[0001] This application claims priority to Chinese Patent Application No. 202410571737.2, filed with the State Intellectual Property Office of China on May 7, 2024, entitled "A Folding Terminal Device", 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 an antenna device and electronic equipment. Background Technology

[0003] With the continuous development of communication technology, electronic devices are trending towards miniaturization, thinner designs, and higher screen-to-body ratios. Furthermore, as the integration requirements of electronic devices increase, the number of internal components grows, leading to a shrinking internal architectural space. This further compresses the available space for antennas, impacting their performance. On top of this, the increasing demand from users for diverse communication functions makes it increasingly difficult to achieve such functionality within a limited architectural space. Summary of the Invention

[0004] This application provides an antenna device and an electronic device for achieving diverse communication functions within a limited architectural space.

[0005] To achieve the above objectives, this application adopts the following technical solution:

[0006] One aspect of this application provides an antenna device including a ground plane, an antenna structure, a communication chip, a first power amplifier, a second power amplifier, and a first gating switch. The antenna device has a clearance area between the ground plane and the antenna structure, wherein the antenna structure includes a first satellite communication antenna and a first ground network communication antenna. The first satellite communication antenna includes a first stub with a first electrical connection terminal. The first ground network communication antenna includes a first stub. The communication chip has a first satellite transmitting end and a first ground network transmitting end. The first satellite transmitting end is used to transmit radio frequency signals in a first satellite operating frequency band, and the first ground network transmitting end is used to transmit radio frequency signals in a first ground network operating frequency band. The first power amplifier is coupled to the first satellite transmitting end, and the second power amplifier is coupled to the first ground network transmitting end. The first power amplifier and the second power amplifier have different efficiencies. The first gating switch is coupled between the first power amplifier and the first electrical connection terminal. The first gating switch is also coupled between the second power amplifier and the first electrical connection terminal. The first gating switch is located in the clearance area. The first gating switch is used to connect either the first satellite transmitting end or the first ground network transmitting end to the first electrical connection terminal.

[0007] In summary, the antenna device provided in this application includes an antenna structure in which the communication chip can have different signal transmitting ends, such as a first satellite transmitting end and a first ground network transmitting end. In this case, the communication chip can transmit radio frequency signals in the first satellite operating frequency band via the first satellite transmitting end, and also transmit radio frequency signals in the first ground network operating frequency band via the first ground network transmitting end. This allows the communication chip to transmit radio frequency signals in two different operating frequency bands. Therefore, it eliminates the need for two separate chips for transmitting the aforementioned different operating frequency bands, allowing the communication chip to have a smaller size compared to the two separate chips, thus improving the space utilization of the antenna device. Furthermore, to meet the system energy consumption requirements, the power amplification efficiencies required for the radio frequency signals transmitted by the different signal transmitting ends of the communication chip, such as the first satellite transmitting end and the first ground network transmitting end, can be different. In this case, compared with the scheme where the first satellite transmitter and the first ground network transmitter share the same power amplifier, in this embodiment of the application, the first satellite transmitter and the first ground network transmitter can be connected to a first power amplifier and a second power amplifier with different efficiencies, so that both the first power amplifier and the second power amplifier can work at their highest efficiency, thereby reducing the input power of the first power amplifier and the second power amplifier respectively, so as to meet the requirements of system energy loss.

[0008] Furthermore, to further improve the space utilization of the antenna device, both the first satellite communication antenna and the first ground network communication antenna include the same stub, namely the first stub. This first stub has a first electrical connection terminal. To enable one of the antennas sharing the stub—the first satellite communication antenna and the first ground network communication antenna—to operate independently at any given time, the communication chip can send a control signal to the first gating switch to connect the first satellite transmitter to the first electrical connection terminal. Therefore, the first satellite transmitter, the first power amplifier, the first gating switch, and the first electrical connection terminal can form a communication link for the data to be transmitted by the first satellite communication antenna, allowing the radio frequency signal of the first satellite operating frequency band transmitted by the first satellite transmitter to be transmitted to the first electrical connection terminal to power the first stub, thereby enabling the first stub to function as the first satellite communication antenna to transmit the aforementioned radio frequency signal of the first satellite operating frequency band. Alternatively, the communication chip can send a control signal to the first gating switch to connect the first ground network transmitter to the first electrical connection terminal. Therefore, the first ground network transmitter, the second power amplifier, the first gating switch, and the first electrical connection can form a communication link for the data to be transmitted by the first ground network communication antenna, so that the radio frequency signal of the first ground network operating frequency band transmitted by the first ground network transmitter is transmitted to the first electrical connection to power the first stub, thereby enabling the first stub to act as the first ground network communication antenna to transmit the radio frequency signal of the first ground network operating frequency band.

[0009] Based on this, the first satellite communication antenna and the first ground network communication antenna can share the same stub (i.e., the first stub), and the feed terminals are both the first electrical connection terminals of the first stub. This eliminates the need for separate stubs and feed terminals for the first satellite communication antenna and the first ground network communication antenna, thereby simplifying the number of stubs and feed terminals in the antenna device, saving internal space in electronic equipment with the wiring device, and improving the space utilization of the antenna device. This allows for diversified communication functions within a limited architectural space. Therefore, the antenna device provided in this application embodiment can improve the space utilization of the antenna device while meeting system energy loss requirements. Furthermore, the first gating switch located within the clearance area has different conduction states, ensuring that the first satellite communication antenna or the first ground network communication antenna is not simultaneously in operation. For example, when the first gating switch connects the first satellite transmitter to the first electrical connection terminal, the first satellite communication antenna is in operation. At this time, the first ground network communication antenna is in a non-operational state. Similarly, when the first gating switch connects the first ground network transmitter to the first electrical connection terminal, the first ground network communication antenna is in operation. At this time, the first satellite communication antenna is in a non-operational state. This reduces the probability of mutual interference between the communication links of the first ground network communication antenna and the communication links of the first ground network communication antenna, thereby reducing signal loss.

[0010] In one optional embodiment, the communication chip further includes a first satellite first receiver, which is used to receive radio frequency signals in the operating frequency band of the first satellite. The antenna device further includes a first radio frequency switch, which is coupled between the first satellite transmitter and a first gating switch, and is also coupled between the first satellite first receiver and the first gating switch. The first radio frequency switch is used to connect the first satellite transmitter or the first satellite first receiver to the first gating switch. In this way, the communication chip can send a control signal to the first radio frequency switch to control the first radio frequency switch to connect the first satellite transmitter to the first gating switch, so that the communication link of the data to be transmitted by the first satellite communication antenna is connected to the first gating switch. Based on this, when the communication chip sends a control signal to the first gating switch to control the first gating switch to connect the first radio frequency switch to the first electrical connection terminal, the radio frequency signals in the operating frequency band of the first satellite transmitted by the communication chip through the first satellite transmitter can be transmitted to the first electrical connection terminal through the aforementioned communication link of the data to be transmitted, so as to power the first stub, so that the first stub can act as the first satellite communication antenna to transmit the aforementioned radio frequency signals in the operating frequency band of the first satellite. Alternatively, the communication chip sends a control signal to the first RF switch to connect the first satellite's first receiving end to the first gating switch, thereby connecting the communication link for the data to be received by the first satellite communication antenna to the first gating switch. Based on this, when the communication chip sends a control signal to the first gating switch to connect the first RF switch to the first electrical connection terminal, the first stub can serve as at least a part of the first satellite communication antenna to receive RF signals in the first satellite's operating frequency band and transmit them to the first satellite's first receiving end via the aforementioned communication link for data processing by the communication chip. Furthermore, when the first gating switch selects the first stub as at least a part of the first ground network communication antenna for signal transmission and reception, the aforementioned RF switch is not required in the signal path between the first stub and the first ground network transmitting end, thus reducing signal loss in this path. Moreover, the performance indicators of the first gating switch located in the clearance area can include voltage and current. Therefore, by adjusting the voltage or current across the first gating switch, the signal loss can be further reduced.

[0011] In one optional embodiment, the antenna device further includes a first RF test socket and a second RF test socket. The first RF test socket is coupled between a first selector switch and a first satellite transmitter. The first RF test socket can be connected to test instruments to test and adjust relevant parameters of the impedance matching of the communication link of the first satellite communication antenna. The second RF test socket is coupled between the first selector switch and a first ground network transmitter. The second RF test socket can be connected to test instruments to test and adjust relevant parameters of the impedance matching of the communication link of the first ground network communication antenna.

[0012] In one optional embodiment, the antenna device further includes a first impedance matching network. The first impedance matching network is coupled to at least one of a first or second RF test socket and a first selector switch; alternatively, a first portion of the first impedance matching network is coupled to at least one of the first or second RF test sockets and the first selector switch, and a second portion of the first impedance matching network is coupled to the first selector switch and a first electrical connection terminal. The first impedance matching network can perform impedance matching on the communication link of at least one of the first satellite communication antenna or the first ground network communication antenna. In this way, when the first selector switch is activated by the first electrical connection terminal and the first RF switch, the first selector switch disconnects the first electrical connection terminal and the first ground network transmitter terminal, thereby preventing signals from the first ground network transmitter terminal from affecting the communication link of the first satellite communication antenna. This ensures that the impedance matching effect of the communication link of the first satellite communication antenna matches the structure and related parameters of the first impedance matching network, achieving the goal of increasing the radiated power of the first satellite communication antenna and reducing signal loss. Alternatively, when the first gating switch is turned on to connect the first electrical connection terminal and the first ground network transmitter terminal, the first gating switch will disconnect the first electrical connection terminal and the first satellite transmitter terminal, so that the signal from the first satellite transmitter terminal will not affect the communication link of the first ground network communication antenna. This will allow the impedance matching effect of the communication link of the first ground network communication antenna to match the structure and related parameters of the first impedance matching network, thereby increasing the radiation power of the first ground network communication antenna and reducing signal loss.

[0013] In an optional embodiment, the antenna device further includes a first impedance matching network coupled between the first gating switch and the first electrical connection terminal. The technical effects of this first impedance matching network are the same as described above, and will not be repeated here.

[0014] In one optional embodiment, the first satellite communication antenna further includes a second stub, spaced apart from the first stub. The second stub has a second electrical connection terminal. The communication chip also has a first satellite second receiver terminal. The first satellite second receiver terminal is used to receive radio frequency signals in the operating frequency band of the first satellite. The first satellite second receiver terminal is coupled to the second electrical connection terminal. In this case, when the first satellite communication antenna transmits the aforementioned radio frequency signals in the operating frequency band of the first satellite, the first stub is in an active state to transmit the radio frequency signals in the operating frequency band of the first satellite. When the first satellite communication antenna receives the radio frequency signals in the operating frequency band of the first satellite, the first stub and the second stub can be in an active state simultaneously to receive the radio frequency signals in the operating frequency band of the first satellite. In this way, the receiving beamwidth and gain of the first satellite communication antenna can be expanded, thereby making it easier for electronic devices to implement satellite tracking functions.

[0015] In one optional embodiment, the antenna structure further includes a second satellite communication antenna, which includes a second stub. The communication chip has a second satellite transmitting end and a second satellite first receiving end. The second satellite transmitting end is used to transmit radio frequency signals in the operating frequency band of the second satellite, and the second satellite first receiving end is used to receive radio frequency signals in the operating frequency band of the second satellite. Furthermore, the antenna device also includes a second radio frequency switch, which is coupled between the first satellite second receiving end and a second electrical connection end. The second radio frequency switch is also coupled between the second satellite transmitting end and the second electrical connection end. The second radio frequency switch is used to turn on the first satellite second receiving end, the second satellite transmitting end, or the second satellite first receiving end and the second electrical connection end. For example, the first satellite communication antenna can be a high-orbit satellite antenna, and the second satellite communication antenna can be a low-orbit satellite antenna. Therefore, the electronic device can integrate two satellite communication antennas within a limited space, allowing the user to select between the two satellites as needed or based on the user's location, thereby achieving diversified communication functions.

[0016] In one optional embodiment, the antenna device further includes a second gating switch, a third RF test socket, and a second impedance matching network. The second gating switch is coupled between a second RF switch and a second electrical connection terminal, and is located in a clearance area. The third RF test socket is coupled between the second gating switch and the second RF switch. At least a portion of the second impedance matching network may be coupled between the second gating switch and the second electrical connection terminal; or, at least a portion of the second impedance matching network may be coupled to the side of the second gating switch away from the second electrical connection terminal, for example, the second impedance matching network may be coupled between the second gating switch and the third RF test socket. Alternatively, for example, a first portion of the second impedance matching network may be coupled between the second gating switch and the second electrical connection terminal, and a second portion of the second impedance matching network may be coupled between the second gating switch and the third RF test socket. Wherein, when the first gating switch connects the first ground network transmitter to the first electrical connection terminal, the second gating switch is used to disconnect at least a portion of the second impedance matching network from the second electrical connection terminal. The second impedance matching network can perform impedance matching on the communication link of the second satellite communication antenna. The third RF test socket can be connected to test instruments to test and adjust the impedance matching parameters of the communication link of the second satellite communication antenna. Based on this, when the electronic device is in a folded state, and the first ground network communication antenna is transmitting or receiving RF signals in the first ground network operating frequency band, in order to avoid the second impedance matching network affecting the signal on the second stub, which is a parasitic antenna of the first ground network communication antenna, the second gating switch can disconnect at least a portion of the second impedance matching network from the second electrical connection terminal of the second stub, thereby achieving the purpose of increasing the aperture and gain of the first ground network communication antenna.

[0017] In one optional embodiment, the first electrical connection terminal is located at the end of the first stub facing away from the second stub. The second electrical connection terminal is located at the end of the second stub facing away from the first stub. In this case, the first electrical connection terminal of the first stub can be located at the end of the first stub facing away from the second stub, thereby allowing the first electrical connection terminal to be located at the open end of the first stub, which is beneficial for increasing the antenna aperture. Similarly, the second electrical connection terminal can be located at the end of the second stub facing away from the first stub, thereby allowing the second electrical connection terminal to be located at the open end of the second stub, which also increases the antenna aperture.

[0018] In one optional embodiment, the second satellite communication antenna further includes a third stub, spaced apart from the first and second stubs, and the third stub has a third electrical connection terminal. The communication chip also has a second satellite receiver terminal for receiving radio frequency (RF) signals in the second satellite's operating frequency band, and the second satellite receiver terminal is coupled to the third electrical connection terminal. In this case, when the second satellite communication antenna transmits the aforementioned RF signals in the second satellite's operating frequency band, the second stub is in an active state to transmit the RF signals in the second satellite's operating frequency band. When the second satellite communication antenna receives the RF signals in the second satellite's operating frequency band, the second and third stubs are simultaneously in an active state to receive the RF signals in the second satellite's operating frequency band. This expands the receiving beamwidth and gain of the second satellite communication antenna, making it easier for electronic devices to implement satellite targeting functionality.

[0019] In one optional embodiment, the second satellite communication antenna further includes a first stub. The communication chip also has a second satellite receiver for receiving radio frequency (RF) signals in the second satellite's operating frequency band. The second satellite receiver is coupled to a first electrical connection terminal. Similarly, when the second satellite communication antenna transmits RF signals in the second satellite's operating frequency band, the second stub is in an active state to transmit RF signals in the second satellite's operating frequency band. When the second satellite communication antenna receives RF signals in the second satellite's operating frequency band, both the second stub and the first stub are simultaneously active to receive RF signals in the second satellite's operating frequency band. This expands the receiving beamwidth and gain of the second satellite communication antenna, making it easier for electronic devices to implement satellite tracking functionality.

[0020] In one optional embodiment, the antenna structure further includes a third satellite communication antenna, which includes a fourth stub spaced apart from the first stub and has a fourth electrical connection terminal. The communication chip also includes a third satellite transmitter and a third satellite receiver; the third satellite transmitter transmits radio frequency signals in the third satellite's operating frequency band, and the third satellite receiver receives radio frequency signals in the third satellite's operating frequency band. The antenna device also includes a third radio frequency switch coupled between the third satellite transmitter and the fourth electrical connection terminal; the third radio frequency switch is also coupled between the third satellite receiver and the fourth electrical connection terminal; the third radio frequency switch is used to connect the third satellite transmitter or the third satellite receiver to the fourth electrical connection terminal. For example, the aforementioned third satellite communication antenna can be a high-orbit satellite communication antenna, and this third satellite communication antenna can be used solely for short message transmission and reception; this third satellite communication antenna can also be called a satellite short message antenna. Based on this, an electronic device can integrate three satellite communication antennas within a limited space. Users can select between the two satellites as needed, or the electronic device can select based on the user's location, thereby achieving diversified communication functions.

[0021] In one optional embodiment, the antenna structure further includes a satellite positioning antenna, which includes a fourth segment. The communication chip also has a positioning satellite receiver for receiving radio frequency signals in the operating frequency band of the fourth satellite. A third radio frequency switch is also coupled between the positioning satellite receiver and the fourth electrical connection terminal. The third radio frequency switch is used to connect the third satellite transmitter, the third satellite receiver, or the positioning satellite receiver to the fourth electrical connection terminal. The satellite positioning antenna and the third satellite communication antenna can share the aforementioned fourth segment. Therefore, the electronic device can integrate three satellite communication antennas and one satellite positioning antenna within a limited space, enabling diversified communication functions.

[0022] In one optional embodiment, the antenna structure further includes a second ground network communication antenna, which includes a fourth stub. The communication chip also has a second ground network transmitter. The second ground network transmitter is used to transmit radio frequency signals in the second ground network operating frequency band. A third radio frequency switch is also coupled between the second ground network transmitter and the fourth electrical connection terminal. The third radio frequency switch is used to connect the third satellite transmitter, the third satellite receiver, or the second ground network transmitter to the fourth electrical connection terminal. The second ground network communication antenna and the third satellite communication antenna can share the aforementioned fourth stub; therefore, the electronic device can achieve diversified communication functions within a limited space.

[0023] In one optional embodiment, the antenna structure further includes a third ground network communication antenna, which includes a fifth stub spaced apart from the first stub and has a fifth electrical connection terminal. The communication chip also has a third ground network transmitter. The third ground network transmitter is used to transmit radio frequency signals in the third ground network operating frequency band. The third ground network transmitter is coupled to the fifth electrical connection terminal. For example, the second and third ground network communication antennas can be Wi-Fi antennas in different frequency bands, thereby enabling diversified communication functions.

[0024] In one optional embodiment, the communication chip includes a first satellite communication chip and a first ground network communication chip. The first satellite communication chip has a first satellite transmitting end. The first ground network communication chip has a first ground network transmitting end. For example, the first satellite communication chip and the first ground network communication chip can be separate packaged chips. Alternatively, for another example, the first satellite communication chip and the first ground network communication chip can be independent bare chips, packaged within the same chip package; this application does not limit this.

[0025] In one optional implementation, the first ground network communication chip is a cellular communication chip, and the first ground network operating frequency band is a cellular communication frequency band, thereby enabling the electronic device to have cellular communication functionality.

[0026] Another aspect of this application provides an antenna device. The antenna device may include an antenna structure and a communication chip. The antenna structure may include a first satellite communication antenna and a second satellite communication antenna. The first satellite communication antenna includes a first stub and a second stub. The first stub and the second stub are spaced apart, the first stub having a first electrical connection terminal and the second stub having a second electrical connection terminal. The second satellite communication antenna includes a second stub. The communication chip has a first satellite transmitting end, a first satellite first receiving end, a first satellite second receiving end, a second satellite transmitting end, and a second satellite first receiving end. The first satellite transmitting end and the first satellite first receiving end are coupled to the first electrical connection terminal. The first satellite second receiving end, the second satellite transmitting end, and the second satellite first receiving end are coupled to the second electrical connection terminal. The first satellite transmitting end is used to transmit radio frequency signals in the operating frequency band of the first satellite, and the first satellite first receiving end and the first satellite second receiving end are used to receive radio frequency signals in the operating frequency band of the first satellite. Based on this, the first satellite communication antenna has one transmitting end and two receiving ends, therefore the first satellite communication antenna can have a 1T2R function. Furthermore, the second satellite transmitter is used to transmit radio frequency signals in the second satellite's operating frequency band, and the second satellite receiver is used to receive radio frequency signals in the second satellite's operating frequency band. When either the first or second satellite communication antenna is in operation, the antenna in operation can perform at least one of satellite calls or satellite short message transmission and reception. For example, the first satellite communication antenna can be a high-orbit satellite antenna, and the second satellite communication antenna can be a low-orbit satellite antenna. Therefore, electronic devices can integrate two satellite communication antennas within a limited space. Users can select between the two satellites as needed, or the electronic device can select based on the user's location, thereby diversifying communication functions. When the first satellite communication antenna is operational and the second satellite communication antenna is inactive, the second segment of the second satellite communication antenna can be reused as a receiving antenna for the first satellite communication antenna, thus enabling the first satellite communication antenna to possess the aforementioned 1T2R function. Furthermore, when a user selects a satellite communication antenna with 1T2R functionality, such as the aforementioned first satellite communication antenna, for satellite calls, the receiving beamwidth and gain of the satellite communication antenna can be expanded, improving the sensitivity of the satellite communication antenna as a receiving antenna.

[0027] In one optional embodiment, the antenna structure further includes a first ground network communication antenna, which includes a first stub.

Both the second and third stubs can serve as receiving antennas for the second satellite communication antenna, which can expand the width and gain of the receiving beam of the second satellite communication antenna, thereby making it easier for electronic devices to achieve satellite targeting functionality.

[0030] In one optional embodiment, the second satellite communication antenna further includes a first stub. The communication chip also has a second satellite second receiver for receiving radio frequency signals in the operating frequency band of the second satellite. The second satellite second receiver is coupled to a first electrical connection terminal. Both the second stub and the first stub can serve as receiving antennas for the second satellite communication antenna, which can expand the width and gain of the receiving beam of the second satellite communication antenna, thereby making it easier for electronic devices to achieve satellite alignment functionality.

[0031] In an optional embodiment, the antenna structure further includes a third satellite communication antenna, which includes a fourth stub spaced apart from the first stub and has a fourth electrical connection terminal.

The antenna device also includes a third radio frequency switch, coupled between the third satellite transmitter and the fourth electrical connection terminal; the third radio frequency switch is also coupled between the third satellite receiver and the fourth electrical connection terminal, and the third radio frequency switch is used to connect either the third satellite transmitter or the third satellite receiver to the fourth electrical connection terminal. The technical effects of the third satellite communication antenna are the same as described above and will not be repeated here.

[0032] In another aspect, this application provides an antenna device comprising an antenna structure and a communication chip. The antenna structure includes a first satellite communication antenna and a satellite short message antenna. The first satellite communication antenna is used to realize at least one of satellite calls or satellite short message transmission and reception. The satellite short message antenna can be the aforementioned third satellite communication antenna. The first satellite communication antenna includes a first stub and a second stub. The first stub and the second stub are spaced apart, the first stub having a first electrical connection terminal and the second stub having a second electrical connection terminal. The satellite short message antenna includes a fourth stub, the fourth stub being spaced apart from the first stub and the second stub, the fourth stub having a fourth electrical connection terminal. The communication chip has a first satellite transmitter, a first satellite receiver, a second satellite receiver, a third satellite transmitter, and a third satellite receiver. The first satellite transmitter and the first satellite receiver are coupled to the first electrical connection terminal, the second satellite receiver is coupled to the second electrical connection terminal, and the third satellite transmitter or the third satellite receiver is coupled to the fourth electrical connection terminal.

For example, the first satellite communication antenna can be a high-orbit satellite antenna. Therefore, within a limited space, the electronic device can integrate two satellite communication antennas. Users can select between these two satellites as needed, or the electronic device can select based on the user's location, thus diversifying communication functions. For example, at any given time, only one of the first satellite communication antenna and the satellite short message antenna (i.e., the third satellite communication antenna) can be operational.

[0033] In another aspect, this application provides an electronic device including at least one metal frame and any of the antenna devices described above, wherein the metal frame includes an antenna structure within the antenna device. This electronic device has the same technical effects as the antenna devices provided in the foregoing embodiments, and will not be repeated here.

[0034] In one optional embodiment, the metal frame includes a top frame, a first side frame, a bottom frame, and a second side frame connected end to end. The top frame includes an antenna structure. When the user stands and holds the electronic device, the energy of the electromagnetic waves radiated by the antenna structure can be mainly concentrated on the side where the top frame is located, that is, the side of the electronic device facing the sky. This facilitates satellite operation of the electronic device, allowing the user to use satellite functions over a wider angular range and increasing the freedom of satellite function implementation.

[0035] In another aspect, this application provides an electronic device including a hinge, two metal frames, and an antenna device with a first satellite communication antenna and a second satellite communication antenna as described above.

The first satellite communication antenna includes the first and second segments. In this way, the radiation pattern of the first satellite communication antenna when transmitting the first satellite's operating frequency band is omnidirectional with the antenna pattern when receiving the first satellite's operating frequency band, achieving better circular polarization coverage and a larger coverage area. Furthermore, the radiation performance of the first satellite communication antenna is consistent when transmitting or receiving the first satellite's operating frequency band, thereby reducing the need for users to swing their phones to change the satellite alignment angle when using the first satellite communication antenna for satellite communication, making satellite alignment easier.

Detailed Implementation

[0074] The technical solutions of the embodiments of this application will be described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0075] In the following description, the terms "first," "second," etc., are used for descriptive convenience only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature. In the description of this application, unless otherwise stated, "a plurality of" means two or more.

[0076] Furthermore, in the embodiments of this application, directional terms such as "up," "down," "left," "right," "horizontal," and "vertical" may be defined relative to the orientation in which the components are schematically placed in the accompanying drawings. It should be understood that these directional terms can be relative concepts, used for relative description and clarification, and can change accordingly depending on the orientation in which the components are placed in the accompanying drawings.

[0077] The limitations mentioned in the embodiments of this application, such as symmetry (e.g., axial symmetry, or central symmetry), parallelism, perpendicularity, orthogonality, and similarity (e.g., same length, same width, etc.), are all relative to the current technological level, and not absolute and strict mathematical definitions. There can be a predetermined angular deviation between two mutually parallel or perpendicular components. In one embodiment, the predetermined angle can be an angle within the range of ±10°, for example, a predetermined angular deviation of ±5°.

[0078] In this application, unless otherwise expressly specified and limited, the term "connection" shall be interpreted broadly. For example, "connection" may be a fixed mechanical connection, a detachable mechanical connection, or an integral part; or, "connection" may be a direct connection or an indirect connection through an intermediate medium.

[0079] Furthermore, unless otherwise explicitly specified and limited, the term "coupling" should be interpreted broadly. For example, "coupling" can refer to a direct electrical connection, such as physical contact and electrical conduction between two components. It can also be understood as the electrical connection between different components in a circuit structure through physical lines that can transmit electrical signals, such as copper foil or wires on a printed circuit board (PCB), to transmit electrical signals. Alternatively, "coupling" can refer to an indirect electrical connection between two components through an intermediate medium. Or, "coupling" can refer to an electrical connection between two components in a non-contact manner, such as an electrical connection between two components using capacitive coupling to transmit electrical signals.

[0080] It should be noted that in the accompanying drawings of the embodiments of this application, components are represented by guide lines with arrows; parts are represented by guide lines only.

[0081] This application provides an electronic device that can be applied to various communication systems or protocols, such as Global System for Mobile Communication (GSM), Code Division Multiple Access (CDMA) systems, Wideband Code Division Multiple Access (WCDMA) systems, General Packet Radio Service (GPRS), and Long Term Evolution (LTE). This electronic device may have a display function and can include mobile phones, tablets, televisions, smart wearable products (e.g., smartwatches, smart bracelets), virtual reality (VR) electronic devices, augmented reality (AR) electronic devices, positioning devices, etc. This application does not impose any special limitations on the specific form of the above-mentioned electronic device.

[0082] In some embodiments of this application, the above-described electronic device may have a display function. For example, the electronic device 01 may be as follows: Figure 1 The illustrated candybar phone, electronic device 01, may include a housing 10 and a display screen 20 connected to the housing 10. For example, the display screen 20 may be a self-emissive display screen, such as an organic light-emitting diode (OLED) display screen, a micro (or mini) light-emitting diode (LED) display screen, or a quantum dot light-emitting diode (QLED) display screen, etc. Alternatively, for another example, the display screen 20 may also be a liquid crystal display (LCD) screen requiring a backlight.

[0083] For ease of description, an XYZ coordinate axis is established in the accompanying drawings. The XY surface formed by the X and Y directions can be parallel to the display surface (the surface used to display images) of the display screen 20. The Z direction can be perpendicular to the display surface of the display screen 20; that is, the Z direction can be the stacking direction of the housing 10 and the display screen 20. In some embodiments of this application, the housing 10 may include a metal frame 101 arranged around the display screen 20 and a base plate located on the back of the display screen 20. Figure 1 (Not shown in the image).

[0084] Alternatively, in other embodiments of this application, the aforementioned electronic device 01 may be as follows: Figure 2 The folding mechanism shown is illustrated. In this case, the electronic device 01 may include a display screen 20, a hinge 11, and two housings located on either side of the hinge, namely a first housing 10a and a second housing 10b. The type of display screen 20 is the same as described above and will not be repeated here. The display screen 20 can be connected to the first housing 10a and the second housing 10b. The first housing 10a and the second housing 10b can be rotatably connected via the hinge 11 to support and fold the display screen 20, thereby realizing the flattening and folding of the electronic device 01. In some embodiments of this application, the first housing 10a may include a first metal frame 101a disposed around a portion of the periphery of the display screen 20, and the second housing 10b may include a second metal frame 101b disposed around another portion of the periphery of the display screen 20.

[0085] In this folding machine, the X direction can be either the direction from the first housing 10a to the second housing 10b, or the direction from the second housing 10b to the first housing 10a. The Y direction can be parallel to the rotation axis of the first housing 10a and the second housing 10b.

[0086] The above example illustrates the case where electronic device 01 is a folding device, comprising two housings. In this case, electronic device 01 can be referred to as a two-fold folding device. This application does not limit the number of housings in electronic device 01; electronic device 01 can be a three-fold or more folding device. For ease of explanation, the following examples will use the aforementioned two-fold folding device as an example when electronic device 01 is a folding device.

[0087] Furthermore, the above examples are based on an electronic device having a display function. In other embodiments of this application, the electronic device may not have a display function, and this application does not limit this. For ease of explanation, the following examples are all based on an electronic device having a display function.

[0088] Based on this, in order to enable the aforementioned electronic device to have communication capabilities, the electronic device may include, for example... Figure 3The antenna device 30 shown may include an antenna structure 31, a communication chip 32, and a first selection switch S1. The antenna structure 31 may include multiple antennas, which are devices for receiving (Rx) or transmitting (Tx) electromagnetic wave radiation. In some cases, the term "antenna" is narrowly interpreted as a radiator that converts guided wave energy from a transmitter into radio waves, or converts radio waves into guided wave energy, for radiating and receiving radio waves. The modulated high-frequency current energy (or guided wave energy) generated by the transmitter is transmitted to the transmitting radiator via a feed line, where it is converted into electromagnetic wave energy of a certain polarization and radiated in the desired direction. The receiving radiator converts the electromagnetic wave energy of a certain polarization from a specific direction in space back into modulated high-frequency current energy, which is then transmitted to the receiver input via a feed line.

[0089] In some embodiments of this application, the following continues... Figure 3 As shown, the antenna structure 31 may include a first satellite communication antenna 311 and a first ground network communication antenna 312. The first satellite communication antenna 311 can be used to receive or transmit radio frequency signals in the operating frequency band of a first satellite. For example, the first satellite communication antenna 311 can be a high-orbit satellite communication antenna, for example, at an orbital altitude of approximately 35,786 kilometers. In this case, when the first satellite communication antenna 311 is used for voice calls, sending and receiving short messages (or short packets), or transmitting low-speed data, the aforementioned first satellite operating frequency band may include an uplink frequency band (e.g., 1980 MHz to 2010 MHz) and a downlink frequency band (e.g., 2170 MHz to 2200 MHz).

[0090] Alternatively, as another example, if the first satellite communication antenna 311 is the aforementioned high-orbit satellite communication antenna, it can also be used solely for sending and receiving short messages. In this case, the operating frequency band of the first satellite can include an uplink frequency band (e.g., 1610 MHz to 1626 MHz) and a downlink frequency band (e.g., 2483 MHz to 2500 MHz). Alternatively, as another example, the first satellite communication antenna 311 can also be a low-orbit satellite communication antenna, with an orbital altitude between 500 and 2000 kilometers, for example, 1175 kilometers. In this case, when the first satellite communication antenna 311 is used for voice calls, sending and receiving short messages, or transmitting low-speed data, the operating frequency band of the first satellite can include an uplink frequency band (e.g., 1668 MHz to 1675 MHz) and a downlink frequency band (e.g., 1518 MHz to 1525 MHz).

[0091] also, Figure 3The first ground network communication antenna 312 shown is used to receive or transmit radio frequency signals in the first ground network operating frequency band. For example, the first ground network communication antenna 312 can be a cellular antenna, and the first ground network operating frequency band can be a cellular communication frequency band. This cellular communication frequency band can include the middle high band (MHB), such as 1800 MHz-2700 MHz, and the 5G new radio (NR) band. Alternatively, for another example, the ground network communication antenna 312 can also be a wireless fidelity (WIFI) antenna, and the first ground network operating frequency band can be a WIFI communication frequency band, such as the WIFI 2.4G band (2400 MHz to 2483.5 MHz) or the WIFI 5G band (5150 MHz to 5825 MHz).

[0092] For ease of explanation, the following description uses the first satellite communication antenna 311 as a high-orbit antenna. The first satellite communication antenna 311 is used for voice calls, sending and receiving short messages (or short packets), or transmitting low-speed data. The first satellite operating frequency band may include an uplink frequency band (e.g., 1980 / MHz to 2010 / MHz) and a downlink frequency band (e.g., 2170 / MHz to 2200 / MHz). The first ground network communication antenna 312 can be a cellular antenna. The above-mentioned first ground network operating frequency band can be a cellular communication frequency band as an example for illustration.

[0093] In addition, continue as Figure 3 As shown, the first satellite communication antenna 311 may include a first stub 3001, which has a first electrical connection terminal 3101. The first ground network communication antenna 312 may include the aforementioned first stub 3001. Therefore, both the first satellite communication antenna 311 and the first ground network communication antenna 312 include the aforementioned first stub 3001, and thus the first satellite communication antenna 311 and the first ground network communication antenna 312 can share the first stub 3001.

[0094] On this basis, continue as Figure 3 As shown, the communication chip 32 may have a first satellite transmitter SAT1-Tx and a first ground network transmitter GN1-Tx. The first satellite transmitter SAT1-Tx can be used to transmit radio frequency signals in a first satellite operating frequency band (e.g., uplink band 1980 / MHz to 2010 / MHz). The first ground network transmitter GN1-Tx is used to transmit radio frequency signals in a first ground network operating frequency band (e.g., cellular communication band). For example, if the first ground network operating frequency band is a cellular communication band, the first ground network transmitter GN1-Tx can also be shared with the first ground network receiver GN1-Rx to transmit serial cellular transmit or receive signals.

[0095] For example, the communication chip 32 described above may include a baseband chip, or, in addition to a baseband chip, may include a portion of a radio frequency (RF) chip. The baseband chip can process digital signals, i.e., the low-frequency portion of the signal. For example, the baseband chip may include a digital signal processor (DSP), a modem, a codec, etc. The baseband chip can perform functions such as digital signal processing, modulation / demodulation, and channel encoding / decoding. Furthermore, the RF chip can process radio frequency signals, i.e., the high-frequency portion of the signal. The RF chip may include an RF amplifier, a mixer, a filter, a frequency synthesizer, etc. The RF chip is used to generate, amplify, modulate, and demodulate RF signals. A digital-to-analog converter (DAC) for converting digital signals to analog signals may be provided between the baseband chip and the RF chip.

[0096] In addition, continue as Figure 3 As shown, the first gating switch S1 is coupled between the first satellite transmitter SAT1-Tx and the first electrical connection terminal 3101. Furthermore, the first gating switch S1 is also coupled between the first ground network transmitter GN1-Tx and the first electrical connection terminal 3101. The first gating switch S1 can be used to connect either the first satellite transmitter SAT1-Tx or the first ground network transmitter GN1-Tx to the first electrical connection terminal 3101. For example, the first gating switch S1 can be a single-pole multi-throw (SPMT) switch, such as a single-pole four-throw (SP4T) switch. Alternatively, it can be a combination of multiple (e.g., four) single-pole single-throw (SPST) switches; this application does not limit this to any particular type.

[0097] In some embodiments of this application, the antenna device 30 may further include, for example: Figure 3 The diagram shows a first power amplifier (PA) 331 and a second power amplifier 332. The first power amplifier 331 is coupled to the first satellite transmitter SAT1-Tx, and the aforementioned first gating switch S1 is coupled between the first power amplifier 331 and the first electrical connection terminal 3101. In this configuration, the first satellite transmitter SAT1-Tx can be coupled to the first electrical connection terminal 3101 through the first power amplifier 331 and the first gating switch S1. The first power amplifier 331 can amplify the signal from the first satellite transmitter SAT1-Tx.

[0098] Furthermore, the second power amplifier 332 is coupled to the first ground network transmitter GN1-Tx, and the first gating switch S1 is also coupled between the second power amplifier 332 and the first electrical connection terminal 3101. In this case, the first ground network transmitter GN1-Tx can be coupled to the first electrical connection terminal 3101 through the second power amplifier 332 and the first gating switch S1. The second power amplifier 332 can amplify the signal from the first ground network transmitter GN1-Tx. For example, the first power amplifier 331 and the second power amplifier 332 can be part of the aforementioned radio frequency chip. Alternatively, for another example, the first power amplifier 331 and the second power amplifier 332 can be independent of the radio frequency chip, which is not limited in this application.

[0099] The first power amplifier 331 and the second power amplifier 332 mentioned above have different efficiencies. The efficiency of a power amplifier can be defined as the ratio of its output power to its input power, and it can be used to measure the energy conversion rate from power source to load. Higher efficiency means that while meeting the output power requirement, the input power is lower, i.e., the energy loss from power source to load is smaller; conversely, lower efficiency means greater energy loss.

[0100] For example, when the first satellite communication antenna 311 is a high-orbit antenna and the first satellite operating frequency band may include an uplink frequency band (e.g., 1980 MHz to 2010 MHz), and the first ground network communication antenna 312 is a cellular antenna and the aforementioned first ground network operating frequency band can be a cellular communication frequency band, the efficiency of the first power amplifier 331 can be greater than the efficiency of the second power amplifier 332. For example, the highest efficiency of the first power amplifier 331 can reach about 30 dB, and the highest efficiency of the second power amplifier 332 can reach about 28 dB.

[0101] In this way, by coupling the first satellite transmitter SAT1-Tx (used to transmit radio frequency signals in the operating frequency band of the first satellite) and the first ground network transmitter GN1-Tx (used to transmit in the operating frequency band of the first ground network) to a first power amplifier 331 and a second power amplifier 332 with different efficiencies, respectively, both the first power amplifier 331 and the second power amplifier 332 can operate at their highest efficiency. This allows for meeting the output power requirements of the first power amplifier 331 and the second power amplifier 332 while reducing their respective input power, thereby reducing energy loss. The above example illustrates this with the first power amplifier 331 having a higher efficiency than the second power amplifier 332. In other embodiments, the efficiency of the first power amplifier 331 may be lower than the efficiency of the second power amplifier 332.

[0102] Based on this, the aforementioned antenna device 30 has, for example, Figure 3 or Figure 4 The first selector switch S1 can be located within the clearance area 300 shown. The clearance area 300 can be the region containing the gap between the ground plane (GND) of the electronic device and the antenna structure 31. The following provides an example illustrating the configuration of the clearance area 300.

[0103] In some embodiments, the electronic device may include a printed circuit board (PCB), on which the first selection switch S1, the first power amplifier 331, the second power amplifier 332, and the communication chip 32 may be disposed and electrically connected. A metal layer in the PCB may serve as a ground plane (GND). The ground plane (GND) may be, for example, Figure 3 The rectangle shown, or the floor GND, can also be a shape with a hollow structure, for example... Figure 4 The L-shaped or U-shaped or other shapes shown. The cutout portion of the ground plane GND can be filled by the dielectric layer in the circuit board, so that the location of the dielectric layer can support the first selector switch S1.

[0104] In summary, the antenna device 30 provided in this application embodiment includes, as follows: Figure 3 The antenna structure 31 shown can have a communication chip 32 with different signal transmitting ends, such as a first satellite transmitter SAT1-Tx and a first ground network transmitter GN1-Tx. In this case, the communication chip 32 can transmit radio frequency signals of the first satellite operating frequency band (e.g., uplink band 1980 / MHz to 2010 / MHz) through the first satellite transmitter SAT1-Tx, and also transmit radio frequency signals of the first ground network operating frequency band (e.g., cellular communication band) through the first ground network transmitter GN1-Tx. This allows the communication chip 32 to transmit radio frequency signals of two different operating frequency bands. Therefore, it eliminates the need for two separate chips for transmitting radio frequency signals of the different operating frequency bands, allowing the communication chip 32 to have a smaller size compared to the two separate chips, thus improving the space utilization of the antenna device 30.

[0105] On this basis, continue as Figure 3As shown, to meet the system's energy consumption requirements, the power amplification efficiencies required for the radio frequency signals emitted by different signal transmitting ends of the communication chip 32, such as the first satellite transmitter SAT1-Tx and the first ground network transmitter GN1-Tx, can differ. In this case, compared to the scheme where the first satellite transmitter SAT1-Tx and the first ground network transmitter GN1-Tx share the same power amplifier, in this embodiment, the first satellite transmitter SAT1-Tx and the first ground network transmitter GN1-Tx can be respectively connected to a first power amplifier 331 and a second power amplifier 332 with different efficiencies. This allows both the first power amplifier 331 and the second power amplifier 332 to operate at their highest efficiency, thereby meeting the output power requirements of the first power amplifier 331 and the second power amplifier 332 while reducing their respective input power, thus achieving the system's energy consumption requirements.

[0106] Furthermore, in order to further improve the space utilization of the antenna device 30, continue as follows Figure 3 As shown, both the first satellite communication antenna 311 and the first ground network communication antenna 312 include the same stub, namely the first stub 3001. The aforementioned first stub 3001 has a first electrical connection terminal 3101. In order to enable one of the antennas, the first satellite communication antenna 311 and the first ground network communication antenna 312, to operate independently at a time, the communication chip 32 can send a control signal to the first gating switch S1 to control the first gating switch S1 to connect the first satellite transmitter SAT1-Tx to the first electrical connection terminal 3101. Therefore, the first satellite transmitter SAT1-Tx, the first power amplifier 331, the first gating switch S1, and the first electrical connection terminal 3101 can form a communication link for the data to be transmitted by the first satellite communication antenna 311. This allows the radio frequency signal of the first satellite operating frequency band (e.g., uplink frequency band 1980 / MHz to 2010 / MHz) transmitted by the first satellite transmitter SAT1-Tx to be amplified by the first power amplifier 331 and then transmitted to the first electrical connection terminal 3101 to power the first stub 3001. This enables the first stub 3001 to function as the first satellite communication antenna 311 to transmit the aforementioned radio frequency signal of the first satellite operating frequency band.

[0107] Or, continue as Figure 3As shown, the communication chip 32 can send a control signal to the first gating switch S1 to control the first gating switch S1 to connect the first ground network transmitter GN1-Tx to the first electrical connection terminal 3101. Therefore, the first ground network transmitter GN1-Tx, the second power amplifier 332, the first gating switch S1, and the first electrical connection terminal 3101 can form a communication link for the data to be transmitted by the first ground network communication antenna 312. This allows the radio frequency signal of the first ground network operating frequency band (e.g., cellular communication frequency band) transmitted by the first ground network transmitter GN1-Tx to be amplified by the second power amplifier 332 and then transmitted to the first electrical connection terminal 3101 to power the first stub 3001, thereby enabling the first stub 3001 to act as the first ground network communication antenna 312 to transmit the aforementioned radio frequency signal of the first ground network operating frequency band.

[0108] Based on this, the first satellite communication antenna 311 and the first ground network communication antenna 312 can share the same stub (i.e., the first stub 3001), and the feed terminals are both the first electrical connection terminal 3101 of the first stub 3001. In this way, it is unnecessary to separately configure different stubs and different feed terminals for the first satellite communication antenna 311 and the first ground network communication antenna 312, thereby simplifying the number of stubs and feed terminals in the antenna device 30, saving internal space in the electronic device containing the antenna device 30, and improving the space utilization of the antenna device 30. This allows for diversified communication functions within a limited architectural space. As can be seen from the above, the antenna device 30 provided in this application embodiment can improve the space utilization of the antenna device 30 while meeting system energy loss requirements.

[0109] Furthermore, the first gating switch S1, located within the clearance zone 300, has different conduction states, ensuring that the first satellite communication antenna 311 or the first ground network communication antenna 312 is not simultaneously in an operational state (e.g., transmitting a signal). For example, when the first gating switch S1 connects the first power amplifier 331 to the first electrical connection terminal 3101, the first satellite communication antenna 311 is operational. At this time, the second power amplifier 332 is disconnected from the first electrical connection terminal 3101, and the first ground network communication antenna 312 is in a non-operational state. Similarly, when the first gating switch S1 connects the second power amplifier 332 to the first electrical connection terminal 3101, the first ground network communication antenna 312 is operational. At this time, the first satellite communication antenna 311 is in a non-operational state. This reduces the probability of mutual interference between the communication links of the data to be transmitted by the first ground network communication antenna 312 and the communication links of the data to be transmitted by the first ground network communication antenna 312, thereby reducing signal loss.

[0110] In some embodiments of this application, the "electrical connection terminal" can be a segment of a radiator on an antenna stub. The term "terminal" should not be narrowly interpreted as necessarily an endpoint or end physically disconnected from other antenna stubs; it can also be considered a point or segment on a continuous antenna stub. In one embodiment, the "terminal" can include a coupling region on the stub that couples to other conductive structures. For example, when the antenna stub serves as the main feed radiator, and the electrical connection terminal is coupled to the feed circuit, this electrical connection terminal can be called the feed terminal. Alternatively, when the antenna stub serves as a parasitic stub, and the antenna stub can be capacitively or inductively grounded, this electrical connection terminal can also be called the ground terminal.

[0111] In addition, continue as Figure 3 As shown, the antenna device 30 may further include a tuning switch assembly 40 coupled to the electrical connection terminal 3101. The tuning switch assembly 40 may include a tuning device and a switch coupled to the tuning device. The tuning device may include at least one of a capacitor and an inductor. By controlling the switch to select different tuning devices coupled to the electrical connection terminal 3101, the antenna aperture of the first branch 3001 can be adjusted as needed. This application embodiment does not limit the structure of the tuning switch assembly 40.

[0112] In this application, the capacitor can be understood as lumped capacitance and / or distributed capacitance. Lumped capacitance refers to a capacitive component, such as a capacitor element; distributed capacitance (or distributed capacitance) refers to the equivalent capacitance formed by two conductive components separated by a certain gap. The inductor can be understood as lumped inductance and / or distributed inductance. Lumped inductance refers to an inductive component, such as an inductor element; distributed inductance (or distributed inductance) refers to the equivalent inductance formed through a conductive component of a certain length, such as the equivalent inductance formed by a conductor due to bending or rotation.

[0113] like Figure 4 As shown, in some embodiments of this application, the communication chip 32 may include a first satellite communication chip 321 and a first ground network communication chip 322. The first satellite communication chip 321 may have the aforementioned first satellite transmitter SAT1-Tx, and the first ground network communication chip 322 may have the aforementioned first ground network transmitter GN1-Tx. For example, the first satellite communication chip 321 and the first ground network communication chip 322 may be independent packaged chips. Alternatively, for another example, the first satellite communication chip 321 and the first ground network communication chip 322 may be independent bare chips, packaged within the same chip package; this application does not limit this.

[0114] Therefore, in order to improve the space utilization of electronic devices, when electronic device 01 is as follows Figure 5 In the case of the candybar phone shown, the metal frame 101 in the housing of the electronic device 01 may include an antenna structure 31 (e.g., Figure 3 At least a portion of (as shown). For example, a portion of the metal frame 101 can be reused as a first branch 3001 in the antenna structure 31. In some embodiments of this application, continuing as Figure 5 As shown, the metal frame 101 may include a top frame 1011, a first side frame 1012, a bottom frame 1013, and a second side frame 1014 connected end to end. The top frame 1011 and bottom frame 1013 may be arranged opposite each other, as may the first side frame 1012 and second side frame 1014. The top frame 1011 and bottom frame 1013 may refer to the frame when the user is standing and... Figure 5 When the handheld electronic device 01 is shown, the top bezel 1011 is located at the top and can face the sky, while the bottom bezel 1013 is located at the bottom and faces the ground. Alternatively, when the electronic device 01 includes a camera 100, the camera 100 is usually located in the upper half of the electronic device 01, and the top bezel 1011 is positioned closer to the camera 100 than the bottom bezel 1013.

[0115] Based on this, as can be seen from the above, Figure 5 The antenna structure 31 shown includes a first satellite communication antenna 311 for transmitting and receiving radio frequency signals. Therefore, the top frame 1011 can include the first satellite communication antenna 311 in this antenna structure, that is, the top frame 1011 can include a first stub 3001. In this way, the first satellite communication antenna 311 is located at the top of the electronic device 01, when the user... Figure 5 When the handheld electronic device 01 is shown, the energy of the electromagnetic waves radiated by the first satellite communication antenna 311 can be mainly concentrated on the side where the top frame 1011 is located, that is, the energy is concentrated on the side of the electronic device 01 facing the sky, which is conducive to realizing the satellite operation of the electronic device 01, allowing the user to use satellite functions in a wider range of angles and improving the freedom of satellite function implementation.

[0116] Or, when electronic device 01 is Figure 6 In the folding device shown, at least one of the first metal frame 101a and the second metal frame 101b, for example, the first metal frame 101a may include an antenna structure 31 (such as...). Figure 3 At least a portion of (shown). For example, a portion of the first metal frame 101a can be reused as the first branch 3001 in the antenna structure 31. Similarly, the portion of the first metal frame 101a or the second metal frame 101b near the camera can be reused as the aforementioned first branch 3001.

[0117] Based on this, such as Figure 7As shown, the communication chip 32 may further include a first satellite first receiver SAT1-Rx1, which can be used to receive radio frequency signals from the first satellite's operating frequency band (e.g., downlink band 2170 / MHz to 2200 / MHz). Furthermore, the antenna device 30 may also include a first radio frequency switch RFS1, which is coupled between the first satellite transmitter SAT1-Tx and a first gating switch S1. For example, if the antenna device 30 includes a first power amplifier 331, the first radio frequency switch RFS1 may be coupled between the first power amplifier 331 and the first gating switch S1.

[0118] Furthermore, the first radio frequency switch RFS1 is also coupled between the first satellite first receiver SAT1-Rx1 and the first gating switch S1. For example, the antenna device 30 may also include a low noise amplifier (LNA), which can be coupled between the first satellite first receiver SAT1-Rx1 and the first radio frequency switch RFS1, so that the first radio frequency switch RFS1 is coupled to the first satellite first receiver SAT1-Rx1 through the LNA. The LNA may be integrated into the aforementioned radio frequency chip or may be independent of the radio frequency chip; this application does not limit this.

[0119] In this situation, continue as follows Figure 7 As shown, the first radio frequency switch RFS1 can be used to connect the first satellite transmitter SAT1-Tx or the first satellite receiver SAT1-Rx1 to the first gating switch S1. When the antenna device 30 has an LNA, the first radio frequency switch RFS1 can be used to connect the first power amplifier 331 or the LNA to the first gating switch S1.

[0120] In this way, the communication chip 32 can send control signals to the first radio frequency switch RFS1. Figure 7 (Indicated by dashed arrows), to control the first RF switch RFS1 to turn on the first power amplifier 331 and the first gating switch S1, so that the communication link of the data to be transmitted by the first satellite communication antenna 311 (including the first satellite transmitter SAT1-Tx, the first power amplifier 331, and the first RF switch RFS1) is connected to the first gating switch S1. Based on this, when the communication chip 32 sends a control signal to the first gating switch S1 ( Figure 7 (Indicated by dashed arrows in the image), when the first selector switch S1 connects the first radio frequency switch RFS1 to the first electrical connection terminal 3101, the radio frequency signal of the first satellite operating frequency band transmitted by the communication chip 32 through the first satellite transmitter SAT1-Tx can be transmitted along... Figure 7The solid arrow in the image points upwards and is transmitted through the communication link to the first electrical connection terminal 3101 to power the first stub 3001, so that the first stub 3001 can be used as the first satellite communication antenna 311 to transmit the radio frequency signal of the first satellite operating frequency band.

[0121] Or, continue as Figure 7 As shown, the communication chip 32 can send a control signal to the first radio frequency switch RFS1 to control the first radio frequency switch RFS1 to conduct the LNA and the first gating switch S1, so that the communication link of the data to be received by the first satellite communication antenna 311 (including the first satellite first receiver SAT1-Rx1, LNA, and the first radio frequency switch RFS1) is connected to the first gating switch S1. Based on this, when the communication chip 32 sends a control signal to the first gating switch S1 to control the first gating switch S1 to conduct the first radio frequency switch RFS1 and the first electrical connection terminal 3101, the first stub 3001 can serve as at least a part of the first satellite communication antenna 311 to receive the radio frequency signal of the first satellite operating frequency band, and along the... Figure 7 The dotted line arrow points downwards and is transmitted to the first receiver SAT1-Rx1 of the first satellite through the communication link to receive the data, so that the communication chip 32 can process the data.

[0122] As can be seen from the above, continuing as follows Figure 7 As shown, the communication chip 32 can select the first stub 3001 as at least a part of the first satellite communication antenna 311, or as at least a part of the first ground network communication antenna 312, to transmit and receive signals by controlling different paths in the first gating switch S1. Furthermore, when the first gating switch S1 is connected to the first electrical connection terminal 3101 and the first radio frequency switch RFS1, the communication chip 32 can select the first stub 3001 as at least a part of the first satellite communication antenna 311 to transmit radio frequency signals in the first satellite operating frequency band, or as at least a part of the first satellite communication antenna 311 to receive radio frequency signals in the first satellite operating frequency band, by controlling different paths in the first radio frequency switch RFS1.

[0123] For example, the first RF switch RFS1 can be an SPMT (e.g., SP4T), or a combination of multiple (e.g., four) SPST switches; this application does not limit this. As an RF switch, the performance indicators of the first RF switch RFS1 may include insertion loss, channel isolation, and power handling capacity under different reflection coefficients, etc. This first RF switch RFS1 will generate significant signal loss. Figure 7It is understood that when the first selection switch S1 selects the first stub 3001 as at least part of the transmit / receive signal of the first ground network communication antenna 312, the aforementioned RF switch is not required in the signal path between the first stub 3001 and the first ground network transmitter GN1-Tx, thus reducing signal loss in this path. Furthermore, located in the clearance area 300 (e.g., Figure 3 The performance parameters of the first gating switch S1 (as shown) can include voltage and current. Therefore, signal loss can be further reduced by adjusting the voltage or current across the first gating switch S1.

[0124] In comparison, among related technologies, such as Figure 8 As shown, two different first antenna signals (e.g., radio frequency signals from the first satellite's operating frequency band) and second antenna signals (e.g., cellular signals) need to be selected by a radio frequency switch (SP4T) before being transmitted to the same radiator. In this case, the communication links of both the first and second antenna signals need to pass through the radio frequency switch (SP4T), resulting in significant signal loss for both antenna signals due to the influence of the radio frequency switch (SP4T).

[0125] In addition, such as Figure 9 As shown, the antenna device 30 in this embodiment may further include a first impedance matching network 41, a first radio frequency (RF) test switch 43, and a second RF test switch 44. The first impedance matching network 41 can perform impedance matching on the communication link of at least one of the first satellite communication antenna 311 or the first ground network communication antenna 312. The first RF test switch 43 can be connected to test instruments to test and adjust relevant parameters of the impedance matching of the communication link of the first satellite communication antenna 311. For example, the relevant parameters and structure of the first impedance matching network 41 can be adjusted using a return loss curve or a Smith chart to achieve impedance matching. Similarly, the second RF test switch 44 can be connected to test instruments to test and adjust relevant parameters of the impedance matching of the communication link of the first ground network communication antenna 312.

[0126] Antenna impedance generally refers to the ratio of voltage to current at the antenna input. Antenna impedance is a measure of the resistance of the antenna to electrical signals. The main purpose of antenna impedance matching is to achieve matching between the antenna and the transmission line. When the antenna and transmission line are matched, the power transmitted from the transmitter to the antenna or from the antenna to the receiver is maximized. At this time, no reflected waves appear on the transmission line, the reflection coefficient is zero, and the standing wave ratio (VSWR) is 1. The quality of the antenna-transmission line matching is measured by the magnitude of the reflection coefficient or VSWR at the antenna input. For transmitting antennas, poor matching will reduce the antenna's radiated power, increase losses on the transmission line, decrease the power capacity of the transmission line, and in severe cases, cause transmitter frequency "pulling," i.e., a change in the oscillation frequency.

[0127] The following provides an example illustrating the configuration of the first impedance matching network 41. In some embodiments of this application, such as... Figure 9 As shown, the first RF test socket 43 can be coupled between the first gating switch S1 and the first satellite transmitter SAT1-Tx. When the antenna device 30 has the aforementioned first RF switch RFS1, the first RF test socket 43 can be coupled between the first gating switch S1 and the first RF switch RFS1. The second RF test socket 44 can be coupled between the first gating switch S1 and the first ground network transmitter GN1-Tx. For example, when the antenna device 30 includes a first power amplifier 331, the second RF test socket 44 can be coupled between the first gating switch S1 and the first power amplifier 331. Furthermore, continuing as... Figure 9 As shown, the first impedance matching network 41 can be coupled to at least one of the first RF test socket 43 or the second RF test socket 44, and to the first selection switch S1. Wherein, Figure 9 This example illustrates the situation by taking the case where the first impedance matching network 41 is coupled to both the first RF test socket 43 and the second RF test socket 44.

[0128] In this situation, while the first gating switch S1 turns on the first electrical connection terminal 3101 and the first radio frequency switch RFS1, the first gating switch S1 will disconnect the first electrical connection terminal 3101 and the first ground network transmitter GN1-Tx. This ensures that the signal from the first ground network transmitter GN1-Tx will not affect the communication link of the first satellite communication antenna 311 (including the first satellite transmitter SAT1-Tx, the first power amplifier 331, the first radio frequency switch RFS1, the first impedance matching network 41, the first gating switch S1, and the first electrical connection terminal 3101). This allows the impedance matching effect of the communication link of the first satellite communication antenna 311 to match the structure and related parameters of the first impedance matching network 41, thereby increasing the radiated power of the first satellite communication antenna 311 and reducing signal loss.

[0129] Similarly, while the first gating switch S1 connects the first electrical connection terminal 3101 and the first ground network transmitter GN1-Tx, it also disconnects the first electrical connection terminal 3101 and the first satellite transmitter SAT1-Tx. This prevents the signal from the first satellite transmitter SAT1-Tx from affecting the communication link of the first ground network communication antenna 312 (including the first ground network transmitter GN1-Tx, the second power amplifier 332, the first impedance matching network 41, the first gating switch S1, and the first electrical connection terminal 3101). Consequently, the impedance matching effect of the communication link of the first ground network communication antenna 312 matches the structure and related parameters of the first impedance matching network 41, thereby increasing the radiated power of the first ground network communication antenna 312 and reducing signal loss. In this way, by setting the first gating switch S1, the isolation between the communication links of the first satellite communication antenna 311 and the first ground network communication antenna 312 can be improved, thus reducing signal loss.

[0130] The above example illustrates how the first impedance matching network 41 can be coupled to at least one of the first RF test socket 43 or the second RF test socket 44, and the first selection switch S1. In other embodiments of this application, such as Figure 10 As shown, the first impedance matching network 41 may include two parts, namely a first part 41a and a second part 41b. The first part 41a of the first impedance matching network may be coupled to at least one of the first RF test socket 43 or the second RF test socket 44, and to the first selection switch S1. The second part 41b of the first impedance matching network may be coupled to the first selection switch S1 and the first electrical connection terminal 3101. Alternatively, as another example, such as... Figure 11 As shown, the first impedance matching network 41 is coupled between the first gating switch S1 and the first electrical connection terminal 3101. The technical effects of the first impedance matching network 41 and the first gating switch S1 are the same as described above, and will not be repeated here.

[0131] As described above, the communication chip 32 has a first satellite transmitter SAT1-Tx and a first satellite receiver SAT1-Rx1 that match the first satellite communication antenna 311. In this case, the first satellite communication antenna 311 can be an antenna with 1T1R functionality. Here, 1T in 1T1R refers to a transmitter (i.e., the first satellite transmitter SAT1-Tx), and 1R refers to a receiver (i.e., the first satellite receiver SAT1-Rx1).

[0132] In other embodiments of this application, the first satellite communication antenna 311 described above can be an antenna with 1T2R functionality. For example, ... Figure 12As shown, the first satellite communication antenna 311 may further include a second stub 3002, which may have a second electrical connection terminal 3201. The second stub 3002 may be spaced apart from the first stub 3001, i.e., there is a gap between the first stub 3001 and the second stub 3002, so that the first stub 3001 and the second stub 3002 are not connected or in contact with each other. For example, other stubs may be provided between the first stub 3001 and the second stub 3002, or no other stubs may be provided between the first stub 3001 and the second stub 3002; this application does not limit this. Figure 12 This is merely an illustrative example of the relative positions of the first branch 3001 and the second branch 3002, and does not constitute a limitation on the placement of the first branch 3001 and the second branch 3002. Furthermore, the second branch 3002 can be as follows... Figure 12 The second branch 3002 may be located to the left of the first branch 3001, or it may be located to the right of the first branch 3001. This application does not limit this.

[0133] In addition, continue as Figure 12 As shown, the communication chip 32 also has a first satellite second receiver SAT1-Rx2. This first satellite second receiver SAT1-Rx2 is used to receive radio frequency signals from the first satellite's operating frequency band (e.g., downlink band 2170 / MHz to 2200 / MHz). The first satellite second receiver SAT1-Rx2 can be coupled to the second electrical connection terminal 3201 of the second branch 3002. In this case, the 2R in the above 1T2R refers to two receivers (i.e., the first satellite first receiver SAT1-Rx1 and the first satellite second receiver SAT1-Rx2).

[0134] In this configuration, when the first satellite communication antenna 311 transmits radio frequency signals in the operating frequency band of the first satellite, the first stub 3001 is operational to transmit these signals. When the first satellite communication antenna 311 receives radio frequency signals in the operating frequency band of the first satellite, the first stub 3001 and the second stub 3002 can simultaneously be operational to receive these signals. This expands the beamwidth and gain of the first satellite communication antenna 311, improving its sensitivity as a receiving antenna and making it easier for the electronic device 01 to perform satellite alignment.

[0135] For example, when electronic device 01 is as follows Figure 13In the case of the candybar phone shown, a portion of the top frame 1011 of the metal frame of the electronic device 01 can be reused as a first branch 3001, and a portion of the top frame 1011 and a portion of the second side frame 1014 can be reused as a second branch 3002. When there are no other branches between the first branch 3001 and the second branch 3002, the gap between the first branch 3001 and the second branch 3002 can be filled with a dielectric layer, so that the first branch 3001 and the second branch 3002 are spaced apart. Figure 13 This example illustrates the situation with the second branch 3002 located to the left of the first branch 3001. In other embodiments, the second branch 3002 may also be located to the right of the first branch 3001. In summary, the electronic device 01 may include a first satellite communication antenna 311 (e.g., a high-orbit satellite communication antenna) and a first ground network communication antenna 312 (e.g., a cellular antenna). The first satellite communication antenna 311 has an 1T2R (Integrated Telemetry and Recognition) function.

[0136] Or, for another example, when electronic device 01 is as follows: Figure 14 In the folding device shown, the first metal frame 101a of the electronic device 01 may include a first branch 3001, that is, a portion of the first metal frame 101a is reused as the first branch 3001. The first branch 3001 may be located in the middle of the top frame of the first metal frame 101a, that is, the first branch 3001 is the middle branch of the top frame (upper end of the first metal frame 101a) of the first metal frame 101a. The branches located on both sides of the first branch 3001 in the top frame of the first metal frame 101a may have gaps with the first branch 3001.

[0137] In addition, continue as Figure 14 As shown, the second metal frame 101b of the electronic device 01 may include a second branch 3002, that is, a portion of the second metal frame 101b is reused as the second branch 3002. The second branch 3002 may be located in the middle of the top frame (upper end of the second metal frame 101b) of the second metal frame 101b, that is, the second branch 3002 is the middle branch of the top frame of the second metal frame 101b. The branches on both sides of the second branch 3002 in the top frame of the second metal frame 101b may have gaps with the second branch 3002. The second electrical connection terminal 3201 of the second branch 3002 may be electrically connected to the first satellite second receiver terminal SAT1-Rx2 of the communication chip 32 through a circuit board, such as a flexible printed circuit (FPC), which passes through the shaft (i.e., through the pivot 11).

[0138] Based on this, compared to the scheme of placing the first stub 3001 and the second stub 3002 on the same metal frame, by placing the first stub 3001 and the second stub 3002 on different metal frames (e.g., the first metal frame 101a and the second metal frame 101b mentioned above), the first metal frame 101a and the second metal frame 101b can be provided with larger dimensions to serve as the first stub 3001 and the second stub 3002 respectively, thereby increasing the physical length of the first stub 3001 and the second stub 3002, thereby achieving the purpose of increasing the antenna aperture and gain.

[0139] In this situation, continue as follows Figure 14 As shown, since a portion of the top edge of the first metal frame 101a is reused as the first branch 3001, and a portion of the top edge of the second metal frame 101b is reused as the second branch 3002, the first branch 3001 and the second branch 3002 can be located at the same end of the rotating shaft 11, that is, both the first branch 3001 and the second branch 3002 are disposed at the upper end of the electronic device 01. In this way, when the first satellite communication antenna 311 receives (Rx) the first satellite operating frequency band through the first branch 3001, it is... Figure 15 As can be seen in (b), the darker part of the antenna pattern, i.e., the part with higher gain, covers the top edge of the first metal frame 101a. Furthermore, when the first satellite communication antenna 311 receives (Rx) the first satellite's operating frequency band through the second stub 3002, it is... Figure 15 As can be seen in (c), the darker part of the antenna pattern, i.e. the part with higher gain, covers the top edge of the second metal frame 101b.

[0140] Continue as Figure 14 As shown, the first stub 3001 and the second stub 3002 can be symmetrically arranged about the rotation axis 11. In this way, when the first satellite communication antenna 311 transmits (Tx) the first satellite's operating frequency band, as... Figure 15 The radiation pattern shown in (a) is similar to that when the first satellite communication antenna 311 receives (Rx) the operating frequency band of the first satellite, as shown in Figure (a). Figure 15 (b) and Figure 15 As shown in (c), the antenna pattern is omnidirectional, achieving better circular polarization coverage with a larger coverage area, and the gain distribution (i.e., color depth) of the various patterns is relatively consistent. This indicates that the first satellite communication antenna 311 has consistent radiation performance when transmitting or receiving the first satellite's operating frequency band. Therefore, when using the first satellite communication antenna 311 for satellite communication, users can reduce the need to move their phones to change the satellite alignment angle, making satellite alignment easier.

[0141] In addition, continue as Figure 14As shown, when there is a gap between the first branch 3001 (or the second branch 3002) and other branches on both sides of the branch, both ends of the first branch 3001 (or the second branch 3002) can be open ends. In this case, the first electrical connection end 3101 of the first branch 3001 can be located at the end of the first branch 3001 away from the second branch 3002, thereby allowing the first electrical connection end 3101 to be located at the open end of the first branch 3001, which is beneficial for increasing the antenna aperture. Similarly, the second electrical connection end 3201 can be located at the end of the second branch 3002 away from the first branch 3001, thereby allowing the second electrical connection end 3201 to be located at the open end of the second branch 3002, which also increases the antenna aperture. In the embodiments of this application, the open end may not be grounded, and the open end is not electrically connected to other conductors. The open end may also be called a free end, an open end, or an open circuit end. It should be understood that in some embodiments, other conductors can be coupled through an open terminal to transfer coupled energy (which can be understood as transferring current).

[0142] The above description uses an antenna structure 31 comprising a first satellite communication antenna 311 and a first ground network communication antenna 312 as an example. The first satellite communication antenna 311 can serve as a high-orbit satellite communication antenna for transmitting and receiving radio frequency signals in the operating frequency band of a first satellite (e.g., uplink band 1980 MHz to 2010 MHz and downlink band 2170 MHz to 2200 MHz). Furthermore, the first satellite communication antenna 311 can have 1T1R or 1T2R functionality. In other embodiments of this application, the first satellite communication antenna 311 may also have two or more satellite transmitters and two or more satellite receivers, which will not be elaborated upon here. Additionally, the first ground network communication antenna 312 can be a cellular antenna for transmitting and receiving signals in the cellular communication frequency band.

[0143] In other embodiments of this application, such as Figure 16 As shown, the antenna structure 31 may further include a second satellite communication antenna 341, which may include the aforementioned second stub 3002. Furthermore, the communication chip 32 may have a second satellite transmitter SAT2-Tx and a second satellite first receiver SAT2-Rx1. For example, the communication chip 32 may include a first sub-chip 3211 and a second sub-chip 3222. The first sub-chip 3211 may include... Figure 4The diagram shows a first satellite communication chip 321 and a first ground network communication chip 322. In this case, the first sub-chip 3211 may have the aforementioned first satellite transmitter SAT1-Tx, first satellite first receiver SAT1-Rx1, first satellite second receiver SAT1-Rx2, and first ground network transmitter GN1-Tx. The second sub-chip 3222 may have the aforementioned second satellite transmitter SAT2-Tx and second satellite first receiver SAT2-Rx1; this second sub-chip 3222 may be referred to as the second satellite communication chip.

[0144] Furthermore, in some embodiments of this application, when the second satellite communication antenna 341 is a low-Earth orbit satellite communication antenna, the second satellite transmitter SAT2-Tx is used to transmit radio frequency signals in the second satellite's operating frequency band (e.g., uplink band 1668 / MHz to 1675 / MHz), and the second satellite receiver SAT2-Rx1 is used to receive radio frequency signals in the second satellite's operating frequency band (e.g., downlink band 1518 / MHz to 1525 / MHz). In this case, the second satellite communication antenna 341 has one transmitter, namely the second satellite transmitter SAT2-Tx, and one receiver, namely the second satellite first receiver SAT2-Rx1. Therefore, the second satellite communication antenna 341 can realize the 1T1R function.

[0145] As described above, the second satellite communication antenna 341 may include the aforementioned second stub 3002, which serves as both the transmitting and receiving antenna of the second satellite communication antenna 341. Furthermore, the first satellite communication antenna 311 may also include the second stub 3002, which serves as the receiving antenna of the first satellite communication antenna 311. Therefore, the first satellite communication antenna 311, serving as a high-orbit satellite antenna, and the second satellite communication antenna 341, serving as a low-orbit satellite antenna, can share the same stub, namely the aforementioned second stub 3002, thereby improving the space utilization of the electronic device 01. In other embodiments of this application, the first satellite communication antenna 311 may be a low-orbit satellite antenna, and the second satellite communication antenna 341 may be a high-orbit satellite antenna; this application does not limit this. For ease of explanation, the following examples will use the scenario where the first satellite communication antenna 311 can be a high-orbit satellite antenna and the second satellite communication antenna 341 can be a low-orbit satellite antenna.

[0146] Based on the common branch of the first satellite communication antenna 311 and the second satellite communication antenna 341, in order to achieve common feeding of the first satellite communication antenna 311 and the second satellite communication antenna 341, the following continues... Figure 16As shown, the antenna device 30 may further include a second radio frequency switch RFS2. The second radio frequency switch RFS2 may be coupled between the second receiver SAT1-Rx2 of the first satellite and the second electrical connection terminal 3201. Furthermore, the second radio frequency switch RFS2 is also coupled between the second transmitter SAT2-Tx of the second satellite and the second electrical connection terminal 3201, and also coupled between the first receiver SAT2-Rx1 of the second satellite and the second electrical connection terminal 3201. The aforementioned second radio frequency switch RFS2 can be used to connect the second receiver SAT1-Rx2 of the first satellite, the second transmitter SAT2-Tx of the second satellite, or the first receiver SAT2-Rx1 of the second satellite to the second electrical connection terminal 3201. For example, the aforementioned second radio frequency switch RFS2 may be the aforementioned SPMT switch, such as an SP4T switch. Alternatively, it may be a combination of multiple SPST switches; this application does not limit this.

[0147] Continue as Figure 16 As shown, since the second RF switch RFS2 is coupled to the second receiver SAT1-Rx2, the second transmitter SAT2-Tx, and the first receiver SAT2-Rx1 of the first satellite, a control signal is needed to control one channel of the second RF switch RFS2 to be turned on, so that one of the three channels can be selected to be connected to the second electrical connection terminal 3201. To achieve the above function, for example, the antenna device 30 may also include an application processor (AP) and a double pole multi throw (SPMT) switch, such as a double pole double throw (DPDT) switch.

[0148] In this case, the AP can control the DPMP to select either the first sub-chip 3211 or the second sub-chip 3222 to control the DPMT switch as needed. For example, when the second stub 3002 needs to be used as the receiving antenna of the first satellite communication antenna 311, the AP can select the first sub-chip 3211 to control the DPMT switch according to the above requirements, so that the control signal output by the DPMT to the second RF switch RFS2 can control the second RF switch RFS2 to connect the first satellite second receiver terminal SAT1-Rx2 of the first sub-chip 3211 to the second electrical connection terminal 3201.

[0149] Alternatively, when the second branch 3002 needs to be used as the transmitting or receiving antenna of the second satellite communication antenna 341, the AP can select the second sub-chip 3222 to control the DPMT switch according to the above requirements, so that the control signal output by the DPMT to the second radio frequency switch RFS2 can control the second radio frequency switch RFS2 to connect the second satellite transmitting end SAT2-Tx or the second satellite first receiving end SAT2-Rx1 of the second sub-chip 3222 to the second electrical connection end 3201.

[0150] In addition, continue as Figure 16 As shown, the antenna device 30 may further include a third RF test socket 45 and a second impedance matching network 46. The third RF test socket 45 and the second impedance matching network 46 can be connected in series between the second RF switch RFS2 and the second electrical connection terminal 3201 of the second stub 3002. The second impedance matching network 46 can perform impedance matching on the communication link of the second satellite communication antenna 341. The third RF test socket 45 can be connected to test instruments to test and adjust relevant parameters of the impedance matching of the communication link of the second satellite communication antenna 341.

[0151] Figure 16 This example illustrates the concept of an electronic device as a folding device, with the first branch 3001 and the second branch 3002 located on either side of the pivot 11 of the electronic device. Based on this, since the first satellite communication antenna 311 and the first ground network communication antenna 312 share the first branch 3001, when the first ground network communication antenna 312 transmits and receives radio frequency signals in the first ground network operating frequency band, the first satellite communication antenna 311 can be in a non-operating state (i.e., not transmitting or receiving signals). Furthermore, when the electronic device 01 is in... Figure 17 In the folded state shown, the first metal frame 101a and the second metal frame 101b are stacked, causing the first branch 3001 in the first metal frame 101a and the second branch 3002 in the second metal frame 101b to approach each other and thus couple. Therefore, when the first ground network communication antenna 312 transmits and receives radio frequency signals in the first ground network operating frequency band, the second branch 3002 can act as a parasitic antenna for the first ground network communication antenna 312, thereby increasing the size of the first ground network communication antenna 312 and improving its antenna aperture and gain. Therefore, when the first ground network communication antenna 312 transmits and receives radio frequency signals in the first ground network operating frequency band, the second satellite communication antenna 341 can also be in a non-operating state (i.e., not transmitting or receiving signals).

[0152] Based on this, when electronic device 01 is in Figure 17In the folded state shown, when the first ground network communication antenna 312 transmits and receives radio frequency signals in the first ground network operating frequency band, in order to prevent the second impedance matching network 46 from affecting the signal on the second branch 3002, which is a parasitic antenna of the first ground network communication antenna 312, the antenna device 30 may further include, as shown in the figure. Figure 16 The second gating switch S2 is shown. The second gating switch S2 can be coupled between the second RF switch RFS2 and the second electrical connection terminal 3201. The second gating switch S2 can be located in the clearance area 300 of the antenna device 30 (e.g., Figure 3 (As shown).

[0153] In this situation, continue as follows Figure 16 As shown, the third RF test socket 45 can be coupled between the second gating switch S2 and the second RF switch RFS2. For example, at least a portion of the second impedance matching network 46 can be coupled to the side of the second gating switch S2 away from the second electrical connection terminal 3201; for instance, the second impedance matching network 46 is coupled between the second gating switch S2 and the third RF test socket 45. Thus, when the first gating switch S1 connects the first ground network transmitter GN1-Tx to the first electrical connection terminal 3101 of the first stub 3001, the second gating switch S2 is used to disconnect at least a portion of the second impedance matching network 46 from the second electrical connection terminal 3201 of the second stub 3002. This allows the electronic device 01 to... Figure 17 In the folded state shown, the first stub 3001 and the second stub 3002 are coupled to each other, so that when the second stub 3002 acts as a parasitic antenna of the first ground network communication antenna 312 to transmit and receive radio frequency signals in the first ground network operating frequency band (e.g., cellular communication frequency band), the signal on the second stub 3002 will not be affected by the second impedance matching network 46, thereby achieving the purpose of improving the aperture and gain of the first ground network communication antenna 312. Alternatively, the first part of the second impedance matching network 46 is coupled between the second gating switch S2 and the second electrical connection terminal 3201, and the second part of the second impedance matching network 46 is coupled between the second gating switch S2 and the third radio frequency test socket 45.

[0154] The above example illustrates how at least a portion of the second impedance matching network 46 can be coupled to the side of the second selector switch S2 away from the second electrical connection terminal 3201. In other embodiments of this application, at least a portion of the second impedance matching network 46 can be coupled between the second selector switch S2 and the second electrical connection terminal 3201. In this case, the technical effects of the second selector switch S2, the second impedance matching network 46, and the third RF test socket 45 are the same as described above, and will not be repeated here.

[0155] The above is an example illustrating the implementation of 1T1R functionality using the second satellite communication antenna 341. In other embodiments of this application, the second satellite communication antenna 341 can also implement 1T2R functionality. For example, as shown... Figure 18 As shown, the second satellite communication antenna 341 also includes a third stub 3003, which may have a third electrical connection terminal 3301. This third stub 3003 may be spaced apart from the first stub 3001 and the second stub 3002. The way in which the third stub 3003 is spaced apart from the first stub 3001 and the second stub 3002 is similar to the way the first stub 3001 and the second stub 3002 are spaced apart, and will not be elaborated further here.

[0156] In addition, continue as Figure 18 As shown, the communication chip, such as the second sub-chip 3222 in the communication chip, may also have a second satellite second receiver SAT2-Rx2, which is used to receive radio frequency signals from the second satellite's operating frequency band (e.g., downlink frequency band 1518 / MHz to 1525 / MHz). The second satellite second receiver SAT2-Rx2 may be coupled to the third electrical connection terminal 3301 of the third branch 3003.

[0157] In this configuration, when the second satellite communication antenna 341 transmits radio frequency signals in the second satellite's operating frequency band, the second stub 3002 is operational to transmit these signals. When the second satellite communication antenna 341 receives these signals, both the second stub 3002 and the third stub 3003 are simultaneously operational to receive them. This allows the second satellite communication antenna 341 to have a 1T2R (One-to-Two-R) function, expanding its receiving beamwidth and gain, and increasing its sensitivity as a receiving antenna, thus making it easier for the electronic device 01 to perform satellite alignment.

[0158] in, Figure 18This example illustrates the direct coupling of the second satellite's second receiver SAT2-Rx2 with the third electrical connection 3301 of the third stub 3003. In other embodiments of this application, a radio frequency switch, such as an SP4T, can be coupled between the second satellite's second receiver SAT2-Rx2 and the third electrical connection 3301. This allows the user to control the path of the radio frequency switch to connect the second satellite's second receiver SAT2-Rx2 and the third electrical connection 3301, enabling the second satellite communication antenna 341 to have a 1T2R function. Alternatively, the second satellite's second receiver SAT2-Rx2 can be disconnected from the third electrical connection 3301, enabling the second satellite communication antenna 341 to have a 1T1R function.

[0159] As can be seen from the above, if Figure 18 As shown, when both the first satellite communication antenna 311 and the second satellite communication antenna 341 have 1T2R functionality, the first satellite communication antenna 311 includes a first stub 3001 and a second stub 3002. The first stub 3001 can receive and transmit radio frequency signals in the first satellite's operating frequency band, and the second stub 3002 can receive radio frequency signals in the first satellite's operating frequency band. In the case of a folding device, the first stub 3001 and the second stub 3002 are respectively disposed on the first metal frame 101a and the second metal frame 101b. Furthermore, the first ground network communication antenna 312 shares the first stub 3001 with the first satellite communication antenna 311. In addition, the second satellite communication antenna 341 includes a second stub 3002 and a third stub 3003. The second stub 3002 is used to receive and transmit radio frequency signals in the second satellite's operating frequency band, and the third stub 3003 is used to receive radio frequency signals in the second satellite's operating frequency band. The second branch 3002 and the third branch 3003 are both located on the second metal frame 101b.

[0160] In other embodiments of this application, such as Figure 19 As shown, when the electronic device 01 is a folding device, the antenna structure 31 of the electronic device 01 may only include a first satellite communication antenna 311 and a second satellite communication antenna 341. Both the first satellite communication antenna 311 and the second satellite communication antenna 341 have the aforementioned 1T2R function, and the arrangement of the first satellite communication antenna 311 and the second satellite communication antenna 341 is the same as... Figure 18 The setup method shown is similar and will not be repeated here. Or, as... Figure 20As shown, when the antenna structure 31 may include only the first satellite communication antenna 311 and the second satellite communication antenna 341, the first satellite communication antenna 311 has the aforementioned 1T2R function, and the second satellite communication antenna 341 may have the 1T1R function. Alternatively, the first satellite communication antenna 311 has the aforementioned 1T1R function, and the second satellite communication antenna 341 may have the 1T2R function.

[0161] Continue as Figure 19 As shown, at any given time, only one of the first satellite communication antenna 311 and the second satellite communication antenna 341 can be in an operational state. When either the first satellite communication antenna 311 or the second satellite communication antenna 341 is in an operational state, the antenna in that operational state can be used to realize at least one of satellite calls or satellite short message transmission and reception. The operational state of the antenna refers to the state in which the antenna can receive and transmit signals. When the first satellite communication antenna 311 is operational and the second satellite communication antenna 341 is in an inoperable state, the second branch 3002 of the second satellite communication antenna 341 can be reused as a receiving antenna of the first satellite communication antenna 311, thereby enabling the first satellite communication antenna 311 to possess the aforementioned 1T2R function. Furthermore, when a user selects a satellite communication antenna with 1T2R function for satellite calls, the receiving beamwidth and gain of the satellite communication antenna can be expanded, improving the sensitivity of the satellite communication antenna when used as a receiving antenna. The configuration of the branches of the first satellite communication antenna 311 and the second satellite communication antenna 341 used as receiving and transmitting antennas is similar and will not be elaborated here.

[0162] Alternatively, in some other embodiments of this application, such as Figure 21 As shown, the first satellite communication antenna 311 includes a first stub 3001 and a second stub 3002. The first stub 3001 can receive and transmit radio frequency signals in the operating frequency band of the first satellite, and the second stub 3002 can receive radio frequency signals in the operating frequency band of the first satellite. The second satellite communication antenna 341 includes a second stub 3002 and a first stub 3001. The second stub 3002 is used to receive and transmit radio frequency signals in the operating frequency band of the second satellite. Furthermore, the second satellite second receiver terminal SAT2-Rx2 of the second sub-chip 3222 is coupled to the first electrical connection terminal 3101 of the first stub 3001, so that the first stub 3001 receives radio frequency signals in the operating frequency band of the second satellite. In this case, both the first satellite communication antenna 311 and the second satellite communication antenna 341 have 1T2R functionality. For example, the first branch 3001 on the first metal frame 101a and the second branch 3002 on the second metal frame 101b can be symmetrically arranged about the pivot 11 and are both located at the upper end of the pivot 11.

[0163] Based on this, in the case where the first satellite communication antenna 311 includes a first stub 3001 and a second stub 3002, and the second satellite communication antenna 341 includes a second stub 3002 and a first stub 3001, such as Figure 22 As shown, the antenna structure 31 may further include a first ground network communication antenna 312, which can reuse the aforementioned first branch 3001 with the first satellite communication antenna 311 and the second satellite communication antenna 341. The arrangement and technical effects of the first ground network communication antenna 312 are the same as described above, and will not be repeated here.

[0164] The above example illustrates the use of a folding device as an example, where the antenna structure 31 includes a first satellite communication antenna 311, a second satellite communication antenna 341, and a first ground network communication antenna 312. In other embodiments of this application, such as... Figure 23 As shown, the electronic device 01 can be a candybar phone. Similarly, the first satellite communication antenna 311 includes a first branch 3001 and a second branch 3002, the second satellite communication antenna 341 includes a second branch 3002 and a first branch 3001, and the first ground network communication antenna 312 can reuse the first branch 3001 with the first satellite communication antenna 311 and the second satellite communication antenna 341. As can be seen from the above, the first branch 3001 is a branch shared by the first satellite communication antenna 311, the second satellite communication antenna 341, and the first ground network communication antenna 312. Therefore, in order to improve the gain of the above antennas and facilitate the satellite antenna's satellite alignment operation, the first branch 3001 can be set as the middle branch of the top frame 1011 in the metal frame. Figure 23 This description is based on the example that both the first satellite communication antenna 311 and the second satellite communication antenna 341 have 1T2R functionality. This application does not limit the number of branches of the first satellite communication antenna 311 and the second satellite communication antenna 341 used as receiving antennas and branches used as transmitting antennas.

[0165] Furthermore, in some embodiments of this application, such as Figure 24As shown, antenna structure 31 may further include a third satellite communication antenna 351. This third satellite communication antenna 351 may include a fourth stub 3004, which has a fourth electrical connection terminal 3401. Communication chip 32 may also have a third satellite transmitter SAT3-Tx and a third satellite receiver SAT3-Rx. For example, the aforementioned third satellite communication antenna 351 may be a high-orbit satellite communication antenna, and this third satellite communication antenna 351 may be used solely for short message transmission and reception; this third satellite communication antenna may also be referred to as a satellite short message antenna. In this case, the third satellite transmitter SAT3-Tx is used to transmit radio frequency signals in the third satellite operating frequency band (uplink band 610 / MHz to 1626 / MHz), and the third satellite receiver SAT3-Rx is used to receive radio frequency signals in the third satellite operating frequency band (downlink band 2483 / MHz to 2500 / MHz).

[0166] Example, Figure 24 In addition to the first sub-chip 3211 and the second sub-chip 3222 described above, the communication chip 32 shown may also include a third sub-chip 3233. This third sub-chip 3233 may have the aforementioned third satellite transmitter SAT3-Tx and third satellite receiver SAT3-Rx. Furthermore, to select between the third satellite transmitter SAT3-Tx and the third satellite receiver SAT3-Rx, the antenna device 30 may also include a third radio frequency switch RFS3. The third radio frequency switch RFS3 may be coupled between the third satellite transmitter SAT3-Tx and the fourth electrical connection terminal 3401 of the fourth branch 3004. The third radio frequency switch RFS3 is also coupled between the third satellite receiver SAT3-Rx and the fourth electrical connection terminal 3401. This third radio frequency switch RFS3 can be used to connect either the third satellite transmitter SAT3-Tx or the third satellite receiver SAT3-Rx to the fourth electrical connection terminal 3401. For example, the third radio frequency switch RFS3 mentioned above can be the SPMT switch, such as the SP4T switch. Alternatively, it can be a combination of multiple SPST switches, which is not limited in this application.

[0167] In this scenario, when the third sub-chip 3233 controls the third RF switch RFS3 to connect the third satellite transmitter SAT3-Tx to the fourth electrical connection 3401, the fourth stub 3004 can function as the transmitting antenna of the third satellite communication antenna 351, transmitting RF signals in the aforementioned third satellite operating frequency band (uplink band 610 / MHz~1626 / MHz). When the third sub-chip 3233 controls the third RF switch RFS3 to connect the third satellite receiver SAT3-Rx to the fourth electrical connection 3401, the fourth stub 3004 can function as the receiving antenna of the third satellite communication antenna 351, receiving RF signals in the aforementioned third satellite operating frequency band (downlink band 2483 / MHz~2500 / MHz).

[0168] Based on this, in some embodiments of this application, when electronic device 01 is as follows: Figure 24 In the case of the folding device shown, the antenna structure 31 of the electronic device 01 may include a first ground network communication antenna 312, a first satellite communication antenna 311, a second satellite communication antenna 341, and the aforementioned third satellite communication antenna 351. As can be seen from the above, the first satellite communication antenna 311 and the second satellite communication antenna 341 can be used for voice calls and sending and receiving short messages (or short messages). The third satellite communication antenna 351 is only used for sending and receiving short messages.

[0169] For example, the first satellite communication antenna 311 may include a first stub 3001 and a second stub 3002. The first stub 3001 serves as the transceiver antenna of the first satellite communication antenna 311, and the second stub 3002 serves as the receiving antenna of the first satellite communication antenna 311, so that the first satellite communication antenna 311 has the aforementioned 1T2R function. The second satellite communication antenna 341 may include a second stub 3002 and a third stub 3003. The second stub 3002 may also be multiplexed as the transceiver antenna of the second satellite communication antenna 341, and the third stub 3003 may serve as the receiving antenna of the second satellite communication antenna 341, so that the second satellite communication antenna 341 has the 1T2R function.

[0170] Continue as Figure 24 As shown, the fourth branch 3004 of the third satellite communication antenna 351 can be spaced apart from the first branch 3001. When the antenna structure 31 further includes a second branch 3002 and a third branch 3003, the fourth branch 3004, the second branch 3002, and the third branch 3003 are all spaced apart. The different branch spacing arrangements are the same as described above and will not be repeated here. For example, the first branch 3001 can be disposed on the first metal frame 101a, and the second branch 3002, the fourth branch 3004, and the third branch 3003 can be disposed on the second metal frame 101b.

[0171] Furthermore, when the third satellite communication antenna 351 transmits and receives radio frequency signals in the operating frequency band of the third satellite, the second satellite communication antenna 341 and the first satellite communication antenna 311 can be in a non-operating state. At this time, the second gating switch S2 can be controlled to disconnect at least a portion of the second impedance matching network 46 from the second electrical connection terminal 3201 of the second stub 3002. In this way, the second stub 3002 and the fourth stub 3004 can couple to each other, so that when the second stub 3002 acts as a parasitic antenna of the third satellite communication antenna 351 to transmit and receive radio frequency signals in the operating frequency band of the third satellite, the signal on the second stub 3002 will not be affected by the second impedance matching network 46, thereby achieving the purpose of improving the aperture and gain of the third satellite communication antenna 351.

[0172] Alternatively, in some other embodiments of this application, when electronic device 01 is as follows: Figure 25 In the case of the folding device shown, the antenna structure 31 of the electronic device 01 may include a first satellite communication antenna 311, a second satellite communication antenna 341, and the aforementioned third satellite communication antenna 351. The first satellite communication antenna 311 has the aforementioned 1T2R function, and the second satellite communication antenna 341 may have a 1T1R function. The third satellite communication antenna 351 and the second satellite communication antenna 341 are located on the same metal frame, for example, on the second metal frame 101b.

[0173] Or, in electronic device 01, for example... Figure 26 In the case of the folding device shown, and the antenna structure 31 of the electronic device 01, which may include a first satellite communication antenna 311, a second satellite communication antenna 341, and the aforementioned third satellite communication antenna 351, the first satellite communication antenna 311 and the second satellite communication antenna 341 may share a first branch 3001, and at least one of the first satellite communication antenna 311 and the second satellite communication antenna 341 may have the aforementioned 1T2R function. Furthermore, the third satellite communication antenna 351 may be located on the same metal frame as the first satellite communication antenna 311 and the second satellite communication antenna 341, for example, on the second metal frame 101b.

[0174] Alternatively, in some other embodiments of this application, when electronic device 01 is as follows: Figure 27 In the case of the folding device shown, the antenna structure 31 of the electronic device 01 may include a first satellite communication antenna 311 and a satellite short message antenna (i.e., a third satellite communication antenna 351). The first satellite communication antenna 311 has the aforementioned 1T2R function (or the aforementioned 1T1R function), and is used to realize at least one of satellite calls or satellite short message transmission and reception. The second branch 3002 of the third satellite communication antenna 351 and the first satellite communication antenna 311 is located on the same metal frame, for example, on the second metal frame 101b. For example, at any given time, only one of the first satellite communication antenna 311 and the satellite short message antenna (i.e., the third satellite communication antenna 351) is in an active state.

[0175] Alternatively, in some other embodiments of this application, when electronic device 01 is as follows: Figure 28 In the case of the folding device shown, the antenna structure 31 of the electronic device 01 may include a second satellite communication antenna 341 and a third satellite communication antenna 351. The second satellite communication antenna 341 has the aforementioned 1T1R function (or the aforementioned 1T2R function). The third satellite communication antenna 351 and the second satellite communication antenna 341 are located on the same metal frame, for example, on the second metal frame 101b.

[0176] The above example uses a folding device as an example of electronic device 01. In other embodiments of this application, electronic device 01 can also be, for example, a folding device. Figure 29 The illustrated candybar phone. In this case, the antenna structure 31 of the electronic device 01 may include a first satellite communication antenna 311, a second satellite communication antenna 341, and the aforementioned third satellite communication antenna 351 (including a fourth branch 3004). The first satellite communication antenna 311 and the second satellite communication antenna 341 may share the first branch 3001, and at least one of the first satellite communication antenna 311 and the second satellite communication antenna 341 may have the aforementioned 1T2R function. The top frame 1011 of the metal frame of the electronic device 01 may include at least a portion of the aforementioned first branch 3001, second branch 3002, and fourth branch 3004, wherein the second branch 3002 may be located between the first branch 3001 and the fourth branch 3004.

[0177] Furthermore, in the case where the antenna structure 31 includes the aforementioned fourth branch 3004, such as Figure 30 As shown, the antenna structure 31 may further include a satellite positioning antenna 361, which may include the aforementioned fourth branch 3004. In this case, the satellite positioning antenna 361 may share the fourth branch 3004 with the third satellite communication antenna 351. Furthermore, the third sub-chip 3233 in the communication chip 32 also has a positioning satellite receiver SAT4-Rx, which is used to receive radio frequency signals from the fourth satellite's operating frequency band. For example, the aforementioned satellite positioning antenna 361 may be a Global Positioning System (GPS) antenna or a BeiDou satellite antenna; in this case, the fourth satellite's operating frequency band may be the communication frequency band of the GPS antenna or the BeiDou antenna. Additionally, the aforementioned third radio frequency switch RFS3 is also coupled between the positioning satellite receiver SAT4-Rx and the fourth electrical connection terminal 3401. The third radio frequency switch RFS3 can be used to connect the third satellite transmitter SAT3-Tx, the third satellite receiver SAT3-Rx, or the positioning satellite receiver SAT4-Rx to the fourth electrical connection terminal 3401.

[0178] In this way, when the third sub-chip 3233 controls the third RF switch RFS3 to connect the third satellite transmitter SAT3-Tx or the third satellite receiver SAT3-Rx to the fourth electrical connection terminal 3401, the fourth stub 3004 can act as the transceiver antenna of the third satellite communication antenna 351, transmitting RF signals in the aforementioned third satellite operating frequency band. When the third sub-chip 3233 controls the third RF switch RFS3 to connect the positioning satellite receiver SAT4-Rx to the fourth electrical connection terminal 3401, the fourth stub 3004 can act as the receiving antenna of the satellite positioning antenna 361, receiving RF signals in the aforementioned fourth satellite operating frequency band.

[0179] In other embodiments of this application, the following continues... Figure 30 As shown, the antenna structure 31 may further include a second ground network communication antenna 371, which may include the fourth branch 3004. In this case, the second ground network communication antenna 371 may share the fourth branch 3004 with the satellite positioning antenna 361 and the third satellite communication antenna 351. Furthermore, the third sub-chip 3233 in the communication chip 32 also has a second ground network transmitter GN2-Tx. The second ground network transmitter GN2-Tx is used to transmit radio frequency signals in the second ground network operating frequency band. For example, the second ground network communication antenna 371 may be a WIFI antenna or a cellular antenna. The following example uses the second ground network communication antenna 371 as a WIFI antenna; for example, the second ground network operating frequency band may include the WIFI 2.4G band (2400 MHz to 2483.5 MHz).

[0180] In addition, continue as Figure 30 As shown, the third RF switch RFS3 is also coupled between the second ground network transmitter GN2-Tx and the fourth electrical connection terminal 3401. The third RF switch RFS3 is used to connect the third satellite transmitter SAT3-Tx, the third satellite receiver SAT3-Rx, the positioning satellite receiver SAT4-Rx, or the second ground network transmitter GN2-Tx, to the fourth electrical connection terminal 3401. Similarly, when the third sub-chip 3233 controls the third RF switch RFS3 to connect the second ground network transmitter GN2-Tx to the fourth electrical connection terminal 3401, the fourth stub 3004 can act as the transceiver antenna of the second ground network communication antenna 371 to transmit and receive signals in the aforementioned second ground network operating frequency band (e.g., 2400 MHz to 2483.5 MHz). The process by which the third radio frequency switch RFS3 controls the third satellite transmitter SAT3-Tx, the third satellite receiver SAT3-Rx, and the positioning satellite receiver SAT4-Rx to conduct with the fourth electrical connection terminal 3401 is as described above and will not be repeated here.

[0181] The above example illustrates how the fourth branch 3004 can be reused as a second ground network communication antenna 371, a satellite positioning antenna 361, and a third satellite communication antenna 351. In other embodiments of this application, the fourth branch 3004 can be reused as any two of the second ground network communication antenna 371, the satellite positioning antenna 361, and the third satellite communication antenna 351. Furthermore, Figure 30 This example illustrates how the third satellite transmitter SAT3-Tx, the third satellite receiver SAT3-Rx, the positioning satellite receiver SAT4-Rx, and the second ground network transmitter GN2-Tx can all be integrated into a single communication chip, such as the aforementioned third sub-chip 3233. In other embodiments of this application, the third satellite transmitter SAT3-Tx and the third satellite receiver SAT3-Rx can be housed in the same chip, while the third satellite receiver SAT3-Rx and the positioning satellite receiver SAT4-Rx can be housed in different chips.

[0182] In other embodiments of this application, the following continues... Figure 30 As shown, the antenna structure 31 may further include a third ground network communication antenna 381, which may include a fifth stub 3005 having a fifth electrical connection terminal 3501. This fifth stub 3005 may be spaced apart from the first stub 3001. For example, when electronic device 01 is... Figure 30 In the folding machine shown, the first branch 3001 and the fifth branch 3005 can be located on the first metal frame 101a and the second metal frame 101b, respectively. Furthermore, the fifth branch 3005 can also be located on the same metal frame as the second branch 3002, the third branch 3003, and the fourth branch 3004, for example, on the second metal frame 101b. Moreover, the fifth branch 3005 is spaced apart from the second branch 3002, the third branch 3003, and the fourth branch 3004.

[0183] Furthermore, the communication chip 32 also includes a third ground network transmitter GN3-Tx, which is used to transmit radio frequency signals in the third ground network operating frequency band. For example, the aforementioned third ground network communication antenna 381 can be a WIFI antenna or a cellular antenna. Taking the third ground network communication antenna 381 as a WIFI antenna as an example, the aforementioned third ground network operating frequency band can include the WIFI 5G frequency band (5150 / MHz to 5825 / MHz). Moreover, the third ground network transmitter GN3-Tx can be coupled to the fifth electrical connection terminal 3501 of the fifth stub 3005. In this way, the fifth stub 3005 can function as the third ground network communication antenna 381 for transmitting and receiving signals in the third ground network operating frequency band.

[0184] In some other embodiments of this application, an RF switch can be coupled to the fifth electrical connection terminal 3501 of the third ground network transmitter GN3-Tx and the fifth branch 3005 to select whether the third ground network communication antenna 381 is in operation as needed.

In this case, the electronic device 01 can integrate three satellite antennas: the first satellite communication antenna 311 and the second satellite communication antenna 341 used for voice calls and SMS sending / receiving, and the third satellite communication antenna 351 used for SMS sending / receiving. This allows at least three types of satellite communication antennas to be integrated within the limited space of the electronic device 01.

[0186] In this way, users can choose different satellite antennas for communication based on their different needs or their location, thereby improving the user experience. For example, such as... Figure 31 As shown, in the satellite communication interface, electronic device 01 can display multiple satellite antenna options. The user can select and activate at least one satellite antenna function via the touch button 50. Alternatively, the display interface of electronic device 01 can recommend usable satellite antennas based on the user's location. For example, displaying... Figure 31 The prompt box 51 shown allows users to choose whether to enable the recommended satellite communication function based on its contents. Specifically, the "Y" button in prompt box 51 indicates that the first satellite communication antenna is enabled, and the "N" button indicates that the first satellite communication antenna is disabled.

[0187] The following is Figure 30 Taking the antenna structure 31 shown as an example, the control process of the first satellite communication antenna 311, the second satellite communication antenna 341, and the third satellite communication antenna 351 will be illustrated. For example, the control process of the first satellite communication antenna 311 may include... Figure 32 S101 to S106 are shown.

[0188] S101, Receive operation instructions from the user interface.

[0189] For example, the operation command of S101 can be triggered by the user. Figure 31 The operation command or trigger generated by button 50 in the middle. Figure 31 The operation instructions for pressing the "Y" button in the prompt box 51 shown above are all used to instruct the user to turn on the first satellite communication antenna.

[0194] S104, the first sub-chip activates the first satellite communication mode.

[0195] Example, Figure 30 The first sub-chip 3211 can activate the first satellite communication mode based on the communication module issued by the AP in S102 and the result of the AP switching control switch permission in S103, so that the first satellite communication antenna 311 is in working state.

[0197] Example, Figure 33 The first sub-chip 3211 can send switching control commands to the first RF switch RFS1, the first gating switch S1, and the second RF switch RFS2. In this case, under the control of the control signal sent by the first sub-chip 3211, the first RF switch RFS1 can connect the first satellite transmitter SAT1-Tx or the first satellite receiver SAT1-Rx1 to the first gating switch S1. Under the control of the control signal sent by the first sub-chip 3211, the first gating switch S1 can connect the first RF switch RFS1 to the first electrical connection terminal 3101 of the first stub 3001, thereby enabling the first stub 3001 to function as the transceiver antenna of the first satellite communication antenna 311. Furthermore, under the control of the control signal sent by the first sub-chip 3211, the second RF switch RFS2 can connect the first satellite receiver SAT1-Rx2 to the second electrical connection terminal 3201 of the second stub 3002, enabling the second stub 3002 to function as the receiving antenna of the first satellite communication antenna 311.

[0198] In addition, continue as Figure 33As shown, the first satellite communication antenna 311 may further include a fifth stub 3005, a sixth stub 3006, and a seventh stub 3007 as parasitic antennas, and the parasitic stubs are coupled to a tuning switch assembly 40. The first sub-chip 3211 can send control commands to each tuning switch assembly 40 so that the parasitic stubs can serve as transceiver antennas of the first satellite communication antenna 311, thereby achieving the purpose of adjusting the antenna aperture of the first satellite communication antenna 311.

[0200] Example, Figure 33 The first satellite transmitter SAT1-Tx of the first sub-chip 3211 transmits radio frequency signals in the operating frequency band of the first satellite, thereby enabling the second branch 3002, the fifth branch 3005, the sixth branch 3006, the first branch 3001, and the seventh branch 3007 to radiate the radio frequency signals in the operating frequency band of the first satellite into space in the form of electromagnetic waves, thus realizing radio frequency signal transmission. Alternatively, the first branch 3001, the sixth branch 3006, and the seventh branch 3007 receive electromagnetic waves in space and transmit them to the first satellite receiver SAT1-Rx1 of the first sub-chip 3211. In addition, the second branch 3002 and the fifth branch 3005 receive electromagnetic waves in space and transmit them to the second satellite receiver SAT2-Rx2 to realize the reception of radio frequency signals in the operating frequency band of the first satellite.

Figure 32 The method shown can be obtained similarly. Among them, Figure 34 The second sub-chip 3222 can send switching control commands to the second RF switch RFS2 and the second gating switch S2. In this case, under the control of the control signal sent by the second sub-chip 3222, the second RF switch RFS2 can connect the second satellite transmitter SAT2-Tx or the second satellite first receiver SAT2-Rx1 to the second gating switch S2. Under the control of the control signal sent by the second sub-chip 3222, the second gating switch S2 can connect the second RF switch RFS2 to the second electrical connection terminal 3201 of the second stub 3002, so that the second stub 3002 can be used as the transceiver antenna of the second satellite communication antenna 341. In addition, under the control of the control signal sent by the second sub-chip 3222, the second RF switch RFS2 can connect the second satellite second receiver SAT2-Rx2 to the third electrical connection terminal 3301 of the third stub 3003, so that the third stub 3003 can be used as the receiving antenna of the second satellite communication antenna 341.

[0203] Example, Figure 34 The second satellite transmitter SAT2-Tx of the second sub-chip 3222 transmits radio frequency signals in the operating frequency band of the second satellite, thereby enabling the second branch 3002, fifth branch 3005, sixth branch 3006, first branch 3001, and seventh branch 3007 to radiate the radio frequency signals in the operating frequency band of the second satellite into space in the form of electromagnetic waves, thus realizing radio frequency signal transmission. Alternatively, the second branch 3002, fifth branch 3005, sixth branch 3006, first branch 3001, and seventh branch 3007 receive electromagnetic waves in space and transmit them to the first receiver SAT2-Rx1 of the second satellite of the second sub-chip 3222. In addition, the third branch 3003 and fourth branch 3004 receive electromagnetic waves in space and transmit them to the second receiver SAT2-Rx2 of the second satellite of the second sub-chip 3222 to realize the reception of radio frequency signals in the operating frequency band of the second satellite.
