Abstract

Embodiments of the present application provide an electronic device. The electronic device may comprise a first antenna and a second antenna, wherein the first antenna may be provided at a top edge of the electronic device, and the second antenna may be provided at a top corner. A radiator of the second antenna may be connected to a second tuning switch, and the second tuning switch may have the following switch states: a first switch state and a second switch state, wherein when the second tuning switch is in the first switch state, a current near a first frequency is distributed on the radiator of the second antenna, and when the second tuning switch is in the second switch state, no current near the first frequency is distributed on the radiator of the second antenna.

Description

Antenna devices and electronic equipment

[0001] This application claims priority to Chinese Patent Application No. 202510127964.0, filed on January 27, 2025, entitled “Antenna Device and Electronic Equipment”, the entire contents of which are incorporated herein by reference. Technical Field

[0002] This application relates to the field of antenna technology, and more particularly to antenna devices and electronic equipment. Background Technology

[0003] In satellite communications, signals experience significant transmission loss during propagation in space, necessitating antennas with strong directivity and high signal gain to ensure communication quality. The design of high-gain satellite communication antennas in portable electronic devices such as mobile phones is a significant concern in this field. Mobile phones and similar portable electronic devices contain various components such as screens, batteries, and camera modules, leaving very limited space for antenna design. This presents a challenge to the design of satellite communication antennas in mobile phones. Summary of the Invention

[0004] In a first aspect, embodiments of this application provide an electronic device, which may include: a first antenna, a second antenna, a first tuning switch, a second tuning switch, and a peripheral conductive structure. The peripheral conductive structure may include multiple frames, which may include a first frame and a second frame. The first frame and the second frame are connected to form a first corner, and the second frame extends in a different direction than the first frame. Wherein:

[0005] The first antenna can be located at the first edge of the electronic device, and the second antenna can be located at the first corner.

[0006] The radio frequency signal source of the first antenna is the first signal source, and the operating frequency of the first antenna is the first frequency; the radio frequency signal source of the second antenna is the second signal source, and the operating frequency of the second antenna is the second frequency.

[0007] The first tuning switch can be connected to the radiator of the first antenna, and the second tuning switch can be connected to the radiator of the second antenna. When the first antenna is working, the second tuning switch has the following switching states: first switching state and second switching state. When the second tuning switch is in the first switching state, a current near the first frequency is distributed on the radiator of the second antenna. When the second tuning switch is in the second state, no current near the first frequency is distributed on the radiator of the second antenna.

[0008] Thus, when the second tuning switch is switched to the first switching state, in addition to the current at its transmission frequency distributed on the radiator of the first antenna, the radiator of the second antenna also has a current near its transmission frequency distributed on its own. At this time, the second antenna is used as a parasitic antenna for the first antenna, resulting in a wider radiation pattern coverage and a broad beam, facilitating satellite targeting. However, when the second tuning switch is switched to the second switching state, the radiator of the first antenna still has a current at its transmission frequency, but the radiator of the second antenna does not have a current near the first antenna's transmission frequency. At this time, the second antenna is not used as a parasitic antenna for the first antenna; the current of the first antenna is only distributed on its own radiator. The radiation pattern of the first antenna has a narrower coverage and a narrower beam, but the antenna gain is improved, resulting in better signal quality.

[0009] In the first aspect, the first antenna can be a satellite communication antenna, and the second antenna can be a Class I (FR1) operating frequency band antenna in the sub-6G frequency band.

[0010] In conjunction with the first aspect, in some embodiments, the first corner is the corner closest to the first antenna among multiple corners, which is beneficial for the first antenna to couple to the second antenna. Here, distance can refer to center distance, i.e., the distance between the center points of two objects, or the distance between the nearest adjacent endpoints, or the distance measured by other methods.

[0011] In conjunction with the first aspect, in some embodiments, the electronic device may further include a third antenna and a third tuning switch, with the third antenna disposed at the second frame. The radio frequency signal source of the third antenna is a third signal source, and the operating frequency of the three antennas is a third frequency. The third tuning switch may be connected to the radiator of the third antenna. When the first antenna is operating, the second tuning switch may be in a first switching state, and the third tuning switch may be in a third switching state, with current near the first frequency distributed on the radiator of the third antenna. When the first antenna is operating, the second tuning switch may be in a second switching state, and the third tuning switch may be in a fourth switching state, with no current near the first frequency distributed on the radiator of the third antenna. Thus, the current distribution on the antenna stub can be changed by controlling the switching states of the second and third tuning switches together. The third antenna can be used together with the second antenna as a parasitic antenna of the first antenna to expand the signal beam of the first antenna, or the third antenna can be used without either the second antenna as a parasitic antenna to narrow the signal beam of the first antenna, thereby improving antenna gain.

[0012] The third antenna can be a mid-to-high frequency antenna for cellular mobile communication.

[0013] In conjunction with the first aspect, in some embodiments, the first and second antennas can be implemented as frame antennas, that is, utilizing the conductive frame of the electronic device as the radiator of the first and second antennas. Specifically, a first slit can be provided on the first frame near the first corner, and a second slit can be provided on the second frame. The radiator of the first antenna may include a first portion of the first frame, which may be located on a first side of the first slit, the first side being the side of the first frame facing away from the first corner. The radiator of the second antenna includes the frame between the first and second slits.

[0014] In conjunction with the first aspect, in some embodiments, the third antenna can also be implemented as a frame antenna. The radiator of the third antenna may include a first portion of the second frame, which is located on the second side of the second slit, and the second side is the side of the second frame that faces away from the first corner.

[0015] In conjunction with the first aspect, in some embodiments, the feed point of the first antenna is located on the radiator of the first antenna. To enhance the coupling effect on the second antenna, the distance between the feed point of the first antenna and the first slit is less than a preset distance value.

[0016] In conjunction with the first aspect, in some embodiments, a matching circuit is provided at the second slit to connect the second antenna and the third antenna. The matching circuit is used to block the signal current of the second frequency while allowing the signal current of the first frequency to pass through.

[0017] In conjunction with the first aspect, in some embodiments, the first frequency may include the transmit frequency and receive frequency of the first antenna. A first tuning switch may be used to tune the resonant frequency of the first antenna to either the transmit or receive frequency. The first tuning switch may be connected to a controller, such as a modem. When the first antenna is used for signal reception, the controller may control the first tuning switch to adjust the resonant frequency of the first antenna to the receive frequency; when the first antenna is used for signal transmission, the controller may control the first tuning switch to adjust the resonant frequency of the first antenna to the transmit frequency.

[0018] In conjunction with the first aspect, in some embodiments, to avoid the influence of hand grip, the first antenna, the second antenna, and the third antenna can all be positioned in the upper half of the electronic device. Furthermore, since the motherboard is generally stacked on the upper part of the device, placing them in the upper half can also shorten the coaxial cable supplying power to the antennas, reducing path loss. Here, "upper half" refers to the part of the device closer to the top bezel, as opposed to the lower half closer to the bottom bezel; generally, it refers to the part of the device above the line connecting the midpoints of the two side bezels.

[0019] Secondly, embodiments of this application provide a radiation pattern control method, which can be applied to an electronic device, the electronic device being the one described in the first aspect. The method may include: initiating satellite communication and controlling a second tuning switch to a first switching state; detecting a change in the attitude of the electronic device during satellite communication, and controlling the second tuning switch to a second switching state when a first beam points to the satellite, wherein the first beam is the beam of the satellite communication signal when the second tuning switch is in the second switching state.

[0020] The second method involves initially setting the second tuning switch to the first switch state at the start of satellite communication. This allows the second antenna to be used as a parasitic antenna for the first antenna, improving the radiation pattern coverage of the first antenna and achieving a wide-beam satellite communication antenna for easier satellite alignment. When the user adjusts the attitude of their electronic device to align with the satellite, if the first beam is found to be pointing towards the satellite, the second tuning switch is then set to the second switch state. In this way, the second antenna is no longer used as a parasitic antenna for the first antenna, the first antenna's beam narrows, and the antenna gain increases, which is beneficial for improving satellite call quality.

[0021] In the second aspect, the first beam is the beam of the first antenna when the second antenna is not used as a parasitic antenna for the first antenna; it is a narrow beam. The direction of the first beam can be determined by the relative position of the electronic device and the satellite, as well as the beam angle of the first beam. Specifically, the electronic device can determine whether the first beam is pointing at the satellite based on its relative position and the beam angle. The relative position of the electronic device and the satellite can be determined based on satellite ephemeris data, while the beam angle of the first beam can be determined based on the electronic device's position on Earth, its attitude, and the beam pattern. The electronic device's position on Earth can be detected using devices such as a compass or Global Positioning System (GPS).

[0022] In conjunction with the second aspect, in some embodiments, the method may further include: when the second tuning switch is in the first switching state, controlling the third tuning switch to be in the third switching state, so that the third antenna is also used as a parasitic antenna of the first antenna at the beginning of satellite communication, so as to further improve the radiation pattern coverage of the first antenna and form a wider beam; when a change in the attitude of the electronic device is detected during satellite communication, and when the first beam is pointing at the satellite, controlling the third tuning switch to be in the fourth switching state.

[0023] In conjunction with the second aspect, in some embodiments, the method may further include: during the uplink phase of satellite communication, controlling the first tuning switch to tune the resonant frequency of the first antenna to the transmission frequency; during the downlink phase of satellite communication, controlling the first tuning switch to tune the resonant frequency of the first antenna to the reception frequency, the second and third antennas no longer serve as parasitic antennas of the first antenna, the beam of the first antenna becomes narrower, the antenna gain becomes stronger, which is beneficial to improving the quality of satellite calls.

[0024] In conjunction with the second aspect, in some embodiments, before controlling the second tuning switch to be in the second switching state, the method further includes: determining whether the first beam is pointing at the satellite based on the relative position of the electronic device and the satellite, and the beam angle of the first beam; wherein the relative position of the electronic device and the satellite is determined based on satellite ephemeris data, and the beam angle of the first beam is determined based on the position of the electronic device on Earth, the attitude of the electronic device, and the radiation pattern of the first beam.

[0025] In conjunction with the second aspect, in some embodiments, the electronic device can further determine that the second beam is pointing to the satellite before determining whether the first beam is pointing to the satellite. The second beam is the satellite communication beam when the second tuning switch is in the first switch combination state. In this way, after determining that the wide beam (second beam) is pointing to the satellite, the decision to switch to the narrow beam (first beam) can be made, thus saving processing steps.

[0026] Thirdly, embodiments of this application also provide a computer-readable storage medium storing a computer program that, when executed by a processor, can implement the steps of the pattern control method described in the second aspect.

[0027] Fourthly, embodiments of this application also provide a computer program that, when executed by a processor, can implement the steps of the direction pattern control method described in the second aspect. Attached Figure Description

[0054] The terminology used in the following embodiments of this application is for the purpose of describing particular embodiments only and is not intended to be a limitation of this application.

[0055] Figure 1 illustrates a design scheme for a satellite communication antenna. As shown in Figure 1, in this design, the satellite communication antenna radiator is positioned at the top of the mobile phone, with both ends open. A feed point is located near one end (position A), and a ground point is located at position B in the middle of the radiator. A tuning switch SW is located at position A' between positions A and B. This tuning switch SW is connected to a communication module such as a modem, allowing it to be controlled by the modem to change its switching state, thereby adjusting the antenna's resonant frequency. When BeiDou satellite navigation is not activated, the tuning switch defaults to the optimal state for the Global Positioning System (GPS), causing the satellite antenna to resonate in the GPS satellite navigation frequency band. When BeiDou satellite navigation is activated, the modem can control the tuning switch SW at position A' to switch to the BeiDou optimal state, causing the antenna to resonate in the BeiDou satellite navigation frequency band. When BeiDou satellite navigation is completed, the modem can control the tuning switch SW to switch back to the GPS optimal state. This design improves the performance of both BeiDou and GPS satellite navigation.

[0056] However, the satellite communication antenna shown in Figure 1 is a satellite navigation and positioning antenna, unsuitable for satellite calling scenarios. Its radiation pattern is narrow, which is detrimental to satellite alignment. The primary tasks of satellite navigation are navigation and positioning. Although it can also be used to send and receive short messages, current satellite navigation technology does not support free editing of SMS content; users can only send preset messages. Satellite calling, on the other hand, is a more powerful communication function. It allows users to make voice calls in areas without terrestrial signal coverage and to send and receive freely edited SMS messages. Satellite communication antennas require high-gain, wide-beam antennas.

[0057] This application provides an antenna design scheme that can be applied to satellite communication scenarios in electronic devices such as mobile phones. By making full use of the overall antenna distribution, a high-gain, wide-beam satellite communication antenna can be designed within the limited clearance of the electronic device.

[0058] Figure 2 illustrates an electronic device 10 provided in an embodiment of this application. As shown in Figure 2, the electronic device 10 may include a screen 11 and a back cover disposed opposite to the screen 11. In Figure 2, the back cover is not visible because it is behind the screen 11.

[0059] The electronic device 10 may also include multiple bezels, such as bezels 13A, 13B, 13C, and 13D. These multiple bezels are connected end to end to form the middle frame of the electronic device 10. The middle frame, together with the screen 11 and the back cover, encloses the internal components of the electronic device 10, such as the camera, audio circuit, processor, battery, etc. Among these multiple bezels, adjacent bezels with different extension directions are connected to each other to form multiple corners of the electronic device 10, such as corners 15A, 15B, 15C, and 15D. In Figure 2, corner 15A is formed by connecting the horizontally extending border 13A and the vertically extending border 13B; corner 15B is formed by connecting the horizontally extending border 13A and the vertically extending border 13D; corner 15C is formed by connecting the vertically extending border 13D and the horizontally extending border 13C; and corner 15D is formed by connecting the vertically extending border 13B and the horizontally extending border 13C.

[0060] A corner is a range of locations, as shown in Figure 3. It can include the connecting contact segments of the two borders forming the corner, such as 21A and 21B, and the semi-enclosed area 22 of these two segments (shown in shaded areas in Figure 3). The size of the corner depends on the lengths of 21A and 21B, and can be determined according to actual application requirements. This application embodiment does not impose any limitations on this.

[0061] Depending on their position within the electronic device, bezel 13A can be called the top bezel, bezel 13C the bottom bezel, and bezels 13B and 13D the side bezels. Corners 15A and 15B can be called top corners, and corners 15C and 15D the bottom corners. The transition between the side bezel and the top bezel can be called the top corner bezel, and the transition between the side bezel and the bottom bezel can be called the bottom corner bezel. The terms "top" and "bottom" refer to portrait mode usage. In portrait mode usage of electronic device 10, the top is the end of the device facing upwards (upwards), and the bottom is the end of the device facing downwards (downwards). The top of electronic device 10 may house devices such as a noise-canceling microphone (not shown), a camera (not shown), an earpiece (not shown), and a proximity sensor (not shown); the bottom of electronic device 10 typically houses a main microphone (not shown) and a USB charging port (not shown). The sides of the electronic device may have volume control buttons (not shown) and a power button (not shown).

[0062] As shown in Figure 2, the electronic device 10 may further include a first antenna 17 and a second antenna 18. The antennas are simplified in Figure 2 using dashed boxes. The first antenna 17 may be located at the top edge 13A of the electronic device 10, and the second antenna 18 may be located at the top corner 15A. The top corner 15A may be the corner closest to the first antenna 17 among multiple corners of the electronic device 10, which facilitates the coupling of the first antenna 17 to the second antenna. Here, distance can refer to center-to-center distance, i.e., the distance between the center points of two objects, or the distance between the nearest adjacent endpoints, or a distance measured using other methods.

[0063] The first antenna 17 uses a radio frequency (RF) signal source as its primary signal source, and its operating frequency is a primary frequency. The second antenna 18 uses an RF signal source as its secondary signal source, and its operating frequency is a secondary frequency. The first antenna 17 can be a satellite communication antenna, and the second antenna 18 can be a Class 1 (FR1) antenna operating in the sub-6GHz frequency band, such as a combined N79 (4.4GHz-5.0GHz) and N78 (3.3GHz-3.8GHz) antenna. When the second antenna is in operation, its operating frequency can be adjusted to N79 or N78 using a tuning switch. The operating frequency of an antenna refers to the frequency range within which it receives and transmits electromagnetic waves, usually expressed in Hertz (Hz). It can be a single frequency or a continuous frequency range. Different types of antennas correspond to different operating frequencies; the first antenna 17 and the second antenna 18 are of different types.

[0064] The first antenna 17 and the second antenna 18 can be implemented as a frame antenna, as shown in Figure 4B. That is, the conductive frame of the electronic device 10 is used as the radiator of the first antenna 17 and the second antenna 18.

[0065] Figure 4A briefly illustrates the principle structure of implementing the first antenna 17 and the second antenna 18 based on the frame.

[0066] As shown in Figure 4A, the top frame 13A and the side frame 13B are connected at the top corner. A slot 25 may be provided on the top frame 13A, and a slot 26 may be provided on the side frame 13B. The slot 25 can be the slot on the top frame 13A closest to the first frame connection point, and the slot 26 can be the slot on the side frame 13B closest to the first frame connection point. The first frame connection point refers to the connection point between the side frame 13B and the top frame 13A. This is a positional concept and does not require a connection between the side frame 13B and the top frame 13A at this point in the manufacturing process. The entire peripheral conductive frame can be integrally formed, and no connection point may be required in the manufacturing process. The radiator of the first antenna 17 may include a first part 20A of the top frame 13A, which is the top frame portion on the first side of the slot 25. Here, the first side is the side of the top frame 13A that faces away from the top corner 15A. The radiator of the second antenna 18 may include a frame 21A between the slots 25 and 26, which is a top corner frame.

[0067] The feed point 20B of the first antenna 17 can be disposed on the first part 20A, and the feed point 20B is connected to the first signal source. The feed point 21B of the second antenna 18 can be disposed on the frame 21A, and the feed point 21B is connected to the second signal source. To enhance the coupling effect to the second antenna 18, the feed point 20B of the first antenna 17 can be disposed close to the slot 25, and the distance between the two is less than a preset distance value, for example, the distance from the feed point 20B to the slot 25 is within 10 mm. The example is only used to explain the embodiments of this application, and may differ in actual applications, and should not be construed as limiting.

[0068] As shown in Figure 4A, in the electronic device 10, the radiator 20A of the first antenna 17 can be connected to the first tuning switch 20C, and the radiator 21A of the second antenna 18 can be connected to the second tuning switch 21C. The first tuning switch 20C is used to adjust the resonant frequency of the first antenna 17, and the second tuning switch 21C is used to adjust the resonant frequency of the second antenna 18.

[0069] The first tuning switch 20C can be positioned close to the feed point 20B, meaning the distance between them is less than a preset distance (e.g., 3 mm). They can even be mounted on the same connecting pad, which can be an extension of a metal frame that extends inward to contact the metal spring on the PCB, thus forming an electrical connection with the feed source and tuning switch circuit on the PCB. To distinguish between the first tuning switch 20C and the feed point 20B, Figure 4A shows the first tuning switch 20C and the feed point 20B mounted on two separate connecting pads. However, in practical applications, they can share a single connecting pad, connecting to the feed source and tuning switch circuit on the PCB respectively.

[0070] The second tuning switch 21C can be located close to the feed point 21B, or even both can be located on the same pad.

[0071] The second tuning switch 21C can have the following switching states: a first switching state and a second switching state. When the second tuning switch 21C is in the first switching state, a current near the first frequency is distributed on the radiator of the second antenna 18. When the second tuning switch 21C is in the second switching state, no current near the first frequency is distributed on the radiator of the second antenna 18. Thus, by changing the switching state of the second tuning switch 21C, the second antenna 18 can become a parasitic antenna of the first antenna 17, thereby changing the current distribution of the first antenna 17 and adjusting its radiation pattern. When the first antenna 17 operates at the first frequency, the second antenna 18 can be inactive. Here, inactive second antenna 18 means that the signal transceiver circuit of the second antenna 18 is inactive, such as by disconnecting the path between the second antenna 18 and its signal transceiver circuit.

[0072] The first frequency may include the transmission frequency and the reception frequency of the first antenna 17. A first tuning switch 20C can be used to switch the resonant frequency of the first antenna 17 between its transmission and reception frequencies. The first tuning switch 20C can be connected to a controller, such as a modem. When the first antenna 17 is used for signal reception, the controller can control the first tuning switch 20C to adjust the resonant frequency of the first antenna 17 to the reception frequency; when the first antenna 17 is used for signal transmission, the controller can control the first tuning switch 20C to adjust the resonant frequency of the first antenna 17 to the transmission frequency.

[0073] The first antenna 17 can be a satellite communication antenna, with a transmission frequency of, for example, 1980MHz-2010MHz and a reception frequency of, for example, 2170MHz-2200MHz.

[0074] The following example uses the first antenna 17 as a satellite communication antenna. Figures 5-11 and 12-18 are used to illustrate how different switching states of the second tuning switch 21C affect the signal transmission and reception of the first antenna 17.

[0075] Figures 5 and 6 compare the simulation results caused by the second tuning switch 21C being in different switching states when the first antenna 17 transmits a signal. Specifically, Figure 5 shows the simulation results of the first antenna 17 when the second tuning switch 21C is switched to the first switching state, and Figure 6 shows the simulation results of the first antenna 17 when the second tuning switch 21C is switched to the second switching state. It can be seen that by switching the second tuning switch 21C to the first switching state, there is a resonance point A approximately 100 MHz before the satellite communication transmission resonance point (1.9984 GHz). This resonance point is about 100 MHz smaller than the satellite communication transmission resonance point. This resonance point is generated by the coupling of the second antenna 18 to the first antenna 17, and its frequency is near the transmission frequency of the first antenna 17.

[0076] Figures 7 and 8 compare the current distribution changes caused by the second tuning switch 21C being in different switching states when the first antenna 17 transmits a signal, with arrows indicating the current direction. Specifically, Figure 7 shows the current distribution on the antenna stub when the second tuning switch 21C is switched to the first switching state, and Figure 8 shows the current distribution on the antenna stub when the second tuning switch 21C is switched to the second switching state.

[0077] As shown in Figures 7 and 8, when the second tuning switch 21C is switched to the first switch state, in addition to the current at its transmission frequency distributed on the radiator of the first antenna 17, the radiator of the second antenna 18 also has a current near its transmission frequency distributed on it. At this time, the second antenna 18 is used as a parasitic antenna for the first antenna 17, resulting in a wider coverage area for the radiation signal of the first antenna 17, forming a wide beam, which is convenient for users to target satellites. However, when the second tuning switch 21C is switched to the second switch state, the radiator of the first antenna 17 still has a current at its transmission frequency, but the radiator of the second antenna 18 does not have a current near the transmission frequency of the first antenna 17. At this time, the second antenna 18 is not used as a parasitic antenna for the first antenna 17, and the current of the first antenna 17 is only distributed on its own radiator. The radiation signal of the first antenna 17 has a narrower coverage area and a narrower beam, but the antenna gain is improved, resulting in better signal quality.

[0078] Figure 9 shows the transmission pattern data of the first antenna 17 when the second tuning switch 21C is in the first switch state, and Figure 10 shows the transmission pattern data of the first antenna 17 when the second tuning switch 21C is in the second switch state. Additionally, Figure 11 shows the pattern gain of the pattern data shown in Figure 10 compared to the pattern data shown in Figure 9. It can be seen that within the observation angle range of theta 40 to 60 degrees and phi 110 to 220 degrees, the values ​​representing signal gain in Figure 8 show an improvement. The values ​​in Figures 9-11 are in dB.

[0079] Figures 12 and 13 compare the simulation results caused by the second tuning switch 21C being in different switching states when the first antenna 17 receives a signal. Specifically, Figure 12 shows the simulation results of the first antenna 17 when the second tuning switch 21C is switched to the first switching state, and Figure 13 shows the simulation results of the first antenna 17 when the second tuning switch 21C is switched to the second switching state. It can be seen that by switching the second tuning switch 21C to the first switching state, a resonance point B is found approximately 200 MHz behind the satellite communication signal receiving resonance point (2.2065 GHz). This resonance point is approximately 200 MHz higher than the satellite communication signal receiving resonance point, and it is generated by the coupling of the second antenna 18 to the first antenna 17, with its frequency near the receiving frequency of the first antenna 17.

[0080] Figures 14 and 15 compare the current distribution changes caused by the second tuning switch 21C being in different switching states when the first antenna 17 receives a signal, with arrows indicating the current direction. Specifically, Figure 14 shows the current distribution on the antenna stub when the second tuning switch 21C is switched to the first switching state, and Figure 15 shows the current distribution on the antenna stub when the second tuning switch 21C is switched to the second switching state.

[0081] As shown in Figures 14-15, when the second tuning switch 21C is switched to the first switch state, in addition to the current at its receiving frequency distributed on the radiator of the first antenna 17, the radiator of the second antenna 18 also has a current near the receiving frequency of the first antenna 17 distributed on it. At this time, the second antenna 18 is used as a parasitic antenna for the first antenna 17, resulting in a wider coverage area and a wider beam for the radiation signal of the first antenna 17, facilitating satellite targeting. However, when the second tuning switch 21C is switched to the second switch state, the radiator of the first antenna 17 still has a current at its receiving frequency, but the radiator of the second antenna 18 does not have a current near the receiving frequency of the first antenna 17 distributed on it. At this time, the second antenna 18 is not used as a parasitic antenna for the first antenna 17, and the current of the first antenna 17 is only distributed on its own radiator. The radiation signal of the first antenna 17 has a narrower coverage area and a narrower beam, but the antenna gain is improved, resulting in better signal quality.

[0082] Figure 16 shows the received radiation pattern data of the first antenna 17 when the second tuning switch 21C is in the first switch state, and Figure 17 shows the received radiation pattern data of the first antenna 17 when the second tuning switch 21C is in the second switch state. Additionally, Figure 18 shows the radiation pattern gain presented by the radiation pattern data shown in Figure 16 compared to the radiation pattern data shown in Figure 17. It can be seen that within the observation angle range of theta 25 to 60 degrees and phi 60 to 220 degrees, the values ​​representing signal gain in Figure 16 show an improvement. The values ​​in Figures 16-18 are in dB.

[0083] Furthermore, as shown in Figure 2, the electronic device 10 may also include a third antenna 19. The third antenna 19 may be located on the side frame 13B of the electronic device 10. The radio frequency signal source of the third antenna 19 is a third signal source, and the operating frequency of the third antenna 19 is a third frequency. The third antenna 19 may be a mid-to-high frequency antenna for cellular mobile communication, with a mid-to-high frequency range, for example, 1500MHz-2700MHz. The third frequency range may be the same as or different from the first frequency. When the third frequency is the same as the first frequency, the second frequency cannot be the same as the first frequency. The second antenna can isolate the first antenna and the third antenna. As shown in Figure 4A, the second antenna 18 may also include a grounding stub 25. The grounding stub 25 may also be an extension of the metal frame, extending inward to contact the grounding spring on the PCB floor, thereby improving the isolation between the first antenna 17 and the third antenna 19.

[0084] The third antenna 19 can be positioned close to the second antenna 18 so that the third antenna and the second antenna can be coupled together with the first antenna, becoming a parasitic antenna of the first antenna. "Close" means that the distance between them does not exceed a specific threshold. Here, distance can refer to the center distance, i.e., the distance between the center points of the two antenna radiators, or the distance between the nearest adjacent endpoints, or the distance measured by other methods.

[0085] The third antenna 19 can also be implemented as a frame antenna.

[0086] As shown in Figure 4A, the radiator of the third antenna 19 includes a first portion 22A of the side frame 13B. The first portion 22A of the side frame 13B can be the side frame portion on the second side of the slot 26, where the second side is the side of the side frame 13B facing away from the top corner 15A. The feed point 22B of the third antenna 19 can be located on the first portion 22A of the side frame 13B, and the feed point 22B is connected to the third signal source. A slot 27 can be provided on the first portion 22A, and a matching circuit can be loaded in the slot 27 to increase the electrical length of the third antenna 19.

[0087] As shown in Figure 4A, in the electronic device 10, the radiator 22A of the third antenna 19 can be connected to the third tuning switch 22C, which is used to adjust the resonant frequency of the third antenna 19. The third tuning switch 22C can be located close to the feed point 22C, or even both can be located on the same pad.

[0088] The third tuning switch 22C can have the following switching states: a third switching state and a fourth switching state. When the first antenna is working, the second and third antennas are not working. The second and third antennas can be used as parasitic antennas of the first antenna by combining the switching states of the third tuning switch 22C and the second tuning switch 21C. In this way, not only on the radiator 21A of the second antenna 18, but also on the radiator 22A of the third antenna 19, current near the first frequency will be distributed, and the radiation pattern of the first antenna 17 will cover a wider range, forming a wider beam.

[0089] Specifically, when the first antenna 17 is operating, the second tuning switch 21C is in the first switching state, and the third tuning switch 22C can be in the third switching state. A current near the first frequency is also distributed on the radiator 22A of the third antenna 19. When the first antenna 17 is operating, the second tuning switch 21C is in the second switching state, and the third tuning switch 22C is in the fourth switching state. No current near the first frequency is distributed on the radiator of the third antenna 19.

[0090] The first tuning switch 20C, the second tuning switch 21C, and the third tuning switch 22C can be single-pole multi-throw switches. They can be connected to a controller, such as a modem, to receive control signals from the controller and switch to different switching states.

[0091] Table 1 shows several switch combinations for these three tuning switches.

[0092] Table 1

[0093] In Table 1, SW1, SW2, and SW3 represent the first tuning switch 20C, the second tuning switch 21C, and the third tuning switch 22C, respectively. The columns for each switch, RF1, RF2, and RF3, indicate their respective switching states, corresponding to different stationary terminals of a single-pole multi-throw switch. The tuning switches tune their respective antennas to different frequencies by switching to different stationary terminals. Switching SW1 to RF1 or RF2 can be used to tune the first antenna to 1.9984 GHz and 2.185 GHz, respectively; switching SW2 to RF1, RF2, or RF3 can be used to tune the second antenna to 3.75 GHz, 1.85 GHz, and 2.392 GHz, respectively; and switching SW3 to RF1, RF2, or RF3 can be used to tune the third antenna to 2.185 GHz, 1.750 GHz, and 2.6 GHz, respectively.

[0094] TX1 and TX2 represent two different switch combinations when the first antenna transmits a signal, and RX1 and RX2 represent two different switch combinations when the first antenna receives a signal.

[0095] The switch combination state TX1 is as follows: SW1 is in the RF1 switch state, SW2 is in the RF2 switch state (belonging to the aforementioned first switch state), and SW3 is in the RF2 switch state (belonging to the aforementioned third switch state). At this time, SW1 is used to tune the resonant frequency of the first antenna to its transmission frequency of 1.9984 GHz, SW2 is used to tune the resonant frequency of the second antenna to 1.85 GHz, and SW3 is used to tune the resonant frequency of the third antenna to 1.75 GHz. Thus, the resonant frequencies of the second and third antennas are located near the transmission frequency of the first antenna, approximately 100 MHz lower, allowing the second and third antennas to function as parasitic antennas of the first antenna. At this time, currents near the satellite communication transmission frequency are distributed on the radiators of the second and third antennas, enabling satellite communication with a wide beam. The current distribution on each antenna stub is shown in Figure 7.

[0096] The switch combination state TX2 is as follows: SW1 is in the RF1 switch state, SW2 is in the RF1 switch state (belonging to the aforementioned second switch state), and SW3 is in the RF3 switch state (belonging to the aforementioned fourth switch state). At this time, SW1 is used to tune the resonant frequency of the first antenna to its transmission frequency of 1.9984 GHz, SW2 is used to tune the resonant frequency of the second antenna to 3.75 GHz, and SW3 is used to tune the third antenna to 1.75 GHz. The second and third antennas are not used as parasitic antennas of the first antenna, and no current near the satellite communication transmission frequency is distributed on the radiators of the second and third antennas. The current distribution on each antenna stub is shown in Figure 8.

[0097] The switch combination state RX1 is as follows: SW1 is in the RF2 switch state, SW2 is in the RF3 switch state (belonging to the aforementioned first switch state), and SW3 is in the RF1 switch state (belonging to the aforementioned third switch state). At this time, SW1 is used to tune the resonant frequency of the first antenna to its receiving frequency of 2.185 GHz, SW2 is used to tune the resonant frequency of the second antenna to 2.392 GHz, and SW3 is used to tune the resonant frequency of the third antenna to 2.185 GHz. Thus, the resonant frequency of the second antenna is located near the receiving frequency of the first antenna, approximately 200 MHz higher, and the second antenna can be used as a parasitic antenna for the first antenna. In Table 1, in RX1, the resonant frequency of the third antenna is tuned to equal the receiving frequency of the first antenna, and the third antenna can be used as another satellite communication receiving antenna to achieve dual satellite communication receiving antennas in the entire device together with the first antenna, improving signal reception efficiency. The resonant frequency of the third antenna can also be tuned to around 2.185 GHz, which is about 200 MHz higher than 2.185 GHz, such as 2.411 GHz. That is, like the second antenna, the third antenna can also be used as a parasitic antenna of the first antenna. In this case, the current distribution on each antenna branch is shown in Figure 14.

[0098] The switch combination state RX2 is as follows: SW1 is in the RF2 switch state, SW2 is in the RF1 switch state (belonging to the aforementioned second switch state), and SW3 is in the RF1 switch state (belonging to the aforementioned fourth switch state). At this time, SW1 is used to tune the resonant frequency of the first antenna to its receiving frequency of 2.185 GHz, SW2 is used to tune the resonant frequency of the second antenna to 3.75 GHz, and SW3 is used to tune the resonant frequency of the third antenna to 2.185 GHz. In Table 1, in RX2, the resonant frequency of the third antenna is tuned to equal the receiving frequency of the first antenna. The third antenna can be used as another satellite communication receiving antenna to achieve dual satellite communication receiving antennas in the entire device together with the first antenna, improving signal reception efficiency. The resonant frequency of the third antenna can also be tuned to a frequency far from the receiving frequency of the first antenna, meaning the third antenna can also be used without being a parasitic antenna of the first antenna. In this case, the current distribution on each antenna branch is shown in Figure 8.

[0099] In the example in Table 1, when the RX1 and RX2 combined switch is in the state, the third antenna can be used as another satellite communication receiving antenna, operating at the satellite communication receiving frequency. At this time, both the third antenna and the first antenna are connected to communication chips such as modems with dual receiving channels.

[0100] In this embodiment, when the first antenna is operational, the third antenna can also be used independently as a parasitic antenna for the first antenna, without requiring the third antenna to be used together with the second antenna as a parasitic antenna for the first antenna. In this case, the second antenna is not operational, but its resonant frequency does not need to be tuned to near the first frequency. This implementation places requirements on the distance between the third antenna and the first antenna. The signal conduction path length between the first and third antennas is less than a specific threshold. Specifically, the conduction path length from one end of the third antenna near slot 26 to one end of the first antenna near slot 25 is less than a specific threshold, such as 42 mm. This conduction path extends along the frame.

[0101] Figure 19 illustrates an example of antenna-related parameters. In the example of Figure 19, the corner frame is arc-shaped, and its conduction path length can be approximated by its lateral length x2 and longitudinal length y1. The length x1 of the radiator 20A of the first antenna can be approximately 29.4 mm, the width of the slot 25 (Gap1) can be approximately 0.8 mm, the width of the slot 26 (Gap2) can be approximately 1.1 mm, the lateral length x2 of the radiator 21A of the second antenna can be approximately 10 mm, the longitudinal length y1 of the radiator 21A of the second antenna can be approximately 13.7 mm, and the length of the radiator 22A of the third antenna can be 14.5 mm, i.e., y2 in Figure 19. As shown in Figure 19, the radiator 22A of the third antenna can also be longer, further including a side frame with a length of 14.8 mm on the other side of Gap3, and the width of Gap3 can be approximately 1 mm to 1.45 mm.

[0102] In this embodiment of the application, as shown in FIG20, a matching circuit connecting the second antenna 18 and the third antenna 19 can also be provided at the slot 26. This matching circuit can be used to block the signal current of the second frequency while allowing the signal current of the first frequency to pass through. In this way, when the third antenna and the second antenna are used as parasitic antennas of the first antenna, it can be ensured that the current near the first frequency is only excited on the third antenna, thereby improving the coverage of the radiation pattern.

[0103] Furthermore, to avoid hand-grip interference, the first, second, and third antennas can all be positioned in the upper half of the electronic device. Moreover, since the motherboard is generally stacked at the top of the device, placing them in the upper half can shorten the coaxial cables supplying power to the antennas, reducing path loss. Here, "upper half" refers to the part of the device closer to the top bezel, as opposed to the "lower half" closer to the bottom bezel; generally, it refers to the part of the device above the line connecting the midpoints of the two side bezels.

[0104] In the overall antenna design, as shown in Figure 4A, a slot 27 can be provided on the other side of the radiator 20A of the first antenna to isolate the first antenna from the fourth antenna in the electronic device 10. That is, a fourth antenna can also be provided at the top frame 13A, and the fourth antenna may include a radiator 23A and a feed point 23B disposed on the radiator 23A. The fourth antenna can be implemented as a multiplexed antenna for 5G Wi-Fi and N78. In practical applications, the operating frequency of the fourth antenna can be adjusted to the 5G Wi-Fi or N78 band by connecting a tuning switch to the fourth antenna. Not limited to a multiplexed antenna for 5G Wi-Fi and N78, the fourth antenna can also be implemented as other types of antennas, such as satellite navigation and positioning antennas, etc., and this application embodiment does not impose such limitations.

[0105] In addition, this application embodiment also provides a radiation pattern control method, which can be applied to the electronic device 10 provided in this application embodiment.

[0106] Figure 21 illustrates the overall flow of the direction pattern control method provided in the embodiments of this application. The details are as follows.

[0107] S51. The electronic device can initiate satellite communication and control the second tuning switch to be in the first switching state.

[0108] S52. During satellite communication, a change in the attitude of the electronic device is detected. When the first beam is pointed at the satellite, the electronic device can control the second tuning switch to be in a second switching combination state. The first beam can be the beam of the satellite communication signal when the second tuning switch is in the second switching state.

[0109] At the initial stage of satellite communication, the electronic device first sets the second tuning switch to the first switch state. This allows the second antenna to be used as a parasitic antenna for the first antenna, thus improving the radiation pattern coverage of the first antenna and achieving a wide-beam satellite communication antenna for easier satellite alignment. When the user adjusts the attitude of the electronic device to align with the satellite, if the first beam is found to be pointing towards the satellite, the second tuning switch is set to the second switch state. In this case, the second antenna is no longer used as a parasitic antenna for the first antenna, the first antenna beam narrows, and the antenna gain increases, which is beneficial to improving satellite call quality.

[0110] The first beam is the beam of the first antenna when the second antenna is not used as a parasitic antenna for the first antenna; it is a narrow beam. The direction of the first beam can be determined by the relative position of the electronic device and the satellite, as well as the beam angle of the first beam. Specifically, the electronic device can determine whether the first beam is pointing at the satellite based on its relative position and the beam angle. The relative position of the electronic device and the satellite can be determined based on satellite ephemeris data, while the beam angle can be determined based on the electronic device's position on Earth, its attitude, and the beam pattern. The electronic device's position on Earth can be detected using devices such as a compass or a Global Positioning System (GPS).

[0111] On the screen, the electronic device can display the satellite communication pairing status, as shown in Figure 24. The satellite identifier 61 indicates the direction of the satellite, and the fan-shaped area 62 represents the beam coverage direction of the first antenna. When the satellite identifier 61 falls within the fan-shaped area 62, it indicates successful pairing; when the satellite identifier 61 does not fall within the fan-shaped area 62, it indicates that pairing has not yet been successful.

[0112] Furthermore, when initiating satellite communication, the electronic device can control the third tuning switch to be in the third switching state, so that the third antenna is also used as a parasitic antenna of the first antenna at the beginning of satellite communication, thereby further improving the radiation pattern coverage of the first antenna and forming a wider beam. When a change in the attitude of the electronic device is detected during satellite communication, if the first beam is pointing towards the satellite, the second tuning switch is in the second switching combination state, and the electronic device can also control the third tuning switch to be in the fourth switching state. In this way, the second and third antennas are no longer used as parasitic antennas of the first antenna, the beam of the first antenna becomes narrower, the antenna gain becomes stronger, which is beneficial to improving the quality of satellite communication.

[0113] Satellite communication can include signal transmission and signal reception. During the signal transmission phase (uplink phase) of satellite communication, electronic equipment can control a first tuning switch to tune the resonant frequency of the first antenna to the transmission frequency of the first antenna; during the signal reception phase (downlink phase) of satellite communication, the first tuning switch is controlled to tune the resonant frequency of the first antenna to the reception frequency of the first antenna.

[0114] Furthermore, before determining whether the first beam is pointing at the satellite, the electronic device can also determine that the second beam is pointing at the satellite. The second beam is the satellite communication beam when the second tuning switch is in the first switch combination state. In this way, after determining that the wide beam (second beam) is pointing at the satellite, the decision to switch to the narrow beam (first beam) can be made, thus saving processing steps.

[0115] As shown in Figure 22, in addition to the antenna described in the above embodiments, the electronic device provided in this application embodiment may also include: a processor 110, a memory 120, a display 130, a display driver integrated circuit (DDIC) 140, a communication module 160, an audio module 170, a speaker 170A, a receiver 170B, a microphone 170C, a headphone jack 170D, a sensor module 180, buttons 190, a motor 191, an indicator 192, a camera 193, etc. The sensor module 180 may include a gyroscope sensor 180B, an accelerometer sensor 180E, and a touch sensor 180K, etc. The various parts of the electronic device 300 can be connected via a bus.

[0116] The processor 110 provides computing power and can be used as the computing module of the electronic device 300. Input / output components such as the display 130, audio module 170, speaker 170A, receiver 170B, microphone 170C, headphone jack 170D, sensor module 180, buttons 190, motor 191, indicator 192, and camera 193 provide human-computer interaction capabilities and can be used as the human-computer interaction module of the electronic device 300. There can be one or more processors 110, which can be integrated into a system-on-a-chip (SOC). An SOC is a system-on-a-chip.

[0117] The processor 110 may include an application processor (AP), a baseband processor (BP), etc. The AP is responsible for running the operating system, user interface, and applications on the electronic device 300; the BP is responsible for transmitting and receiving wireless signals and managing radio frequency services.

[0118] The memory 120 may include a program storage area and a user data storage area. The program storage area may store the operating system and one or more application programs, while the data storage area may store data created by the user during the use of the electronic device 300. The memory 120 may be a high-speed random access memory or a non-volatile memory, such as a hard disk, flash memory, or universal flash storage (UFS). The memory 120 may also be an external memory card, such as a Micro SD card.

[0119] The memory 120 may also store a computer program for the image editing method provided in the embodiments of this application. When the processor 110 reads the computer program from the memory 120 and runs the computer program, the electronic device 300 may execute the directional control method provided in the embodiments of this application.

[0120] Communication module 160 may include a satellite communication module, a cellular mobile communication module, a sub-6G FR1 communication module, etc., which can be coupled to their respective antennas. The satellite communication module is coupled to the first antenna, the cellular mobile communication module is coupled to the third antenna, and the sub-6G FR1 communication module is coupled to the second antenna. The satellite communication module may consist of filters, switching circuits, power amplifiers, modems, etc. The modem is used to modulate the low-frequency baseband signal to be transmitted into a mid-to-high frequency signal. The demodulator is used to demodulate the received electromagnetic wave signal into a low-frequency baseband signal. The demodulator then transmits the demodulated low-frequency baseband signal to the baseband processor for processing. After processing by the baseband processor, the low-frequency baseband signal is transmitted to the application processor. The application processor outputs sound signals through the audio module and / or displays images or videos through the display.

[0121] In addition, electronic devices may also include wireless local area networks (WLAN) (such as wireless fidelity (Wi-Fi) networks), Bluetooth (BT), global navigation satellite system (GNSS), near field communication (NFC), infrared (IR) and other wireless communication modules and their respective antennas.

[0122] The structure illustrated in Figure 22 does not constitute a specific limitation on the electronic device. An electronic device may include more or fewer parts than illustrated, or combine or separate certain parts, or arrange different parts. The various parts illustrated may be implemented in hardware, software, or a combination of both.

[0123] At the software system level of the electronic device, a specific implementation of the radiation pattern control method provided in this application embodiment is shown in Figure 23. In Figure 23, "satellite_service" represents a satellite communication application or service, which can start or stop satellite communication according to user operation, and can also display the user interface shown in Figure 24; "ril_adapter_ext" represents the service interface layer of the modem, and the application layer can control the modem operation by calling its interface; "modem" represents the modem. The radiation pattern control method executed by the electronic device can be completed by these modules cooperating with each other. The following is a further explanation:

[0124] S61. In response to the user initiating a satellite call, the electronic device may begin parsing the configuration file to determine the initial switch combination state for satellite communication. This switch combination state may be the switch combination state of the first tuning switch and the second tuning switch, or the switch combination state of the first tuning switch, the second tuning switch, and the third tuning switch.

[0125] For example, an electronic device can begin parsing a configuration file via a satellite communication application to determine the initial switch combination state for satellite communication. This switch combination state can be a combination of the first and second tuning switches, or a combination of the first, second, and third tuning switches.

[0126] The configuration file can be used to record all switch combinations of the first, second, and third tuning switches when the first antenna transmits a signal, and all switch combinations of the first, second, and third tuning switches when the first antenna receives a signal. The configuration file can be, for example, as shown in Table 1 above.

[0127] As for which switch combination state from the configuration file is used at the beginning of satellite communication, this can be recorded in the first parameter. For example, the first parameter can be the parameter `satantstatesel`.

[0128] S62. The electronic device can set a first parameter and a second parameter, wherein the first parameter is used to indicate the switch combination state to be used for satellite communication, and the second parameter is used to configure the antenna reporting cycle.

[0129] For example, an electronic device can transmit a first parameter and a second parameter to a first module via a satellite communication application.

[0130] For example, the first module can be the ril_adapter_ext module, and the second parameter can be the satantrpt parameter.

[0131] S63-S64. The electronic device can set the initial switching state of the tuning switches of each antenna according to the first parameter and the second parameter, and enable antenna status reporting, so that the second antenna and the third antenna are coupled to the first antenna, thereby giving the first antenna a wide beam. The modem can report the antenna status of the satellite communication antenna to the satellite communication application through antenna status reporting.

[0132] For example, after receiving the first parameter and the second parameter, the electronic device can control the modem through the first module to set the initial switching state of the tuning switches of each antenna, and to control the modem to enable antenna status reporting. In response to the control action of the first module, the modem sets the initial switching state of the tuning switches of each antenna.

[0133] S65. The electronic device can detect changes in the posture of the electronic device and decide whether to switch the state of the switch combination.

[0134] For example, an electronic device can detect changes in its attitude via a satellite communication application and decide whether to switch the combination state.

[0135] Specifically, the electronic device can determine whether the first beam is pointing at the satellite based on its relative position to the satellite and the beam angle of the first beam. If the first beam is pointing at the satellite, it will decide to switch the combination state of the switches. Here, the switching may include: switching the second tuning switch to the second switch state, or switching the switching states of the second tuning switch and the third tuning switch to the second switch state and the third switch state, respectively.

[0136] S66. When it is necessary to switch the combination state of the switches, the electronic device can update the first parameter.

[0137] For example, the electronic device can transmit the updated first parameter to the first module via a satellite communication application.

[0138] S67-S68. Electronic devices can change the switch combination state according to the updated first parameter.

[0139] For example, the electronic device can control the modem to change the switching combination state according to the updated first parameter via the first module. The modem can switch the switching combination state according to the control action of the first module, so that the second antenna and the third antenna are no longer coupled to the first antenna, thereby changing the radiation pattern of the first antenna and improving the signal gain of the first antenna.

[0140] S69. In response to the user turning off satellite communication, the electronic device may update a second parameter, which is used to indicate the reporting of the antenna off status.

[0141] For example, the electronic device can transmit the updated second parameter to the first module via a satellite communication application.

[0142] S70. Electronic devices can disable antenna status reporting.

[0143] For example, an electronic device can control a modem to disable antenna status reporting via a first module.
