Description

Technical Field

[0001] The present disclosure relates to the field of antenna technology, and in particular to an antenna module and an electronic device. Background Art

[0002] Non-terrestrial network (NTN) direct satellite connection means that satellites provide 5G (fifth-generation mobile communication technology) connection services directly to the ground through NTN technology, thereby enabling mobile phones to communicate with each other. NTN technology is an important supplement to ground cellular communication technology. It is not restricted by terrain and can provide ubiquitous coverage, connecting the multi-dimensional space of air, space, land and sea to form an integrated ubiquitous access network and realize on-demand access in all scenarios.

[0003] For various mobile or fixed electronic communication devices, such as laptops, which are an important form of mobile communication devices, there is a potential demand for using NTN to access the Internet in the future. At the same time, with the rapid development of wireless communication technology, modern electronic devices are constantly evolving towards miniaturization and multi-functionality. The contradiction between the compression of the internal space of the device and the demand for the antenna system is becoming increasingly prominent. The space available for antennas in electronic devices (such as all-metal laptops) is very limited.

[0070] The following will be combined with the drawings in the embodiments of the present disclosure to clearly and completely describe the technical solutions in the embodiments of the present disclosure. It is understood that the specific embodiments described herein are only used to explain the relevant disclosure, rather than to limit the disclosure. It should also be noted that, for the convenience of description, only the parts related to the relevant disclosure are shown in the drawings.

[0071] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which the present disclosure belongs. The terms used herein are only for the purpose of describing the embodiments of the present disclosure and are not intended to limit the present disclosure.

[0072] In the following description, reference is made to “some embodiments”, which describe a subset of all possible embodiments, but it will be understood that “some embodiments” may be the same subset or different subsets of all possible embodiments and may be combined with each other without conflict.

[0073] It should be pointed out that the terms "first\second\third" involved in the embodiments of the present disclosure are merely used to distinguish similar objects and do not represent a specific ordering of the objects. It can be understood that "first\second\third" can be interchanged in a specific order or sequence where permitted, so that the embodiments of the present disclosure described here can be implemented in an order other than that illustrated or described here.

[0074] Take laptops as an example. As an important form of mobile communication equipment, there is a potential demand for using NTN to access the Internet in the future. However, the space available for antennas in laptops (such as all-metal laptops) is very limited, and satellite communications require high-gain antennas, resulting in a contradiction between the area of ​​electronic devices and the space required for antennas.

[0075] Based on this, an embodiment of the present disclosure provides an antenna module, which includes: an antenna unit, including a first antenna and a second antenna arranged at intervals; a plurality of radiator structures arranged at intervals between the first antenna and the second antenna, which are used to assist the antenna unit in receiving and transmitting wireless signals and / or isolate the wireless signals between the first antenna and the second antenna in different usage modes; wherein the antenna unit can receive and transmit wireless signals for different communication modules in different usage modes, and when receiving and transmitting wireless signals of corresponding frequency bands for different communication modules, at least one of the plurality of radiator structures switches between participating in receiving and transmitting wireless signals and participating in isolating wireless signals. In this way, at least one of the radiator structures in the multiplexing antenna module is used to transmit and receive wireless signals in different usage modes, and at the same time, the radiator structures in the multiplexing antenna module are used to transmit and receive wireless signals and isolate wireless signals in different usage modes, respectively, without having to set all the required antenna modules for different communication modules, which is conducive to the miniaturization and multifunctionality of the antenna module. The antenna module has a small space requirement and high space utilization, and can be applied to various electronic devices, especially miniaturized electronic devices, such as all-metal laptops, etc.

[0076] The embodiments of the present disclosure will be described in detail below with reference to the accompanying drawings.

[0077] In one embodiment of the present disclosure, see Figure 1 , which shows a schematic diagram of the structure of an antenna module provided by an embodiment of the present disclosure Figure 1 .like Figure 1 As shown, the antenna module 10 includes:

[0078] The antenna unit 20 includes a first antenna 201 and a second antenna 202 which are spaced apart from each other;

[0079] A plurality of radiator structures 30 are arranged at intervals between the first antenna 201 and the second antenna 202, and are used to assist the antenna unit 20 in receiving and transmitting wireless signals and / or to isolate the wireless signals between the first antenna 201 and the second antenna 202 in different usage modes;

[0080] Among them, the antenna unit 20 can transmit and receive wireless signals for different communication modules in different usage modes. When transmitting and receiving wireless signals of corresponding frequency bands for different communication modules, at least one of the multiple radiator structures 30 switches between participating in transmitting and receiving wireless signals and participating in isolating wireless signals.

[0081] It should be noted that in Figure 13 radiator structures 30 are shown as examples, which are respectively recorded as 30-1, 30-2 and 30-3 for easy distinction. In other examples, there may be 5, 7 or other number of radiator structures 30, which is not specifically limited. The first antenna 201 and the second antenna 202 may also be recorded as the main antenna (Main) and the auxiliary antenna (Aux), respectively, which together may constitute a 2×2 Multiple-Input Multiple-Output (2×2 MIMO) antenna unit.

[0082] It should also be noted that the antenna module 10 may also include multiple communication modules (not shown in the figure), or the communication module may not be included in the antenna module 10, but is included in an electronic device that uses the antenna module 10 for communication, and there is no specific limitation on this. The antenna module 10 supports at least two usage modes, each usage mode corresponds to a different frequency band of the wireless signal, and each usage mode corresponds to its own communication module. Exemplarily, the communication module can be a satellite communication module, a wireless local area network (WLAN) communication module, a wireless wide area network (WWAN) communication module, and the like.

[0083] The antenna unit 20 composed of the first antenna 201 and the second antenna 202 is the main structure for transmitting and receiving wireless signals, and the radiator structure 30 is an auxiliary structure for assisting in transmitting and receiving wireless signals. The radiator structure 30 can participate in transmitting and receiving wireless signals, and perform power synthesis together with the first antenna 201 and the second antenna 202 to improve the communication gain in the corresponding usage mode; the radiator structure 30 can also be used to isolate wireless signals to increase the isolation effect between the first antenna 201 and the second antenna 202 in the corresponding usage mode, thereby improving antenna performance.

[0084] Among the multiple radiator structures 30, some of the radiator structures 30 may be fixed to isolate wireless signals, and / or some of the radiator structures 30 may be fixed to receive and send wireless signals, and / or some of the radiator structures 30 may switch between receiving and sending wireless signals and isolating wireless signals according to the usage mode, that is, in different usage modes, the radiator structure 30 may participate in both receiving and sending wireless signals and isolating wireless signals. The specific setting may be based on the signal frequency band requirements corresponding to the actual communication module, and no specific limitation is made to this.

[0085] In this way, the multiplexing antenna unit 20 can realize the reception and transmission of wireless signals in different usage modes. At the same time, in different usage modes, the working mode of the radiator structure 30 can be switched based on different usage modes. The radiator structure 30 in the multiplexing antenna module 10 plays the role of receiving and transmitting wireless signals and isolating wireless signals respectively. It is not necessary to set all the required antenna modules for different communication modules to meet different frequency band requirements. The antenna module 10 is efficiently utilized in a limited space, the space utilization efficiency is improved, and it is conducive to the miniaturization and multifunctionality of the antenna module. Since the antenna module 10 has a small space requirement and a high space utilization rate, it can be applied to various electronic devices, especially miniaturized electronic devices, such as all-metal laptops, etc.

[0086] In the subsequent description, the antenna module 10 is exemplarily described by taking two usage modes as an example. It can be understood that the relevant description is only a specific implementation method and does not constitute a limitation on the specific structure of the antenna module 10.

[0087] In some embodiments, Figure 1 As shown, the plurality of radiator structures 30 include a first radiator structure 30-1 and a second radiator structure 30-2 and a third radiator structure 30-3 disposed on opposite sides of the first radiator structure 30-1 facing the first antenna 201 and the second antenna 202 respectively;

[0088] The first radiator structure 30 - 1 is used to isolate the wireless signal between the first antenna 201 and the second antenna 202 ;

[0089] The second radiator structure 30-2 and the third radiator structure 30-3 can assist at least one antenna (the first antenna 201 and / or the second antenna 202) in the antenna unit 20 in transmitting and receiving wireless signals when the antenna unit 20 transmits and receives wireless signals of the corresponding frequency band for the first communication module;

[0090] The second radiator structure 30-2 and the third radiator structure 30-3 can also cooperate with the first radiator structure 30-1 to isolate the wireless signal between the first antenna 201 and the second antenna 202 when the antenna unit 20 receives and transmits wireless signals of the corresponding frequency band for the second communication module.

[0091] It should be noted that if Figure 1As shown, the radiator structures 30 are all located between the first antenna 201 and the second antenna 202. The three radiator structures 30 and the two antennas can be arranged in sequence along a certain direction, wherein the first radiator structure 30-1 is located in the middle position and is fixed to isolate the wireless signal between the first antenna 201 and the second antenna 202; on both sides of the first radiator structure 30-1 are the second radiator structure 30-2 and the third radiator structure 30-3, respectively, and the second radiator structure 30-2 and the third radiator structure 30-3 can switch between two working modes: sending and receiving wireless signals and isolating wireless signals.

[0092] Assume that the two usage modes are the first usage mode and the second usage mode, the communication module corresponding to the first usage mode is the first communication module, and the corresponding wireless signal frequency band is the first frequency band, and the communication module corresponding to the second usage mode is the second communication module, and the corresponding wireless signal frequency band is the second frequency band.

[0093] The first use mode usually corresponds to a use mode with a higher gain requirement, such as a satellite communication mode. The corresponding first communication module is a satellite communication module, and the required communication frequency bands are L band (1-2 GHz) and S band (2-4 GHz), for example, about 2.1 GHz. Satellite communication generally needs to cover a distance of tens of thousands of kilometers. Due to long-distance transmission, it has high path loss. In order to ensure signal quality, the gain requirement of the antenna module 10 is relatively high. Therefore, in this use mode, the second radiator structure 30-2 and the third radiator structure 30-3 switch to the role of assisting the antenna to receive and send wireless signals. Here, it can be to assist one of the first antenna 201 and the second antenna 202 to receive and send wireless signals, or it can be to assist the first antenna 201 and the second antenna 202 to receive and send wireless signals. At the same time, the isolation effect of the first radiator structure 30-1 can increase the antenna spacing or adjust the signal radiation field between the first antenna 201 and the second antenna 202, improve the overall aperture of the antenna during power synthesis, and obtain a better maximum gain direction of the antenna during satellite communication.

[0094] The gain requirement of the second usage mode is usually lower than that of the first usage mode. For example, the second usage mode may be a usage mode corresponding to WLAN communication, and the corresponding second communication module is a WLAN communication module, and the frequency band is, for example, about 2.4 GHz. Since WLAN is mainly used for indoor or short-distance communication, the signal transmission path is short and the loss is small, so the gain requirement is low. At the same time, the signal is greatly affected by obstacles, and there will be multipath effects, which places higher performance requirements on the antenna module 10. Therefore, in this usage mode, the second radiator structure 30-2 and the third radiator structure 30-3 cooperate with the first radiator structure 30-1 to isolate the wireless signal between the first antenna 201 and the second antenna 202. At this time, the three radiator structures 30 act as isolation branches together, and the coupling current between the first antenna 201 and the second antenna 202 will be disturbed by the isolation branches, thereby reducing the strength of the signals received by the first antenna 201 and the second antenna 202, improving the isolation, avoiding poor signal quality caused by signal interference, and improving the antenna performance under WLAN communication.

[0095] It should also be noted that, for the satellite communication mode, in order to adjust the antenna resonant frequency to meet the satellite communication, only the first antenna 201, the second radiator structure 30-2 and the third radiator structure 30-3 (3 antennas) can be used to complete beam synthesis, but compared with the method of (first antenna 201 + second antenna 202 + second radiator structure 30-2 + ​​third radiator structure 30-3) a total of 4 antennas, the antenna gain of 3 antennas is less than the antenna gain of 4 antennas, for example, about 1.3dB less. Therefore, in the case where the second antenna 202 must be used in the WLAN communication mode in the communication system, it is more cost-effective to use 4 antennas for power synthesis in the satellite communication mode. That is, in the satellite communication mode, it is preferred that the first antenna 201 + the second antenna 202 jointly transmit and receive wireless signals, and it is secondarily preferred that only the first antenna 201 or the second antenna 202 transmit and receive wireless signals.

[0096] On the basis of the foregoing, and / or, there is a first spacing between the phase center of the second radiator structure 30-2 and the phase center of the first radiator structure 30-1, there is a second spacing between the phase center of the third radiator structure 30-3 and the phase center of the first radiator structure 30-1, and the first spacing is the same as or different from the second spacing.

[0097] It should be noted that, when participating in the transmission and reception of wireless signals, the radiator structure 30 itself also acts as an antenna. The phase center of the antenna refers to the equivalent point source position of the electromagnetic radiation of the antenna, that is, the phase center is an equivalent point, near which the phase change of the radiated wave is minimal, or it is approximately uniformly diffused outward with this point as the center. Ideally, if the antenna is a point source, its phase center coincides with the physical center. However, for actual antennas, due to the complexity of the structure, the phase center may deviate from the center of the physical position of the antenna.

[0098] In the embodiment of the present disclosure, in the satellite communication mode, the second radiator structure 30-2 and the third radiator structure 30-3 both participate in the transmission and reception of wireless signals, and the first spacing and the second spacing may be the same or different. If they are the same, the coupling effects between the second radiator structure 30-2 and the third radiator structure 30-3 and the first antenna 201 and the second antenna 202 are basically the same; if they are different, the degree of coupling effects between the second radiator structure 30-2 and the third radiator structure 30-3 and the first antenna 201 and the second antenna 202 are different. Specifically, it can be reasonably set in combination with the actual use environment and the structure and parameters of the antenna to match different usage scenarios and give full play to the optimal performance of the antenna module 10.

[0099] In some embodiments, Figure 2 As shown, the antenna module 10 further includes an antenna ground 101, the first antenna 201 includes a first radiating body 2011 and a first feeding circuit 2012, the first feeding circuit 2012 is connected to the first feeding port of the first radiating body 2011 and the antenna ground 101, and is used to provide an excitation current to the first radiating body 2011;

[0100] The second antenna 202 includes a second radiating body 2021 and a second feeding circuit 2022 . The second feeding circuit 2022 is connected to a second feeding port of the second radiating body 2021 and the antenna ground 101 to provide an excitation current to the second radiating body 2021 .

[0101] It should be noted that if Figure 2 As shown, it only shows a simple schematic diagram of the first feeding circuit 2012 and the second feeding circuit 2022, which is mainly used to indicate the connection between the feeding circuit and the corresponding radiating body. The antenna ground 101 is the grounding terminal of the antenna module 10, which is used to provide a unified potential reference point for the antenna module 10, ensure the effective transmission and reception of signals, reduce the mutual coupling effect between antennas, and play a role in grounding protection.

[0102] The first radiating body 2011 has a first feeding port (the feeding port can also be called a feeding point), which serves as a connection end between the first radiating body 2011 and the first feeding circuit 2012 ; the second radiating body 2021 has a second feeding port, which serves as a connection end between the second radiating body 2021 and the second feeding circuit 2022 .

[0103] It should also be noted that the first feeding circuit 2012 is a circuit that provides an excitation current for the first radiating body 2011. The excitation current refers to the current formed when the electrons in the antenna are excited to vibrate when the electromagnetic wave irradiates the antenna. The first feeding circuit 2012 can be a voltage source or a current source. The voltage source generates a voltage, which in turn generates a current on the antenna, and the current source can directly provide a current. In either case, an excitation current will eventually be formed on the antenna. The second feeding circuit 2022 is similar, and will not be described here.

[0104] It should also be noted that the excitation current provided by the first feeding circuit 2012 to the first radiating body 2011 and the excitation current provided by the second feeding circuit 2022 to the second radiating body 2021 may be the same or different, which is specifically related to the actual antenna structure, parameters, working frequency band, power requirements, etc. For example, the first radiating body 2011 and the second radiating body 2021 are exactly the same, and the excitation currents provided to the two may be the same or different; for another example, the first radiating body 2011 and the second radiating body 2021 are not exactly the same, and the excitation currents provided to the two may still be the same or different. That is, in actual use, the power of the first antenna 201 and the second antenna 202 may be exactly the same or different.

[0105] And / or, the first feeding circuit 2012 provides different excitation currents to the first radiating body 2011 in a mode in which the antenna unit 20 is used by the first communication module and in a mode in which the antenna unit 20 is used by the second communication module; the second feeding circuit 2022 provides different excitation currents to the second radiating body 2021 in a mode in which the antenna unit 20 is used by the first communication module and in a mode in which the antenna unit 20 is used by the second communication module.

[0106] It should be noted that, since different usage modes have different requirements for antenna gain and performance, the two feeding circuits provide different excitation currents to their respective corresponding radiating bodies in different usage modes so as to operate in different frequency bands. For example, when the antenna unit 20 is used by a satellite communication module, the first feeding circuit 2012 provides an excitation current A1 to the first radiating body 2011; when the antenna unit 20 is used by a WLAN communication module, the first feeding circuit 2012 provides an excitation current A2 to the first radiating body 2011. Since satellite communication has high gain requirements and WLAN communication has short-distance and low-loss characteristics, the excitation current A1 corresponding to satellite communication is usually greater than the excitation current A2 corresponding to WLAN communication to ensure the best communication effect in each usage mode. The same is true for the second feeding circuit 2022, which will not be repeated here.

[0107] In some embodiments, Figure 2 As shown, the first radiator structure 30 - 1 is connected to the antenna ground 101 to isolate the wireless signal between the first antenna 201 and the second antenna 202 ;

[0108] and / or,

[0109] The antenna module 10 further includes a third feeding circuit 102 connected to the third feeding port of the second radiator structure 30 - 2 and the antenna ground 101 , and a fourth feeding circuit 103 connected to the fourth feeding port of the third radiator structure 30 - 3 and the antenna ground 101 ;

[0110] When the antenna unit 20 is the first communication module that transmits and receives wireless signals of the corresponding frequency band, the third feeding circuit 102 and the fourth feeding circuit 103 can respectively excite the second radiator structure 30-2 and the third radiator structure 30-3 to radiate wireless signals to assist the antenna unit 20 in transmitting and receiving wireless signals;

[0111] When the antenna unit 20 receives and transmits wireless signals of the corresponding frequency band for the second communication module, the third feeding circuit 102 does not provide an excitation signal to the second radiator structure 30-2, and the fourth feeding circuit 103 does not provide an excitation signal to the third radiator structure 30-3.

[0112] It should be noted that the first radiator structure 30 - 1 is a fixed radiator structure that plays an isolating role, and therefore the first radiator structure 30 - 1 is fixedly connected to the antenna ground 101 and does not switch its working mode with the use mode.

[0113] The second radiator structure 30 - 2 and the third radiator structure 30 - 3 will switch their working modes between isolating wireless signals and transmitting and receiving wireless signals according to the usage mode, and the switching can be specifically controlled by the third feeding circuit 102 and the fourth feeding circuit 103 .

[0114] Taking the third feed circuit 102 as an example, in the use mode corresponding to the first communication module, the second radiator structure 30-2 participates in the transmission and reception of signals. At this time, the third feed circuit 102 will excite the second radiator structure 30-2 to radiate wireless signals, for example, provide an excitation signal / excitation current to the second radiator structure 30-2 to assist the first antenna 201 and the second antenna 202 in transmitting and receiving signals; in the mode corresponding to the second communication module, the second radiator structure 30-2 does not participate in the transmission and reception of signals, and plays the role of isolating signals. At this time, the third feed circuit 102 will not excite the second radiator structure 30-2, so that it is in an isolated state as an isolation structure between the first antenna 201 and the second antenna 202. The fourth feed circuit 103 is similar, and will not be described here. Moreover, in other embodiments, the second radiator structure 30-2 is combined with the first radiator structure 30-1 and the third radiator structure 30-3 to form a series equivalent capacitor and a parallel equivalent inductor, thereby having a resonant frequency in the target frequency band, such as having the characteristics of negative dielectric constant and negative magnetic permeability at 2.4 GHz, thereby forming a metamaterial structure array that can block / offset the propagation of surface / space coupled waves of the wireless signals radiated by the first antenna 201 and the second antenna 202.

[0115] like Figure 2 As shown, only a simple schematic diagram of the third feeding circuit 102 and the fourth feeding circuit 103 is shown, which is mainly used to indicate the connection between the feeding circuit and the corresponding radiator structure 30. The second radiator structure 30-2 has a third feeding port as a connection end between the second radiator structure 30-2 and the third feeding circuit 102; the third radiator structure 30-3 has a fourth feeding port as a connection end between the third radiator structure 30-3 and the fourth feeding circuit 103.

[0116] It should also be noted that in Figure 2 In the example, each radiator structure 30 is an inverted F structure. Figure 3 As shown, the radiator structure 30 includes a long branch 301 and two short branches, the two short branches are respectively a first short branch 302 and a second short branch 303. The long branch 301 extends along a first direction, and the short branch extends along a second direction, the first direction and the second direction intersect, and in the drawings, the first direction and the second direction are perpendicular to each other as an example.

[0117] Among them, for the first radiator structure 30-1, both short branches have one end connected to the long branch 301 and the other end connected to the antenna ground 101. For the second radiator structure 30-2 and the third radiator structure 30-3, one end of the first short branch 302 is connected to the long branch 301 and the other end is connected to the antenna ground 101, and one end of the second short branch 303 is connected to the long branch 301 and the other end is connected to the corresponding feeding circuit (third feeding circuit 102 or fourth feeding circuit 103) as a feeding port (third feeding port or fourth feeding port). The length of the radiator structure 30 can be Figure 3 The 33 mm shown may also be other sizes in combination with the requirements of the electronic equipment, frequency band, power, etc. in actual application, and there is no specific limitation on this.

[0118] It should also be noted that Figure 3 The structure of the radiator structure 30 shown is only a schematic diagram, and the actual structure is not limited thereto.

[0119] Furthermore, if Figure 4 As shown, in some embodiments, the first antenna 201 further includes a first auxiliary branch 2013 which is connectable and disconnectable to the first radiation body 2011;

[0120] In the mode where the antenna unit 20 is used by the first communication module, the first radiation body 2011 is connected to the first auxiliary branch 2013. At this time, in the first antenna 201, the first radiation body 2011 and the first auxiliary branch 2013 together form an antenna structure for transmitting and receiving signals, and the first feeding circuit 2012 provides an excitation current to the first radiation body 2011 and the first auxiliary branch 2013;

[0121] In the mode where the antenna unit 20 is used by the second communication module, the first radiation body 2011 is disconnected from the first auxiliary branch 2013. At this time, in the first antenna 201, only the first radiation body 2011 transmits and receives signals, the first auxiliary branch 2013 does not participate in transmitting and receiving signals, and the first feeding circuit 2012 only provides an excitation current to the first radiation body 2011.

[0122] and / or,

[0123] The second antenna 202 further includes a second auxiliary branch 2023 which is connectable and disconnectable to the second radiation body 2021;

[0124] In the mode where the antenna unit 20 is used by the first communication module, the second radiation body 2021 is connected to the second radiation branch 2023. At this time, in the second antenna 202, the second radiation body 2021 and the second auxiliary branch 2023 together form an antenna structure for transmitting and receiving signals, and the second feeding circuit 2022 provides an excitation current to the second radiation body 2021 and the second auxiliary branch 2023;

[0125] When the antenna unit 20 is used by the second communication module, the second radiating body 2021 is disconnected from the second auxiliary branch 2023. At this time, in the second antenna 202, only the second radiating body 2021 is used to send and receive signals, the second auxiliary branch 2023 does not participate in sending and receiving signals, and the second feeding circuit 2022 only provides excitation current to the second radiating body 2021.

[0126] It should be noted that one or both of the first antenna 201 and the second antenna 202 may also include auxiliary branches. Figure 4 As shown, the example in which both the first antenna 201 and the second antenna 202 include auxiliary branches is taken. In a usage mode with high gain requirements (such as a satellite communication mode), the length of the antenna is increased due to the addition of the auxiliary branches, so that the antenna has a higher beamforming capability, thereby improving its gain. In a usage mode with relatively low gain requirements (such as a WLAN communication mode), there is no need to access the auxiliary branches, thereby reducing the path length of the antenna and adjusting the operating frequency.

[0127] To achieve the connection or disconnection between the radiating body and the auxiliary branches of the antenna in different modes, such as Figure 4 As shown, the first antenna 201 may also include a first switch 2014 for controlling the connection or disconnection between the first radiating body 2011 and the first auxiliary branch 2013, and / or the second antenna 202 may also include a second switch 2024 for controlling the connection or disconnection between the second radiating body 2021 and the second auxiliary branch 2023.

[0128] Here, the first switch 2014 and the second switch 2024 can both be diodes, triodes or other types of electronic switches. It can be controlled by a control signal. For example, the first switch 2014 and the second switch 2024 both receive the control signal. The corresponding antenna unit 20 is used by the first communication module. The control signal is in an enabled state. The first switch 2014 and the second switch 2024 are both turned on to connect the corresponding radiation body and the auxiliary branch. The corresponding antenna unit 20 is used by the second communication module. The control signal is in a non-enabled state. The first switch 2014 and the second switch 2024 are both disconnected, and the corresponding radiation body and the auxiliary branch are disconnected. In this way, by disconnecting or connecting the switch, the resonant frequency of the antenna is adjusted to make it work in the satellite communication mode or the WLAN communication mode. Corresponding to the case of more usage modes, different values ​​of the control signal can also be set to correspond to different modes.

[0129] In some embodiments, there is a third spacing between the phase center of the second radiator structure 30-2 and the phase center of the first radiating body 2011 of the first antenna 201, and there is a fourth spacing between the phase center of the third radiator structure 30-3 and the phase center of the second radiating body 2021 of the second antenna 202, and the third spacing and the fourth spacing are the same.

[0130] It should be noted that the spacing of the phase centers of the antennas will affect the coupling between the antennas. The phase center spacing can be used to calculate the phase difference. If the phase difference is too large, it will cause grating lobes to appear in the antenna pattern, resulting in energy dispersion and a decrease in the main lobe gain. If the phase difference is too small, the near-field interaction between the antennas will be enhanced, and the electromagnetic coupling between the antennas will change each other's input impedance, affecting the matching network. At the same time, part of the energy may be absorbed or reflected by the adjacent antenna, reducing the radiation efficiency. Therefore, it is necessary to ensure that the phase difference is neither too large nor too small, but in a moderate position. Usually, when the spacing of the phase centers is about half the signal wavelength, the beamforming efficiency is high, the main lobe of the antenna pattern is sharp, and the side lobes are controllable, so that the best radiation effect can be achieved. Therefore, in the embodiment of the present disclosure, the third spacing and the fourth spacing can both be half (or nearby) of the signal wavelength to ensure the best radiation effect.

[0131] In some embodiments, Figure 5 As shown, the first radiation body 2011 includes: a first branch 2015 extending along the first direction, a second branch 2016 and a third branch 2017 extending along the second direction; one end of the second branch 2016 is connected to the first branch 2015, the other end of the second branch 2016 is connected to the antenna ground 101, one end of the third branch 2017 is connected to the first branch 2015, and the other end of the third branch 2017 is connected to the first feeding circuit 2012 as the first feeding port of the first radiation body 2011; one end of the first branch 2015 is connected to the first auxiliary branch 2013 in an on-off manner; the length of the first branch 2015 is greater than the second branch 2016 and the third branch 2017;

[0132] and / or,

[0133] The second radiating body 2021 includes: a fourth branch 2025 extending along the first direction, a fifth branch 2026 and a sixth branch 2027 extending along the second direction; one end of the fifth branch 2026 is connected to the fourth branch 2025, and the other end of the fifth branch 2026 is connected to the antenna ground 101, one end of the sixth branch 2027 is connected to the fourth branch 2025, and the other end of the sixth branch 2027 is connected to the second feeding circuit 2022 as the second feeding port of the second radiating body 2021; one end of the fourth branch 2025 is connectable and disconnectable to the second auxiliary branch 2023; the length of the fourth branch 2025 is greater than that of the fifth branch 2026 and the sixth branch 2027.

[0134] It should be noted that the second branch 2016 in the first antenna 201 and the fifth branch 2026 in the second antenna 202 are both connected to the antenna ground 101, so the second branch 2016 and the fifth branch 2026 can be recorded as grounding branches; the third branch 2017 in the first antenna 201 and the sixth branch 2027 in the second antenna 202 are both connected to the corresponding feeding circuit, so the third branch 2017 and the sixth branch 2027 can be recorded as feeding branches.

[0135] like Figure 5 As shown, the first radiation body 2011 and the second radiation body 2021 can both be antennas of an "inverted F" structure, which has a compact structure and high radiation efficiency, and is suitable for use in miniaturized electronic devices. Exemplarily, the length of the radiation body in the first antenna 201 and the second antenna 202 can be 28 mm, and the length of the auxiliary branch can be 5 mm. Other sizes can also be used in combination with the requirements of the electronic equipment, frequency band, power, etc., which are not specifically limited.

[0136] In some embodiments, the structural parameters of the first radiating body 2011 of the first antenna 201, the first radiating body structure 30-1, the second radiating body structure 30-2, the third radiating body structure 30-3, and the second radiating body 2021 of the second antenna 202 are the same, or at least one of the first radiating body structure 30-1, the second radiating body structure 30-2, and the third radiating body structure 30-3 is different from the structural parameters of the first radiating body 2011 and the second radiating body 2021.

[0137] It should be noted that the structural parameters may include the antenna structure type. For example, in the accompanying drawings, the first antenna 201, the second antenna 202, and the radiator structure 30 are all "inverted F" antenna structures. In other examples, the antenna structures of the first antenna 201, the second antenna 202, and the radiator structure 30 may also be other structural types, which may be the same or different.

[0138] The structural parameters may also include operating frequency, bandwidth, impedance, standing wave ratio, gain, polarization mode, size, material, weight, beam width, power capacity, phase center, etc. It should also be noted that the first antenna 201, the second antenna 202 and each radiator structure 30 may all be conductive materials such as metal materials, such as copper, aluminum, iron, titanium, etc., or may also be polymer materials, composite materials, etc., and may be reasonably set according to actual needs.

[0139] exist Figure 4 On the basis of Figure 6 It shows a logic block diagram of the antenna module 10 working in different usage modes. Figure 7 is a schematic diagram of the state of the antenna module 10 in the satellite communication mode, Figure 8 : is a schematic diagram of the state of the antenna module 10 in the WLAN communication mode, assuming that the radiation body and the auxiliary branch are connected by a diode. Figure 6 and Figure 7 As shown, in the satellite communication mode, the diodes connected to the auxiliary branches in the first antenna 201 and the second antenna 202 are turned on. The first antenna 201 and the second antenna 202 are used as auxiliary excitation units, and a larger antenna aperture is formed by diode conduction. At the same time, the feeding of the second radiator structure 30-2 and the third radiator structure 30-3 is enabled, and the excitation current is provided by the third feeding circuit 102 and the fourth feeding circuit 103 respectively. The second radiator structure 30-2 and the third radiator structure 30-3 are used as antennas in the satellite communication frequency band. The first radiator structure 30-1 is used as an isolation branch to improve the performance of the satellite communication antenna. The first antenna 201, the second antenna 202, the second radiator structure 30-2 and the third radiator structure 30-3 perform power synthesis to improve the satellite communication gain.

[0140] It can be seen that in the mode where the antenna unit 20 is used by the first communication module (for example, a satellite communication module), the first antenna 201, the second radiator structure 30-2, the third radiator structure 30-3 and the second antenna 202 form a phased array to form the radiation pattern required by the first communication module after power synthesis in space. The corresponding signal field strength distribution can be as follows Fig. 9 shown.

[0141] like Figure 6 and Figure 8As shown, in the WLAN communication mode, the diode connecting the auxiliary branch of the first antenna 201 and the second antenna is disconnected. The feeding of the second radiator structure 30-2 and the third radiator structure 30-3 is disconnected (i.e., no power is supplied), and the third feeding circuit 102 and the fourth feeding circuit 103 do not provide excitation current. The first radiator structure 30-1, the second radiator structure 30-2 and the third radiator structure 30-3 act as isolation branches to improve the performance of the WLAN antenna. The corresponding signal field strength distribution can be as follows Fig.10 shown.
