signal and the fourth signal can be reduced. Since the peak directions of the first radiation pattern (901), the fourth radiation pattern (904), and the fifth radiation pattern (905) are formed differently from each other, the communication performance of the electronic device (101) performing the MIMO operation can be improved. According to an exemplary embodiment, the fifth conductive portion (315) can operate as a separate antenna radiator (e.g., the fifth antenna radiator) when powered by the fifth RFFE circuit (235). The electronic device (101) can include another diplexer (920) for the fifth antenna radiator.

[0165] FIGS. 10A, 10B, and 10C are block diagrams of an electronic device according to an exemplary embodiment including a switch circuit.

[0166] As described above, the electronic device (101) may use a first antenna radiator (e.g., the first antenna radiator (241) of FIG. 2A), a second antenna radiator (e.g., the second antenna radiator (242) of FIG. 2A) and a third antenna radiator (e.g., the third antenna radiator (243) of FIG. 2A) for MIMO operation. According to an exemplary embodiment, the electronic device (101) may be configured to change the antenna radiator to be used together with the first antenna radiator (241) for performing the MIMO operation using an artificial intelligence model. For example, the second signal may be transmitted and / or received using the second antenna radiator (242) and the third antenna radiator (243), and then the second signal may be transmitted and / or received using the second antenna radiator (242) and the fourth antenna radiator (244).

[0167] Referring to FIG. 10A, an electronic device (101) according to an exemplary embodiment may further include a switch circuit (1010). The switch circuit (1010) may be disposed between a distribution circuit (e.g., distribution circuit (350) of FIG. 2A) and a fourth antenna radiator (244). For example, the switch circuit (1010) may include a first port (1011) connected to the distribution circuit (350), a second port (1012) connected to the third antenna radiator (243), and a third port (1013) connected to the fourth antenna radiator (244).

[0168] The embodiment illustrated in FIG. 10A may correspond to the embodiment illustrated in FIG. 2A. For example, if the electronic device (101) includes a diplexer (e.g., the diplexer (271) of FIG. 2A), the switch circuit (1010) may be disposed between the distribution circuit (350) and the diplexer (271). The electronic device (101) may control the switch circuit (1010) using an artificial intelligence model to provide a state with high communication performance (e.g., throughput). For example, while a first signal is transmitted and / or received through the first antenna radiator (241), the switch circuit (1010) may be controlled to a first state in which the first port (1011) and the second port (1012) are connected in order to transmit and / or receive a second signal using the second antenna radiator (242) and the third antenna radiator (243). For example, while a first signal is transmitted and / or received through a first antenna radiator (241), in order to transmit and / or receive a second signal using a second antenna radiator (242) and a fourth antenna radiator (244), the switch circuit (1010) may be controlled to a second state in which the first port (1011) and the third port (1013) are connected. The artificial intelligence model may determine which state provides higher communication performance among the first state and the second state based on the usage conditions, communication environment, or data throughput of the electronic device (101). The electronic device (101) may control the switch circuit (1010) based on the result determined using the artificial intelligence model. The electronic device (101) may further include a filtering circuit (1020) electrically connected to the fourth antenna radiator (243). For example, the filtering circuit (1020) may include a diplexer configured to separate the second signal and the fourth signal.

[0169] The embodiment illustrated in FIG. 10B may correspond to the embodiment illustrated in FIG. 2B. For example, when the electronic device (101) includes a first band-pass filter (e.g., the first band-pass filter (272) of FIG. 2B), the switch circuit (1010) may be disposed between the first band-pass filter (272) and the third antenna radiator (243). The electronic device (101) may control the switch circuit (1010) using an artificial intelligence model to provide a state with high communication performance. For example, while a first signal is transmitted and / or received through the first antenna radiator (241), in order to transmit and / or receive a second signal using the second antenna radiator (242) and the third antenna radiator (243), the switch circuit (1010) may be controlled to a first state in which the first port (1011) and the second port (1012) are connected. For example, while a first signal is transmitted and / or received through a first antenna radiator (241), in order to transmit and / or receive a second signal using a second antenna radiator (242) and a fourth antenna radiator (244), the switch circuit (1010) can be controlled to a second state in which the first port (1011) and the third port (1013) are connected.

[0170] The embodiment illustrated in FIG. 10c may correspond to the embodiment illustrated in FIG. 2c. For example, when the electronic device (101) includes a second bandpass filter (e.g., the second bandpass filter (273) of FIG. 2c), the switch circuit (1010) may be disposed between the distribution circuit (350) and the third antenna radiator (243). The electronic device (101) may control the switch circuit (1010) using an artificial intelligence model to provide a state with high communication performance. For example, while a first signal is transmitted and / or received through the first antenna radiator (241), in order to transmit and / or receive a second signal using the second antenna radiator (242) and the third antenna radiator (243), the switch circuit (1010) may be controlled to a first state in which the first port (1011) and the second port (1012) are connected. For example, while a first signal is transmitted and / or received through a first antenna radiator (241), in order to transmit and / or receive a second signal using a second antenna radiator (242) and a fourth antenna radiator (244), the switch circuit (1010) may be controlled to a second state in which the first port (1011) and the third port (1013) are connected. The electronic device (101) may further include a filtering circuit (1020) electrically connected to the fourth antenna radiator (243). For example, the filtering circuit (1020) may include a band pass filter configured to pass the fourth signal.

The first phase shifter (261) or the second phase shifter (262) may be configured to cause a first phase difference between the second signal transmitted from the distribution circuit (250) to the second antenna radiator (242) and a second phase difference between the second signal transmitted from the distribution circuit (250) to the third antenna radiator (243).

[0173] According to an exemplary embodiment, the electronic device (101) may further include a first transmission line (P1) between the distribution circuit (250) and the second antenna radiator (242).
