[0051] Battery 189 can power at least one component of electronic device 101. According to an embodiment, battery 189 may include, for example, a non-rechargeable primary battery, a rechargeable secondary battery, or a fuel cell.

[0052] Communication module 190 can support establishing a direct (e.g., wired) or wireless communication channel between electronic device 101 and external electronic devices (e.g., electronic device 102, electronic device 104, or server 108), and perform communication via the established communication channel. Communication module 190 may include one or more communication processors that can operate independently of processor 120 (e.g., application processor (AP)) and support direct (e.g., wired) or wireless communication. According to embodiments, communication module 190 may include wireless communication module 192 (e.g., cellular communication module, short-range wireless communication module, or Global Navigation Satellite System (GNSS) communication module) or wired communication module 194 (e.g., local area network (LAN) communication module or power line communication (PLC) module). A corresponding one of these communication modules can communicate with external electronic devices via a first network 198 (e.g., a short-range communication network, such as Bluetooth™). These various types of communication modules can be implemented as a single component (e.g., a single chip), or they can be implemented as multiple components (e.g., multiple chips) that are separate from each other. The wireless communication module 192 can use user information (e.g., International Mobile Subscriber Identity (IMSI)) stored in the user identification module 196 to identify and verify electronic devices 101 in a communication network (such as a first network 198 or a second network 199).

[0053] Wireless communication module 192 can support 5G networks and next-generation communication technologies beyond fourth-generation (4G) networks, such as new radio (NR) access technologies. NR access technologies can support enhanced mobile broadband (eMBB), massive machine-type communication (mMTC), or ultra-reliable and low-latency communication (URLLC). Wireless communication module 192 can support high-frequency bands (e.g., millimeter-wave bands) to achieve, for example, high data transmission rates. Wireless communication module 192 can support various technologies used to ensure performance in high-frequency bands, such as beamforming, massive MIMO, full-dimensional MIMO (FD-MIMO), array antennas, analog beamforming, or massive antennas. Wireless communication module 192 can support various requirements specified in electronic device 101, external electronic device (e.g., electronic device 104), or network system (e.g., second network 199). According to an embodiment, the wireless communication module 192 may support peak data rates (e.g., 20 Gbps or higher) for implementing eMBB, loss coverage (e.g., 164 dB or lower) for implementing mMTC, or U-plane delay (e.g., 0.5 ms or less for each of the downlink (DL) and uplink (UL), or 1 ms or less round trip) for implementing URLLC.

[0054] Antenna module 197 can transmit or receive signals or power to or from the outside of electronic device 101 (e.g., external electronic device). According to an embodiment, antenna module 197 may include an antenna comprising a radiating element formed of a conductive material or conductive pattern formed in or on a substrate (e.g., a printed circuit board (PCB)). According to an embodiment, antenna module 197 may include multiple antennas (e.g., an array antenna). In this case, at least one antenna suitable for a communication scheme used in a communication network (such as a first network 198 or a second network 199) can be selected from the multiple antennas, for example by communication module 190 (e.g., wireless communication module 192). Signals or power can then be transmitted or received between communication module 190 and external electronic device via the selected at least one antenna. According to an embodiment, another component besides the radiating element (e.g., a radio frequency integrated circuit (RFIC)) may be additionally incorporated into antenna module 197.

[0055] According to various embodiments, antenna module 197 can form a millimeter-wave antenna module. According to embodiments, the millimeter-wave antenna module may include: a printed circuit board; an RFIC disposed on or adjacent to a first surface (e.g., bottom surface) of the printed circuit board and capable of supporting a specified high-frequency band (e.g., millimeter-wave band); and a plurality of antennas (e.g., array antennas) disposed on or adjacent to a second surface (e.g., top or side surface) of the printed circuit board and capable of transmitting or receiving signals in the specified high-frequency band.

[0056] At least some of the aforementioned components may be coupled to each other and transmit signals (e.g., commands or data) between them via a peripheral communication scheme (e.g., bus, general purpose input and output (GPIO), serial peripheral interface (SPI), or mobile industrial processor interface (MIPI)).

[0057] According to an embodiment, commands or data can be sent or received between electronic device 101 and external electronic device 104 via server 108 connected to a second network 199. Each of electronic devices 102 or 104 can be a device of the same or different type as electronic device 101. According to an embodiment, all or some operations to be performed at electronic device 101 can be performed at one or more of external electronic devices 102, 104, or 108. For example, if electronic device 101 is required to automatically perform a function or service, or in response to a request from a user or another device, electronic device 101 may request one or more external electronic devices to perform at least a portion of the function or service, rather than performing the function or service, or may request one or more external electronic devices to perform at least a portion of the function or service in addition to performing the function or service. Upon receiving the request, one or more external electronic devices may perform at least a portion of the requested function or service, or perform additional functions or services related to the request, and transmit the result of the performance to electronic device 101. Electronic device 101 may provide the result, with or without further processing, as at least part of a response to the request. For this purpose, cloud computing, distributed computing, mobile edge computing (MEC), or client-server computing technologies can be used, for example. Electronic device 101 can use, for example, distributed computing or mobile edge computing to provide ultra-low latency services. In another embodiment, external electronic device 104 may include Internet of Things (IoT) devices. Server 108 may be an intelligent server using machine learning and / or neural networks. According to embodiments, external electronic device 104 or server 108 may be included in a second network 199. Electronic device 101 can be applied to intelligent services based on 5G communication technology or IoT-related technologies (e.g., smart homes, smart cities, smart cars, or healthcare).

[0058] Electronic device 101 may include an antenna for communicating with external electronic devices (e.g., Figure 2 The first antenna 210 and the second antenna 220). For example, electronic device 101 can transmit signals to or receive signals from external electronic devices by using antennas 210 and 220. For example, electronic device 101 may include multiple antennas 210 and 220 to achieve communication diversity. For example, electronic device 101 may include a first antenna 210 and a second antenna 220, but is not limited thereto.

[0059] For example, external electronic devices may include satellites (e.g., Figure 2 (Satellite 300). For example, electronic device 101 can be configured to perform satellite communication, such as receiving signals from or sending signals to the satellite. The orbit of satellite 300 may be hundreds to tens of thousands of kilometers above the ground where electronic device 101 is located. Due to the long distance between electronic device 101 and satellite 300, radiation efficiency may be low. For example, to improve satellite communication efficiency, it may be necessary for the polarization characteristics of the first antenna 210 and the second antenna 220 to correspond to the polarization characteristics of the antennas of satellite 300.

[0060] For example, the polarization characteristics of the antenna of satellite 300 can be circular polarization. According to an exemplary embodiment, electronic device 101 can achieve circular polarization by adjusting the electrical path between the first antenna 210 and the second antenna 220 used for communication diversity and the RF transceiver 250. Since the first antenna 210 and the second antenna 220 radiate with circular polarization, satellite communication efficiency can be improved. Hereinafter, electronic device 101 according to an exemplary embodiment is described.

[0061] Figure 2 An electronic device according to an exemplary embodiment is illustrated schematically.

[0062] Reference Figure 2 According to an embodiment, the electronic device 101 may include a first antenna 210 and a second antenna 220. For example, the first antenna 210 and the second antenna 220 may be referred to as... Figure 1 Antenna modules (e.g., Figure 1 Antenna module 197). For example, the first antenna 210 and the second antenna 220 can be used to transmit and / or receive signals on a specified frequency band.

[0063] For example, electronic device 101 can use the first antenna 210 and the second antenna 220 to transmit signals according to transmit diversity. For example, electronic device 101 can use the first antenna 210 and the second antenna 220 to receive signals according to receive diversity. For example, electronic device 101 can implement diversity functionality by using signals transmitted and received through the first antenna 210 and the second antenna 220. For example, the first antenna 210 can operate as a primary antenna, and the second antenna 220 can operate as a diversity antenna. However, it is not limited to this. For example, besides... Figure 2 In addition to the first antenna 210 and the second antenna 220 shown, the electronic device 101 may also include at least one additional antenna.

[0064] For example, electronic device 101 may include frame 230. For example, frame 230 may be referred to as a frame defining at least a portion of the side of electronic device 101. For example, when electronic device 101 has a substantially rectangular shape, frame 230 may include a first edge portion 231, a second edge portion 232, a third edge portion 233, and a fourth edge portion 234.

[0065] For example, a first antenna 210 and a second antenna 220 may be formed along a portion of a frame 230. The frame 230 may include conductive and non-conductive portions. The conductive portions may serve as antenna radiators for transmitting and / or receiving signals in a specified frequency band. The non-conductive portions may contact both ends of the conductive portions serving as antenna radiators to electrically isolate the conductive portions serving as antenna radiators from other conductive portions. For example, the non-conductive portions may include, but are not limited to, polycarbonate (PC). The non-conductive portions, acting as dielectrics, may limit the length of the conductive portions operating as antenna radiators.

[0066] For example, frame 230 may include a first edge portion 231 defining at least a portion of the top (e.g., +y direction) edge of electronic device 101, a second edge portion 232 defining at least a portion of one side (e.g., +x direction) edge of electronic device 101, a third edge portion 233 opposite to the first edge portion 231, and a fourth edge portion 234 opposite to the second edge portion 232. For example, the first edge portion 231 may be perpendicular to the second edge portion 232. For example, the length of the second edge portion 232 may be longer than the length of the first edge portion 231. For example, the third edge portion 233 may define at least a portion of the bottom (e.g., -y direction) edge of electronic device 101. For example, the fourth edge portion 234 may define at least a portion of the other side (e.g., -y direction) edge of electronic device 101.

[0067] For example, the first antenna 210 may be arranged substantially perpendicular to the second antenna 220. For example, the first antenna 210 may be formed at least partially along the first edge portion 231 or the third edge portion 233. For example, the second antenna 220 may be formed at least partially along the second edge portion 232 or the fourth edge portion 234. Since the first edge portion 231 and the third edge portion 233 are perpendicular to the second edge portion 232 and the fourth edge portion 234, the first antenna 210 and the second antenna 220 may be arranged perpendicular to each other. However, this is not a limitation. For example, the first antenna 210 may be formed at least partially along the second edge portion 232 or the fourth edge portion 234, and the second antenna 220 may be formed at least partially along the first edge portion 231 or the third edge portion 233. To achieve circular polarization according to embodiments of the present disclosure, the first antenna 210 and the second antenna 220 only have a structure that is perpendicular to each other, and the positions of the first antenna 210 and the second antenna 220 are not limited to a specific location.

[0068] "An antenna is formed at least partially along an edge portion" can mean that the antenna (e.g., an antenna radiator) can be formed entirely along an edge portion, or that most of the antenna can be formed along an edge portion, while the remaining portion of the antenna can be formed along another edge portion different from the edge portion.

[0069] For example, such as Figure 2 As shown, the second antenna 220 may include the edge of the frame 230. For example, a portion of the second antenna 220 may be formed along the second edge portion 232, and the remaining portion of the second antenna 220 may be formed along the first edge portion 231. Since the portion of the second antenna 220 formed along the second edge portion 232 is larger than the remaining portion of the second antenna 220 formed along the first edge portion 231, the second antenna 220 may be described as being formed substantially along the second edge portion 232. Since a portion of the second antenna 220 is perpendicular to the first antenna 210 even when another portion of the second antenna 220 is parallel to the first antenna 210, the second antenna 220 may be described as being arranged perpendicular to the first antenna 210. For example, the first antenna 210 and the second antenna 220 formed in the frame 230 may be inverted F antennas (IFA).

[0070] For example, the first antenna 210 and the second antenna 220 can transmit and / or receive signals via a cellular network that uses a terrestrial base station to transmit and / or receive signals. The first antenna 210 and the second antenna 220 for cellular communication can be configured to radiate with linear polarization. For example, the first antenna 210 and the second antenna 220 implemented as an IFA can have linear polarization characteristics, which include a radiation pattern polarized in a vertical or horizontal direction relative to the propagation direction.

[0071] For example, electronic device 101 can use the first antenna 210 and the second antenna 220, which are used for cellular communication, for satellite communication. For example, electronic device 101 can transmit and / or receive signals in a satellite communication frequency band (e.g., approximately 1.6 GHz) by using the first antenna 210 and the second antenna 220.

[0072] For example, the received power received through the antenna can be calculated based on Equation 1 below.

[0073] [Equation 1]

[0074]

[0075] (PT: Transmit power, GT: Gain of transmit antenna, GR: Gain of receive antenna, R: Distance, f: Frequency, PLF: Polarization loss factor)

[0076] Referring to [Equation 1], the received power can depend on the PLF. PLF is an indicator of power loss due to the difference in polarization characteristics between the transmitting and receiving antennas. PLF can be "1" when the polarization characteristics of the transmitting antenna match those of the receiving antenna. PLF can be "0" when the polarization characteristics of the transmitting and receiving antennas are completely mismatched. To improve communication efficiency, a correlation between the polarization characteristics of the transmitting and receiving antennas may be required.

[0077] Because circularly polarized signals have lower propagation loss than linearly polarized signals, they are suitable for long-distance communication. Since satellite 300 is located hundreds to tens of thousands of kilometers above the ground where electronic device 101 is located, the antenna of satellite 300 can have circular polarization characteristics to reduce signal loss. For example, the antenna of satellite 300 can be configured to radiate right-hand circularly polarized (RHCP) to improve the efficiency of satellite communication. When the antenna of electronic device 101 performing satellite communication has circular polarization characteristics, its satellite communication efficiency can be improved because it matches the polarization characteristics of the antenna of satellite 300.

[0078] As described above, the first antenna 210 and the second antenna 220 for cellular communication can have linear polarization characteristics, and the antenna of the satellite 300 can have circular polarization (e.g., RHCP) characteristics. According to [Equation 1], the satellite communication efficiency of the first antenna 210 and the second antenna 220 may be degraded due to the difference in polarization characteristics. The electronic device 101 may include at least one switching circuit 280 for adjusting the electrical path and at least one processor 240 configured to control the at least one switching circuit 280, such that the first antenna 210 and the second antenna 220 radiate with circular polarization (e.g., RHCP) to improve satellite communication performance. For example, the at least one processor 240 and the at least one switching circuit 280 may be disposed on a printed circuit board 201.

[0079] At least one processor 240 may be configured to control the operation of electronic device 101. Any function or operation described herein may be processed by a single processor or a combination of processors. A single processor or combination of processors is circuitry that performs processing and includes components such as an application processor (AP, e.g., a central processing unit (CPU)), a communication processor (CP, e.g., a modem), a graphics processing unit (GPU), a neural processing unit (NPU) (e.g., an artificial intelligence (AI) chip), a Wi-Fi chip, and Bluetooth. TM Circuits including chips, GPS chips, NFC chips, connectivity chips, sensor controllers, touch controllers, fingerprint sensor controllers, display driver integrated circuits (ICs), audio codec chips, Universal Serial Bus (USB) controllers, camera controllers, image processing ICs, microprocessor units (MPUs), system-on-a-chip (SoCs), and other ICs.

[0080] Figure 3 This is a simplified block diagram of an electronic device according to an exemplary embodiment.

[0081] refer to Figure 3 According to an exemplary embodiment, the electronic device 101 may include at least one processor 240, a memory 130, a first antenna 210, a second antenna 220, an RF transceiver 250, a phase shifter 260, a power branch circuit 270, and at least one switching circuit 280.

[0082] For example, at least one processor 240 may include an application processor (AP) (e.g., Figure 1 The main processor 121) and the communication processor (CP) (e.g., Figure 1 At least one of the coprocessors 123.

[0083] For example, at least one processor 240 can generate a baseband signal. At least one processor 240 can control the RF transceiver 250 to process the generated baseband signal. At least one processor 240 can control the RF transceiver 250 to transmit a transmission signal via a first antenna 210 and a second antenna 220. At least one processor 240 can control the RF transceiver 250 to transmit the transmission signal in a frequency band capable of communicating with external electronic devices. For example, the frequency band for transmitting the transmission signal could be a satellite communication band (e.g., approximately 1.6 GHz).

[0084] For example, at least one processor 240 may be configured to control at least one switching circuit 280. At least one processor 240 may be configured to control the electrical path between the RF transceiver 250 and the first antenna 210, and the electrical path between the RF transceiver 250 and the second antenna 220, by controlling at least one switching circuit 280. (See later...) Figure 4a and 4c The description refers to adjusting the electrical path by controlling at least one switching circuit 280.

[0085] For example, RF transceiver 250 may be implemented as a single chip (e.g., an RFIC chip) or as part of a single package. RF transceiver 250 may include a digital-to-analog converter (DAC) for converting digital signals to analog signals. RF transceiver 250 may include a mixer and an oscillator (e.g., a local oscillator (LO)) for up-conversion. RF transceiver 250 may convert baseband signals generated by at least one processor 240 into RF signals. RF transceiver 250 may include an analog-to-digital converter (ADC) for converting analog signals to digital signals. RF transceiver 250 may include a mixer and an oscillator for down-conversion. RF transceiver 250 may convert RF signals received from the first antenna 210 and the second antenna 220 into baseband signals that can be processed by at least one processor 240.

[0086] For example, memory 130 may store instructions executable by at least one processor 240. When executed by at least one processor 240, the instructions may cause electronic device 101 to perform operations (e.g., Figure 8 Operations and / or Figure 9a (Operation).

[0087] For example, phase shifter 260 can be configured to adjust the phase of a signal. For example, phase shifter 260 can be implemented as a circuit including passive elements such as capacitors, inductors, and / or resistors. However, it is not limited to this. Phase shifter 260 can be implemented as a circuit including active elements such as transistors and / or integrated circuits. For example, phase shifter 260 can create a phase difference between a signal before passing through phase shifter 260 and a signal after passing through phase shifter 260. For example, when a signal passes through phase shifter 260, the phase of the signal is delayed by phase shifter 260, thereby causing a phase difference. For example, the signal after passing through phase shifter 260 may have a phase difference of 90 degrees or 270 degrees compared to the signal before passing through phase shifter 260.

[0088] For example, the power branch circuit 270 can be a three-port passive component. For example, each of the three ports 271, 272, and 273 can be connected via an electrical path having a characteristic impedance of 50 ohms. For example, a signal input through port 271 can be distributed to have equal power and output to ports 272 and 273. For example, signals input to ports 272 and 273 can be combined into a single signal and output to port 271. The power branch circuit 270 can be referred to as a frequency divider, splitter, and / or coupler. For example, a transmit signal sent from the RF transceiver 250 can be distributed via the power branch circuit 270 and provided to each of the first antenna 210 and the second antenna 220. For example, a receive signal received from an external electronic device via the first antenna 210 and the second antenna 220 can be combined via the power branch circuit 270 and provided to the RF transceiver 250.

[0089] For example, phase shifter 260 can be electrically connected to second antenna 220. When phase shifter 260 is electrically connected to second antenna 220, both the signal supplied to and received from second antenna 220 can pass through phase shifter 260. Phase delay may occur when the signal passes through phase shifter 260. For example, phase shifter 260 can be electrically disconnected from first antenna 210. For example, both the signal supplied to and received from first antenna 210 may not pass through phase shifter 260.

[0090] For example, at least one switching circuit 280 may be configured to provide an electrical path between the RF transceiver 250 and the first antenna 210 (e.g., Figure 4a The first path P1 and Figure 4c The third path P3) and the electrical path between the RF transceiver 250 and the second antenna 220 (e.g., Figure 4a The second path P2 and Figure 4c(Fourth path P4). For example, at least one switching circuit 280 can be configured to selectively provide a first connection state or a second connection state by being controlled by at least one processor 240. Instructions stored in memory 130, when executed by at least one processor 240, can cause electronic device 101 to control at least one switching circuit 280. For example, at least one switching circuit 280 may include a first switching circuit 281, a second switching circuit 282, and a third switching circuit 283.

[0091] For example, at least one switching circuit 280 can be controlled to a first connected state to form an electrical path through the power branch circuit 270. The electrical path through the power branch circuit 270 can be referred to as a path in which the power branch circuit 270 is included in the electrical path between the RF transceiver 250 and the first antenna 210, and in the electrical path between the RF transceiver 250 and the second antenna 220. The electrical path through the power branch circuit 270 can cause the first antenna 210 and the second antenna 220 to radiate with circular polarization. For example, the first connected state can be referred to as a circular polarization mode. See below for further details. Figure 4a and Figure 4b The operation of the first antenna 210 and the second antenna 220 in the first connection state is described.

[0092] For example, at least one switching circuit 280 can be controlled to a second connection state to form an electrical path that bypasses the power branch circuit 270. This electrical path bypassing the power branch circuit 270 can be described as a path that does not include the power branch circuit 270 in the electrical path between the RF transceiver 250 and the first antenna 210, and also does not include the power branch circuit 270 in the electrical path between the RF transceiver 250 and the second antenna 220. This electrical path bypassing the power branch circuit 270 can cause the first antenna 210 and the second antenna 220 to radiate linearly polarized. For example, the second connection state can be described as a linear polarization mode or a diversity mode. See below for further details. Figure 4b The operation of the first antenna 210 and the second antenna 220 in the second connection state is described.

[0093] According to an embodiment, electronic device 101 can adjust the electrical path to improve satellite communication efficiency while performing satellite communication. For example, when electronic device 101 transmits a signal to satellite 300, at least one switching circuit 280 can be configured to selectively provide a first connection state or a second connection state. For example, when the satellite communication efficiency in the first connection state is higher than that in the second connection state, at least one processor 240 can be configured to control at least one switching circuit 280 to the first connection state. For example, when the satellite communication efficiency in the second connection state is higher than that in the first connection state, at least one processor 240 can be configured to control at least one switching circuit 280 to the second connection state.

[0094] Figure 4a The electrical path within the first connection state is shown. Figure 4b The polarization radiated from the first antenna and the second antenna is shown. Figure 4c The electrical path within the second connection state is shown.

[0095] refer to Figure 4a An electrical path through the power branch circuit 270 can be formed in the first connection state. For example, a first path P1 and a second path P2 can be formed in the first connection state.

[0096] For example, the first path P1 can be an electrical path between the RF transceiver 250 and the first antenna 210 in the first connected state. For example, the first path P1 can be an electrical path for electrically connecting the RF transceiver 250, the power branch circuit 270, and the first antenna 210. For example, in the first connected state, a transmit signal from the RF transceiver 250 to the first antenna 210 can be provided along the first path P1. The transmit signal can be provided to the first antenna 210 by being branched by the power branch circuit 270.

[0097] For example, the second path P2 can be an electrical path between the RF transceiver 250 and the second antenna 220 in the first connected state. For example, the second path P2 can be an electrical path for electrically connecting the RF transceiver 250, the power branch circuit 270, the phase shifter 260, and the second antenna 220. For example, in the second connected state, a transmit signal from the RF transceiver 250 to the second antenna 220 can be provided along the second path P2. The transmit signal can be provided to the second antenna 220 by being branched by the power branch circuit 270 and passing through the phase shifter 260.

[0098] For example, in the first connection state, the first antenna 210 and the second antenna 220 can be configured for circular polarization. The transmitted signal from the RF transceiver 250 can be provided to the first antenna 210 and the second antenna 220 by being branched by the power branching circuit 270. The phase of the transmitted signal branched by the power branching circuit 270 and provided to the second antenna 220 can be delayed by passing through the phase shifter 260. According to an exemplary embodiment, the electronic device 101 can achieve circular polarization by giving the feed structure a phase difference generated by the phase shifter 260. For example, the phase difference can be 90 degrees or 270 degrees, but is not limited thereto.

[0099] For example, in the first connection state, the first antenna 210 and the second antenna 220 can be configured to radiate circular polarization based on the difference between the phase of the signal before passing through the phase shifter 260 and the phase of the signal after passing through the phase shifter 260. Circular polarization can be formed by feeding two linearly polarized antennas that are orthogonal to each other and have a 90-degree phase difference.

[0100] Reference Figure 4b , Figure 4b 401 shows the first antenna in the first connection state (e.g., Figure 4a The polarization characteristics of the first antenna 210. For example, the polarization characteristics of the first antenna 210 can be linear polarization characteristics, which have a polarization perpendicular to the polarization of the first antenna 210 (e.g., without a phase shifter). Figure 4a The electric field vector E1 is the direction of advance of the radio wave D1 of the phase shifter 260. Figure 4b 402 indicates the direction of the electric field vector E1 when the electric field formed by the first antenna 210 is observed in the direction of travel D1 of the radio waves provided by the first antenna 210. The direction of the electric field vector E1 of the first antenna 210 can be perpendicular to the direction of travel D1 of the radio waves.

[0101] Figure 4b Figure 403 illustrates the polarization characteristics of the second antenna 220 in the first connection state. For example, the transmitted signal provided to the second antenna 220 may have a phase difference with the transmitted signal provided to the first antenna 210 via phase shifter 260. For example, the polarization characteristics of the second antenna 220 may be linear polarization characteristics having an electric field vector E2 parallel to the propagation direction D2 of the radio wave based on the transmitted signal via phase shifter 260. Figure 4b Figure 404 shows the direction of the electric field vector E2 when the electric field formed by the second antenna 220 is observed in the direction of travel of the radio wave provided by the second antenna 220. The direction of the electric field vector E2 of the second antenna 220 can be horizontal with the direction of travel of the radio wave D2.

[0102] Figure 4b405 indicates the polarization characteristics of the first antenna 210 and the second antenna 220 formed by synthesizing the polarization characteristics of the first antenna 210 and the second antenna 220 in the first connection state. For example, the polarization characteristics of the first antenna 210 and the second antenna 220 may be circular polarization characteristics formed by synthesizing two linear polarizations that are perpendicular to each other. Figure 4b 406 indicates the direction of the electric field vector E3 when the electric field formed by the first antenna 210 and the second antenna 220 is observed in the direction of travel D3 of the radio waves provided by the first antenna 210 and the second antenna 220. The direction of the electric field vector E3 formed by the first antenna 210 and the second antenna 220 can be rotated relative to the direction of travel D3 of the radio waves. For example, circular polarization can be RHCP. However, it is not limited to this. For example, depending on the polarization characteristics of the satellite 300 with which the electronic device 101 wants to communicate, the circular polarization can be left-hand circular polarization (LHCP).

[0103] As described above, in the first connected state, the first antenna 210 and the second antenna 220 can be configured to radiate circularly polarized via the power branch circuit 270 and the phase shifter 260. For example, when a phase difference is formed based on the difference in the length of the electrical path, space may be required to form the electrical path. Since the internal space of the electronic device 101 is limited, it may be difficult to achieve circular polarization by forming a phase difference based on the difference in the length of the electrical path. According to an embodiment, the electronic device 101 can achieve the circular polarization characteristics of the first antenna 210 and the second antenna 220 for communication diversity by using at least one switching circuit 280 to adjust the electrical path and using the power branch circuit 270 and the phase shifter 260.

[0104] Return to reference Figure 4a At least one switching circuit 280 can be configured to selectively provide a first connection state or a second connection state. At least one switching circuit 280 can be controlled by at least one processor 240. Instructions stored in memory 130, when executed by at least one processor 240, can cause electronic device 101 to control at least one switching circuit 280 to provide a first connection state for at least one switching circuit 280. For example, at least one switching circuit 280 may include a first switching circuit 281, a second switching circuit 282, and a third switching circuit 283.

[0105] For example, the first switching circuit 281, the second switching circuit 282, and the third switching circuit 283 may be single-pole double-throw (SPDT) switching circuits. For example, the first switching circuit 281, the second switching circuit 282, and the third switching circuit 283 may include three ports.

[0106] For example, the first switching circuit 281 may be configured to electrically connect the first antenna 210 or the power branch circuit 270 to the RF transceiver. For example, the first switching circuit 281 may include a first port 281a electrically connected to the RF transceiver, a second port 281b electrically connected to a fourth port 282a of the second switching circuit 282, and a third port 281c electrically connected to the power branch circuit 270.

[0107] For example, the second switching circuit 282 may be configured to electrically connect the first switching circuit 281 or the power branch circuit 270 to the first antenna 210. For example, the second switching circuit 282 may include a fourth port 282a electrically connected to a second port 281b of the first switching circuit 281, a fifth port 282b electrically connected to the power branch circuit 270, and a sixth port 282c electrically connected to the first antenna 210.

[0108] For example, the third switching circuit 283 may be configured to electrically connect the RF transceiver 250 or the power branch circuit 270 to the second antenna 220. For example, the third switching circuit 283 may include a seventh port 283a electrically connected to the power branch circuit 270, an eighth port 283b electrically connected to the RF transceiver 250, and a ninth port 283c electrically connected to the second antenna 220.

[0109] Figure 4a The first switch circuit 281, the second switch circuit 282, and the third switch circuit 283 shown in the diagram indicate a first connection state. In the first connection state, a first path P1 for electrically connecting the RF transceiver 250, the power branch circuit 270, and the first antenna 210, and a second path P2 for electrically connecting the RF transceiver 250, the power branch circuit 270, and the phase shifter 260 and the second antenna 220 can be formed by at least one switch circuit 280.

[0110] For example, at least one processor 240 may be configured to control the switching circuit to provide a first connection state based on connecting the RF transceiver 250 to the power branch circuit 270 via a first switching circuit 281, connecting the power branch circuit 270 to the first antenna 210 via a second switching circuit 282, and connecting the power branch circuit 270 to the second antenna 220 via a third switching circuit 283.

[0111] For example, in the first connected state, at least one processor 240 can control the first switching circuit 281, such that the first port 281a and the third port 281c of the first switching circuit 281 are connected. For example, in the first connected state, at least one processor 240 can control the second switching circuit 282, such that the fifth port 282b and the sixth port 282c of the second switching circuit 282 are connected. For example, in the first connected state, at least one processor 240 can control the third switching circuit 283, such that the seventh port 283a and the ninth port 283c of the third switching circuit 283 are connected. For example, in the first connected state, a first path P1 passing through the power branch circuit 270 can be formed through the first switching circuit 281 and the second switching circuit 282. For example, in the first connected state, a second path P2 passing through the power branch circuit 270 can be formed through the first switching circuit 281 and the third switching circuit 283.

[0112] According to an embodiment, in the first connection state, the first antenna 210 and the second antenna 220 can be configured for radial circular polarization. As described above, the transmission signal sent from the RF transceiver can be provided to the first antenna 210 along the first path P1 and to the second antenna 220 along the second path P2. Since the phase shifter 260 is disposed on the second path P2, the phase of the transmission signal through the first path P1 and the phase of the transmission signal through the second path P2 can have a 90-degree difference. The first antenna 210 and the second antenna 220 can be configured for radial circular polarization based on the phase difference.

[0113] For example, the antenna of satellite 300 can have circular polarization characteristics. According to [Equation 1], the received power can be determined based on the polarization loss coefficient according to the difference in polarization characteristics between the transmitting antenna and the receiving antenna. Since the first antenna 210 and the second antenna 220 can have circular polarization characteristics in the first connection state, the satellite communication efficiency of the first antenna 210 and the second antenna 220 can be improved. According to an exemplary embodiment, electronic device 101 can improve satellite communication efficiency by using the first antenna 210 and the second antenna 220, which are orthogonal to each other, to radiate circular polarization, without having a separate antenna for satellite communication.

[0114] Reference Figure 4c In the second connection state, an electrical path bypassing the power branch circuit 270 can be formed. For example, in the second connection state, a third path P3 and a fourth path P4 can be formed. Instructions stored in memory 130, when executed by at least one processor 240, can cause electronic device 101 to control at least one switching circuit 280 to provide the second connection state of at least one switching circuit 280.

[0115] For example, the third path P3 could be an electrical path between the RF transceiver 250 and the first antenna 210 in the second connection state. For example, the third path P3 could be a path for electrically connecting the RF transceiver 250 and the first antenna 210 by bypassing the power branch circuit 270. For example, in the second connection state, a transmission signal from the RF transceiver 250 to the first antenna 210 could be provided along the third path P3. The transmission signal could be provided to the first antenna 210 by bypassing the power branch circuit 270.

[0116] For example, in the second connection state, the fourth path P4 can be an electrical path between the RF transceiver 250 and the second antenna 220. For example, the fourth path P4 can be an electrical path for electrically connecting the RF transceiver 250, the phase shifter 260, and the second antenna 220 by bypassing the power branch circuit 270. For example, in the second connection state, a transmission signal from the RF transceiver 250 to the second antenna 220 can be provided along the fourth path P4. The transmission signal can be provided to the second antenna 220 by bypassing the power branch circuit 270 and passing through the phase shifter 260.

[0117] For example, in the second connection state, the first antenna 210 and the second antenna 220 can be configured for linear radiation polarization. For example, the third path P3 can be independent of the fourth path P4. For example, in the second connection state, the first antenna 210 and the second antenna 220 can be used for communication diversity. For example, electronic device 101 can use the first antenna 210 and the second antenna 220 to send another signal to transmit diversity. For example, electronic device can use the first antenna 210 and the second antenna 220 to receive a signal according to receive diversity.

[0118] Figure 4c The first switch circuit 281, the second switch circuit 282, and the third switch circuit 283 shown in the diagram indicate a second connection state. In the second connection state, a third path P3 for electrically connecting the RF transceiver 250 and the first antenna 210 and a fourth path P4 for electrically connecting the RF transceiver 250, the phase shifter 260, and the second antenna 220 can be formed by at least one switch circuit 280.

[0119] For example, at least one processor 240 may be configured to control the switching circuits to provide a second connection state based on the connection of the RF transceiver 250 via the first switching circuit 281 and the second switching circuit 282, the connection of the first switching circuit 281 and the first antenna 210 via the second switching circuit 282, and the connection of the second antenna 220 and the RF transceiver 250 via the third switching circuit 283.

[0120] For example, in the second connection state, at least one processor 240 can control the first switching circuit 281, such that the first port 281a and the second port 281b of the first switching circuit 281 are connected. For example, in the first connection state, at least one processor 240 can control the second switching circuit 282, such that the fourth port 282a and the sixth port 282c of the second switching circuit 282 are connected. For example, in the second connection state, at least one processor 240 can control the third switching circuit 283, such that the eighth port 283b and the ninth port 283c of the third switching circuit 283 are connected. For example, in the second connection state, a third path P3 bypassing the power branch circuit 270 can be formed through the first switching circuit 281 and the second switching circuit 282. For example, in the second connection state, a fourth path P4 bypassing the power branch circuit 270 can be formed through the third switching circuit 283.

[0121] According to an embodiment, in the second connection state, the first antenna 210 and the second antenna 220 can be configured to radiate linearly polarized. As described above, the third path P3 can be independent of the fourth path P4. The electronic device 101 can be configured to communicate with an external electronic device by radiating signals via the first antenna 210 and the second antenna 220 based on diversity techniques (e.g., time diversity).

[0122] Figure 5a and Figure 5b The positions of the first and second antennas of an electronic device according to an exemplary embodiment are schematically shown. Figure 6 It is a graph showing the signals input to the first and second antennas relative to the time domain.

[0123] For example, the polarization characteristics of the first antenna 210 and the second antenna 220 can be RHCP. RHCP is circular polarization, in which the rotational trajectory in a circular plane perpendicular to the direction of radio wave propagation is counterclockwise.

[0124] Reference Figure 5aThe first antenna 210 and the second antenna 220 may be perpendicular to each other to radiate circularly polarized radiation. For example, the electronic device 101 may include at least one display 290. The at least one display 290 may define at least a portion of the front surface of the electronic device 101. The first antenna 210 and the second antenna 220 are disposed on a plane substantially the same as the at least one display 290 (e.g., the xy plane) and may be perpendicular to each other in that plane. In various embodiments of this disclosure, for ease of description, the x-axis direction is defined as the horizontal direction and the y-axis direction is defined as the vertical direction. In the following description, relative terms such as horizontal and vertical may be used to describe the relative positions between the first antenna 210 and the second antenna 220. For example, when the electronic device 101 shown in the figures is rotated 90 degrees, horizontal and vertical may be interchanged.

[0125] For example, the first antenna 210 and the second antenna 220 can transmit and / or receive signals in a specified frequency band. For example, the electrical length of the first antenna 210 and the second antenna 220 can be a length corresponding to the frequency characteristics (e.g., resonant frequency) of the signal to be transmitted and / or received through the first antenna 210 and the second antenna 220. For example, when the wavelength corresponding to the resonant frequency of the signal to be transmitted and / or received through the first antenna 210 and the second antenna 220 is λ, the electrical length of the first antenna 210 and the second antenna 220 can be approximately 1 / 4λ to approximately 1 / 2λ. For example, when the resonant frequency of the signal is approximately 1.6 GHz, the wavelength corresponding to the resonant frequency can be approximately 185 mm, and the electrical length of the first antenna 210 and the second antenna 220 can be approximately 46 mm to 93 mm.

[0126] like Figure 5a As shown, the first antenna 210 can be positioned in a substantially horizontal direction (e.g., the x-axis direction), and the second antenna 220 can be positioned in a substantially vertical direction (e.g., the y-axis direction).

[0127] For example, when the first antenna 210 is formed at least partially along the first edge portion 231, the second antenna 220 may be formed at least partially along the second edge portion 232 perpendicular to the first edge portion 231. However, it is not limited to this. For example, when the first antenna 210 is formed at least partially along the third edge portion 233, the second antenna 220 may be formed at least partially along the second edge portion 232 perpendicular to the third edge portion 233.

[0128] For example, the distance between the first antenna 210 and the second antenna 220 can be determined based on the frequency of the signal to be transmitted and / or received through the first antenna 210 and the second antenna 220. For example, when the wavelength corresponding to the operating frequency of the first antenna 210 and the second antenna 220 (e.g., about 1.6 GHz) is λ, the distance between the first antenna 210 and the second antenna 220 can be less than or equal to about 1 / 2λ. When the combined radiation pattern of the first antenna 210 and the radiation pattern of the second antenna 220 are circularly polarized, the gain may decrease due to the appearance of grating lobes if the distance between the first antenna 210 and the second antenna 220 is greater than about 1 / 2λ. To suppress the appearance of grating lobes, the distance between the first antenna 210 and the second antenna 220 can be less than or equal to about 1 / 2 of the wavelength corresponding to the operating frequency.

[0129] For example, the second antenna 220 can be positioned at a first location 501, including the corner of the frame 230, or at a second location 502, spaced apart from the corner of the frame 230. For example, even when the second antenna 220 is located at the second location 502, which is relatively far from the first antenna 210, the distance between the first antenna 210 and the second antenna 220 can be less than or equal to about half the wavelength corresponding to the operating frequency (e.g., about 1.6 GHz) to suppress the appearance of grating lobes.

[0130] For example, in the first connected state, the same signal (e.g., -3dB) can be transmitted from the RF transceiver (e.g., Figure 3 The RF transceiver 250 is input to each of the first antenna 210 and the second antenna 220 so that the first antenna 210 and the second antenna 220 radiate RHCP. As described above, the signal input to the second antenna 220 can have a phase difference relative to the signal input to the first antenna 210 via the phase shifter 260. When the electronic device 101 has Figure 5a In the arrangement shown, the signal input to the second antenna 220 can have a +90-degree phase difference based on the signal input to the first antenna 210 in order to achieve RHCP.

[0131] refer to Figure 6 Compared to signals that do not pass through phase shifter 260, signals that pass through phase shifter (e.g., Figure 3 The signal from the phase shifter 260 may be delayed. For example, in a phase shifter with... Figure 5a In the electronic device 101 with the shown structure, the first graph 510 can be a graph of the signal input to the first antenna 210, and the second graph 520 can be a graph of the signal input to the second antenna 220. Figure 6 In the diagram, the x-axis represents time (in nanoseconds), and the y-axis represents watts (W). 1 / 2 .

[0132] Since the phase of the signal input to the second antenna 220 can be delayed as it passes through the phase shifter 260, it can have a phase difference of +90 degrees compared to the signal input to the first antenna 210. For example, since the signal input to the second antenna 220, which is included in at least a portion of the edge defining one side (e.g., the +x direction), has a phase difference of +90 degrees compared to the signal input to the first antenna 210, which is included in at least a portion of the edge defining the upper part (e.g., the +y direction), RHCP can be achieved.

[0133] refer to Figure 5b When the first antenna 210 is formed at least partially along the first edge portion 231, the second antenna 220 can be formed at least partially along the fourth edge portion 234 perpendicular to the first edge portion 231. Figure 5b As shown, the first antenna 210 can be positioned in a substantially horizontal direction (e.g., the x-axis direction), and the second antenna 220 can be positioned in a substantially vertical direction (e.g., the y-axis direction). For example, the second antenna 220 can be positioned at a third location 503 including the corner of the frame 230, or at a fourth location 504 spaced apart from the corner of the frame 230. For example, even when the second antenna 220 is located at the fourth location 504, which is relatively far from the first antenna 210, the distance between the first antenna 210 and the second antenna 220 can be less than or equal to about half the wavelength corresponding to the operating frequency (e.g., about 1.6 GHz) to suppress the appearance of grating lobes.

[0134] When electronic device 101 has Figure 5b In the illustrated arrangement, the signal input to the second antenna 220 can achieve RHCP based on a phase difference of +270 degrees (or -90 degrees) compared to the signal input to the first antenna 210. Since the phase of the signal input to the second antenna 220 can be delayed as it passes through the phase shifter 260, it can have a phase difference of +270 degrees compared to the signal input to the first antenna 210. For example, RHCP can be achieved because the signal input to the second antenna 220, which is included in at least a portion of the edge defining the other side (e.g., the -x direction), has a phase difference of +270 degrees compared to the signal input to the first antenna 210, which is included in at least a portion of the edge defining the upper part (e.g., the +y direction).

[0135] Figure 7a The gain is shown based on the positions of the first and second antennas in the first connection state. Figure 7b The axial ratio is shown based on the positions of the first and second antennas in the first connection state.

[0136] For example, Figure 7a The polar coordinate system shown indicates the rotation of an electronic device with a fixed orientation (e.g., Figure 2 When measuring the azimuth angle of the first antenna (e.g., electronic device 101), Figure 2 The first antenna 210) and the second antenna (e.g., Figure 2 The gain of the second antenna 220. For example, the distance from the pole indicates the gain, and the angle relative to the polar axis indicates the azimuth. For example, a 0-degree angle indicates the direction in which the rear surface (e.g., the rear cover) of the electronic device 101 faces. For example, a 90-degree angle indicates the bottom of the electronic device 101 (e.g., the bottom surface). Figure 2 The third edge portion (e.g., Figure 2 The direction in which the third edge portion 233 faces. For example, a 180-degree angle indicates the front surface of the electronic device 101 (e.g., Figure 5a The orientation of at least one display 290. For example, a 270-degree angle indicates the upper part of the electronic device 101 (e.g., Figure 2 The direction that the first edge portion 231 faces.

[0137] Figure 7a The radiation pattern shown indicates the gain pattern of a circularly polarized signal in a specified frequency band (e.g., about 1.6 GHz) relative to the azimuth angle of an electronic device 101 with a fixed elevation angle.

[0138] Figure 7a 701 shows when the second line 220 is set Figure 5a The first position (e.g., in the electronic device 101 with the structure shown) Figure 5a The circular polarization gain of the first antenna 210 and the second antenna 220 at the first position 501. Figure 7a 702 shows when the second line 220 is set Figure 5a The second position (e.g., in the electronic device 101 with the structure shown) Figure 5a The circular polarization gain of the first antenna 210 and the second antenna 220 at the second position 502). Figure 7a 703 shows that when the first antenna 210 is set Figure 5b The third position (e.g., in the electronic device 101 with the structure shown) Figure 5b The circular polarization gain of the first antenna 210 and the second antenna 220 at the third position 503. Figure 7a 704 shows that when the first antenna 210 is set... Figure 5b The fourth position (e.g., in the electronic device 101 with the structure shown) Figure 5bThe circular polarization gain of the first antenna 210 and the second antenna 220 at the fourth position 504.

[0139] Reference Figure 7a The direction of the main lobe of the radiation pattern and the gain of the radiation pattern can vary depending on the positions of the first antenna 210 and the second antenna 220, but the first antenna 210 and the second antenna 220 can be substantially in front of the electronic device 101 (e.g., in the direction in which at least one display 290 is facing) with circular polarization. Even when the positions of the first antenna 210 and the second antenna 220 change, the gain of the circular polarization is sufficient to perform satellite communication.

[0140] Figure 7b The axial ratio shown indicates the axial ratio of the circular polarization of the first antenna 210 and the second antenna 220 relative to the azimuth angle with respect to a specified frequency band (e.g., approximately 1.6 GHz) of an electronic device 101 with a fixed elevation angle. The axial ratio can indicate the ratio of the horizontal radiation component to the vertical radiation component in the circular polarization radiated by the first antenna 210 and the second antenna 220. When the axial ratio is closer to 0 dB, the magnitudes of the vertical and horizontal radiation components are similar, thus indicating near-circular polarization.

[0141] For example, Figure 7b The polar coordinate system shown indicates the rotation of an electronic device with a fixed orientation (e.g., Figure 2 While measuring the azimuth angle of the electronic device 101, the first antenna (e.g., Figure 2 The first antenna 210) and the second antenna (e.g., Figure 2 The axial ratio of the circular polarization of the second antenna 220 is the result. For example, the distance from the pole represents the axial ratio, and the angle relative to the polar axis represents the azimuth angle. For example, a 0-degree angle indicates the direction in which the rear surface (e.g., the rear cover) of the electronic device 101 faces. For example, a 90-degree angle indicates the bottom of the electronic device 101 (e.g., the bottom surface). Figure 2 The direction in which the third edge portion 233 faces. For example, a 180-degree angle indicates the front surface of the electronic device 101 (e.g., Figure 5a The orientation of at least one display 290. For example, a 270-degree angle indicates the upper part of the electronic device 101 (e.g., Figure 2 The direction that the first edge portion 231 faces.

[0142] Figure 7b 705 shows when the second line 220 is set Figure 5a The first position (e.g., in the electronic device 101 with the structure shown) Figure 5a The axial ratio of the circular polarization of the first antenna 210 and the second antenna 220 at the first position 501). Figure 7b706 shows when the second line 220 is set Figure 5a The second position (e.g., in the electronic device 101 with the structure shown) Figure 5a The axial ratio of the circular polarization of the first antenna 210 and the second antenna 220 at the second position 502). Figure 7b 707 shows that when the first antenna 210 is set... Figure 5b The third position (e.g., in the electronic device 101 with the structure shown) Figure 5a The axial ratio of the circular polarization of the first antenna 210 and the second antenna 220 at the third position 503. Figure 7b 708 shows that when the first antenna 210 is set Figure 5b The fourth position (e.g., in the electronic device 101 with the structure shown) Figure 5a The axial ratio of the circular polarization of the first antenna 210 and the second antenna 220 at the fourth position 504.

[0143] refer to Figure 7b Although the axial ratio of circular polarization can vary depending on the positions of the first antenna 210 and the second antenna 220, the axial ratio in the direction of the main lobe of circular polarization (e.g., the direction in which at least one display 290 faces) is less than or equal to 5 dB. For example, even when the positions of the first antenna 210 and the second antenna 220 change, the electronic device 101 can still achieve circular polarization using the first antenna 210 and the second antenna 220 that are orthogonal to each other. According to the embodiment, the satellite communication efficiency of the electronic device 101 that implements circular polarization can be improved.

[0144] Figure 8 This is a flowchart illustrating the operation of at least one switching circuit when an electronic device performs satellite communication according to an exemplary embodiment.

[0145] Figure 8 The operation shown can be when stored in memory (e.g., Figure 3 The instructions in the memory 130) are processed by at least one processor (e.g., Figure 3 The operation caused by the electronic device 101 is executed by at least one processor 240.

[0146] Reference Figure 8 In operation 801, at least one processor 240 may be based on the method for sending data to an external electronic device (e.g., Figure 2 The application executes signals transmitted by the satellite 300 to control the RF transceiver (e.g., Figure 3 The RF transceiver 250 sends transmission signals to external electronic devices.

[0147] For example, electronic devices (e.g., Figure 2Electronic device 101 can be configured to perform satellite communications. For example, electronic device 101 can be configured to transmit and / or receive signals in a satellite communication band (e.g., approximately 1.6 GHz) used in non-terrestrial networks, using only satellite networks and not cellular networks. For example, in areas where no cellular network is provided, electronic device 101 can perform satellite communications via signals in the satellite communication band.

[0148] For example, satellite communication can be performed based on the execution of an application for transmitting signals to an external electronic device (e.g., satellite 300). For example, electronic device 101 may include an application for transmitting an SOS signal (e.g., an SOS message) requesting emergency assistance using satellite 300 in areas where no cellular network is provided. For example, the SOS signal may include location information of electronic device 101 (e.g., longitude, latitude) and / or medical information relevant to the user. Based on the execution of the application, at least one processor 240 can control RF transceiver 250 to transmit transmission signals to satellite 300. RF transceiver 250 can transmit signals via a first antenna (e.g., Figure 2 The first antenna 210) and the second antenna (e.g., Figure 2 The second antenna 220 transmits signals in the satellite communication band.

[0149] In operation 803, at least one processor 240 can identify a first reception quality and a second reception quality.

[0150] For example, at least one processor 240 can control at least one switching circuit 280, such that at least one switching circuit (e.g., Figure 3 At least one switching circuit 280 provides a first connection state or a second connection state. For example, the first reception quality can be referred to as the reception quality of a first signal received through the first antenna 210 and the second antenna 220 in the first connection state. For example, the second reception quality can be referred to as the reception quality of a second signal received through the first antenna 210 and the second antenna 220 in the second connection state.

[0151] For example, the signal quality in various embodiments of this disclosure can be at least one of the following: Reference Signal Received Power (RSRP), Beam Reference Signal Received Power (BRSRP), Reference Signal Received Quality (RSRQ), Received Signal Strength Indicator (RSSI), Signal-to-Interference and Noise Ratio (SINR), Carrier-to-Interference and Noise Ratio (CINR), Signal-to-Noise Ratio (SNR), Error Vector Magnitude (EVM), Bit Error Rate (BER), and Block Error Rate (BLER). Besides the examples above, other terms or other metrics indicating channel quality with equivalent technical meanings may obviously be used. In the following, in this disclosure, high signal quality means a large signal quality value related to signal size or a small signal quality value related to error rate. Higher signal quality can mean a smooth wireless communication environment. Additionally, optimal beam can refer to the beam with the highest signal quality among beams. For example, reception quality can be identified based on the Received Signal Strength Indicator (RSSI) value, which indicates the strength of the received signal of a radio wave. For example, first reception quality may include the RSSI value of a first signal, and second reception quality may include the RSSI value of a second signal. However, this is not a limitation.

[0152] For example, in operation 803, at least one processor 240 can control at least one switching circuit 280 to a first connected state and identify the RSSI value of a first signal. For example, at least one processor 240 can change at least one switching circuit 280 from the first connected state to a second connected state and identify the RSSI value of a second signal.

[0153] For example, in operation 805, at least one processor 240 can control at least one switching circuit 280 to a first connection state or a second connection state based on a first reception quality and a second reception quality.

[0154] For example, when communicating with an external electronic device (e.g., satellite 300), at least one processor 240 can communicate with the external electronic device based on a high reception quality state between a first connection state and a second connection state. For example, at least one processor 240 can compare the first reception quality with the second reception quality. For example, when the first reception quality is higher than the second reception quality, at least one processor 240 can control at least one switching circuit 280 to the first connection state. For example, when the second reception quality is higher than the first reception quality, at least one processor 240 can control at least one switching circuit 280 to the second connection state.

[0155] For example, at least one processor 240 can compare the RSSI value of the first signal with the RSSI value of the second signal. For example, when the RSSI value of the first signal is greater than the RSSI value of the second signal, at least one processor 240 can control at least one switching circuit 280 to a first connection state. For example, when the RSSI value of the second signal is greater than the RSSI value of the first signal, at least one processor 240 can control at least one switching circuit 280 to a second connection state. When the electronic device 101 communicates with an external electronic device, the electronic device 101 can communicate with the external electronic device with higher communication quality, thereby improving communication efficiency. For example, when the electronic device 101 performs satellite communication, the electronic device 101 can identify the higher connection state between the first and second connection states and perform satellite communication based on the identified connection state.

[0156] Figure 9a This is a flowchart illustrating the operation of an electronic device communicating with an external electronic device according to an exemplary embodiment. Figure 9b and Figure 9c A visual object displayed via a display of an electronic device is shown according to an exemplary embodiment.

[0157] For example, Figure 9a The operation shown can be described as the operation of electronic device 101 performing an emergency rescue request in an area where no cellular network is provided. Figure 9a The operation shown can be when stored in memory (e.g., Figure 3 The instructions in the memory 130) are processed by at least one processor (e.g., Figure 3 The operation caused by the electronic device 101 is executed by at least one processor 240.

[0158] refer to Figure 9a In operation 901, at least one processor 240 can send signals to an external electronic device.

[0159] For example, external electronic equipment could be a satellite (e.g., Figure 2 (e.g., satellite 300). For example, at least one processor 240 can control an RF transceiver (e.g., satellite 300) based on the execution of an application for transmitting signals to an external electronic device (e.g., satellite 300). Figure 3 The RF transceiver 250 transmits transmission signals to external electronic devices. For example, the application may include an application for sending an SOS signal (e.g., an SOS message) requesting emergency assistance using satellite communication. Operation 901 may be referred to as... Figure 8 Operation 801.

[0160] In operation 903, at least one processor 240 can power at least one switching circuit (e.g., Figure 3At least one switching circuit 280) controls the first connection state.

[0161] For example, at least one processor 240 may control at least one switching circuit 280 to a first connected state based on transmitting a signal to satellite 300. For example, at least one processor 240 may identify signal transmission to external electronic devices based on the execution of an application. For example, at least one processor 240 may identify the execution of satellite communication based on the execution of an application.

[0162] When transmitting signals to satellite 300, at least one processor 240 can improve satellite communication efficiency by controlling at least one switching circuit 280 to a first connected state. As described above, in the first connected state, the first antenna 210 and the second antenna 220 can be configured to radiate circularly polarized. For example, circular polarization can be RHCP. Since the first antenna 210 and the second antenna 220 are radiating circularly polarized in the first connected state, the polarization characteristics of the first antenna 210 and the second antenna 220 can correspond to the polarization characteristics of the antenna of satellite 300. When performing satellite communication, the polarization characteristics of the first antenna 210 and the second antenna 220 can correspond to the polarization characteristics of the antenna of satellite 300, thereby improving communication efficiency.

[0163] For example, at least one processor 240 can identify the position of satellite 300. For example, electronic device 101 may include a memory storing information about the orbit of satellite 300. At least one processor 240 can identify the position of satellite 300 at a timing point during satellite communication based on the orbital information of satellite 300 stored in the memory. At least one processor 240 can, based on the identified position of satellite 300, display the information via at least one display (e.g., [display]). Figure 9b At least one display 290 shows a visual object of the orientation of the first antenna 210 and the second antenna 220 of the guiding electronic device 101 toward the satellite 300. For example, this orientation may be referred to as the orientation in which the electronic device 101 positions the first antenna 210 and the second antenna 220 such that the electromagnetic waves formed by the first antenna 210 and the second antenna 220 are directed toward the satellite 300.

[0164] refer to Figure 9b The electronic device 101 may include at least one display 290. For example, the electronic device 101 may include at least one display 290 that defines at least a portion of the front surface of the electronic device 101.

[0165] For example, at least one processor 240 can identify the position of satellite 300 based on the execution of an application used to send an SOS message to satellite 300. At least one processor 240 can display a first visual object 910 via at least one display 290 to guide the orientation of electronic device 101, wherein the first antenna 210 and the second antenna 220 are facing satellite 300. For example, the first visual object 910 may include text 914, such as 'Send a message, move your phone along the satellite' and / or 'Send a new message, move your phone along satellite 300'. For example, the first visual object 910 may include an image representing satellite 300 and an image 912 indicating the orientation of satellite 300. However, this is not a limitation. A user can change the orientation of electronic device 101 via the first visual object 910 so that the first antenna 210 and the second antenna 220 are facing satellite 300. When the first antenna 210 and the second antenna 220 send signals to satellite 300 in an orientation facing satellite 300, satellite communication efficiency is improved, thus increasing the success rate of SOS message transmission. Figure 9a While performing operations 901, 903 and / or 905 as shown, the first visual object 910 described above can be displayed on at least one display 290.

[0166] Return to reference Figure 9a In operation 905, at least one processor 240 can determine whether the transmission of a signal (e.g., an SOS message) to an external electronic device has been successful. For example, in operation 905, if the signal transmission failure is detected, operation 901 can be executed again. For example, in operation 905, if the signal transmission is detected as successful, operation 907 can be executed.

[0167] In operation 907, at least one processor 240 can identify the first reception quality and the second reception quality.

[0168] For example, at least one processor 240 can identify the first reception quality of the first signal received via the first antenna 210 and the second antenna 220 in the first connected state based on the transmission of the identification signal. For example, in operation 903, since at least one switching circuit 280 is controlled to the first connected state, at least one processor 240 can identify the first reception quality by maintaining the first connected state. For example, the first reception quality can be referred to as the first RSSI value of the first signal.

[0169] For example, at least one processor 240 can control at least one switch to a second connection state and identify a second reception quality of the second signal received via the first antenna 210 and the second antenna 220 in the second connection state. For example, at least one processor 240 can change at least one switch circuit 280 from a first connection state to a second connection state and identify a second reception quality in the second connection state. For example, the second reception quality may be referred to as a second RSSI value of the second signal.

[0170] In operation 909, at least one processor 240 can compare a first reception quality and a second reception quality. For example, at least one processor 240 can identify whether the first reception quality is higher than the second reception quality.

[0171] For example, a response signal from satellite 300 to a signal (e.g., an SOS message) sent to satellite 300 can be received. For example, the signal sent to satellite 300 may include location information of electronic device 101 (e.g., latitude, longitude) and / or medical information related to the user. Satellite 300 may receive the signal including this information and send a response signal and a ringing alarm signal to electronic device 101 to notify of the reception information (e.g., reception timing) for the response signal. To receive the response signal sent from satellite 300, at least one processor 240 may be configured to identify a higher-quality connection state between a first connection state and a second connection state.

[0172] For example, at least one processor 240 can identify a connection state indicating higher reception quality by comparing a first reception quality with a second reception quality. For example, if the first RSSI value is greater than the second RSSI value, the first connection state can be referred to as a connection state indicating higher reception quality than the second connection state because the strength of the received signal in the first connection state is higher than the strength of the received signal in the second connection state. Similarly, if the second RSSI value is greater than the first RSSI value, the second connection state can be referred to as a connection state indicating higher reception quality than the first connection state because the strength of the received signal in the second connection state is greater than the strength of the received signal in the first connection state.

[0173] For example, in operation 909, when it is identified that the first reception quality is higher than the second reception quality, operation 911 can be executed. For example, in operation 909, when it is identified that the second reception quality is higher than the first reception quality, operation 913 can be executed.

[0174] In operation 911, at least one processor 240 can control at least one switching circuit 280 to a first connected state.

[0175] For example, if the first reception quality is higher than the second reception quality, the satellite communication efficiency in the first connection state can be higher than that in the second connection state. At least one processor 240 can control at least one switching circuit 280 to be in the first connection state in order to receive a response signal from the satellite 300. Since at least one switching circuit 280 provides the first connection state, the success rate of receiving response signals and / or ringing alarm signals from the satellite 300 can be improved.

[0176] In operation 913, at least one processor 240 can control at least one switching circuit 280 to a second connection state.

[0177] For example, if the second reception quality is higher than the first reception quality, the satellite communication efficiency in the second connection state can be higher than that in the first connection state. At least one processor 240 can control at least one switching circuit 280 to be in the second connection state to receive a response signal from the satellite 300. When at least one switching circuit 280 provides the second connection state, the success rate of receiving response signals and / or ringing alarm signals from the satellite 300 can be improved. For example, in the second connection state, the electronic device 101 can use the first antenna 210 and the second antenna 220 to transmit another signal for transmit diversity. For example, in the second connection state, the electronic device can use the first antenna 210 and the second antenna 220 to receive signals according to receive diversity.

[0178] In operation 915, at least one processor 240 can identify whether a signal has been received from an external electronic device.

[0179] For example, in Operation 915, based on the recognition of a signal received from an external electronic device, the operation to execute an emergency rescue request can be terminated.

[0180] For example, at least one processor 240 can recognize the reception of response signals and / or ringing alarm signals from satellite 300 via first antenna 210 and second antenna 220. For example, if no signal is recognized from satellite 300, operation 907 can be performed again. At least one processor 240 can be configured to recognize a connection state with higher reception quality provided by at least one switching circuit 280 when no signal is recognized from satellite 300, and control at least one switching circuit 280 to the recognized state.

[0181] Reference Figure 9cThe electronic device 101 can identify the position of the satellite 300 to receive response signals and / or ringing alarm signals from the satellite 300. At least one processor 240 can display a second visual object 920 on at least one display 290 based on the identified position of the satellite 300 to guide the orientation of the electronic device 101, wherein the first antenna 210 and the second antenna 220 are facing the satellite 300.

[0182] For example, the second visual object 920 may include text 921, such as “To receive new messages, move your phone along the satellite” and / or “To receive new messages, move your phone along satellite 300”. For example, the second visual object 920 may include an image representing satellite 300 and an image 922 indicating the direction satellite 300 is facing. However, it is not limited to this. The user can use the second visual object 920 to change the orientation of the electronic device 101 so that the first antenna 210 and the second antenna 220 face satellite 300. When the first antenna 210 and the second antenna 220 receive signals from satellite 300 in an orientation facing satellite 300, satellite communication efficiency can be improved, thus increasing the success rate of receiving response signals and / or ringing alarm signals. Figure 9a While performing operations 907, 909, 911, 913 and / or 915 as shown, the aforementioned second visual object 920 can be displayed on at least one display 290.

[0183] According to an exemplary embodiment, electronic device 101 can improve communication efficiency by controlling the connection state of at least one switching circuit 280 during satellite communication. For example, electronic device 101 can transmit signals to satellite 300 using a first circularly polarized first antenna 210 and a second antenna 220 in a first connection state. After successful signal transmission, electronic device 101 can identify the state with higher reception efficiency between the first and second connection states while receiving signals from satellite 300, and control the at least one switch to the identified state. Due to various variables (such as the location of electronic device 101, the state of electronic device 101, the surrounding environment, weather, and the location of satellite 300), the reception efficiency of the first connection state may be higher than that of the second connection state, or vice versa. According to an exemplary embodiment, electronic device 101 can improve satellite communication efficiency by using the first antenna 210 and the second antenna 220 to receive signals in a state with high reception efficiency.

[0184] The structure of the aforementioned electronic device 101 can be varied. For example, as... Figure 2As shown, the electronic device 101 can be a candybar type. However, it is not limited to this. For example, the electronic device 101 can be a foldable type, which includes a first housing portion that is rotatably coupled (e.g., Figure 10a The first housing portion 1010) and the second housing portion (e.g., Figure 10a The structure of the second housing portion 1020. For example, even when the electronic device 101 is foldable, the electronic device 101 can achieve circular polarization using a first antenna 210 and a second antenna 220 that are orthogonal to each other. For example, the electronic device 101 can achieve circular polarization using a first antenna 210 and a second antenna 220 with linear polarization characteristics through at least one switching circuit 280 capable of providing a first connection state or a second connection state.

[0185] The following text will describe a foldable type of electronic device 101. In addition to the foldable structure, the above references... Figure 2 , Figure 3 , Figures 4a to 4c , Figure 5a , Figure 5b , Figure 6 , Figure 7a , Figure 7b , Figure 8 and Figures 9a to 9c The descriptions provided can be applied substantially equivalently to the electronic device 101 described later. The same reference numerals are used to denote components corresponding to those described above, and repeated descriptions are sometimes omitted.

[0186] Figure 10a An example of an electronic device in an unfolded state according to an exemplary embodiment is shown. Figure 10b An example of a folded state of an electronic device according to an exemplary embodiment is shown. Figure 10c This is an exploded view of an electronic device according to an exemplary embodiment.

[0187] refer to Figure 10a , 10b And 10c, electronic devices (e.g., Figure 1 The electronic device 101 may include a housing 1001, a flexible display 1030 (e.g., Figure 1 The display module 160 and at least one camera 1040.

[0188] For example, housing 1001 may define the exterior of electronic device 101. For example, housing 1001 is the physical exterior of electronic device 101 that is exposed to the outside, and may surround components disposed inside electronic device 101 that are not exposed to the outside. For example, housing 1001 may include a first housing portion 1010, a second housing portion 1020, and a hinge structure 1050.

[0189] For example, the first housing portion 1010 may include a first surface 1011, a second surface 1012 opposite to the first surface 1011, and a first side surface 1013 surrounding at least a portion of the first surface 1011 and the second surface 1012. For example, the first surface 1011 may be referred to as the front surface of the first housing portion 1010, and the second surface 1012 may be referred to as the rear surface of the first housing portion 1010. The first side surface 1013 may be connected to the periphery of the first surface 1011 and the periphery of the second surface 1012. The first surface 1011, the second surface 1012, and the first side surface 1013 may form an interior space of the first housing portion 1010. For example, at least one component may be disposed in the space surrounded by the first surface 1011, the second surface 1012, and the first side surface 1013.

[0190] For example, the second housing portion 1020 may include a third surface 1021, a fourth surface 1022 opposite to the third surface 1021, and a second side surface 1023 surrounding at least a portion of the third surface 1021 and the fourth surface 1022. For example, the third surface 1021 may be referred to as the front surface of the second housing portion 1020, and the fourth surface 1022 may be referred to as the rear surface of the second housing portion 1020. The second side surface 1023 may be connected to the periphery of the third surface 1021 and the periphery of the fourth surface 1022. The third surface 1021, the fourth surface 1022, and the second side surface 1023 may form an internal space of the second housing portion 1020. For example, at least one component may be disposed in the space surrounded by the third surface 1021, the fourth surface 1022, and the second side surface 1023.

[0191] For example, the flexible display 1030 can be configured to display visual information. For example, the flexible display 1030 may include a display area comprising a plurality of pixels. For example, an active area may be referred to as an active area for displaying visual information. For example, the flexible display 1030 may define at least a portion of the front surface of the housing 1001. For example, the flexible display 1030 may define at least a portion of a first surface 1011 and a third surface 1021.

[0192] For example, the flexible display 1030 may include a first display area 1031 defining at least a portion of a first surface 1011 of a first housing, a second display area 1032 defining at least a portion of a third surface 1021 of a second housing, and a third display area 1033 disposed between the first display area 1031 and the second display area 1032. For example, the first display area 1031, the second display area 1032, and the third display area 1033 may define at least a portion of the front surface of the housing 1001. For example, the electronic device 101 may also include a sub-display 1035, which is different from the flexible display 1030. The sub-display 1035 may be disposed on a fourth surface 1022 of the second housing portion 1020. The sub-display 1035 may be referred to as a cover display.

[0193] For example, at least one camera 1040 may be configured to acquire an image based on receiving light from an external object of the electronic device 101. For example, at least one camera 1040 may include a first camera 1041, a second camera 1042, or a third camera 1043. For example, the first camera 1041 may be disposed in a first housing portion 1010. For example, when the electronic device 101 is viewed from above, the first housing portion 1010 may include at least one opening 1041a overlapping the first camera 1041. The first camera 1041 may acquire an image based on receiving light from the outside of the electronic device 101 through at least one opening 1041a.

[0194] For example, a second camera 1042 may be disposed in a second housing portion 1020. When viewed from above, the second housing portion 1020 may include at least one opening 1042a overlapping with the second camera 1042. The second camera 1042 may acquire images based on receiving light from the outside of the electronic device 101 through at least one opening 1042a.

[0195] For example, a third camera 1043 may be disposed in the first housing portion 1010. For example, when the flexible display 1030 is viewed from above, the first display area 1031 of the flexible display 1030 may include at least one opening overlapping with the third camera 1043. The third camera 1043 may acquire an image based on receiving light from the outside of the flexible display 1030 through at least one opening.

[0196] For example, the second camera 1042 and the third camera 1043 may be positioned below the flexible display 1030 (e.g., in the -z direction). For example, the second camera 1042 and / or the third camera 1043 may include an under-display camera (UDC) and / or a punch-hole camera.

[0197] For example, the first housing portion 1010 and the second housing portion 1020 may be rotatably coupled. For example, the second housing portion 1020 may be coupled to the first housing portion 1010 to be rotatable relative to the first housing portion 1010 via a hinge structure 1050.

[0198] For example, hinge structure 1050 can rotatably connect the first housing portion 1010 and the second housing portion 1020. Hinge structure 1050 can be disposed between the first housing portion 1010 and the second housing portion 1020 of electronic device 101, allowing electronic device 101 to be foldable. Hinge structure 1050 allows electronic device 101 to change from an unfolded state to a folded state. Hinge structure 1050 allows electronic device 101 to change from a folded state to an unfolded state. Hinge structure 1050 can hold electronic device 101 in an intermediate state between the unfolded and folded states.

[0199] For example, the unfolded state can be described as a state in which the first display area 1030a faces the same first direction and the second display area 1030b faces the same second direction. For example, the folded state can be described as a state in which the first direction is opposite to the second direction. When the electronic device 101 is in the folded state, the first housing portion 1010 and the second housing portion 1020 can be stacked or overlapped.

[0200] For example, when the electronic device 101 is in a folded state and an intermediate state, the first direction and the second direction may be different from each other. For example, when the electronic device 101 is in a folded state, the first direction and the second direction may be opposite to each other. For example, when the electronic device 101 is in an intermediate state, the first direction may have a slope (e.g., an angle between 0 degrees and 180 degrees) relative to the second direction.

[0201] For example, electronic device 101 can rotate based on a folding axis f. The folding axis f can be referred to as a virtual line extending along a direction parallel to the longitudinal direction of electronic device 101 (e.g., the y-axis) or along a direction parallel to the width direction of electronic device 101 (e.g., the x-axis).

[0202] For example, electronic device 101 may include at least one conductive portion 1014a and 1024a and at least one non-conductive portion 1014b and 1024b included in a first side 1013 and / or a second side 1023. For example, at least one conductive portion 1014a and 1024a can be separated from another conductive portion within the first side 1013 and / or the second side 1023 by contacting at least one non-conductive portion 1014b and 1024b. At least one conductive portion 1014a and 1024a can operate as an antenna radiator for communication with external electronic devices.

[0203] refer to Figure 10c The hinge structure 1050 may include a hinge cover 1051, a first hinge plate 1052, a second hinge plate 1053, and a hinge module 1054. The hinge cover 1051 may surround the internal components of the hinge structure 1050 and define the outer surface of the hinge structure 1050. For example, when the electronic device 101 is in a folded state, at least a portion of the hinge cover 1051 may be exposed to the outside of the electronic device 101 through the first housing portion 1010 and the second housing portion 1020. According to another embodiment, when the electronic device 101 is in an unfolded state, the hinge cover 1051 may be covered by the first housing portion 1010 and the second housing portion 1020 and may not be exposed to the outside of the electronic device 101.

[0204] For example, the first hinge plate 1052 and the second hinge plate 1053 can be rotatably connected to the first housing portion 1010 and the second housing portion 1020 by being operably coupled to them, respectively. For example, the first hinge plate 1052 can be operably coupled to the first support member 1015 of the first housing portion 1010, and the second hinge plate 1053 can be operably coupled to the second support member 1027 of the second housing portion 1020. When the first hinge plate 1052 and the second hinge plate 1053 are operably coupled to the first support member 1015 and the second support member 1027, respectively, the first housing portion 1010 and the second housing portion 1020 can rotate according to the rotation of the first hinge plate 1052 and the second hinge plate 1053.

[0205] The hinge module 1054 can rotate the first hinge plate 1052 and the second hinge plate 1053. For example, the hinge module 1054 can rotate the first hinge plate 1052 and the second hinge plate 1053 based on the folding axis f by including gears that can mesh and rotate.

[0206] For example, a first housing portion 1010 may include a first support member 1015 and a rear cover 1016. The first support member 1015 may be disposed inside the first housing portion 1010 and may support at least one component disposed in the first housing portion 1010. The rear cover 1016 may define at least a portion of a second surface 1012 of the first housing portion 1010. For example, a second housing portion 1020 may include a second support member 1027. The second support member 1027 may be disposed inside the second housing portion 1020 and may support at least one component disposed in the second housing portion 1020. For example, a sub-display 1035 may be disposed below the second support member 1027 (e.g., in the -z direction).

[0207] According to an exemplary embodiment, in addition to the at least one camera 1040 described above, the electronic device 101 may also include multiple electronic components for implementing various functions. For example, the electronic device 101 may include a first printed circuit board 1061, a second printed circuit board 1062, a connection structure (e.g., a flexible printed circuit board) 1063, and / or a battery 189. The electronic components described above are merely illustrative and are not limited thereto.

[0208] For example, a first printed circuit board 1061 and a second printed circuit board 1062 may respectively provide electrical connections for components in the electronic device 101. For example, the first printed circuit board 1061 may be disposed in a first housing portion 1010, and the second printed circuit board 1062 may be disposed in a second housing portion 1020. The first printed circuit board 1061 may provide electrical connections between electronic components disposed in the first housing portion 1010. The second printed circuit board 1062 may provide electrical connections between electronic components disposed in the second housing portion 1020. A connection structure 1063 may electrically connect the first printed circuit board 1061 and the second printed circuit board 1062. For example, the connection structure 1063 may extend from the first printed circuit board 1061 to the second printed circuit board 1062 across a hinge structure 1050. For example, the connection structure 1063 may at least partially overlap with the hinge structure 1050.

[0209] For example, battery 189 may be a means for powering at least one component of electronic device 101, and may include a non-rechargeable primary battery and / or a rechargeable secondary battery.

[0210] For example, electronic device 101 may include multiple antennas ANT1, ANT2, ANT3, and ANT4 for communicating with external electronic devices. For example, electronic device 101 may include a main antenna ANT1, a sub-antenna ANT2, an ultra-wideband (UWB) antenna ANT3, and / or an antenna ANT4 for near-field wireless communication. However, it is not limited to this.

[0211] Figure 11a and Figure 11b An electronic device according to an exemplary embodiment is illustrated schematically.

[0212] refer to Figure 11a According to an exemplary embodiment, the electronic device 101 may include a first housing portion 1010 and a second housing portion 1020. For example, the second housing portion 1020 may be rotatably fastened to the first housing portion 1010 based on a folding axis f. For example, the electronic device 101 may include a hinge structure 1050 that rotatably connects the first housing portion 1010 and the second housing portion 1020.

[0213] For example, the first housing portion 1010 may include a first frame 1110 defining at least a portion of the sides of the first housing portion 1010. For example, the first frame 1110 may include conductive and non-conductive portions. The conductive portion may operate as an antenna radiator for transmitting and / or receiving signals in a specified frequency band (e.g., about 1.6 GHz). The non-conductive portion may contact both ends of the conductive portion used as an antenna radiator to electrically isolate the conductive portion used as an antenna radiator from other conductive portions.

[0214] For example, the first frame 1110 may include a first edge portion 1111, a second edge portion 1112, and a third edge portion 1113. For example, the first frame 1110 may include a first edge portion 1111 defining at least a portion of the upper part (e.g., in the +y direction) of the first housing portion 1010, a second edge portion 1112 defining at least a portion of one side (e.g., in the +x direction) edge of the electronic device 101, and a third edge portion 1113 opposite to the first edge portion 1111. For example, the first edge portion 1111 and the third edge portion 1113 may be perpendicular to the second edge portion 1112. For example, the length of the second edge portion 1112 may be longer than the length of the first edge portion 1111. For example, the third edge portion 1113 may define at least a portion of the bottom (e.g., in the -y direction) edge of the electronic device 101.

[0215] According to an exemplary embodiment, electronic device 101 may include a first antenna 210 and a second antenna 220 for transmitting and / or receiving signals in a specified frequency band (e.g., approximately 1.6 GHz). For example, the first antenna 210 may be configured substantially perpendicular to the second antenna 220. For example, the first antenna 210 may be formed at least partially along a first edge portion 1111 or a third edge portion 1113. For example, the second antenna 220 may be formed at least partially along a second edge portion 1112 or a fourth edge portion 1121. Since the first edge portion 1111 and the third edge portion 1113 are perpendicular to the second edge portion 1112, the first antenna 210 and the second antenna 220 may be configured substantially perpendicular. However, this is not a limitation. For example, the first antenna 210 may be formed at least partially along the second edge portion 1112, and the second antenna 220 may be formed at least partially along the first edge portion 1111 or the third edge portion 1113. In order to achieve circular polarization according to various embodiments of the present disclosure, the first antenna 210 and the second antenna 220 have only a structure that is perpendicular to each other, and the positions of the first antenna 210 and the second antenna 220 are not limited to specific edge portions.

[0216] For example, the second antenna 220, which is at least partially formed in the second edge portion 1112, can be positioned at a first location 1101 or a second location 1102 including the corner of the frame 230, or at a third location 1103 spaced apart from the corner of the frame 230. To suppress the appearance of grating lobes, the distance between the first antenna 210 and the second antenna 220 can be less than or equal to about half the wavelength corresponding to the operating frequency (e.g., about 1.6 GHz). For example, when the first antenna 210 is at least partially formed along the first edge portion 1111, the second antenna 220 can be positioned at the first location 1101 or the third location 1103. For example, when the first antenna 210 is at least partially formed along the third edge portion 1113, the second antenna 220 can be positioned at the second location 1102 or the third location 1103.

[0217] The positions of the first antenna 210 and the second antenna 220 described above are merely descriptions of the first antenna 210 and the second antenna 220 for radial circular polarization. The electronic device 101 may also include other antennas different from the first antenna 210 and the second antenna 220. For example, when the first antenna 210 is formed at least partially along the first edge portion 1111 and the second antenna 220 is formed at least partially along a portion of the second edge portion 1112, the electronic device 101 may include one or more other antennas formed at least partially along another portion of the second edge portion 1112 and / or the third edge portion 1113. For example, one or more other antennas may be formed at least partially along the second frame 1120, thereby forming at least a portion of the side surface of the second housing portion 1020. For example, one or more other antennas formed at least partially along the second frame 1120 may be symmetrical to the antenna formed at least partially along the first frame 1110 based on the folding axis f. However, this is not a limitation.

[0218] For example, electronic device 101 may include at least one of the processors described above (e.g., Figure 3 At least one processor 240), RF transceiver (e.g., Figure 3 RF transceiver 250), phase shifter (e.g., Figure 3 Phase shifter 260) and at least one switching circuit (e.g., Figure 3 At least one switching circuit 280). The above description can be applied to components in substantially the same manner. For example, at least one switching circuit 280 can be configured to selectively provide a first connection state or a second connection state. For example, the first connection state may be referred to as... Figure 4a The state shown, and the second connection state can be called Figure 4c The state shown in the image.

[0219] For example, in the first connection state, the first antenna 210 and the second antenna 220 can be configured for radial circular polarization. Circular polarization can be achieved based on the difference between the phase of the signal input to the first antenna 210 and the phase of the signal input to the second antenna 220 via the phase shifter 260. For example, when the first antenna 210 and the second antenna 220 communicate with external electronic equipment (e.g., satellite 300), radial circular polarization can improve the satellite communication efficiency of electronic equipment 101.

[0220] For example, at least one processor 240 may be configured to control at least one switching circuit 280 based on a first reception quality of a first signal received via the first antenna 210 and the second antenna 220 in a first connection state and a second reception quality of a second signal received via the first antenna 210 and the second antenna 220 in a second connection state. For example, at least one processor 240 may be configured to control at least one switching circuit 280 to a first connection state based on the identification that the first reception quality is higher than the second reception quality. For example, at least one processor 240 may be configured to control at least one switching circuit 280 to a second connection state based on the identification that the second reception quality is higher than the first reception quality. For example, electronic device 101 can improve satellite communication efficiency by confirming a state with high satellite communication efficiency and performing satellite communication based on the confirmed state.

[0221] For example, electronic device 101 may have a structure in which the edge portions parallel to the folding axis f (e.g., the second edge portion 1112 and the fifth edge portion 1122) are longer than the edge portions perpendicular to the folding axis f (e.g., the first edge portion 1111, the third edge portion 1113, the fourth edge portion 1121, and the sixth edge portion 1123). However, it is not limited to this. Figure 11b As explained in the text, the edge portion parallel to the folding axis f can also have a shorter structure than the edge portion perpendicular to the folding axis f.

[0222] refer to Figure 11b The electronic device 101 may include a housing having a structure in which the edge portion perpendicular to the folding axis f is longer than the edge portion parallel to the folding axis f. For example, the housing may include a first housing portion 1010 and a second housing portion 1020 rotatably coupled to the first housing portion 1010.

[0223] For example, the first housing portion 1010 may include a first frame 1110 and a second frame 1120, the first frame 1110 defining at least a portion of the side surface of the first housing portion 1010, and the second frame 1120 defining at least a portion of the side surface of the second housing portion 1020. For example, the first frame 1110 and the second frame 1120 may include conductive and non-conductive portions. The conductive portion can be used as an antenna radiator for transmitting and / or receiving signals in a specified frequency band (e.g., about 1.6 GHz).

[0224] For example, the first frame 1110 may include a first edge portion 1111, a second edge portion 1112, and a third edge portion 1113. For example, the frame 1110 may include a first edge portion 1111 defining at least a portion of the upper (e.g., +y direction) edge of the first housing portion 1010, a second edge portion 1112 defining at least a portion of one side (e.g., +x direction) edge of the electronic device 101, and a third edge portion 1113 defining at least a portion of the other side (e.g., -x direction) edge of the electronic device 101. For example, the first edge portion 1111 may be perpendicular to the second edge portion 1112 and the third edge portion 1113. For example, the lengths of the second edge portion 1112 and the third edge portion 1113 may be longer than the length of the first edge portion 1111.

[0225] For example, the second frame 1120 may include a fourth edge portion 1121, a fifth edge portion 1122, and a sixth edge portion 1123. For example, the second frame 1120 may include a fourth edge portion 1121 defining at least a portion of the bottom (e.g., -y direction) edge of the second housing portion 1020, a fifth edge portion 1122 defining at least a portion of one side (e.g., +x direction) edge of the electronic device 101, and a sixth edge portion 1123 defining at least a portion of the other side (e.g., -x direction) edge of the electronic device 101. For example, the fourth edge portion 1121 may be perpendicular to the fifth edge portion 1122 and the sixth edge portion 1123. For example, the lengths of the fifth edge portion 1122 and the sixth edge portion 1123 may be longer than the length of the fourth edge portion 1121.

[0226] For example, electronic device 101 may include a first antenna 210 and a second antenna 220. For example, the first antenna 210 may be positioned perpendicular to the second antenna 220. For example, the distance between the first antenna 210 and the second antenna 220 may be less than or equal to about half the wavelength corresponding to the operating frequency (e.g., about 1.6 GHz) in order to suppress the appearance of grating lobes.

[0227] For example, the first antenna 210 may be formed at least partially along the first edge portion 1111. For example, the second antenna 220 may be formed at least partially along the second edge portion 1112 or the third edge portion 1113. However, it is not limited to this. For example, the first antenna 210 may be formed at least partially along the fourth edge portion 1121. For example, the second antenna 220 may be formed at least partially along the fifth edge portion 1122 or the sixth edge portion 1123. Figure 11a and Figure 11b The first antenna 210 and the second antenna 220 of the electronic device 101 shown can be configured to be radially circularly polarized (e.g., RHCP).

[0231] For example, the first antenna 210 and the second antenna 220 can be configured to radiate circular polarization based on the phase difference between the phase of the signal before passing through the phase shifter 260 and the phase of the signal after passing through the phase shifter 260 in the first connection state.
