Abstract
Description
Technical Field
[0001] The present application relates to the field of antenna technology, and in particular to antenna devices and electronic equipment. Background Art
[0002] In satellite communications, signals experience significant transmission losses during space propagation, so satellite antennas must possess strong directivity and high signal gain to ensure communication quality. The design of high-gain satellite antennas for portable electronic devices such as mobile phones is a significant concern in this field. Mobile phones and other portable electronic devices contain various components, including screens, batteries, and camera modules, leaving very limited space for antenna design. This poses a challenge to the design of satellite antennas for mobile phones. Summary of the Invention
[0003] In a first aspect, an embodiment of the present application provides 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 being connected to form a first corner, and the second frame extending in a different direction from the first frame.
[0004] The first antenna may be disposed at a first border of the electronic device, and the second antenna may be disposed at a first corner;
[0005] The radio frequency signal source of the first antenna is a first signal source, and the operating frequency of the first antenna is a first frequency; the radio frequency signal source of the second antenna is a second signal source, and the operating frequency of the second antenna is a second frequency;
[0006] 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: a first switching state and a second switching state, wherein 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, and 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.
[0007] Thus, when the second tuning switch is switched to the first switching state, in addition to the current of the emission frequency being distributed on the radiator of the first antenna,
[0008] The second antenna's radiator also carries a current near its transmit frequency. In this case, the second antenna acts as a parasitic antenna for the first antenna, allowing the first antenna's radiation pattern to cover a wider range and form a wide beam, making it easier for users to aim at the satellite. However, when the second tuning switch is switched to the second switching state, the first antenna's radiator carries a current at its transmit frequency, but no current near the first antenna's transmit frequency is distributed on the second antenna's radiator. In this case, the second antenna is not acting as a parasitic antenna for the first antenna. The first antenna's current is distributed only on its own radiator. The first antenna's radiation pattern covers a narrower range, resulting in a narrower beam. However, the antenna gain is increased, resulting in better signal quality.
[0009] In the first aspect, the first antenna may be a satellite communication antenna, and the second antenna may be a sub 6G Class 1 (FR1) operating frequency band antenna.
[0010] In conjunction with the first aspect, in some embodiments, the first angle is the angle closest to the first antenna among the multiple angles, which facilitates coupling of the first antenna to the second antenna. Here, the distance can refer to the 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 metrics.
[0011] In combination with the first aspect, in some embodiments, the electronic device may further include a third antenna and a third tuning switch, and the third antenna may be provided at the second frame. The RF 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 the first switching state, the third tuning switch may be in the third switching state, and a current near the first frequency is also distributed on the radiator of the third antenna; when the first antenna is operating, the second tuning switch may be in the second switching state, the third tuning switch may be in the fourth switching state, and no current near the first frequency is distributed on the radiator of the third antenna. In this way, the current distribution on the antenna branches can be changed by controlling the switching states of the second tuning switch and the third tuning switch 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. Alternatively, the third antenna and the second antenna may not be used as parasitic antennas of the first antenna to narrow the signal beam of the first antenna, thereby improving the antenna gain.
[0012] The third antenna may be a medium or high frequency antenna for cellular mobile communications.
[0013] In conjunction with the first aspect, in some embodiments, the first antenna and the second antenna can be implemented as frame antennas, that is, the conductive frame of the electronic device is used as the radiator of the first antenna and the second antenna. 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 can include a first portion of the first frame, which can be located on a first side of the first slit, where the first side is the side of the first frame facing away from the first corner. The radiator of the second antenna includes the frame between the first slit and the second slit.
[0014] In conjunction with the first aspect, in some embodiments, the third antenna may also be implemented as a frame antenna. The radiator of the third antenna may include a first portion of the second frame, the first portion of the second frame being located on a second side of the second slot, the second side being the side of the second frame facing away from the first corner.
[0015] In combination with the first aspect, in some embodiments, the feeding point of the first antenna is disposed on the radiator of the first antenna. To enhance coupling to the second antenna, the distance between the feeding point of the first antenna and the first slot is less than a preset distance value.
[0016] In combination with the first aspect, in some embodiments, a matching circuit connecting the second antenna and the third antenna is provided at the second slot, and the matching circuit is configured to pass a signal current of the first frequency and block a signal current of the second frequency.
[0017] In conjunction with the first aspect, in some embodiments, the first frequency may include a transmit frequency and a receive frequency of the first antenna. The first tuning switch may be used to tune the resonant frequency of the first antenna to the transmit frequency or the 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 impact of hand-holding, the first antenna, second antenna, and third antenna can all be arranged in the upper half of the electronic device. Moreover, since the motherboard is generally stacked on the upper part of the device, their placement in the upper half of the device can also shorten the coaxial cable feeding the antenna and reduce path loss. Here, the upper half refers to the part of the device closer to the top frame, relative to the lower half closer to the bottom frame, and generally refers to the part of the device above the line connecting the midpoints of the two side frames.
[0019] In a second aspect, embodiments of the present application provide a pattern control method, which can be applied to an electronic device, which may be the electronic device described in the first aspect. The method may include: initiating satellite communication, controlling a second tuning switch to a first switching state; and, upon detecting a change in the posture of the electronic device during satellite communication, controlling the second tuning switch to a second switching state when the first beam is directed toward 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 method provided in the second aspect can initially set the second tuning switch to the first switch state upon initiating satellite communications, enabling the second antenna to function as a parasitic antenna for the first antenna, improving the first antenna's directional coverage and achieving a wide-beam satellite communications antenna to facilitate user alignment. When the user adjusts the electronic device's posture for alignment, if the first beam is pointed toward the satellite, the second tuning switch is set to the second switch state. This eliminates the second antenna's function as a parasitic antenna for the first antenna, narrows the first antenna's beam, and increases antenna gain, thereby 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 of the first antenna, and 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, and the beam angle of the first beam. Specifically, the electronic device can determine whether the first beam is pointing to the satellite based on the relative position of the electronic device and the satellite, and the beam angle of the first beam. The relative position of the electronic device and the satellite can be determined based on satellite ephemeris data, and the beam angle of the first beam can be determined based on the position of the electronic device on the earth, the posture of the electronic device, and the directional pattern of the first beam. The position of the electronic device on the earth can be detected by devices such as a compass and a global positioning system (GPS).
[0022] In combination with the second aspect, in some embodiments, the method may further include: when the second tuning switch is in the first switching state, also controlling the third tuning switch to be in the third switching state, so that the third antenna is also used as the parasitic antenna of the first antenna at the beginning of the satellite communication, so as to further improve the directional pattern coverage of the first antenna and form a wider beam; when the posture of the electronic device is detected to change during satellite communication, when the first beam points to the satellite, the third tuning switch is also controlled to be in the fourth switching state.
[0023] In combination with the second aspect, in some embodiments, the method may also include: in the uplink phase of satellite communication, controlling the first tuning switch to tune the resonant frequency of the first antenna to the transmitting frequency; in the downlink phase of satellite communication, controlling the first tuning switch to tune the resonant frequency of the first antenna to the receiving frequency, the second antenna and the third antenna are no longer used as parasitic antennas of the first antenna, the beam of the first antenna becomes narrower, and the antenna gain becomes stronger, which is beneficial to improving the quality of satellite calls.
[0024] In combination with the second aspect, in some embodiments, before controlling the second tuning switch to be in the second switch state, it also includes: judging whether the first beam is pointing to 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 the satellite ephemeris data, and the beam angle of the first beam is determined based on the position of the electronic device on the earth, the posture of the electronic device, and the directional pattern of the first beam.
[0025] In conjunction with the second aspect, in some embodiments, before determining whether the first beam is directed toward a satellite, the electronic device may also determine that the second beam is directed toward the satellite, where 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 directed toward the satellite, whether to switch to the narrow beam (first beam) can be considered, thereby reducing processing steps.
[0026] In a third aspect, an embodiment of the present application further provides a computer-readable storage medium having a computer program stored thereon. When the computer program is executed by a processor, the steps of the directional pattern control method described in the second aspect can be implemented.
[0027] In a fourth aspect, an embodiment of the present application further provides a computer program, which, when executed by a processor, can implement the steps of the directional pattern control method described in the second aspect. BRIEF DESCRIPTION OF THE DRAWINGS

[0054] The terms used in the following embodiments of the present application are only for the purpose of describing specific embodiments and are not intended to limit the present application.
[0055] Figure 1 A design scheme of satellite communication antenna is shown. Figure 1As shown, in this design, the satellite communication antenna radiator is set on the top of the mobile phone, with both ends of the radiator open. A feed point is set at position A near one end, a ground point is set at position B in the middle of the radiator, and a tuning switch SW is set at position A' between positions A and B. The tuning switch SW is connected to a communication module such as a modem so that it can be controlled by the modem to change the switch state, thereby adjusting the resonant frequency of the antenna. When Beidou satellite navigation is not turned on, the tuning switch defaults to the Global Positioning System (GPS) optimal state, causing the satellite antenna to resonate in the GPS satellite navigation frequency band. When Beidou satellite navigation is turned on, 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. In this way, the performance of Beidou satellite navigation and GPS satellite navigation can be improved.
[0056] but, Figure 1 The satellite communication antenna shown is a satellite navigation and positioning antenna and is not suitable for satellite calling. Its narrow radiation pattern makes it difficult to point to the satellite. Satellite navigation primarily focuses on navigation and positioning. While it can also be used to send and receive text messages, current satellite navigation technology does not support the ability to edit text messages, limiting users to pre-set messages. Satellite calling, on the other hand, offers a more powerful communication capability, allowing users to make voice calls in areas without terrestrial signal coverage and send and receive freely editable text messages. Satellite communication antennas require high-gain, wide-beam antennas.
[0057] The embodiments of the present application will provide an antenna design solution that can be applied to satellite call scenarios of electronic devices such as mobile phones. By making full use of the antenna distribution of the entire device, a high-gain wide-beam satellite communication antenna can be designed within the limited clearance within the electronic device.
[0058] Figure 2 FIG. 1 shows an electronic device 10 provided in an embodiment of the present application. Figure 2 As shown, the electronic device 10 may include a screen 11 and a back cover arranged opposite to the screen 11. Figure 2 In the embodiment, the back cover is not visible because it is behind the screen 11.
[0059] The electronic device 10 may also include multiple frames, such as frame 13A, frame 13B, frame 13C and frame 13D. These multiple frames are connected end to end to enclose 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 frames, two adjacent frames with different extension directions are connected to each other to form multiple corners of the electronic device 10, such as corner 15A, corner 15B, corner 15C and corner 15D. Figure 2 In the figure, corner 15A is formed by connecting the horizontally extending frame 13A and the vertically extending frame 13B, corner 15B is formed by connecting the horizontally extending frame 13A and the vertically extending frame 13D, corner 15C is formed by connecting the vertically extending frame 13D and the horizontally extending frame 13C, and corner 15D is formed by connecting the vertically extending frame 13B and the horizontally extending frame 13C.
[0060] A corner is a position range, such as Figure 3 As shown, it may include two connected contact segments forming a corner, such as 21A and 21B, and a semi-enclosed area 22 ( Figure 3 The size of the turning angle depends on the length of 21A and the length of 21B, which can be determined according to actual application requirements and is not limited in this embodiment of the present application.
[0061] Depending on their respective positions in the electronic device, frame 13A can be called the top frame, frame 13C can be called the bottom frame, and frame 13B and frame 13D can be called side frames. Corners 15A and 15B can be called top corners, and corners 15C and 15D can be called bottom corners. The transition portion where the side frame connects to the top frame can be called the top corner frame, and the transition portion where the side frame connects to the bottom frame can be called the bottom corner frame. The top and bottom directions are for vertical screen usage scenarios. In the vertical screen usage scenario of the electronic device 10, the top is the end of the device facing upward (toward the sky), and the bottom is the end of the device facing downward (toward the ground). The top of the electronic device 10 can be provided with devices such as a noise reduction microphone (not shown), a camera (not shown), an earpiece (not shown), and a proximity light sensor (not shown); the bottom of the electronic device 10 can usually be provided with a main microphone (not shown), a USB charging port (not shown), etc. The side of the electronic device can be provided with a volume adjustment button (not shown) and a power button (not shown).
[0062] like Figure 2 As shown, the electronic device 10 may further include a first antenna 17 and a second antenna 18 . Figure 2The antennas are briefly illustrated in dashed boxes. First antenna 17 can be located at top frame 13A of electronic device 10, and second antenna 18 can be located at top corner 15A. Top corner 15A can be the corner closest to first antenna 17 among the multiple corners of electronic device 10, which facilitates coupling of first antenna 17 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 a distance measured using other metrics.
[0063] The RF signal source of the first antenna 17 is the first signal source, and the operating frequency of the first antenna 17 is the first frequency. The RF signal source of the second antenna 18 is the second signal source, and the operating frequency of the second antenna 18 is the second frequency. The first antenna 17 can be a satellite communication antenna, and the second antenna 18 can be a sub 6G type of operating frequency band (FR1) antenna, such as a multiplexing antenna of N79 (4.4GHz-5.0GHz) and N78 (3.3GHz-3.8GHz). When the second antenna is working, the operating frequency of the second antenna can be adjusted to N79 or N78 through the tuning switch. The operating frequency of the antenna refers to the frequency range of the antenna for receiving and transmitting electromagnetic waves, usually expressed in Hertz (Hz). It can be a single frequency or a continuous frequency within a certain range. Different types of antennas correspond to different operating frequencies. The first antenna 17 and the second antenna 18 belong to different types of antennas.
[0064] The first antenna 17 and the second antenna 18 can be implemented as frame antennas, such as 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 The principle structure of the first antenna 17 and the second antenna 18 implemented based on the frame is briefly shown.
[0066] like Figure 4AAs shown, the top frame 13A and the side frame 13B are connected at the top corner. A slit 25 may be provided on the top frame 13A, and a slit 26 may be provided on the side frame 13B. The slit 25 may be the slit closest to the first frame connection point on the top frame 13A, and the slit 26 may be the slit closest to the first frame connection point on the side frame 13B. The first frame connection point refers to the connection point between the side frame 13B and the top frame 13A. It is a positional concept and does not require that the side frame 13B and the top frame 13A be connected here in the process. The entire peripheral conductive frame can be integrally formed, and no connection point may be generated in the process. The radiator of the first antenna 17 may include the first part 20A of the top frame 13A. The first part 20A of the top frame 13A is the top frame part on the first side of the slit 25. Here, the first side is the side of the top frame 13A that is away from the top corner 15A. The radiator of the second antenna 18 may include a frame section 21A between the slot 25 and the slot 26 , where the frame section 21A is a top corner frame.
[0067] The feeding point 20B of the first antenna 17 can be set on the first part 20A, and the feeding point 20B is connected to the first signal source. The feeding point 21B of the second antenna 18 can be set on the frame 21A, and the feeding point 21B is connected to the second signal source. In order to enhance the coupling effect on the second antenna 18, the feeding point 20B of the first antenna 17 can be set close to the slot 25, and the distance between the two is less than a preset distance value, for example, the distance from the feeding point 20B to the slot 25 is within 10 mm. The example is only used to explain the embodiments of the present application, and may be different in actual applications and should not constitute a limitation.
[0068] like Figure 4A As shown, in electronic device 10, radiator 20A of first antenna 17 can be connected to a first tuning switch 20C, and radiator 21A of second antenna 18 can be connected to a second tuning switch 21C. First tuning switch 20C is used to adjust the resonant frequency of first antenna 17, and second tuning switch 21C is used to adjust the resonant frequency of second antenna 18.
[0069] The first tuning switch 20C can be located close to the feeding point 20B, i.e. the distance between the two is less than a preset distance value (e.g. 3 mm). The two can even be located on the same connecting piece (pad). The connecting piece (pad) can be an extension of the metal frame, which extends inward to contact the metal spring on the PCB, thereby forming an electrical connection with the feed source, tuning switch circuit, etc. on the PCB. In order to distinguish the first tuning switch 20C from the feeding point 20B, Figure 4A It is shown that the first tuning switch 20C and the feeding point 20B are respectively arranged on two connecting pieces. However, in actual application, the two can share one connecting piece and be respectively connected to the feed source and the tuning switch circuit on the PCB.
[0070] The second tuning switch 21C can be located close to the feeding point 21B, and the two can even 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. In this way, 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 the radiation pattern of the first antenna 17. When the first antenna 17 is operating at the first frequency, the second antenna 18 can be inoperative. Here, the inoperative state of the second antenna 18 means that the signal transceiver circuit of the second antenna 18 is inoperative, for example, by disconnecting the path between the second antenna 18 and its signal transceiver circuit.
[0072] The first frequency may include the transmit frequency and receive frequency of the first antenna 17. The first tuning switch 20C may be configured to switch the resonant frequency of the first antenna 17 between the transmit frequency and the receive frequency. The first tuning switch 20C may be connected to a controller, such as a modem. When the first antenna 17 is used for signal reception, the controller may control the first tuning switch 20C to adjust the resonant frequency of the first antenna 17 to the receive frequency; when the first antenna 17 is used for signal transmission, the controller may control the first tuning switch 20C to adjust the resonant frequency of the first antenna 17 to the transmit frequency.
[0073] The first antenna 17 may be a satellite communication antenna, the transmitting frequency of which may be, for example, 1980 MHz-2010 MHz, and the receiving frequency of which may be, for example, 2170 MHz-2200 MHz.
[0074] Below, the first antenna 17 is a satellite communication antenna as an example. Figure 5-Figure 11 and Figures 12-18 How different switch states of the second tuning switch 21C affect the signal transmission and signal reception of the first antenna 17 is described respectively.
[0075] Figure 5-Figure 6 The comparison shows the changes in simulation results caused by the second tuning switch 21C being in different switch states when the first antenna 17 transmits a signal. Figure 5 Specifically shown is the simulation result of the first antenna 17 when the second tuning switch 21C is switched to the first switch state. Figure 6Specifically shown are simulation results for first antenna 17 when second tuning switch 21C is switched to the second switching state. It can be seen that by switching second tuning switch 21C to the first switching state, a resonance point A is created approximately 100 MHz ahead of the satellite communication transmission resonance point (1.9984 GHz). This resonance point is approximately 100 MHz lower than the satellite communication transmission resonance point. This resonance point is generated by coupling second antenna 18 to first antenna 17, and its frequency is near the transmission frequency of first antenna 17.
[0076] Figure 7-Figure 8 The comparison shows the current distribution changes caused by the second tuning switch 21C being in different switch states when the first antenna 17 transmits a signal, and the arrows indicate the current direction. Figure 7 Specifically shown is the current distribution on the antenna branch when the second tuning switch 21C is switched to the first switch state. Figure 8 Specifically shown is the current distribution on the antenna branch when the second tuning switch 21C is switched to the second switch state.
[0077] like Figure 7-Figure 8 As shown, when the second tuning switch 21C is switched to the first switching state, in addition to the current at the transmit frequency of the first antenna 17 flowing through the radiator, the current near its transmit frequency also flows through the radiator of the second antenna 18. In this case, the second antenna 18 acts as a parasitic antenna for the first antenna 17, so that the radiation pattern of the first antenna 17's signal covers a wider range, forming a wide beam, facilitating user alignment. However, when the second tuning switch 21C is switched to the second switching state, the current at the transmit frequency of the first antenna 17 flows through the radiator of the second antenna 18, but no current near the transmit frequency of the first antenna 17 flows through the radiator of the second antenna 18. In this case, the second antenna 18 is not used as a parasitic antenna for the first antenna 17. The current flowing through the first antenna 17 flows only through the radiator of the first antenna 17. The radiation pattern of the first antenna 17's signal covers a narrower range, resulting in a narrower beam. However, 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, Figure 10 1 shows the transmission pattern data of the first antenna 17 when the second tuning switch 21C is in the second switch state. Figure 11 Also shown Figure 10 The pattern data shown is relative to Figure 9 The directional pattern data shown shows the directional pattern gain. It can be seen that within the observation angle range of theta 40 to 60 degrees and phi 110 to 220 degrees, Figure 8 The value in the indicator indicates that the signal gain has increased. Figures 9-11The unit of the value is dB.
[0079] Figure 12-13 The comparison shows the changes in simulation results caused by the second tuning switch 21C being in different switch states when the first antenna 17 receives the signal. Figure 12 Specifically shown is the simulation result of the first antenna 17 when the second tuning switch 21C is switched to the first switch state. Figure 13 Specifically shown are simulation results for first antenna 17 when second tuning switch 21C is in the second switching state. It can be seen that by switching second tuning switch 21C to the first switching state, a resonance point B is created approximately 200 MHz behind the satellite call signal reception resonance point (2.2065 GHz). This resonance point is approximately 200 MHz higher than the satellite call signal reception resonance point. This resonance point is generated by coupling second antenna 18 to first antenna 17, and its frequency is near the reception frequency of first antenna 17.
[0080] Figure 14-15 The comparison shows the current distribution changes caused by the second tuning switch 21C being in different switch states when the first antenna 17 receives the signal, and the arrows indicate the current direction. Figure 14 Specifically shown is the current distribution on the antenna branch when the second tuning switch 21C is switched to the first switch state. Figure 15 Specifically shown is the current distribution on the antenna branch when the second tuning switch 21C is switched to the second switch state.
[0081] like Figure 14-15 As shown, when the second tuning switch 21C is switched to the first switching state, in addition to the current at the receiving frequency of the first antenna 17 flowing through the radiator, the radiator of the second antenna 18 also flows through a current near the receiving frequency of the first antenna 17. In this case, the second antenna 18 acts as a parasitic antenna for the first antenna 17, allowing the radiation pattern of the first antenna 17 to cover a wider range and form a wider beam, facilitating user alignment. However, when the second tuning switch 21C is switched to the second switching state, the current at the receiving frequency of the first antenna 17 flows through the radiator of the second antenna 18, but no current near the receiving frequency of the first antenna 17 flows through the radiator of the second antenna 18. In this case, the second antenna 18 is not used as a parasitic antenna for the first antenna 17. The current of the first antenna 17 flows only through the radiator of the first antenna 17. The radiation pattern of the first antenna 17's radiation signal covers a narrower range and forms a narrower beam, but the antenna gain is improved, resulting in better signal quality.
[0082] Figure 16 shows the receiving pattern data of the first antenna 17 when the second tuning switch 21C is in the first switch state, Figure 171 shows the reception pattern data of the first antenna 17 when the second tuning switch 21C is in the second switch state. Figure 18 Also shown Figure 16 The pattern data shown is relative to Figure 17 The directional pattern data shown shows the directional pattern gain. It can be seen that within the observation angle range of theta 25 to 60 degrees and phi 60 to 220 degrees, Figure 16 The value in the indicator indicates that the signal gain has increased. Figure 16-18 The unit of the value is dB.
[0083] Further, such as Figure 2 As shown, the electronic device 10 may further include a third antenna 19. The third antenna 19 may be provided 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 medium-high frequency antenna for cellular mobile communications, and the medium-high frequency range may be, 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, and the second antenna may serve to isolate the first antenna and the third antenna. As shown Figure 4A As shown, the second antenna 18 may further include a grounding branch 25 , which may also be an extension of the metal frame, extending inward to contact the ground return spring on the PCB floor to help improve 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, allowing the third antenna and the second antenna to couple to the first antenna, acting as parasitic antennas of the first antenna. Close proximity means that the distance between the two antennas does not exceed a specific threshold. Here, distance can refer to center-to-center distance (i.e., the distance between the center points of the two antenna radiators), the distance between the nearest adjacent endpoints, or a distance measured using another metric.
[0085] The third antenna 19 may also be implemented as a frame antenna.
[0086] like Figure 4A As shown, the radiator of the third antenna 19 includes a first portion 22A of the side frame 13B. This first portion 22A of the side frame 13B can be the portion of the side frame 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. A feed point 22B for the third antenna 19 can be provided on the first portion 22A of the side frame 13B and connected to a third signal source. A slot 27 can be provided on the first portion 22A, and a matching circuit can be incorporated into the slot 27 to increase the electrical length of the third antenna 19.
[0087] like Figure 4A As shown, in the electronic device 10, the radiator 22A of the third antenna 19 can be connected to the third tuning switch 22C, and the third tuning switch 22C is used to adjust the resonant frequency of the third antenna 19. The third tuning switch 22C can be provided close to the feeding point 22C, and the two can even be provided on the same pad.
[0088] The third tuning switch 22C can have the following switch states: a third switch state and a fourth switch state. When the first antenna is operating, the second and third antennas are inoperative. By controlling the switch states of the third tuning switch 22C in combination with the second tuning switch 21C, the second and third antennas can be used as parasitic antennas for the first antenna. This allows current near the first frequency to flow not only along the radiator 21A of the second antenna 18 but also along the radiator 22A of the third antenna 19. This allows the radiation pattern of the first antenna 17 to 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, the third tuning switch 22C can be in the third switching state, and a current near the first frequency is 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, and 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 may be single-pole multi-throw switches and may be connected to a controller, such as a modem, to receive a control signal from the controller and switch to different switch states.
[0091] Table 1 shows several switch combination states of the three tuning switches.
[0092] frequency band SW1 SW2 SW3 TX1 RF1 RF2 RF2 TX2 RF1 RF1 RF3 RX1 RF2 RF3 RF1 RX2 RF2 RF1 RF1
[0093] Table 1
[0094] 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. RF1, RF2, and RF3 in the columns corresponding to each switch indicate their respective switch states, corresponding to different fixed terminals of a single-pole, multi-throw (SPMT) switch. The tuning switches are switched to different fixed terminals to tune the antennas to different frequencies. Switching SW1 to RF1 or RF2 tunes the first antenna to 1.9984 GHz or 2.185 GHz, respectively. Switching SW2 to RF1, RF2, or RF3 tunes the second antenna to 3.75 GHz, 1.85 GHz, or 2.392 GHz, respectively. Switching SW3 to RF1, RF2, or RF3 tunes the third antenna to 2.185 GHz, 1.750 GHz, or 2.6 GHz, respectively.
[0095] TX1 and TX2 represent two different switch combination states when the first antenna transmits a signal, and RX1 and RX2 represent two different switch combination states when the first antenna receives a signal.
[0096] The switch combination state TX1 is: 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 1.9984GHz, SW2 is used to tune the resonant frequency of the second antenna to 1.85GHz, and SW3 is used to tune the resonant frequency of the third antenna to 1.75GHz. In this way, the resonant frequencies of the second and third antennas are near the transmission frequency of the first antenna, which is about 100MHz lower than the transmission frequency. The second and third antennas can be used 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, and the satellite communication has a wide beam. The current distribution on each antenna branch is as follows: Figure 7 shown.
[0097] The switch combination state TX2 is: 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 1.9984GHz, SW2 is used to tune the resonant frequency of the second antenna to 3.75GHz, and SW3 is used to tune the third antenna to 1.75GHz. 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 branch is as follows: Figure 8 shown.
[0098] The switch combination state RX1 is: 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 2.185GHz, SW2 is used to tune the resonant frequency of the second antenna to 2.392GHz, and SW3 is used to tune the resonant frequency of the third antenna to 2.185GHz. In this way, the resonant frequency of the second antenna is near the receiving frequency of the first antenna, which is approximately 200MHz higher than the receiving frequency. The second antenna can be used as a parasitic antenna of the first antenna. In Table 1, in RX1, the resonant frequency of the third antenna is tuned to be equal to the receiving frequency of the first antenna. The third antenna can be used as another satellite communication receiving antenna to realize a satellite communication dual receiving antenna in the whole device together with the first antenna, thereby 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. At this time, the current distribution on each antenna branch is as follows: Figure 14 shown.
[0099] The switch combination state RX2 is: 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 2.185GHz, SW2 is used to tune the resonant frequency of the second antenna to 3.75GHz, and SW3 is used to tune the resonant frequency of the third antenna to 2.185GHz. In Table 1, during RX2, the resonant frequency of the third antenna is tuned to be equal to the receiving frequency of the first antenna. The third antenna can be used as another satellite communication receiving antenna to realize the satellite communication dual receiving antenna in the whole machine together with the first antenna, thereby improving the signal reception efficiency. The resonant frequency of the third antenna can also be tuned to a receiving frequency far away from the first antenna, that is, the third antenna can also be used as a parasitic antenna instead of the first antenna. At this time, the current distribution on each antenna branch is as follows: Figure 8 shown.
[0100] In the example of Table 1, when in the RX1 and RX2 combined switch state, the third antenna can be used as another satellite communication receiving antenna, operating at the satellite communication receiving frequency. At this time, the third antenna and the first antenna are both connected to a communication chip such as a modem with dual receiving channels.
[0101] In an embodiment of the present application, when the first antenna is operating, the third antenna can also function independently as a parasitic antenna for the first antenna, without requiring the third antenna to function together with the second antenna as a parasitic antenna for the first antenna. In this case, the second antenna is not operating, but its resonant frequency does not need to be tuned to near the first frequency. This implementation method has requirements for the distance from the third antenna to the first antenna. The length of the signal conduction path between the first antenna and the third antenna is less than a specific threshold. Specifically, the length of the conduction path from one end of the third antenna near the slot 26 to one end of the first antenna near the slot 25 is less than a specific threshold, such as 42 mm. This conduction path extends along the frame.
[0102] Figure 19 An example of antenna related parameters is shown in Figure 19 In this example, the corner frame is arc-shaped, and its conductive path length can be approximately represented by its horizontal length x2 and vertical length y1. The length x1 of the radiator 20A of the first antenna can be approximately 29.4 mm, the width of the gap 25 (Gap1) can be approximately 0.8 mm, and the width of the gap 26 (Gap2) can be approximately 1.1 mm. The horizontal length x2 of the radiator 21A of the second antenna can be approximately 10 mm, and the vertical length y1 of the radiator 21A of the second antenna can be approximately 13.7 mm. The length of the radiator 22A of the third antenna can be 14.5 mm, that is, Figure 19 In y2. Figure 19 As shown, the radiator 22A of the third antenna can be even longer, and further includes a side frame section with a length of 14.8 mm on the other side of Gap3. The width of Gap3 can be approximately 1 mm to 1.45 mm.
[0103] In the embodiment of this application, Figure 20 As shown, a matching circuit connecting the second antenna 18 and the third antenna 19 can also be provided at the slot 26. This matching circuit is configured to pass signal currents of the first frequency while blocking signal currents of the second frequency. This ensures that only currents near the first frequency are excited in the third antenna when the third and second antennas function as parasitic antennas for the first antenna, thereby improving the coverage of the radiation pattern.
[0104] Furthermore, to avoid the impact of hand-holding, the first antenna, second antenna, and third antenna can all be arranged in the upper half of the electronic device. Moreover, since the motherboard is generally stacked on the upper part of the device, their placement in the upper half of the device can also shorten the coaxial cable feeding the antenna and reduce path loss. Here, the upper half refers to the part of the device closer to the top frame, relative to the lower half closer to the bottom frame, and generally refers to the part of the device above the line connecting the midpoints of the two side frames.
[0105] In the design of the whole machine antenna, such as Figure 4AAs shown, a slit 27 may be further 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 may also be provided at the top frame 13A, and the fourth antenna may include a radiator 23A and a feeding point 23B provided on the radiator 23A. The fourth antenna may be implemented as a multiplexing antenna for 5G Wi-Fi and N78. In practical applications, the operating frequency of the fourth antenna may be adjusted to the 5G Wi-Fi or N78 frequency band by connecting a tuning switch to the fourth antenna. Not limited to the multiplexing antenna for 5G Wi-Fi and N78, the fourth antenna may also be implemented as other types of antennas, such as a satellite navigation positioning antenna, etc., which is not limited in the embodiments of the present application.
[0106] In addition, an embodiment of the present application further provides a directional pattern control method, which can be applied to the electronic device 10 provided in an embodiment of the present application.
[0107] Figure 21 The overall process of the directional pattern control method provided by the embodiment of the present application is shown below.
[0108] S51. The electronic device may start satellite communication and control the second tuning switch to be in the first switch state.
[0109] S52. When a change in the posture of the electronic device is detected during satellite communication, the electronic device may control the second tuning switch to be in a second switch combination state when the first beam is directed toward the satellite. The first beam may be a beam of a satellite communication signal when the second tuning switch is in the second switch state.
[0110] When satellite communication is initially initiated, the electronic device sets the second tuning switch to the first state, allowing the second antenna to function as a parasitic antenna for the first antenna. This improves the first antenna's coverage pattern and creates a wide-beam satellite communication antenna, facilitating satellite alignment. When the user adjusts the electronic device's position for alignment and finds the first beam pointing toward the satellite, the second tuning switch is set to the second state. This stops the second antenna from functioning as a parasitic antenna for the first antenna, narrowing the first antenna's beam and increasing antenna gain, improving satellite call quality.
[0111] The first beam is the beam of the first antenna when the second antenna is not used as a parasitic antenna of the first antenna, and 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, and the beam angle of the first beam. Specifically, the electronic device can determine whether the first beam is pointing to the satellite based on the relative position of the electronic device and the satellite, and the beam angle of the first beam. The relative position of the electronic device and the satellite can be determined based on satellite ephemeris data, and the beam angle of the first beam can be determined based on the position of the electronic device on the earth, the posture of the electronic device, and the directional pattern of the first beam. The position of the electronic device on the earth can be detected by devices such as a compass and a global positioning system (GPS).
[0112] On the screen, the electronic device can display the satellite communication situation. Figure 24 As shown in FIG. 6 , a satellite marker 61 indicates the direction of the satellite, and a sector-shaped area 62 indicates the beam coverage direction of the first antenna. When the satellite marker 61 falls within the sector-shaped area 62, it indicates that the satellite is successfully aligned; when the satellite marker 61 does not fall within the sector-shaped area 62, it indicates that the alignment is not successful.
[0113] Furthermore, when satellite communications are initiated, the electronic device can control the third tuning switch to a third switching state. This allows the third antenna to function as a parasitic antenna for the first antenna at the start of satellite communications, further improving the first antenna's coverage pattern and forming a wider beam. When a change in the electronic device's attitude is detected during satellite communications, if the first beam is pointing toward the satellite, the electronic device can control the third tuning switch to a fourth switching state while the second tuning switch is in the second switching state. This prevents the second and third antennas from functioning as parasitic antennas for the first antenna, narrowing the first antenna's beam and increasing antenna gain, thereby improving satellite call quality.
[0114] Satellite communication can include signal transmission and signal reception. During the signal transmission phase (uplink phase) of satellite communication, the electronic device can control a first tuning switch to tune the resonant frequency of the first antenna to the first antenna's transmission frequency; during the signal reception phase (downlink phase) of satellite communication, the electronic device can control the first tuning switch to tune the resonant frequency of the first antenna to the first antenna's reception frequency.
[0115] Furthermore, before determining whether the first beam is pointing toward a satellite, the electronic device can also determine that the second beam is pointing toward a satellite. The second beam is the satellite communication beam when the second tuning switch is in the first switch combination. In this way, after determining that the wide beam (second beam) is pointing toward a satellite, the electronic device can consider whether to switch to the narrow beam (first beam), thus saving processing time.
[0116] like Figure 22 As shown, in addition to the antenna described in the above embodiment, the electronic device provided in the embodiment of the present application may further 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, an earphone jack 170D, a sensor module 180, a button 190, a motor 191, an indicator 192, a camera 193, and the like. Among them, the sensor module 180 may include a gyroscope sensor 180B, an acceleration sensor 180E, and a touch sensor 180K. The various components in the electronic device 300 may be connected via a bus.
[0117] Among them, the processor 110 is responsible for providing computing power and can be used as the computing module of the electronic device 300. The display 130, audio module 170, speaker 170A, receiver 170B, microphone 170C, headphone jack 170D, sensor module 180, button 190, motor 191, indicator 192, camera 193 and other input and output components are responsible for providing 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 an integrated circuit of a system on chip (SOC). SOC is a system-on-chip.
[0118] The processor 110 may include an application processor (AP), a baseband processor chip (BP), etc., wherein the AP may be responsible for running the operating system, user interface, and application programs on the electronic device 300; the BP may be responsible for sending and receiving wireless signals and managing radio frequency services.
[0119] The memory 120 may include a program storage area and a user data storage area. The program storage area may store an operating system and one or more application programs, and the data storage area may store data created by a user while using the electronic device 300. The memory 120 may be a high-speed random access memory or a non-volatile memory, such as a disk, flash memory, or universal flash storage (UFS). The memory 120 may also be an external memory card, such as a Micro SD card.
[0120] The memory 120 may also store a computer program of the image editing method provided in the embodiment of the present application. When the processor 110 reads the computer program from the memory 120 and runs the computer program, the electronic device 300 can execute the directional pattern control method provided in the embodiment of the present application.
[0121] The 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 be composed of a filter, a switching circuit, a power amplifier, a modem, etc. The modem can be used to modulate the low-frequency baseband signal to be transmitted into a medium- and 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 being processed by the baseband processor, the low-frequency baseband signal is passed to the application processor. The application processor outputs a sound signal through the audio module and / or displays an image or video through the display.
[0122] 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 technology (IR) and other wireless communication modules and their respective antennas.
[0123] Figure 22 The illustrated structure does not constitute a specific limitation on the electronic device. The electronic device may include more or fewer components than shown, or may combine or separate some components, or arrange the components differently. The various components shown in the illustrations may be implemented in hardware, software, or a combination of software and hardware.
[0124] At the software system level of the electronic device, a specific implementation of the directional pattern control method provided in the embodiment of the present application can be as follows: Figure 23 shown. Figure 23 In the example, "sate ll ite_service" indicates a satellite communication application or service, which can start or stop satellite communication according to user operation and can also display Figure 24The user interface shown in the figure; "ri l_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 directional pattern control method executed by the electronic device can be completed by the interaction of these modules.
[0125] S61. In response to the user initiating a satellite call, the electronic device may begin parsing the configuration file to determine a switch combination state at the beginning of the satellite communication. The switch combination state may be a switch combination state of the first tuning switch and the second tuning switch, or a switch combination state of the first tuning switch, the second tuning switch, and the third tuning switch.
[0126] For example, the electronic device may parse a configuration file through a satellite communication application to determine a switch combination state at the beginning of satellite communication. The switch combination state may be a switch combination state of the first tuning switch and the second tuning switch, or a switch combination state of the first tuning switch, the second tuning switch, and the third tuning switch.
[0127] The configuration file can be used to record all switch combination states of the first tuning switch, the second tuning switch, and the third tuning switch when the first antenna transmits a signal, and all switch combination states of the first tuning switch, the second tuning switch, and the third tuning switch when the first antenna receives a signal. The configuration file can be, for example, as shown in Table 1 above.
[0128] As to which switch combination state in the configuration file the switch combination state at the beginning of satellite communication is, this can be recorded in the first parameter. For example, the first parameter can be the parameter satantstatese l.
[0129] S62. The electronic device may 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 period.
[0130] Exemplarily, the electronic device may transmit the first parameter and the second parameter to the first module via a satellite communication application.
[0131] Exemplarily, the first module may be a ri l_adapter_ext module, and the second parameter may be a parameter satantrpt.
[0132] S63-S64. The electronic device may set the initial switch state of the tuning switch of each antenna based on 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 enabling the first antenna to have a wide beam. The modem may report the antenna status of the satellite communication antenna to the satellite communication application via antenna status reporting.
[0133] For example, after receiving the first and second parameters, the electronic device can control the modem via the first module to set the initial switch state of the tuning switches of each antenna and control the modem to enable antenna status reporting. In response to the control action of the first module, the modem sets the initial switch state of the tuning switches of each antenna.
[0134] S65. The electronic device can detect a change in the posture of the electronic device and decide whether to switch the switch combination state.
[0135] For example, the electronic device can detect a change in the posture of the electronic device through a satellite communication application and decide whether to switch the switch combination state.
[0136] Specifically, the electronic device can determine whether the first beam is pointing toward the satellite based on the relative position of the electronic device and the satellite and the beam angle of the first beam, and decide to switch the switch combination state if the first beam is pointing toward the satellite. Here, switching can include switching the second tuning switch to the second switch state, or switching the switch states of the second tuning switch and the third tuning switch to the second switch state and the third switch state, respectively.
[0137] S66. When the switch combination state needs to be switched, the electronic device may update the first parameter.
[0138] Exemplarily, the electronic device may transmit the updated first parameter to the first module via a satellite communication application.
[0139] S67-S68. The electronic device may change the switch combination state according to the updated first parameter.
[0140] For example, the electronic device can control the modem to change the switch combination state based on the updated first parameter through the first module. The modem can switch the switch combination state based on 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 directivity pattern of the first antenna and improving the signal gain of the first antenna.
[0141] S69. In response to the user turning off the satellite call, the electronic device may update the second parameter, where the updated second parameter is used to indicate turning off the antenna status reporting.
[0142] Exemplarily, the electronic device may transmit the updated second parameter to the first module via a satellite communication application.
[0143] S70. The electronic device may turn off antenna status reporting.
[0144] Illustratively, the electronic device may control the modem to turn off antenna status reporting through the first module.
