Description

[0001] The present application claims priority to the Chinese Patent Application No. 202410571737.2, filed on May 7, 2024, and entitled "Folding Terminal Device", the content of which is incorporated herein by reference in its entirety. TECHNICAL FIELD

[0002] The present application relates to the technical field of antennas, and in particular to an antenna device and an electronic device. BACKGROUND

[0003] With the continuous development of communication technology, electronic devices are developing towards miniaturization, thinness and high screen ratio. Moreover, as the integration requirement of electronic devices is getting higher and higher, the number of internal components of electronic devices is getting more and more, thereby leading to smaller and smaller internal architecture space of electronic devices. In this way, the available space for antennas is further compressed, thereby affecting the performance of the antennas. On this basis, as users' demand for diversified communication functions is increasing, it is getting more and more difficult to realize diversified communication functions in limited architecture space. UTILITY MODEL CONTENT

[0004] The present application provides an antenna device and an electronic device for realizing diversified communication functions in limited architecture space.

[0005] To achieve the above-mentioned purpose, the present application adopts the following technical solutions:

[0006] In an aspect of the present application, an antenna device is provided, which comprises a floor, 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 between the floor and the antenna structure, wherein the antenna structure comprises a first satellite communication antenna and a first ground net communication antenna. The first satellite communication antenna comprises a first branch, and the first branch has a first electrical connection end. The first ground net communication antenna comprises a first branch. The communication chip has a first satellite sending end and a first ground net sending end. The first satellite sending end is used for sending radio frequency signals of a first satellite operating frequency band, and the first ground net sending end is used for sending radio frequency signals of a first ground net operating frequency band. The first power amplifier is coupled with the first satellite sending end, and the second power amplifier is coupled with the first ground net sending end. The efficiency of the first power amplifier and the second power amplifier is different. The first gating switch is coupled between the first power amplifier and the first electrical connection end. The first gating switch is also coupled between the second power amplifier and the first electrical connection end. The first gating switch is located in the clearance. The first gating switch is used for connecting the first satellite sending end or the first ground net sending end with the first electrical connection end.

[0007] In summary, the antenna device provided by the embodiment of the present application comprises an antenna structure, and the communication chip in the antenna structure can have different signal sending ends, for example, a first satellite sending end and a first ground net sending end. In this case, the communication chip can send radio frequency signals of a first satellite operating frequency band through the first satellite sending end and send radio frequency signals of a first ground net operating frequency band through the first ground net sending end. In this way, the communication chip can have the function of sending radio frequency signals of two different operating frequency bands. Therefore, two independent chips for sending radio frequency signals of different operating frequency bands are not needed, so that the communication chip can have a smaller size compared with the two independent chips, and the space utilization of the antenna device is improved. On this basis, in order to meet the system energy loss requirement, the power amplification efficiency of the radio frequency signals emitted by the different signal sending ends of the communication chip, for example, the first satellite sending end and the first ground net sending end, can be different. In this case, compared with the scheme in which the first satellite sending end and the first ground net sending end share the same power amplifier, in the embodiment of the present application, the first satellite sending end and the first ground net sending end can be connected with a first power amplifier and a second power amplifier having different efficiencies respectively, so that the first power amplifier and the second power amplifier can both work in the state of the highest efficiency, thereby the input power of the first power amplifier and the second power amplifier can be reduced to meet the system energy loss requirement.

[0008] In addition, in order to further improve the space utilization of the antenna device, the first satellite communication antenna and the first ground network communication antenna both include the same branch, i.e., the first branch. The first branch has a first electrical connection end. In order to enable one of the first satellite communication antenna and the first ground network communication antenna to work alone at one time, the communication chip can send a control signal to the first gating switch to control the first gating switch to connect the first satellite sending end and the first electrical connection end. Thus, the first satellite sending end, the first power amplifier, the first gating switch, and the first electrical connection end can form a communication link of the first satellite communication antenna for data to be sent, so that the radio frequency signal of the first satellite working frequency band sent by the first satellite sending end is transmitted to the first electrical connection end to feed the first branch, so that the first branch can send the radio frequency signal of the first satellite working frequency band as the first satellite communication antenna. Alternatively, the communication chip can send a control signal to the first gating switch to control the first gating switch to connect the first ground network sending end and the first electrical connection end. Thus, the first ground network sending end, the second power amplifier, the first gating switch, and the first electrical connection end can form a communication link of the first ground network communication antenna for data to be sent, so that the radio frequency signal of the first ground network working frequency band sent by the first ground network sending end is transmitted to the first electrical connection end to feed the first branch, so that the first branch can send the radio frequency signal of the first ground network working frequency band as the first ground network communication antenna.

[0009] Based on this, the first satellite communication antenna and the first ground network communication antenna can share the same branch (i.e., the first branch), and the feeding ends are both the first electrical connection end of the first branch. In this way, it is not necessary to separately provide different branches and different feeding ends for the first satellite communication antenna and the first ground network communication antenna, so that the number of branches and the number of feeding ends in the antenna device can be simplified, the internal space of the electronic device with the antenna device is saved, the space utilization of the antenna device is improved, and the diversification of the communication function is realized in the limited architecture space. Therefore, the antenna device provided by the embodiments of the present application can improve the space utilization of the antenna device on the basis of meeting the system energy loss requirement. In addition, the first gating switch located in the clearance area has different conduction states, so that the first satellite communication antenna or the first ground network communication antenna cannot be in the working state at the same time. For example, when the first gating switch connects the first satellite sending end and the first electrical connection end, the first satellite communication antenna is in the working state. At this time, the first ground network communication antenna is in the non-working state. Similarly, when the first gating switch connects the first ground network sending end and the first electrical connection end, the first ground network communication antenna is in the working state. At this time, the first satellite communication antenna is in the non-working state. In this way, the probability of mutual interference between the communication link of the first ground network communication antenna for data to be sent and the communication link of the first ground network communication antenna for data to be sent can be reduced, and the signal loss is reduced.

[0010] In an alternative embodiment, the communication chip further comprises a first satellite first receiving end for receiving radio frequency signals of the first satellite operating frequency band. The antenna device further comprises a first radio frequency switch coupled between the first satellite transmitting end and the first gating switch, and coupled between the first satellite first receiving end and the first gating switch. The first radio frequency switch is configured to connect the first satellite transmitting end or the first satellite first receiving end 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 transmitting end to the first gating switch, so that the communication link of the first satellite communication antenna for transmitting data 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 end, the radio frequency signals of the first satellite operating frequency band transmitted by the first satellite transmitting end can be transmitted to the first electrical connection end through the above-mentioned communication link for transmitting data, so as to feed the first branch, so that the first branch can transmit the radio frequency signals of the above-mentioned first satellite operating frequency band as the first satellite communication antenna. Alternatively, the communication chip sends a control signal to the first radio frequency switch to control the first radio frequency switch to connect the first satellite first receiving end to the first gating switch, so that the communication link of the first satellite communication antenna for receiving data 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 end, the first branch can receive the radio frequency signals of the first satellite operating frequency band as at least part of the first satellite communication antenna, and transmit the radio frequency signals of the first satellite operating frequency band to the first satellite first receiving end through the above-mentioned communication link for receiving data, for data processing by the communication chip. In addition, when the first gating switch selects the first branch as at least part of the first ground network communication antenna to transmit and receive signals, the signal path between the first branch and the first ground network transmitting end does not need to be provided with the above-mentioned radio frequency switch, so as to reduce the signal loss in the 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 an alternative embodiment, the antenna device further comprises a first radio frequency test seat and a second radio frequency test seat. The first radio frequency test seat is coupled between the first gating switch and the first satellite transmitting end. The first radio frequency test seat can be connected to a test instrument to test and adjust the relevant parameters of the impedance matching of the communication link of the first satellite communication antenna. The second radio frequency test seat is coupled between the first gating switch and the first ground network transmitting end. The second radio frequency test seat can be connected to a test instrument to test and adjust the relevant parameters of the impedance matching of the communication link of the first ground network communication antenna.

[0012] In an alternative embodiment, the antenna device further comprises a first impedance matching network. The first impedance matching network is coupled between the first or second RF test socket and the first gating switch, or a first part of the first impedance matching network is coupled between the first or second RF test socket and the first gating switch, and a second part of the first impedance matching network is coupled between the first gating switch and the first electrical connection. The first impedance matching network can match the impedance of the communication link of the first satellite communication antenna or the first ground communication antenna. In this way, when the first gating switch is turned on between the first electrical connection and the first RF switch, the first gating switch is turned off between the first electrical connection and the first ground transmitter, so that the signal from the first ground transmitter does not affect the communication link of the first satellite communication antenna, and 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, so as to improve the radiation power of the first satellite communication antenna and reduce signal loss. Alternatively, when the first gating switch is turned on between the first electrical connection and the first ground transmitter, the first gating switch is turned off between the first electrical connection and the first satellite transmitter, so that the signal from the first satellite transmitter does not affect the communication link of the first ground communication antenna, and the impedance matching effect of the communication link of the first ground communication antenna matches the structure and related parameters of the first impedance matching network, so as to improve the radiation power of the first ground communication antenna and reduce signal loss.

[0013] In an alternative embodiment, the antenna device further comprises a first impedance matching network, which is coupled between the first gating switch and the first electrical connection. The technical effect of the first impedance matching network is as described above, and will not be repeated here.

[0014] In an alternative embodiment, the first satellite communication antenna further comprises a second branch, which is spaced apart from the first branch. The second branch has a second electrical connection. The communication chip further has a first satellite second receiving end. The first satellite second receiving end is used to receive a radio frequency signal of the first satellite operating frequency band. The first satellite second receiving end is coupled to the second electrical connection. In this case, when the first satellite communication antenna transmits a radio frequency signal of the first satellite operating frequency band, the first branch is in a working state to transmit a radio frequency signal of the first satellite operating frequency band. When the first satellite communication antenna receives a radio frequency signal of the first satellite operating frequency band, the first branch and the second branch can be in a working state at the same time to receive a radio frequency signal of the first satellite operating frequency band. In this way, the width and gain of the receiving beam of the first satellite communication antenna can be expanded, so that the electronic device is more easily realized to have a satellite function.

[0015] In an alternative embodiment, the antenna structure further comprises a second satellite communication antenna, the second satellite communication antenna comprising a second branch. The communication chip has a second satellite transmitting end and a second satellite first receiving end. The second satellite transmitting end is configured to transmit radio frequency signals in a second satellite operating frequency band, and the second satellite first receiving end is configured to receive radio frequency signals in the second satellite operating frequency band. In addition, the antenna device further comprises a second radio frequency switch, which is coupled between the first satellite second receiving end and the 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 also coupled between the second satellite first receiving end and the second electrical connection end. The second radio frequency switch is configured to connect the first satellite second receiving end, the second satellite transmitting end or the second satellite first receiving end to the second electrical connection end. In an 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 in a limited space. The user can select the above two satellites according to needs or the electronic device can select the above two satellites according to the region where the user is located, thereby realizing the diversification of communication functions.

[0016] In an alternative embodiment, the antenna device further comprises a second gating switch, a third radio frequency test seat and a second impedance matching network. The second gating switch is coupled between the second radio frequency switch and the second electrical connection end, and the second gating switch is located in the clearance area. The third radio frequency test seat is coupled between the second gating switch and the second radio frequency switch. At least part of the second impedance matching network can be coupled between the second gating switch and the second electrical connection end; or at least part of the second impedance matching network is coupled to one side of the second gating switch away from the second electrical connection end, for example, the second impedance matching network is coupled between the second gating switch and the third radio frequency test seat. Or, for another example, a first part of the second impedance matching network is coupled between the second gating switch and the second electrical connection end, and a second part of the second impedance matching network is coupled between the second gating switch and the third radio frequency test seat. When the first gating switch connects the first ground network transmitting end to the first electrical connection end, the second gating switch is configured to disconnect at least part of the second impedance matching network from the second electrical connection end. The second impedance matching network can match the impedance of the communication link of the second satellite communication antenna. The third radio frequency test seat can be connected to a test instrument to test and adjust the relevant parameters of the impedance matching 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 transmits and receives radio frequency signals in the first ground network operating frequency band, in order to avoid the second impedance matching network affecting the signals on the second branch which is a parasitic antenna of the first ground network communication antenna, the second gating switch can disconnect at least part of the second impedance matching network from the second electrical connection end of the second branch, thereby achieving the purpose of improving the aperture and gain of the first ground network communication antenna.

When the second satellite communication antenna receives radio frequency signals of the second satellite operating frequency band, the second branch and the third branch are simultaneously in a working state to receive radio frequency signals of the second satellite operating frequency band. In this way, the width and gain of the receiving beam of the second satellite communication antenna can be expanded, so that the electronic device is more likely to realize the pointing function.

[0075] Hereinafter, the terms "first", "second", and the like are used only for description convenience, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined with "first", "second", and the like can explicitly or implicitly include one or more of the features.

[0077] The symmetry (for example, axial symmetry, or central symmetry, etc.), parallel, vertical, orthogonal, identical (for example, the same length, the same width, etc.) and the like mentioned in the embodiments of the present application are all relative to the current process level, and not the absolute definition in the mathematical sense. There can be a predetermined angle deviation between two components that are parallel or vertical to each other. In an embodiment, the predetermined angle can be an angle within ±10°, for example, the predetermined angle deviation is ±5°.

[0078] In the present application, unless otherwise explicitly specified and limited, the term "connection" should be understood broadly, for example, the "connection" can be a fixed mechanical connection, or a detachable mechanical connection, or integrated; or the "connection" can be direct connection, or indirect connection through an intermediate medium.

[0079] In addition, unless otherwise explicitly specified and limited, the term "coupling" should be understood broadly, for example, the "coupling" can be direct electrical connection, for example, physical contact and electrical conduction between two components, or can be understood as electrical connection between different components through the entity circuit of the copper foil or wire of the printed circuit board (PCB) that can transmit electrical signals in the circuit configuration, to transmit electrical signals; or the "coupling" can be indirect electrical connection between two components through an intermediate medium; or the "coupling" can be electrical connection between two components through the way of space / without contact, for example, electrical connection between two components through capacitive coupling to transmit electrical signals.

[0080] It should be noted that in the drawings of the embodiments of the present application, the components are represented by arrows; and the components are represented only by arrows.

[0081] Embodiments of the present application provide an electronic device which can be applied to various communication systems or communication protocols, such as global system of mobile communication (GSM), code division multiple access (CDMA) system, wideband code division multiple access wireless (WCDMA), general packet radio service (GPRS), long term evolution (LTE), etc. The electronic device can have a display function, and can include a mobile phone, a pad, a television, a smart wearable product (e.g., a smart watch, a smart bracelet), a virtual reality (VR) electronic device, an augmented reality (AR) electronic device, a positioning device, etc. Embodiments of the present application do not specially limit the specific form of the electronic device.

[0082] In some embodiments of the present application, the electronic device can have a display function. For example, the electronic device 01 can be a bar phone as shown in FIG. 1, which can include a housing 10 and a display screen 20 connected to the housing 10. For example, the display screen 20 can be a self-luminous 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, the display screen 20 can also be a liquid crystal display (LCD) which needs a backlight source. Figure 1

[0083] For the convenience of description, XYZ coordinate axes are established in the accompanying drawings, wherein the XY surface formed by the X direction and the Y direction can be parallel to the display surface (the surface for displaying images) of the display screen 20. The Z direction can be perpendicular to the display surface of the display screen 20, i.e., the Z direction can be the stacking direction of the housing 10 and the display screen 20. In some embodiments of the present application, the housing 10 can include a metal frame 101 arranged around the display screen 20 and a bottom plate (not shown in FIG. 1) located at the back of the display screen 20. Figure 1 ​​

[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 is shown. The antenna device 30 can include an antenna structure 31, a communication chip 32, and a first gating switch S1. The antenna structure 31 can include a plurality of antennas, which are devices for receiving (Rx) or transmitting (Tx) electromagnetic wave radiation. In some cases, "antenna" is understood in a narrow sense as a radiator, which changes 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 through the feeder line, and is converted into electromagnetic wave energy of a certain polarization through the radiator and radiated in the desired direction. The receiving radiator converts electromagnetic wave energy of a certain polarization from a certain direction in space into modulated high-frequency current energy, which is delivered to the input of the receiver through the feeder line.

[0089] In some embodiments of the present application, it is continued as Figure 3 As shown, the antenna structure 31 can include a first satellite communication antenna 311 and a first ground net communication antenna 312. Among them, the first satellite communication antenna 311 can be used to receive or transmit radio frequency signals of the first satellite operating frequency band. For example, the first satellite communication antenna 311 can be a high-orbit satellite communication antenna, for example, the orbit height can be around 35786 kilometers. At this time, in the case of using the first satellite communication antenna 311 for voice communication, transmitting and receiving short messages (or short messages) or transmitting low-speed data, the above-mentioned first satellite operating frequency band can include the uplink frequency band (for example, 1980 / MHz~2010 / MHz) and the downlink frequency band (for example, 2170 / MHz~2200 / MHz).

[0090] Or, for example, in the case of the first satellite communication antenna 311 being the above-mentioned high-orbit satellite communication antenna, the first satellite communication antenna 311 can also be used only for short message transmission and reception. In this case, the above-mentioned first satellite operating frequency band can include the uplink frequency band (for example, 1610 / MHz~1626 / MHz) and the downlink frequency band (for example, 2483 / MHz~2500 / MHz). Or, for example, the above-mentioned first satellite communication antenna 311 can also be a low-orbit satellite communication antenna, and the orbit height can be between 500~2000 kilometers, for example, 1175 kilometers. At this time, in the case of using the first satellite communication antenna 311 for voice communication, transmitting and receiving short messages or transmitting low-speed data, the above-mentioned first satellite operating frequency band can include the uplink frequency band (for example, 1668 / MHz~1675 / MHz) and the downlink frequency band (for example, 1518 / MHz~1525 / MHz).

[0091] In addition, Figure 3The first ground network communication antenna 312 shown is used to receive or transmit radio frequency signals of a 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. The cellular communication frequency band can include a middle high band (MHB), for example, 1800 / MHz-2700 / MHz, and a 5G new radio (NR) frequency 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, for example, a WIFI 2.4G frequency band (2400 / MHz-2483.5 / MHz) or a WIFI 5G frequency band (5150 / MHz-5825 / MHz).

[0092] For the convenience of description below, the first satellite communication antenna 311 is taken as a high-orbit antenna, the first satellite communication antenna 311 is used for voice calls, sending and receiving short messages (or short messages), or transmitting low-speed data, and the first satellite operating frequency band can include an uplink frequency band (for example, 1980 / MHz-2010 / MHz) and a downlink frequency band (for example, 2170 / MHz-2200 / MHz); 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.

[0093] In addition, as shown, Figure 3 The first satellite communication antenna 311 can include a first branch 3001 having a first electrical connection end 3101. The first ground network communication antenna 312 can include the first branch 3001. Therefore, the first satellite communication antenna 311 and the first ground network communication antenna 312 both include the first branch 3001, so the first satellite communication antenna 311 and the first ground network communication antenna 312 can share the first branch 3001.

[0094] On this basis, as shown, Figure 3 The communication chip 32 can have a first satellite transmission end SAT1-Tx and a first ground network transmission end GN1-Tx. The first satellite transmission end SAT1-Tx can be used to transmit radio frequency signals of a first satellite operating frequency band (for example, an uplink frequency band 1980 / MHz-2010 / MHz). The first ground network transmission end GN1-Tx is used to transmit radio frequency signals of a first ground network operating frequency band (for example, a cellular communication frequency band). For example, in the case where the first ground network operating frequency band is a cellular communication frequency band, the first ground network transmission end GN1-Tx can also share the first ground network receiving end GN1-Rx to transmit serial cellular transmission or reception signals.

[0095] The communication chip 32 may, for example, include a baseband chip, or the communication chip 32 may include a part of a radio frequency (RF) chip in addition to the baseband chip. The baseband chip can process a digital signal, i.e., a low-frequency part of a signal. For example, the baseband chip can include a digital signal processor (DSP), a modem, a codec, and the like. The baseband can implement functions of processing, modulation / demodulation, channel coding / decoding, and the like of a digital signal. In addition, the RF chip can process a radio frequency signal, i.e., a high-frequency part of a signal. The RF chip can include a radio frequency amplifier, a mixer, a filter, a frequency synthesizer, and the like. The RF chip is used to generate, amplify, modulate, and demodulate a radio frequency signal. The baseband chip and the RF chip can be provided with a digital-to-analog converter for converting a digital signal and an analog signal.

[0096] Further, as shown in Figure 3 The first switch S1 is coupled between the first satellite transmitting end SAT1-Tx and the first electrical connection end 3101. Also, the first switch S1 is coupled between the first ground net transmitting end GN1-Tx and the first electrical connection end 3101. The first switch S1 can be used to connect the first satellite transmitting end SAT1-Tx or the first ground net transmitting end GN1-Tx with the first electrical connection end 3101. For example, the first switch S1 can be a single pole multi throw (SPMT) switch, such as a single pole four throw (SP4T) switch. Alternatively, the first switch S1 can be a combination of multiple (e.g., 4) single pole single throw (SPST) switches, which is not limited in the present application.

[0097] In some embodiments of the present application, the antenna device 30 can further include a first power amplifier (PA) 331, a second power amplifier 332, as shown in Figure 3 The first power amplifier 331 is coupled with the first satellite transmitting end SAT1-Tx, and the first switch S1 is coupled between the first power amplifier 331 and the first electrical connection end 3101. In this case, the first satellite transmitting end SAT1-Tx can be coupled with the first electrical connection end 3101 through the first power amplifier 331 and the first switch S1. The first power amplifier 331 can perform power amplification on the signal from the first satellite transmitting end SAT1-Tx.

[0098] In addition, the second power amplifier 332 is coupled with the first ground network transmitting end GN1-Tx, and the first gating switch S1 is further coupled between the second power amplifier 332 and the first electrical connection end 3101. In this case, the first ground network transmitting end GN1-Tx can be coupled with the first electrical connection end 3101 through the second power amplifier 332 and the first gating switch S1. The second power amplifier 332 can perform power amplification on the signal from the first ground network transmitting end GN1-Tx. For example, the first power amplifier 331 and the second power amplifier 332 can belong to a part of the above-mentioned 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 the present application.

[0099] The efficiencies of the first power amplifier 331 and the second power amplifier 332 are different. The efficiency of the power amplifier can be the ratio of the output power to the input power of the power amplifier, and the efficiency of the power amplifier can be used to measure the energy conversion rate from the power supply to the load. The higher the efficiency of the power amplifier, the smaller the input power of the power amplifier while meeting the output power requirement, that is, the smaller the energy loss from the power supply to the load, and vice versa.

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

[0101] In this way, by coupling the first satellite transmitting end SAT1-Tx (used for transmitting radio frequency signals of the first satellite operating frequency band) and the first ground network transmitting end GN1-Tx (used for transmitting the first ground network operating frequency band) with the first power amplifier 331 and the second power amplifier 332 having different efficiencies respectively, the first power amplifier 331 and the second power amplifier 332 can both work in the state of the highest efficiency, so as to reduce the input power of the first power amplifier 331 and the second power amplifier 332 respectively while meeting the output power requirement of the first power amplifier 331 and the second power amplifier 332, thereby achieving the purpose of reducing energy loss. The above is an example of the efficiency of the first power amplifier 331 being greater than that of the second power amplifier 332. In other embodiments, the efficiency of the first power amplifier 331 can be less than that of the second power amplifier 332.

[0102] On this basis, the antenna device 30 has a clearance area 300 as shown in Figure 3 or Figure 4 The first gating switch S1 can be located in the clearance area 300. The clearance area 300 can be an area where a gap between the ground plane GND of the electronic device and the antenna structure 31 is located. The following illustrates the setting mode of the clearance area 300.

[0103] In some embodiments, the electronic device can include a printed circuit board (PCB), and the first gating switch S1, the first power amplifier 331, the second power amplifier 332 and the communication chip 32 can be disposed on the PCB and electrically connected to the PCB. A metal layer of the PCB can serve as the ground plane GND. The ground plane GND can be rectangular as shown in Figure 3 or the ground plane GND can also have a hollow structure, such as an L-shaped structure as shown in Figure 4 or a U-shaped structure or other shapes. The hollow part of the ground plane GND can be filled with a dielectric layer of the PCB, so that the position of the dielectric layer can support the first gating switch S1.

[0104] In summary, the antenna device 30 provided by the embodiments of the present application includes an antenna structure 31 as shown in Figure 3 The communication chip 32 in the antenna structure 31 can have different signal sending ends, such as a first satellite sending end SAT1-Tx and a first ground network sending end GN1-Tx. In this case, the communication chip 32 can send radio frequency signals of the first satellite operating frequency band (for example, the uplink frequency band 1980 / MHz-2010 / MHz) through the first satellite sending end SAT1-Tx, and can also send radio frequency signals of the first ground network operating frequency band (for example, a cellular communication frequency band) through the first ground network sending end GN1-Tx. In this way, the communication chip 32 can have the function of sending radio frequency signals of two different operating frequency bands. Therefore, it is not necessary to set two independent chips for sending radio frequency signals of different operating frequency bands, so that the communication chip 32 can have a smaller size compared with the two independent chips, which is beneficial to improve the space utilization of the antenna device 30.

[0105] On this basis, continue as Figure 3As shown, in order to meet the requirement of system energy loss, the efficiency of power amplification required by the radio frequency signals respectively emitted by different signal transmitting ends of the communication chip 32, such as the first satellite transmitting end SAT1-Tx and the first ground network transmitting end GN1-Tx, can be different. In this case, compared with the scheme in which the first satellite transmitting end SAT1-Tx and the first ground network transmitting end GN1-Tx share the same power amplifier, in the embodiment of the present application, the first satellite transmitting end SAT1-Tx and the first ground network transmitting end GN1-Tx can be respectively connected to the first power amplifier 331 and the second power amplifier 332 with different efficiencies, so that the first power amplifier 331 and the second power amplifier 332 can both work in the state of the highest efficiency, thereby being able to reduce the input power of the first power amplifier 331 and the second power amplifier 332 respectively while meeting the output power requirement of the first power amplifier 331 and the second power amplifier 332, so as to meet the requirement of system energy loss.

[0106] In addition, in order to further improve the space utilization of the antenna device 30, it is continued that Figure 3 As shown, the first satellite communication antenna 311 and the first ground network communication antenna 312 both include the same branch, i.e., the first branch 3001. The first branch 3001 has a first electrical connection end 3101. In order to enable one of the first satellite communication antenna 311 and the first ground network communication antenna 312 sharing the same branch to work alone at one time, the communication chip 32 can send a control signal to the first gating switch S1 to control the first gating switch S1 to turn on the first satellite transmitting end SAT1-Tx and the first electrical connection end 3101. Therefore, the first satellite transmitting end SAT1-Tx, the first power amplifier 331, the first gating switch S1 and the first electrical connection end 3101 can form a communication link of the data to be transmitted by the first satellite communication antenna 311, so that the radio frequency signal of the first satellite operating frequency band (for example, the uplink frequency band 1980 / MHz~2010 / MHz) transmitted by the first satellite transmitting end SAT1-Tx is transmitted to the first electrical connection end 3101 after the power amplification of the first power amplifier 331, so as to feed the first branch 3001, and further enable the first branch 3001 to transmit the radio frequency signal of the above-mentioned first satellite operating frequency band as the first satellite communication antenna 311.

[0107] Alternatively, it is continued that 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 turn on the first ground network sending end GN1-Tx and the first electrical connection end 3101. Therefore, the first ground network sending end GN1-Tx, the second power amplifier 332, the first gating switch S1, and the first electrical connection end 3101 can form a communication link of the to-be-sent data of the first ground network communication antenna 312, so that the radio frequency signal of the first ground network operating frequency band (for example, a cellular communication frequency band) sent by the first ground network sending end GN1-Tx is transmitted to the first electrical connection end 3101 after the power amplification of the second power amplifier 332, to feed the first branch 3001, so that the first branch 3001 can send the radio frequency signal of the above-mentioned first ground network operating frequency band as the first ground network communication antenna 312.

[0108] Based on this, the first satellite communication antenna 311 and the first ground network communication antenna 312 can share the same branch (that is, the first branch 3001), and the feeding ends are the first electrical connection end 3101 of the first branch 3001. In this way, it is not necessary to separately set different branches and different feeding ends for the first satellite communication antenna 311 and the first ground network communication antenna 312, thereby being able to simplify the number of branches and the number of feeding ends in the antenna device 30, achieve the purpose of saving the internal space of the electronic device with the antenna device 30, and improve the space utilization rate of the antenna device 30, so as to realize the diversification of communication functions in a limited architecture space. As known from the above, the antenna device 30 provided by the embodiment of the application can improve the space utilization rate of the antenna device 30 on the basis of meeting the system energy loss requirement.

[0109] In addition, the first gating switch S1 located in the clearance area 300 has different conduction states, which can make the first satellite communication antenna 311 or the first ground network communication antenna 312 not in the working state (for example, the state of transmitting signals) at the same time. For example, when the first gating switch S1 turns on the first power amplifier 331 and the first electrical connection end 3101, the first satellite communication antenna 311 is in the working state. At this time, the second power amplifier 332 and the first electrical connection end 3101 are in the disconnected state, and the first ground network communication antenna 312 is in the non-working state. Similarly, when the first gating switch S1 turns on the second power amplifier 332 and the first electrical connection end 3101, the first ground network communication antenna 312 is in the working state. At this time, the first satellite communication antenna 311 is in the non-working state. In this way, the probability of mutual interference between the communication link of the to-be-sent data of the first ground network communication antenna 312 and the communication link of the to-be-sent data of the first ground network communication antenna 312 can be reduced, achieving the purpose of reducing signal loss.

[0110] In some embodiments of the present application, the "electrically connected end" can be a section of the radiating body on the antenna branch. The above-mentioned "end" cannot be understood in a narrow sense as an end point or end portion physically disconnected from other antenna branches, but can also be considered as a certain point or section on the continuous antenna branch. In an embodiment, the "end" can include a coupling area on the branch that couples other conductive structures. For example, when the antenna branch serves as a main feed radiating body, the electrically connected end can be referred to as a feed end when it is coupled to the feed circuit. Alternatively, when the above-mentioned antenna branch serves as a parasitic branch, the above-mentioned antenna branch can be capacitively or inductively grounded, and the electrically connected end can also be referred to as a ground end.

[0111] In addition, as shown in Figure 3 The antenna device 30 can further include a tuning switch assembly 40 coupled to the electrically connected end 3101. The tuning switch assembly 40 can include a tuning device and a switch coupled to the tuning device. The tuning device can include at least one of a capacitor and an inductor. By controlling the switch to select different tuning devices to be coupled to the electrically connected end 3101, the antenna aperture of the first branch 3001 can be adjusted as needed. The structure of the tuning switch assembly 40 is not limited in the embodiments of the present application.

[0112] In the embodiments of the present application, the capacitor can be understood as a lumped capacitor and / or a distributed capacitor. The lumped capacitor refers to a component that exhibits capacitance, such as a capacitor element; the distributed capacitor (or distributed capacitor) refers to an equivalent capacitor formed by two conductive parts spaced apart by a certain gap. The inductor can be understood as a lumped inductor and / or a distributed inductor. The lumped inductor refers to a component that exhibits inductance, such as an inductor element; the distributed inductor (or distributed inductor) refers to an equivalent inductor formed by a conductive part of a certain length, such as an equivalent inductor formed by a conductor due to curling or rotation.

[0113] As shown in Figure 4 In some embodiments of the present application, the communication chip 32 can include a first satellite communication chip 321 and a first ground network communication chip 322. The first satellite communication chip 321 can have the first satellite transmission end SAT1-Tx, and the first ground network communication chip 322 can have the first ground network transmission end GN1-Tx. For example, the first satellite communication chip 321 and the first ground network communication chip 322 can be independent packaged chips. Alternatively, for another example, the first satellite communication chip 321 and the first ground network communication chip 322 can be independent die chips packaged in the same chip package, and the present application does not limit this.

[0114] Based on this, in order to improve the space utilization of the electronic device, when the electronic device 01 is a straight machine as shown in Figure 5 The metal frame 101 in the shell of the electronic device 01 can include the antenna structure 31 (such asFigure 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 direction of the first branch 3001 is upward, and the communication link of the to-be-sent data is transmitted to the first electrical connection end 3101 to feed the first branch 3001, so that the first branch 3001 can send the radio frequency signal of the first satellite operating frequency band as the first satellite communication antenna 311.

[0121] Alternatively, as shown in Figure 7 , 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 turn on the LNA and the first gating switch S1, so that the communication link of the to-be-received data of the first satellite communication antenna 311 (including the first satellite first receiving end SAT1-Rx1, the LNA and the first radio frequency switch RFS1) is in communication with 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 turn on the first radio frequency switch RFS1 and the first electrical connection end 3101, the first branch 3001 can receive the radio frequency signal of the first satellite operating frequency band as at least part of the first satellite communication antenna 311, and the dotted arrow in the direction of Figure 7 downward in the first branch 3001 is transmitted to the first satellite first receiving end SAT1-Rx1 through the communication link of the to-be-received data for data processing by the communication chip 32.

[0122] As can be seen from the above, as shown in Figure 7 , the communication chip 32 can select the first branch 3001 as at least part of the first satellite communication antenna 311 or as at least part of the first ground network communication antenna 312 to transmit and receive signals by controlling different paths in the first gating switch S1. In addition, when the first electrical connection end 3101 and the first radio frequency switch RFS1 are turned on in the first gating switch S1, the communication chip 32 can select the first branch 3001 as at least part of the first satellite communication antenna 311 to transmit the radio frequency signal of the first satellite operating frequency band or as at least part of the first satellite communication antenna 311 to receive the radio frequency signal of the first satellite operating frequency band by controlling different paths in the first radio frequency switch RFS1.

[0123] For example, the first radio frequency switch RFS1 can be an SPMT (for example, SP4T) or a combination of multiple (for example, 4) SPST switches, which is not limited in the present application. As a radio frequency switch, the performance indicators of the first radio frequency switch RFS1 can include insertion loss, isolation between channels, power tolerance under different reflection coefficients, etc. The first radio frequency switch RFS1 will generate a large signal loss. As can be seen from the above, Figure 7It can be known that when the first gating switch S1 selects the first branch 3001 as at least part of the first ground network communication antenna 312 to transmit and receive signals, no RF switch needs to be set in the signal path between the first branch 3001 and the first ground network transmitting end GN1-Tx, so that the signal loss in the path can be reduced. In addition, the performance indicators of the first gating switch S1 located in the clearance area 300 (as shown in Figure 3 The performance indicators of the first gating switch S1 located in the clearance area 300 (as shown in

[0124] In comparison, in the related art, as shown in Figure 8 Two different first antenna signals (for example, RF signals of the first satellite operating frequency band) and second antenna signals (for example, cellular signals) need to be selected and transmitted to the same radiator after being gated by the RF switch (SP4T). In this case, the communication link of the first antenna signal and the communication link of the second antenna signal both need to pass through the RF switch (SP4T), so that under the influence of the RF switch (SP4T), the signal loss of the above two antenna signals is large.

[0125] In addition, as shown in Figure 9 The antenna device 30 in the embodiment of the present application can further include a first impedance matching network 41, a first RF test seat (switch) 43, and a second RF test seat 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 seat 43 can be connected to a test instrument to test and adjust the related parameters of the impedance matching of the communication link of the first satellite communication antenna 311. For example, by using a return loss curve or a Smith chart, the related parameters and structure of the first impedance matching network 41 are adjusted to achieve the effect of impedance matching. Similarly, the second RF test seat 44 can be connected to a test instrument to test and adjust the related parameters of the impedance matching of the communication link of the first ground network communication antenna 312.

[0126] The impedance of an antenna is generally the ratio of the voltage to the current at the input terminals of the antenna. Antenna impedance is a measure of the resistance to electrical signals in an antenna. The main purpose of matching the impedance of an antenna is to achieve matching between the antenna and the transmission line. When the antenna and the transmission line are matched, the power transmitted from the transmitter to the antenna or from the antenna to the receiver is maximum, and no reflected wave occurs on the transmission line, the reflection coefficient is equal to zero, and the standing wave ratio is equal to 1. The degree of matching between the antenna and the transmission line is measured by the size of the reflection coefficient or the standing wave ratio at the input terminals of the antenna. For a transmitting antenna, if the matching is not good, the radiated power of the antenna will decrease, the loss on the transmission line will increase, the power capacity of the transmission line will decrease, and in severe cases, the frequency "pulling" phenomenon of the transmitter will occur, i.e., the oscillation frequency will change.

[0127] The following illustrates the setting mode of the first impedance matching network 41. In some embodiments of the present application, as shown in FIG. 4, the first RF test seat 43 can be coupled between the first gating switch S1 and the first satellite transmitting end SAT1-Tx. In the case that the antenna device 30 has the first RF switch RFS1 described above, the first RF test seat 43 can be coupled between the first gating switch S1 and the first RF switch RFS1. The second RF test seat 44 can be coupled between the first gating switch S1 and the first ground network transmitting end GN1-Tx. For example, in the case that the antenna device 30 includes the first power amplifier 331, the second RF test seat 44 can be coupled between the first gating switch S1 and the first power amplifier 331. In addition, as shown in FIG. 4, the first impedance matching network 41 can be coupled between the first gating switch S1 and at least one of the first RF test seat 43 or the second RF test seat 44. In this case, the first impedance matching network 41 can be coupled between the first RF test seat 43 and the first gating switch S1, or the first impedance matching network 41 can be coupled between the second RF test seat 44 and the first gating switch S1. Figure 9 Figure 9 The following illustrates the setting mode of the first impedance matching network 41. In some embodiments of the present application, as shown in FIG. 4, the first RF test seat 43 can be coupled between the first gating switch S1 and the first satellite transmitting end SAT1-Tx. In the case that the antenna device 30 has the first RF switch RFS1 described above, the first RF test seat 43 can be coupled between the first gating switch S1 and the first RF switch RFS1. The second RF test seat 44 can be coupled between the first gating switch S1 and the first ground network transmitting end GN1-Tx. For example, in the case that the antenna device 30 includes the first power amplifier 331, the second RF test seat 44 can be coupled between the first gating switch S1 and the first power amplifier 331. In addition, as shown in FIG. 4, the first impedance matching network 41 can be coupled between the first gating switch S1 and at least one of the first RF test seat 43 or the second RF test seat 44. In this case, the first impedance matching network 41 can be coupled between the first RF test seat 43 and the first gating switch S1, or the first impedance matching network 41 can be coupled between the second RF test seat 44 and the first gating switch S1. Figure 9

[0128] In this case, when the first gating switch S1 turns on the first electrical connection end 3101 and the first RF switch RFS1, the first gating switch S1 will disconnect the first electrical connection end 3101 and the first ground network transmitting end GN1-Tx, so that the signal from the first ground network transmitting end GN1-Tx will not affect the communication link of the first satellite communication antenna 311 (including the first satellite transmitting end SAT1-Tx, the first power amplifier 331, the first RF switch RFS1, the first impedance matching network 41, the first gating switch S1, and the first electrical connection end 3101), so that the impedance matching effect of the communication link of the first satellite communication antenna 311 matches the structure and related parameters of the first impedance matching network 41, thereby improving the radiated power of the first satellite communication antenna 311 and reducing signal loss. ​​

[0129] Similarly, when the first gating switch S1 turns on the first electrical connection end 3101 and the first ground network transmitting end GN1-Tx, the first gating switch S1 will turn off the first electrical connection end 3101 and the first satellite transmitting end SAT1-Tx, so that the signal from the first satellite transmitting end SAT1-Tx will not affect the communication link of the first ground network communication antenna 312 (including the first ground network transmitting end GN1-Tx, the second power amplifier 332, the first impedance matching network 41, the first gating switch S1, and the first electrical connection end 3101), thereby matching the impedance matching effect of the communication link of the first ground network communication antenna 312 with the structure and related parameters of the first impedance matching network 41, achieving the purpose of improving the radiation power of the first ground network communication antenna 312 and reducing signal loss. In this way, by setting the above-mentioned first gating switch S1, the isolation between the communication link of the first satellite communication antenna 311 and the communication link of the first ground network communication antenna 312 can be improved, achieving the purpose of reducing signal loss.

[0130] The above is an example of the first impedance matching network 41 being coupled between at least one of the first radio frequency test seat 43 or the second radio frequency test seat 44 and the first gating switch S1. In other embodiments of the present application, as shown in Figure 10 The first impedance matching network 41 can include two parts, first part 41a and second part 41b. The first part 41a of the first impedance matching network can be coupled between at least one of the first radio frequency test seat 43 or the second radio frequency test seat 44 and the first gating switch S1, and the second part 41b of the first impedance matching network can be coupled between the first gating switch S1 and the first electrical connection end 3101. Alternatively, as shown in Figure 11 The first impedance matching network 41 is coupled between the first gating switch S1 and the first electrical connection end 3101. The technical effect of the first impedance matching network 41 and the first gating switch S1 is as described above, which will not be repeated here.

[0131] As described above, the communication chip 32 has a first satellite transmitting end SAT1-Tx and a first satellite first receiving end SAT1-Rx1 matched with the first satellite communication antenna 311. At this time, the first satellite communication antenna 311 can be an antenna with 1T1R function. Among them, 1T in 1T1R refers to one transmitting end (i.e., the first satellite transmitting end SAT1-Tx), and 1R refers to one receiving end (i.e., the first satellite first receiving end SAT1-Rx1).

[0132] In other embodiments of the present application, the above-mentioned first satellite communication antenna 311 can be an antenna with 1T2R function. For example, as shown in 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 with the scheme of arranging the first branch 3001 and the second branch 3002 on the same metal frame, by arranging the first branch 3001 and the second branch 3002 on different metal frames (for example, the first metal frame 101a and the second metal frame 101b described above), the first metal frame 101a and the second metal frame 101b can provide greater size to serve as the first branch 3001 and the second branch 3002 respectively, so as to increase the physical length of the first branch 3001 and the second branch 3002, and further achieve the purpose of improving the antenna aperture and gain.

[0139] In this case, as shown in Figure 14 , since a part of the top frame of the first metal frame 101a is reused as the first branch 3001, and a part of the top frame 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 rotation shaft 11, that is, the first branch 3001 and the second branch 3002 are arranged 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 can be seen from (b) in Figure 15 that the part with darker color of the antenna pattern, that is, the part with greater gain, covers the top frame of the first metal frame 101a. In addition, when the first satellite communication antenna 311 receives (Rx) the first satellite operating frequency band through the second branch 3002, it can be seen from (c) in Figure 15 that the part with darker color of the antenna pattern, that is, the part with greater gain, covers the top frame of the second metal frame 101b.

[0140] As shown in Figure 14 , the first branch 3001 and the second branch 3002 can be arranged symmetrically about the rotation shaft 11. In this way, when the first satellite communication antenna 311 transmits (Tx) the first satellite operating frequency band, the pattern as shown in (a) in Figure 15 is similar to the pattern as shown in (b) in Figure 15 and (c) in Figure 15 when the first satellite communication antenna 311 receives (Rx) the first satellite operating frequency band, the antenna pattern has omnidirectional property, achieving better circular polarization coverage, larger coverage range, and the gain distribution (that is, the color depth) of the above-mentioned patterns is more consistent. This can indicate that the first satellite communication antenna 311 has consistent radiation performance when transmitting or receiving the first satellite operating frequency band, so that the user can reduce the operation of swinging the mobile phone to change the satellite angle when using the first satellite communication antenna 311 to perform satellite communication, and more easily realize the satellite function.

[0141] In addition, as shown in Figure 14As shown, in the case that the first branch 3001 (or the second branch 3002) has a gap between the first branch 3001 (or the second branch 3002) and other branches on both sides of the first branch 3001 (or the second branch 3002), the two 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 an end of the first branch 3001 away from the second branch 3002, so that the first electrical connection end 3101 is arranged at the open end of the first branch 3001, which is beneficial to increasing the aperture of the antenna. Similarly, the second electrical connection end 3201 can be located at an end of the second branch 3002 away from the first branch 3001, so that the second electrical connection end 3201 is arranged at the open end of the second branch 3002, which is beneficial to increasing the aperture of the antenna. In the embodiments of the present application, the open end can not be grounded, and the open end is not electrically connected to other conductive bodies. The open end can also be referred to as a free end, an open end, or an open circuit end. It should be understood that in some embodiments, other conductive bodies can be coupled to the open end to transmit coupled energy (which can be understood as transmitting current).

[0142] The above is an example of taking the antenna structure 31 including the first satellite communication antenna 311 and the first ground network communication antenna 312 as an example. The first satellite communication antenna 311 can be used as a high-orbit satellite communication antenna for transmitting and receiving radio frequency signals of the first satellite operating frequency band (for example, including: an uplink frequency band of 1980 / MHz-2010 / MHz and a downlink frequency band of 2170 / MHz-2200 / MHz). In addition, the first satellite communication antenna 311 can have a 1T1R function or a 1T2R function. In other embodiments of the present application, the first satellite communication antenna 311 can also have two or more satellite transmitting ends and two or more satellite receiving ends, which will not be described one by one herein. In addition, the first ground network communication antenna 312 can be a cellular antenna for transmitting and receiving signals of a cellular communication frequency band.

[0143] In other embodiments of the present application, as shown in the first satellite communication antenna 311 and the first ground network communication antenna 312 are replaced by a second satellite communication antenna 341, and the second satellite communication antenna 341 can include the second branch 3002. Figure 16 In addition, the communication chip 32 can have a second satellite transmitting end SAT2-Tx and a second satellite first receiving end SAT2-Rx1. For example, the communication chip 32 can include a first sub-chip 3211 and a second sub-chip 3222. The first sub-chip 3211 can include the first satellite transmitting end SAT1-Tx and the first satellite first receiving end SAT1-Rx1. Figure 4The first satellite communication chip 321 and the first ground network communication chip 322 are shown. In this case, the first sub-chip 3211 can have the first satellite first receiving end SAT1-Rx1, the first satellite second receiving end SAT1-Rx2, the first satellite first transmitting end SAT1-Tx, and the first ground network transmitting end GN1-Tx. The second sub-chip 3222 can have the second satellite first receiving end SAT2-Rx1 and the second satellite transmitting end SAT2-Tx, which can be referred to as a second satellite communication chip.

[0144] In addition, in some embodiments of the present application, when the second satellite communication antenna 341 is a low-orbit satellite communication antenna, the second satellite transmitting end SAT2-Tx is configured to transmit radio frequency signals in the second satellite operating frequency band (for example, the uplink frequency band 1668 / MHz-1675 / MHz), and the second satellite first receiving end SAT2-Rx1 is configured to receive radio frequency signals in the second satellite operating frequency band (for example, the downlink frequency band 1518 / MHz-1525 / MHz). In this case, the second satellite communication antenna 341 has one transmitting end, i.e., the second satellite transmitting end SAT2-Tx, and one receiving end, i.e., the second satellite first receiving end SAT2-Rx1. Therefore, the second satellite communication antenna 341 can realize 1T1R functionality.

[0145] As described above, the second satellite communication antenna 341 can include the second branch 3002 as a transmitting and receiving antenna of the second satellite communication antenna 341. In addition, the first satellite communication antenna 311 can also include the second branch 3002, which can be used as a receiving antenna of the first satellite communication antenna 311. Therefore, the first satellite communication antenna 311 as a high-orbit satellite antenna and the second satellite communication antenna 341 as a low-orbit satellite antenna can share the same branch, i.e., the second branch 3002, to improve the space utilization of the electronic device 01. In other embodiments of the present application, the first satellite communication antenna 311 can be a low-orbit satellite antenna, and the second satellite communication antenna 341 can be a high-orbit satellite antenna, which is not limited in the present application. For convenience of description, 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 sharing of the first satellite communication antenna 311 and the second satellite communication antenna 341, in order to realize the common feeding of the first satellite communication antenna 311 and the second satellite communication antenna 341, the first satellite communication antenna 311 and the second satellite communication antenna 341 continue to be as shown in FIG. 3A. Figure 16As shown, the antenna device 30 can further include a second radio frequency switch RFS2. The second radio frequency switch RFS2 can be coupled between the first satellite second receiving end SAT1-Rx2 and the second electrical connection end 3201. In addition, the second radio frequency switch RFS2 can also be coupled between the second satellite transmitting end SAT2-Tx and the second electrical connection end 3201, and the second radio frequency switch RFS2 can also be coupled between the second satellite first receiving end SAT2-Rx1 and the second electrical connection end 3201. The second radio frequency switch RFS2 can be used to connect the first satellite second receiving end SAT1-Rx2, the second satellite transmitting end SAT2-Tx or the second satellite first receiving end SAT2-Rx1 with the second electrical connection end 3201. For example, the second radio frequency switch RFS2 can be an SPMT switch, such as an SP4T switch. Alternatively, the second radio frequency switch RFS2 can be a combination of multiple SPST switches, which is not limited in the present application.

[0147] As shown, the antenna device 30 can further include a second radio frequency switch RFS2. The second radio frequency switch RFS2 can be coupled between the first satellite second receiving end SAT1-Rx2 and the second electrical connection end 3201. In addition, the second radio frequency switch RFS2 can also be coupled between the second satellite transmitting end SAT2-Tx and the second electrical connection end 3201, and the second radio frequency switch RFS2 can also be coupled between the second satellite first receiving end SAT2-Rx1 and the second electrical connection end 3201. The second radio frequency switch RFS2 can be used to connect the first satellite second receiving end SAT1-Rx2, the second satellite transmitting end SAT2-Tx or the second satellite first receiving end SAT2-Rx1 with the second electrical connection end 3201. For example, the second radio frequency switch RFS2 can be an SPMT switch, such as an SP4T switch. Alternatively, the second radio frequency switch RFS2 can be a combination of multiple SPST switches, which is not limited in the present application. Figure 16 As shown, the antenna device 30 can further include a second radio frequency switch RFS2. The second radio frequency switch RFS2 can be coupled between the first satellite second receiving end SAT1-Rx2 and the second electrical connection end 3201. In addition, the second radio frequency switch RFS2 can also be coupled between the second satellite transmitting end SAT2-Tx and the second electrical connection end 3201, and the second radio frequency switch RFS2 can also be coupled between the second satellite first receiving end SAT2-Rx1 and the second electrical connection end 3201. The second radio frequency switch RFS2 can be used to connect the first satellite second receiving end SAT1-Rx2, the second satellite transmitting end SAT2-Tx or the second satellite first receiving end SAT2-Rx1 with the second electrical connection end 3201. For example, the second radio frequency switch RFS2 can be an SPMT switch, such as an SP4T switch. Alternatively, the second radio frequency switch RFS2 can be a combination of multiple SPST switches, which is not limited in the present application.

[0148] In this case, the AP can control the DPMP to select the first sub-chip 3211 or the second sub-chip 3222 to control the DPMT switch as needed. For example, when the second branch 3002 needs to be used as a 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 requirement, 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 first satellite second receiving end SAT1-Rx2 of the first sub-chip 3211 with the second electrical connection end 3201.

[0149] Or, when the second branch 3002 needs to be used as a transmitting or receiving antenna of the second satellite communication antenna 341, the AP can control the DPMT switch according to the above-mentioned requirement, 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 with the second electrical connection end 3201.

[0150] In addition, as shown in Figure 16 , the antenna device 30 can further include a third radio frequency test seat 45 and a second impedance matching network 46, which can be connected in series between the second radio frequency switch RFS2 and the second electrical connection end 3201 of the second branch 3002. Among them, the second impedance matching network 46 can perform impedance matching on the communication link of the second satellite communication antenna 341. The third radio frequency test seat 45 can be connected to a test instrument to test and adjust the relevant parameters of the impedance matching of the communication link of the second satellite communication antenna 341.

[0151] Figure 16 The electronic device is a folding machine, and the first branch 3001 and the second branch 3002 are respectively located on both sides of the rotation shaft 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 of the first ground network working frequency band, the above-mentioned first satellite communication antenna 311 can be in a non-working state (i.e. not transmitting and receiving signals). In addition, when the electronic device 01 is in the folding state as shown in Figure 17 , the first metal frame 101a and the second metal frame 101b are stacked, so that the first branch 3001 in the first metal frame 101a and the second branch 3002 in the second metal frame 101b are close to each other, so as to be coupled with each other. Therefore, when the first ground network communication antenna 312 transmits and receives radio frequency signals of the first ground network working frequency band, the second branch 3002 can be used as a parasitic antenna of the first ground network communication antenna 312, thereby increasing the size of the first ground network communication antenna 312, and improving the antenna aperture and gain of the first ground network communication antenna 312. Therefore, when the first ground network communication antenna 312 transmits and receives radio frequency signals of the first ground network working frequency band, the second satellite communication antenna 341 can also be in a non-working state (i.e. not transmitting and receiving signals).

[0152] Based on this, when the electronic device 01 is in the folding state as shown in Figure 17In the folded state as shown, when the first ground-plane communication antenna 312 transmits and receives radio frequency signals in the first ground-plane operating frequency band, in order to avoid the second impedance matching network 46 affecting the signals on the second branch 3002 which is a parasitic antenna of the first ground-plane communication antenna 312, the antenna device 30 can further comprise a second gating switch S2 as shown. Figure 16 The second gating switch S2 can be coupled between the second radio frequency switch RFS2 and the second electrical connection end 3201, and the second gating switch S2 can be located in the clearance 300 of the antenna device 30 (as shown in Figure 3 ).

[0153] In this case, the third radio frequency test seat 45 can be coupled between the second gating switch S2 and the second radio frequency switch RFS2, as shown. Figure 16 In this case, the third radio frequency test seat 45 can be coupled between the second gating switch S2 and the second radio frequency switch RFS2, as shown. Figure 17 In the folded state as shown, the first branch 3001 and the second branch 3002 are coupled to each other, so that the second branch 3002 acts as a parasitic antenna of the first ground-plane communication antenna 312, and when the second branch 3002 transmits and receives radio frequency signals in the first ground-plane operating frequency band (for example, a cellular communication frequency band), the signals on the second branch 3002 will not be affected by the second impedance matching network 46, thereby achieving the purpose of increasing the aperture and gain of the first ground-plane communication antenna 312. Alternatively, a first part of the second impedance matching network 46 is coupled between the second gating switch S2 and the second electrical connection end 3201, and a second part of the second impedance matching network 46 is coupled between the second gating switch S2 and the third radio frequency test seat 45.

[0154] The above is an example in which at least part 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 end 3201. In other embodiments of the present application, at least part of the second impedance matching network 46 can be coupled between the second gating switch S2 and the second electrical connection end 3201. At this time, the technical effects of the second gating switch S2, the second impedance matching network 46 and the third radio frequency test seat 45 are as described above, and will not be described here.

[0155] The above is an example of implementing 1T1R function by the second satellite communication antenna 341. In some other embodiments of the present application, the second satellite communication antenna 341 can also implement 1T2R function. For example, Figure 18 As shown in FIG. 31, the second satellite communication antenna 341 further includes a third branch 3003, which can have a third electrical connection end 3301. The third branch 3003 can be spaced apart from the first branch 3001 and the second branch 3002. The manner in which the third branch 3003 is spaced apart from the first branch 3001 and the second branch 3002 is similar to the manner in which the first branch 3001 is spaced apart from the second branch 3002, which will not be repeated here.

[0156] In addition, as shown in FIG. 31, the communication chip, for example, the second sub-chip 3222 in the communication chip, can further have a second satellite second receiving end SAT2-Rx2 for receiving radio frequency signals of the second satellite operating frequency band (for example, the downlink frequency band 1518 / 1 525 MHz). Figure 18

[0157] In this case, when the second satellite communication antenna 341 transmits radio frequency signals of the above-mentioned second satellite operating frequency band, the second branch 3002 is in an operating state to transmit radio frequency signals of the second satellite operating frequency band. When the second satellite communication antenna 341 receives radio frequency signals of the second satellite operating frequency band, the second branch 3002 and the third branch 3003 are in an operating state at the same time to receive radio frequency signals of the second satellite operating frequency band. In this way, the second satellite communication antenna 341 can have 1T2R function to expand the width and gain of the receiving beam of the second satellite communication antenna 341 and improve the sensitivity of the second satellite communication antenna 341 as a receiving antenna, so that the electronic device 01 is more likely to implement the star function.

[0158] wherein, Figure 18 ​is taken as an example for illustration. In some other embodiments of the present application, a radio frequency switch, for example, SP4T, can be coupled between the second satellite second receiving end SAT2-Rx2 and the third electrical connection end 3301. In this way, according to the needs of the user, the path of the radio frequency switch can be controlled to connect the second satellite second receiving end SAT2-Rx2 and the third electrical connection end 3301, so that the second satellite communication antenna 341 has a 1T2R function. Or, the second satellite second receiving end SAT2-Rx2 and the third electrical connection end 3301 are disconnected, so that the second satellite communication antenna 341 has a 1T1R function.

[0159] As can be seen from the above, Figure 18 when the first satellite communication antenna 311 and the second satellite communication antenna 341 both have a 1T2R function, the first satellite communication antenna 311 includes a first branch 3001 and a second branch 3002, the first branch 3001 can receive and transmit radio frequency signals of the first satellite operating frequency band, and the second branch 3002 can receive radio frequency signals of the first satellite operating frequency band. In the case of a folding machine, the first branch 3001 and the second branch 3002 are respectively arranged on the first metal frame 101a and the second metal frame 101b. Moreover, the first ground network communication antenna 312 shares the first branch 3001 with the first satellite communication antenna 311. In addition, the second satellite communication antenna 341 includes the second branch 3002 and a third branch 3003, the second branch 3002 is used for receiving and transmitting radio frequency signals of the second satellite operating frequency band, and the third branch 3003 is used for receiving radio frequency signals of the second satellite operating frequency band. The second branch 3002 and the third branch 3003 are both arranged on the second metal frame 101b.

[0160] In some other embodiments of the present application, as shown in Figure 19 in the case of a folding machine, the antenna structure 31 of the electronic device 01 can only include the first satellite communication antenna 311 and the second satellite communication antenna 341, both of which have the above-mentioned 1T2R function, and the arrangement of the first satellite communication antenna 311 and the second satellite communication antenna 341 is the same as that shown in Figure 18 herein. Or, as shown in Figure 20As shown in FIG. 1, in the case that the antenna structure 31 can only include the first satellite communication antenna 311 and the second satellite communication antenna 341, the first satellite communication antenna 311 has the 1T2R function as described above, and the second satellite communication antenna 341 can have the 1T1R function. Alternatively, the first satellite communication antenna 311 has the 1T1R function as described above, and the second satellite communication antenna 341 can have the 1T2R function.

[0161] As shown in FIG. 1, in the case that the antenna structure 31 can only include the first satellite communication antenna 311 and the second satellite communication antenna 341, the first satellite communication antenna 311 has the 1T2R function as described above, and the second satellite communication antenna 341 can have the 1T1R function. Alternatively, the first satellite communication antenna 311 has the 1T1R function as described above, and the second satellite communication antenna 341 can have the 1T2R function. Figure 19 As shown in FIG. 1, in the case that the antenna structure 31 can only include the first satellite communication antenna 311 and the second satellite communication antenna 341, the first satellite communication antenna 311 has the 1T2R function as described above, and the second satellite communication antenna 341 can have the 1T1R function. Alternatively, the first satellite communication antenna 311 has the 1T1R function as described above, and the second satellite communication antenna 341 can have the 1T2R function.

[0162] Alternatively, as shown in FIG. 1, in the case that the antenna structure 31 can only include the first satellite communication antenna 311 and the second satellite communication antenna 341, the first satellite communication antenna 311 has the 1T2R function as described above, and the second satellite communication antenna 341 can have the 1T1R function. Alternatively, the first satellite communication antenna 311 has the 1T1R function as described above, and the second satellite communication antenna 341 can have the 1T2R function. Figure 21 Alternatively, as shown in FIG. 1, in the case that the antenna structure 31 can only include the first satellite communication antenna 311 and the second satellite communication antenna 341, the first satellite communication antenna 311 has the 1T2R function as described above, and the second satellite communication antenna 341 can have the 1T1R function. Alternatively, the first satellite communication antenna 311 has the 1T1R function as described above, and the second satellite communication antenna 341 can have the 1T2R function.

[0163] On this basis, as shown in FIG. 3, in the case that the first satellite communication antenna 311 includes the first branch 3001 and the second branch 3002, and the second satellite communication antenna 341 includes the second branch 3002 and the first branch 3001, the antenna structure 31 can further include a first terrestrial communication antenna 312, which can multiplex the first branch 3001 with the first satellite communication antenna 311 and the second satellite communication antenna 341. Figure 22 The first terrestrial communication antenna 312 can be arranged in the same way as the first satellite communication antenna 311 and the second satellite communication antenna 341, and has the same technical effects as the first satellite communication antenna 311 and the second satellite communication antenna 341. Details are not described herein again.

[0164] The above is an example of the electronic device 01 with the antenna structure 31 including the first satellite communication antenna 311, the second satellite communication antenna 341, and the first terrestrial communication antenna 312, which is a foldable machine. In other embodiments of the present application, as shown in FIG. 4, the electronic device 01 can be a straight machine. Similarly, the first satellite communication antenna 311 includes the first branch 3001 and the second branch 3002, the second satellite communication antenna 341 includes the second branch 3002 and the first branch 3001, and the first terrestrial communication antenna 312 can multiplex the first branch 3001 with the first satellite communication antenna 311 and the second satellite communication antenna 341. As described 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 terrestrial communication antenna 312. Therefore, in order to improve the gain of the above-mentioned antennas and facilitate the pointing operation of the satellite antenna, the first branch 3001 can be arranged as the middle branch of the top frame 1011 of the metal frame. Figure 23 The above is an example of the electronic device 01 with the antenna structure 31 including the first satellite communication antenna 311, the second satellite communication antenna 341, and the first terrestrial communication antenna 312, which is a foldable machine. In other embodiments of the present application, as shown in FIG. 4, the electronic device 01 can be a straight machine. Similarly, the first satellite communication antenna 311 includes the first branch 3001 and the second branch 3002, the second satellite communication antenna 341 includes the second branch 3002 and the first branch 3001, and the first terrestrial communication antenna 312 can multiplex the first branch 3001 with the first satellite communication antenna 311 and the second satellite communication antenna 341. As described 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 terrestrial communication antenna 312. Therefore, in order to improve the gain of the above-mentioned antennas and facilitate the pointing operation of the satellite antenna, the first branch 3001 can be arranged as the middle branch of the top frame 1011 of the metal frame. Figure 23 The above is an example of the electronic device 01 with the antenna structure 31 including the first satellite communication antenna 311, the second satellite communication antenna 341, and the first terrestrial communication antenna 312, which is a foldable machine. In other embodiments of the present application, as shown in FIG. 4, the electronic device 01 can be a straight machine. Similarly, the first satellite communication antenna 311 includes the first branch 3001 and the second branch 3002, the second satellite communication antenna 341 includes the second branch 3002 and the first branch 3001, and the first terrestrial communication antenna 312 can multiplex the first branch 3001 with the first satellite communication antenna 311 and the second satellite communication antenna 341. As described 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 terrestrial communication antenna 312. Therefore, in order to improve the gain of the above-mentioned antennas and facilitate the pointing operation of the satellite antenna, the first branch 3001 can be arranged as the middle branch of the top frame 1011 of the metal frame.

[0165] In addition, in some embodiments of the present application, as shown in FIG. 5, Figure 24As shown, the antenna structure 31 can further include a third satellite communication antenna 351. The third satellite communication antenna 351 can include a fourth branch 3004 having a fourth electrical connection end 3401. The communication chip 32 can further have a third satellite transmitting end SAT3-Tx and a third satellite receiving end SAT3-Rx. In an example, the third satellite communication antenna 351 can be a high orbit satellite communication antenna, and the third satellite communication antenna 351 can be used only for transmitting and receiving short messages, and the third satellite communication antenna can also be referred to as a satellite short message antenna. In this case, the third satellite transmitting end SAT3-Tx is used to transmit radio frequency signals of a third satellite operating frequency band (uplink frequency band 610 / MHz-1626 / MHz), and the third satellite receiving end SAT3-Rx is used to receive radio frequency signals of a third satellite operating frequency band (downlink frequency band 2483 / MHz-2500 / MHz).

[0166] In an example, Figure 24 As shown, the communication chip 32 can further include a third sub-chip 3233 in addition to the first sub-chip 3211 and the second sub-chip 3222. The third sub-chip 3233 can have the third satellite transmitting end SAT3-Tx and the third satellite receiving end SAT3-Rx. In addition, in order to enable the third satellite transmitting end SAT3-Tx and the third satellite receiving end SAT3-Rx, the antenna device 30 can further include a third radio frequency switch RFS3. The third radio frequency switch RFS3 can be coupled between the third satellite transmitting end SAT3-Tx and the fourth electrical connection end 3401 of the fourth branch 3004. The third radio frequency switch RFS3 is also coupled between the third satellite receiving end SAT3-Rx and the fourth electrical connection end 3401. The third radio frequency switch RFS3 can be used to connect the third satellite transmitting end SAT3-Tx or the third satellite receiving end SAT3-Rx with the fourth electrical connection end 3401. In an example, the third radio frequency switch RFS3 can be an SPMT switch, for example, an SP4T switch. Alternatively, the third radio frequency switch RFS3 can be a combination of multiple SPST switches, which is not limited in the present application.

[0167] In this case, when the third sub-chip 3233 controls the third radio frequency switch RFS3 to connect the third satellite transmitting end SAT3-Tx with the fourth electrical connection end 3401, the fourth branch 3004 can serve as a transmitting antenna of the third satellite communication antenna 351 to transmit radio frequency signals of the third satellite operating frequency band (uplink frequency band 610 / MHz-1626 / MHz). When the third sub-chip 3233 controls the third radio frequency switch RFS3 to connect the third satellite receiving end SAT3-Rx with the fourth electrical connection end 3401, the fourth branch 3004 can serve as a receiving antenna of the third satellite communication antenna 351 to receive radio frequency signals of the third satellite operating frequency band (downlink frequency band 2483 / MHz-2500 / MHz).

[0168] Based on this, in some embodiments of the present application, in the case of the folding machine as shown in Figure 24 The antenna structure 31 of the electronic device 01 can include a first ground network communication antenna 312, a first satellite communication antenna 311, a second satellite communication antenna 341, and the third satellite communication antenna 351 described above. As described 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 can include a first branch 3001 as a transceiving antenna of the first satellite communication antenna 311 and a second branch 3002 as a receiving antenna of the first satellite communication antenna 311, so that the first satellite communication antenna 311 has the 1T2R function described above. The second satellite communication antenna 341 can include a second branch 3002 and a third branch 3003. The second branch 3002 can also be multiplexed as a transceiving antenna of the second satellite communication antenna 341, and the third branch 3003 as a receiving antenna of the second satellite communication antenna 341, so that the second satellite communication antenna 341 has a 1T2R function.

[0170] Continuing as shown in Figure 24 The fourth branch 3004 of the third satellite communication antenna 351 can be spaced apart from the first branch 3001. In the case where the antenna structure 31 further includes the second branch 3002 and the third branch 3003, the fourth branch 3004 and the second branch 3002 and the third branch 3003 are all spaced apart. The way different branches are spaced apart is as described above, and will not be described again 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] In addition, when the third satellite communication antenna 351 transmits and receives radio frequency signals of the third satellite operating frequency band, the second satellite communication antenna 341 and the first satellite communication antenna 311 can be in a non-working state. At this time, the second gating switch S2 can be controlled to disconnect at least a part of the second impedance matching network 46 from the second electrical connection end 3201 of the second branch 3002. In this way, the second branch 3002 and the fourth branch 3004 can be coupled to each other, so that the second branch 3002 acts as a parasitic antenna of the third satellite communication antenna 351, and when the second branch 3002 transmits and receives radio frequency signals of the third satellite operating frequency band, the signals on the second branch 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 embodiments of the present application, in the case that the electronic device 01 is a folding machine as shown in FIG. 1B, the antenna structure 31 of the electronic device 01 can include the first satellite communication antenna 311, the second satellite communication antenna 341, and the third satellite communication antenna 351. Among them, the first satellite communication antenna 311 has the above-mentioned 1T2R function, and the second satellite communication antenna 341 can have the 1T1R function. The third satellite communication antenna 351 and the second satellite communication antenna 341 are located on the same metal frame, for example, the second metal frame 101b. Figure 25 Alternatively, in some embodiments of the present application, in the case that the electronic device 01 is a folding machine as shown in FIG. 1B, the antenna structure 31 of the electronic device 01 can include the first satellite communication antenna 311, the second satellite communication antenna 341, and the third satellite communication antenna 351.

Among them, the first satellite communication antenna 311 has the above-mentioned 1T2R function, and the second satellite communication antenna 341 can have the 1T1R function. The third satellite communication antenna 351 and the second satellite communication antenna 341 are located on the same metal frame, for example, 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 radio frequency switch RFS3 to connect the third satellite transmitting end SAT3-Tx or the third satellite receiving end SAT3-Rx with the fourth electrical connection end 3401, the fourth branch 3004 can serve as a transceiving antenna of the third satellite communication antenna 351 to transmit radio frequency signals in the third satellite operating frequency band. When the third sub-chip 3233 controls the third radio frequency switch RFS3 to connect the positioning satellite receiving end SAT4-Rx with the fourth electrical connection end 3401, the fourth branch 3004 can serve as a receiving antenna of the satellite positioning antenna 361 to receive radio frequency signals in the fourth satellite operating frequency band.

[0179] In some embodiments of the present application, as shown in Figure 30 The antenna structure 31 can further include a second ground network communication antenna 371, which can include the fourth branch 3004. In this case, the second ground network communication antenna 371 can share the fourth branch 3004 with the satellite positioning antenna 361 and the third satellite communication antenna 351. In addition, the third sub-chip 3233 in the communication chip 32 further has a second ground network transmitting end GN2-Tx. The second ground network transmitting end GN2-Tx is used to transmit radio frequency signals in a second ground network operating frequency band. For example, the second ground network communication antenna 371 can be a WIFI antenna or a cellular antenna. Hereinafter, taking the second ground network communication antenna 371 as a WIFI antenna as an example, the second ground network operating frequency band can include a WIFI 2.4G frequency band (2400 / MHz-2483.5 / MHz).

[0180] In addition, as shown in Figure 30 The third radio frequency switch RFS3 is further coupled between the second ground network transmitting end GN2-Tx and the fourth electrical connection end 3401. The third radio frequency switch RFS3 is used to connect the third satellite transmitting end SAT3-Tx, the third satellite receiving end SAT3-Rx, the positioning satellite receiving end SAT4-Rx, or the second ground network transmitting end GN2-Tx with the fourth electrical connection end 3401. Similarly, when the third sub-chip 3233 controls the third radio frequency switch RFS3 to connect the second ground network transmitting end GN2-Tx with the fourth electrical connection end 3401, the fourth branch 3004 can serve as a transceiving antenna of the second ground network communication antenna 371 to transceive signals in the second ground network operating frequency band (e.g., 2400 / MHz-2483.5 / MHz). The process of the third radio frequency switch RFS3 connecting the third satellite transmitting end SAT3-Tx, the third satellite receiving end SAT3-Rx, and the positioning satellite receiving end SAT4-Rx with the fourth electrical connection end 3401 is as described above, and will not be described here again.

[0181] The above is an example of taking the fourth branch 3004 as the second ground network communication antenna 371, the satellite positioning antenna 361, and the third satellite communication antenna 351. In other embodiments of the application, the fourth branch 3004 can be multiplexed as any two of the second ground network communication antenna 371, the satellite positioning antenna 361, and the third satellite communication antenna 351. In addition, Figure 30 is an example of taking the third satellite transmitting end SAT3-Tx, the third satellite receiving end SAT3-Rx, the positioning satellite receiving end SAT4-Rx, and the second ground network transmitting end GN2-Tx integrated in one communication chip, for example, the third sub-chip 3233. In other embodiments of the application, the third satellite transmitting end SAT3-Tx and the third satellite receiving end SAT3-Rx can be arranged in the same chip, and the third satellite receiving end SAT3-Rx and the positioning satellite receiving end SAT4-Rx can be arranged in different chips.

[0182] In other embodiments of the application, as shown in Figure 30 , the antenna structure 31 can also include a third ground network communication antenna 381, which can include a fifth branch 3005 having a fifth electrical connection end 3501. The fifth branch 3005 can be arranged apart from the first branch 3001. For example, when the electronic device 01 is a folding machine as shown in Figure 30 , 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. In addition, the fifth branch 3005 can also be located on the same metal frame, for example, the second metal frame 101b, with the second branch 3002, the third branch 3003, and the fourth branch 3004. And the fifth branch 3005 is arranged apart from the second branch 3002, the third branch 3003, and the fourth branch 3004.

[0183] In addition, the communication chip 32 also has a third ground network transmitting end GN3-Tx for transmitting radio frequency signals of a third ground network operating frequency band. For example, the 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 above-mentioned third ground network operating frequency band can include a WIFI 5G frequency band (5150 / MHz~5825 / MHz). And the third ground network transmitting end GN3-Tx can be coupled with the fifth electrical connection end 3501 of the fifth branch 3005. In this way, the fifth branch 3005 can be used as the third ground network communication antenna 381 for transmitting and receiving signals of the third ground network operating frequency band.

[0184] In some other embodiments of the present application, the third ground net transmitting end GN3-Tx and the fifth electric connecting end 3501 of the fifth branch 3005 can be coupled with a radio frequency switch to select whether the third ground net communication antenna 381 is in working state or not according to needs.

[0185] Figure 30 The antenna structure 31 of the electronic device 01 includes the first ground net communication antenna 312, the first satellite communication antenna 311, the second satellite communication antenna 341, the third satellite communication antenna 351, the satellite positioning antenna 361, the second ground net communication antenna 371, and the third ground net communication antenna 381. In this case, the electronic device 01 can integrate three satellite antennas, i.e., the first satellite communication antenna 311 and the second satellite communication antenna 341 for voice call and short message transmission, and the third satellite communication antenna 351 for short message transmission, so that at least three satellite communication antennas can be integrated in the limited space of the electronic device 01.

[0186] In this way, the user can select different satellite antennas for communication according to different needs or regions where the user is located, so as to improve the user experience. For example, as shown in Figure 31 , the electronic device 01 can display options of multiple satellite antennas on a satellite communication interface. The user can select to turn on at least one satellite antenna function by hand touch button 50. Alternatively, the display interface of the electronic device 01 can recommend satellite antennas that can be used to the user according to the region where the user is located. For example, as shown in Figure 31 , the user can select whether to turn on the recommended satellite antenna function according to the content in the prompt box 51. Among them, the “Y” button in the prompt box 51 indicates to turn on the first satellite communication antenna, and the “N” button indicates not to turn on the first satellite communication antenna.

[0187] The following takes the antenna structure 31 shown in Figure 30 as an example to illustrate the control process of the first satellite communication antenna 311, the second satellite communication antenna 341, and the third satellite communication antenna 351. For example, the control process of the first satellite communication antenna 311 can include S101-S106 shown in Figure 32 .

[0188] S101, receiving an operation instruction of a user interface.

[0189] For example, the operation instruction of S101 can be an operation instruction generated when the user triggers the button 50 in Figure 31 , or an operation instruction generated when the user triggers the “Y” button in the prompt box 51 shown in Figure 31 . The above operation instructions are all used to indicate that the user needs to turn on the first satellite communication antenna.

[0190] S102, the AP issues a communication module.

[0191] For example, the AP can issue the communication module to the first sub-chip 3211 in the antenna device according to the operation instruction in S101. Figure 30

[0192] S103, the AP switches the control of the switch.

[0193] For example, the AP can determine the priority of each radio switch and the gating switch in the antenna device according to the operation instruction in S101, and switch the control of the above switches according to the priority.

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

[0195] For example, Figure 30 The first sub-chip 3211 in the antenna device can start the first satellite communication mode according to the communication module issued by the AP in S102 and the result of the AP switching the control of the switch in S103, so that the first satellite communication antenna 311 is in a working state.

[0196] S105, the first sub-chip issues a switch control instruction.

[0197] For example, Figure 33 The first sub-chip 3211 in the antenna device can issue a switch control instruction to the first radio switch RFS1, the first gating switch S1 and the second radio switch RFS2. In this case, the first radio switch RFS1 can turn on the first satellite transmitting end SAT1-Tx or the first satellite first receiving end SAT1-Rx1 and the first gating switch S1 under the control of the control signal issued by the first sub-chip 3211. The first gating switch S1 can turn on the first radio switch RFS1 and the first electrical connection end 3101 of the first branch 3001 under the control of the control signal issued by the first sub-chip 3211, so that the first branch 3001 can serve as the first satellite communication antenna 311. In addition, the second radio switch RFS2 can turn on the first satellite second receiving end SAT1-Rx2 and the second electrical connection end 3201 of the second branch 3002 under the control of the control signal issued by the first sub-chip 3211, so that the second branch 3002 serves as the receiving antenna of the first satellite communication antenna 311.

[0198] In addition, continue as Figure 33 ​As 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.

[0199] S106, the first sub-chip transmits and receives radio frequency signals in the operating frequency band of the first satellite.

[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.

[0201] In other embodiments of this application, when the electronic device 01 turns on the second satellite communication antenna 341 according to the user interface operation, the control method of the second satellite communication antenna 341 is the same as... 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.

[0202] In addition, as shown in Figure 34 The second satellite communication antenna 341 can further include a fourth branch 3004, a fifth branch 3005, a sixth branch 3006 and a seventh branch 3007 as parasitic branches, which are coupled with the tuning switch assembly 40. The second sub-chip 3222 can send control instructions to each tuning switch assembly 40, so that the parasitic branches can serve as the transceiving antenna of the second satellite communication antenna 341, achieving the purpose of adjusting the antenna aperture of the second satellite communication antenna 341.

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

[0204] In some other embodiments of the present application, when the electronic device 01 turns on the third satellite communication antenna 351 according to the user interface operation, the control method of the third satellite communication antenna 351 can be obtained in the same way as Figure 32 shown in the method. Among them, Figure 35 The third sub-chip 3233 in the third satellite communication antenna 351 can send a switch control instruction to the third radio frequency switch RFS3. In this case, the third radio frequency switch RFS3 can connect the third satellite transceiving end SAT3-Tx or the third satellite receiving end SAT3-Rx with the fourth electrical connection end 3401 of the fourth branch 3004 under the control of the control signal sent by the third sub-chip 3233, so that the fourth electrical connection end 3401 can serve as the transceiving antenna of the third satellite communication antenna 351.

[0205] In addition, as shown in Figure 35As shown, the third satellite communication antenna 351 can also include a second branch 3002 as a parasitic antenna. The parasitic branch is coupled with a tuning switch assembly 40. The third sub-chip 3233 can send control instructions to each tuning switch assembly 40, so that the parasitic branch can serve as a transceiving antenna of the third satellite communication antenna 351, achieving the purpose of adjusting the antenna aperture of the third satellite communication antenna 351.
