[0002] Satellite communication is a wireless communication mode using a satellite as a relay station. In satellite communication, there are two working modes of electromagnetic waves, linear polarization and circular polarization. Circular polarization can greatly avoid the influence of multipath effect and the influence of some media in the atmospheric environment on the polarization rotation of electromagnetic waves.

[0003] In the related art, a circularly polarized antenna only has good circular polarization performance in a very small angle domain (generally near the maximum radiation direction). For directions deviating from the angle domain, the circular polarization performance becomes worse as the deviation angle increases. For mobile electronic devices, the circularly polarized antenna cannot adapt to all postures of the electronic device due to the changeable posture of the electronic device, thereby affecting the communication quality of the electronic device.

[0052] The following will be described in detail Figures 1 to 19 The antenna system 100, the control method of the antenna system 100, the control device of the antenna system 100, the electronic device and the readable storage medium according to the embodiments of the present application are described.

[0053] As Figures 1 to 6 As shown in the figure, the present application provides an antenna system 100, comprising: an antenna assembly 110, the antenna assembly 110 comprising a first antenna arm 112, a second antenna arm 114 and a third antenna arm 116, the first antenna arm 112 and the second antenna arm 114 being perpendicular, the first antenna arm 112 and the third antenna arm 116 being perpendicular, and the second antenna arm 114 and the third antenna arm 116 being perpendicular; a phase shift assembly 120, the phase shift assembly 120 comprising at least two phase shifters 128, at least two of the first antenna arm 112, the second antenna arm 114 and the third antenna arm 116 being connected to different phase shifters 128 respectively, so that the first antenna arm 112 and the second antenna arm 114 form circularly polarized radiation or elliptically polarized radiation when working, the first antenna arm 112 and the third antenna arm 116 form circularly polarized radiation or elliptically polarized radiation when working, and the second antenna arm 114 and the third antenna arm 116 form circularly polarized radiation or elliptically polarized radiation when working.

[0054] In the embodiments of the present application, the antenna system 100 comprises an antenna assembly 110 and a phase shift assembly 120, wherein the antenna assembly 110 comprises a first antenna arm 112, a second antenna arm 114 and a third antenna arm 116, any two of which are in perpendicular relationship, so that the first antenna arm 112 and the second antenna arm 114 are in the same plane, the third antenna arm 116 is perpendicular to the plane, the second antenna arm 114 and the third antenna arm 116 are in the same plane, the first antenna arm 112 is perpendicular to the plane, the first antenna arm 112 and the third antenna arm 116 are in the same plane, the second antenna arm 114 is perpendicular to the plane, and the phase shift assembly 120 is used to adjust the phase of the current flowing into the antenna assembly 110.

[0055] Specifically, the phase shift assembly 120 includes at least two phase shifters 128, wherein at least two of the first antenna arm 112, the second antenna arm 114 and the third antenna arm 116 are connected with one phase shifter 128 respectively, and the adjustment of the phase shifter 128 to the current phase can make the first antenna arm 112 and the second antenna arm 114 form circularly polarized radiation or elliptically polarized radiation, that is, the first antenna arm 112 and the second antenna arm 114 form a group of circularly polarized antennas or elliptically polarized antennas, the first antenna arm 112 and the third antenna arm 116 form circularly polarized radiation or elliptically polarized radiation, that is, the first antenna arm 112 and the third antenna arm 116 form a group of circularly polarized antennas or elliptically polarized antennas, the second antenna arm 114 and the third antenna arm 116 form circularly polarized radiation or elliptically polarized radiation, that is, the second antenna arm 114 and the third antenna arm 116 form a group of circularly polarized antennas or elliptically polarized antennas, and the radiation range of the three groups of circularly polarized antennas or elliptically polarized antennas covers the entire space, so that at least one group of circularly polarized antennas or elliptically polarized antennas has a radiation range suitable for forming communication with a signal source such as a satellite regardless of the posture of the antenna system 100, thereby improving the radiation range of the antenna system 100, and it is suitable for mobile electronic devices 200, that is, regardless of the posture of the electronic device 200, the antenna system 100 can provide better communication quality for the electronic device 200.

[0056] In addition, since there are three groups of circularly polarized antennas or elliptically polarized antennas in the present application, and the maximum radiation directions of the three groups of circularly polarized antennas or elliptically polarized antennas are perpendicular to each other, any two groups of circularly polarized antennas or elliptically polarized antennas have overlapping radiation ranges, thereby avoiding the problem of large deviation angle domain, solving the problem of small angle domain of circularly polarized antennas, specifically, if the angle domain of a group of circularly polarized antennas or elliptically polarized antennas deviates greatly, the angle domain of the other group of circularly polarized antennas or elliptically polarized antennas deviates relatively small, or falls within the angle domain of the other group of circularly polarized antennas or elliptically polarized antennas, thereby improving the angle domain of the entire antenna system 100, so that different circularly polarized antennas or elliptically polarized antennas are applied for different postures of the antenna system 100, thereby effectively improving the communication quality of the antenna system 100, and after the antenna system 100 is applied in the electronic device 200, the antenna system 100 can provide better communication quality regardless of the posture of the electronic device 200.

[0057] It should be noted that due to errors and objective conditions, the verticality of the first antenna arm 112 and the second antenna arm 114, the verticality of the first antenna arm 112 and the third antenna arm 116, and the verticality of the second antenna arm 114 and the third antenna arm 116 can be approximately vertical, which can have errors at a certain angle, for example: ±5 degrees, ±4 degrees, ±3 degrees, ±2 degrees or ±1 degree error.

[0058] The first antenna arm 112, the second antenna arm 114 and the third antenna arm 116 can be monopole antennas, Inverted-F Antennas (IFA antennas) or helical antennas, etc. The first antenna arm 112, the second antenna arm 114 and the third antenna arm 116 can be of the same type or different types.

[0059] As shown in the figure, Figures 7 to 11 The first antenna arm 112 corresponds to the x-axis, the second antenna arm 114 corresponds to the z-axis, and the third antenna arm 116 corresponds to the y-axis.

[0060] As shown in the figure, Figure 7 and Figure 8 The feeding positions of the first antenna arm 112, the second antenna arm 114 and the third antenna arm 116 are close to each other, that is, the first feeding point 1120 on the first antenna arm 112 is close to the second antenna arm 114 and the third antenna arm 116, the second feeding point 1140 on the second antenna arm 114 is close to the first antenna arm 112 and the third antenna arm 116, and the third feeding point 1160 on the third antenna arm 116 is close to the first antenna arm 112 and the second antenna arm 114. That is, the first feeding point 1120, the second feeding point 1140 and the third feeding point 1160 are adjacent, the three antenna arms can be of the same antenna form, work in the same mode, and the feeding positions are adjacent to each other. For example, the first antenna arm 112, the second antenna arm 114 and the third antenna arm 116 are all in the form of monopole antennas, all work in the 1 / 4 wavelength mode, and the feeding positions are all adjacent. When the antenna system 100 is applied to the electronic device 200, the first antenna arm 112, the second antenna arm 114 and the third antenna arm 116 of the antenna system 100 can extend from one corner of the device body 210 along three edges, and the feeding positions are all at the corner of the electronic device 200.

[0061] If only the first antenna arm 112 and the second antenna arm 114 work in the antenna system 100, the feeding phases of the first antenna arm 112 and the second antenna arm 114 can be made to differ by 90° through the phase shift assembly 120, so that the phases of the first antenna arm 112 and the second antenna arm 114 in the far field area also differ by 90°. Similarly, the same situation can occur between the second antenna arm 114 and the third antenna arm 116, and between the first antenna arm 112 and the third antenna arm 116. The phase difference of the currents in the two antenna arms in the circularly polarized antenna is 90°. If the phase difference of the currents in the two antenna arms is not 90°, an elliptically polarized antenna can be formed, which still retains certain circular polarization performance.

[0062] Optionally, the first antenna arm 112, the second antenna arm 114 and the third antenna arm 116 are fed by the same power supply assembly.

[0063] In addition, the at least two phase shifters 128 can be at least two of the first phase shifter 122, the second phase shifter 124 and the third phase shifter 126.

[0064] As a possible implementation, when the antenna system 100 is fed, the phase difference between the first antenna arm 112 and the second antenna arm 114 can be +90° or -90°, the phase difference between the first antenna arm 112 and the third antenna arm 116 can be +90° or -90°, and the phase difference between the second antenna arm 114 and the third antenna arm 116 can be +90° or -90°.

[0065] Specifically, when the antenna system 100 is fed, if the first antenna arm 112 and the second antenna arm 114 are working, the phase difference between the first antenna arm 112 and the second antenna arm 114 is +90° or -90°; if the first antenna arm 112 and the third antenna arm 116 are working, the phase difference between the first antenna arm 112 and the third antenna arm 116 is +90° or -90°; if the second antenna arm 114 and the third antenna arm 116 are working, the phase difference between the second antenna arm 114 and the third antenna arm 116 is +90° or -90°, so that the antenna assembly 110 can form a complete circularly polarized antenna, and the performance of the antenna system 100 is improved.

[0066] By adjusting the phase of the far-field region between two antenna arms to be +90° or -90°, it can be adjusted to work as left-handed circular polarization or right-handed circular polarization. For example, when the first antenna arm 112 and the second antenna arm 114 are working, as shown in FIG. 2, the phase of the far-field region of the first antenna arm 112 is controlled to be 90° ahead of the phase of the far-field region of the second antenna arm 114, so that they will form left-handed circularly polarized wave V in the +y direction and right-handed circularly polarized wave W in the -y direction; as shown in FIG. 3, the phase of the far-field region of the first antenna arm 112 is controlled to be 90° behind the phase of the far-field region of the second antenna arm 114, so that they will form right-handed circularly polarized wave W in the +y direction and left-handed circularly polarized wave V in the -y direction. Figure 9 Figure 10 As shown in FIG. 4, as a possible implementation, the phase shift assembly 120 includes two phase shifters 128, and when the antenna system 100 is fed, the phase difference between the first antenna arm 112 and the second antenna arm 114 can be +120° or -120°; or the phase difference between the first antenna arm 112 and the third antenna arm 116 can be +120° or -120°; or the phase difference between the second antenna arm 114 and the third antenna arm 116 can be +120° or -120°.

[0067] As shown in FIG. 4, as a possible implementation, the phase shift assembly 120 includes two phase shifters 128, and when the antenna system 100 is fed, the phase difference between the first antenna arm 112 and the second antenna arm 114 can be +120° or -120°; or the phase difference between the first antenna arm 112 and the third antenna arm 116 can be +120° or -120°; or the phase difference between the second antenna arm 114 and the third antenna arm 116 can be +120° or -120°. Figure 1

[0068] ​​Specifically, the phase shift assembly 120 includes two phase shifters 128, the first antenna arm 112 is electrically connected to the first phase shifter 122, the second antenna arm 114 is electrically connected to the second phase shifter 124, and the third antenna arm 116 is not connected to the phase shifter; or, the first antenna arm 112 is electrically connected to the first phase shifter 122, the third antenna arm 116 is electrically connected to the third phase shifter 126, and the second antenna arm 114 is not connected to the phase shifter; or, the second antenna arm 114 is electrically connected to the second phase shifter 124, the third antenna arm 116 is electrically connected to the third phase shifter 126, and the first antenna arm 112 is not connected to the phase shifter.

[0069] And, after the antenna system 100 is fed, the phase shifter 128 can be adjusted so that the phase difference between the current of the first antenna arm 112 and the current of the second antenna arm 114 is +120° or -120°, or so that the phase difference between the current of the first antenna arm 112 and the current of the third antenna arm 116 is +120° or -120°, or so that the phase difference between the current of the second antenna arm 114 and the current of the third antenna arm 116 is +120° or -120°. Since the phase difference is not +90° or -90°, the first antenna arm 112 and the second antenna arm 114 form elliptical polarization radiation, the first antenna arm 112 and the third antenna arm 116 form elliptical polarization radiation, and the second antenna arm 114 and the third antenna arm 116 form elliptical polarization radiation, which still retains certain circular polarization performance, and can achieve wide-angle circular polarization performance without switching the antenna arm of the antenna assembly 110.

[0070] That is, the first antenna arm 112 and the second antenna arm 114 can still form circular polarization performance in the y-axis and the surrounding angle domain, and the third antenna arm 116 will not affect the circular polarization performance in this direction, similarly, the first antenna arm 112 and the third antenna arm 116 can still form circular polarization performance in the z-axis and the surrounding angle domain, and the second antenna arm 114 will not affect the circular polarization performance in this direction, and the second antenna arm 114 and the third antenna arm 116 can still form circular polarization performance in the x-axis and the surrounding angle domain, and the first antenna arm 112 will not affect the circular polarization performance in this direction, that is, the antenna system 100 can form wide-angle circular polarization performance in the x-axis and the surrounding angle domain, the y-axis and the surrounding angle domain, and the z-axis and the surrounding angle domain at the same time, thereby improving the communication performance of the antenna system 100.

[0071] And, such a setting mode does not need to use elements such as the switching element 148, thereby reducing the cost, and avoiding the influence of the insertion loss of the switching element 148 and the like on the antenna performance.

[0072] Among them, as shown in Figure 7 The sizes of the first antenna arm 112, the second antenna arm 114, and the third antenna arm 116 are substantially the same.

[0073] As shown in Figure 6 , as a possible implementation, the phase shift component 120 includes three phase shifters 128, and the antenna system 100 further includes a power distribution component 130, the three phase shifters 128 and the power distribution component 130 are electrically connected, and the power distribution component is used to adjust the current amplitude of the first antenna arm 112, the second antenna arm 114 and the third antenna arm 116.

[0074] Specifically, the phase shift component 120 includes three phase shifters 128, that is, the first antenna arm 112 is electrically connected to the first phase shifter 122, the second antenna arm 114 is electrically connected to the second phase shifter 124, and the third antenna arm 116 is electrically connected to the third phase shifter 126, and the first phase shifter 122, the second phase shifter 124 and the third phase shifter 126 are all electrically connected to the power distribution component 130 and are electrically connected to the power supply component through the power distribution component 130.

[0075] The power distribution component 130 can adjust the power amplitude of the current on the first antenna arm 112, the second antenna arm 114 and the third antenna arm 116, so that the scanning of the circular polarization working area or the elliptical polarization working area can be realized by adjusting the power amplitude.

[0076] As shown in Figure 11 , when the electric field formed by the first antenna arm 112 and the second antenna arm 114 is equal in amplitude, and the phase difference of the current is 90°, at this time, better circular polarization performance radiation is formed in the D2 direction. If the power amplitude of the current of the second antenna arm 114 is increased, the direction of the circular polarization radiation will be deviated to the D1 direction and the D3 direction, and the D2 direction will become an elliptical polarization radiation with a larger axis. Through the orthogonal arrangement of the first antenna arm 112, the second antenna arm 114 and the third antenna arm 116 and the power distribution, a larger circular polarization radiation working area can be realized, a larger angle domain circular polarization performance can be realized, and the performance of the antenna system 100 is further improved. Wherein, the D2 direction can be the y-axis direction, and the D1 direction and the D3 direction form a certain angle on both sides of the y-axis direction.

[0077] As shown in Figure 6 and Figure 8 , as a possible implementation, the lengths of the first antenna arm 112, the second antenna arm 114 and the third antenna arm 116 are not equal.

[0078] Specifically, three conditions need to be met to form circular polarization radiation: first, the electric field components formed by two antenna arms are perpendicular; second, the electric field components formed by two antenna arms have a phase difference of 90°; third, the electric field components formed by two antenna arms are equal in amplitude.

[0079] Since the lengths of the first antenna arm 112, the second antenna arm 114 and the third antenna arm 116 are not equal, the three antenna arms cannot be fed with equal amplitudes, and the power distribution assembly 130 is needed to control the amplitudes of the currents on the three antenna arms, so as to control the amplitudes of the electric fields in the far field region.

[0080] When the sizes of some or one of the three antenna arms are greatly different from the sizes of the remaining antenna arms, for example, as shown in FIG. 1B, the size of the second antenna arm 114 is smaller, and it is difficult to make the current on the second antenna arm 114 consistent with the currents on the first antenna arm 112 and the third antenna arm 116, so the power distribution is needed to control the amplitudes of the currents on the three antenna arms, so that the amplitudes of the electric fields in the far field region are consistent, and thus better circular polarization performance can be obtained.

[0081] The same is true for the first antenna arm 112 and the third antenna arm 116.

[0082] When the antenna system 100 is applied to the electronic device 200, since the thickness of the electronic device 200 is usually thin, it is possible that the lengths of the three antenna arms cannot be equal, so the length of one or more of the antenna arms can be shortened to be shorter than the lengths of the other antenna arms. Therefore, by adjusting the amplitudes of the currents on the first antenna arm 112, the second antenna arm 114 and the third antenna arm 116 through the power distribution assembly 130, the first antenna arm 112 and the second antenna arm 114 can form circularly polarized radiation, the first antenna arm 112 and the third antenna arm 116 can form circularly polarized radiation, and the second antenna arm 114 and the third antenna arm 116 can form circularly polarized radiation.

[0083] As shown in FIG. 1C, as a possible implementation, the antenna system 100 further includes a switch assembly 140, the switch assembly 140 includes at least two switch elements 148, and at least two of the first antenna arm 112, the second antenna arm 114, the third antenna arm 116 and the at least two phase shifters 128 are electrically connected to the at least two switch elements 148 respectively, so as to control the states of the at least two of the first antenna arm 112, the second antenna arm 114 and the third antenna arm 116. Figures 2 to 5 Specifically, the antenna system 100 further includes the switch assembly 140, the switch assembly 140 includes at least two switch elements 148, and at least two of the first antenna arm 112, the second antenna arm 114 and the third antenna arm 116 are electrically connected to the at least two switch elements 148 respectively. The at least two switch elements 148 can be at least two of the first switch 142, the second switch 144 and the third switch 146.

[0084]

[0085] ​​The switch element 148 can be connected between the antenna arm and the power supply component, the switch element 148 can also be connected between the antenna arm and the power distribution component 130, the switch element 148 can also be connected between the phase shifter 128 and the power supply component, and the switch element 148 can also be connected between the phase shifter 128 and the power distribution component 130, thereby controlling the working state of the antenna arm, wherein the working state includes the working condition and the non-working condition.

[0086] For example, as shown in the feed network topology of the antenna system 100, Figure 2 The switch component 140 includes three switch elements 148, i.e. the first switch 142, the second switch 144 and the third switch 146, wherein the first antenna arm 112, the first phase shifter 122 and the first switch 142 are connected in series, the second antenna arm 114, the second phase shifter 124 and the second switch 144 are connected in series, the third antenna arm 116, the third phase shifter 126 and the third switch 146 are connected in series, and the first switch 142, the second switch 144 and the third switch 146 are connected in parallel on the power supply component. Among them, the far-field zone electric field phase difference of any two of the first antenna arm 112, the second antenna arm 114 and the third antenna arm 116 is +90° or -90°, thereby forming circularly polarized radiation.

[0087] Further, the working state of the three antenna arms can be controlled by the three switches. Specifically, when the antenna system 100 is fed, if the first switch 142 and the second switch 144 are closed and the third switch 146 is opened, the first antenna arm 112 and the second antenna arm 114 work, and the first phase shifter 122 and the second phase shifter 124 adjust the phase difference of the first antenna arm 112 and the second antenna arm 114 to form circularly polarized radiation in the y direction; if the second switch 144 and the third switch 146 are closed and the first switch 142 is opened, the second antenna arm 114 and the third antenna arm 116 work, and the second phase shifter 124 and the third phase shifter 126 adjust the phase difference of the second antenna arm 114 and the third antenna arm 116 to form circularly polarized radiation in the x direction; if the first switch 142 and the third switch 146 are closed and the second switch 144 is opened, the first antenna arm 112 and the third antenna arm 116 work, and the first phase shifter 122 and the third phase shifter 126 adjust the phase difference of the first antenna arm 112 and the third antenna arm 116 to form circularly polarized radiation in the z direction.

[0088] Therefore, by controlling the first switch 142, the second switch 144 and the third switch 146, the antenna system 100 can realize radiation in different directions, thereby reducing the mutual interference between the antenna arms and improving the performance of the antenna system 100.

[0089] Or, as shown in the feed network topology of the antenna system 100, Figure 3The feeding network topology of the shown antenna system 100, the switch assembly 140 includes three switch elements 148, namely the first switch 142, the second switch 144 and the third switch 146, wherein the first antenna arm 112 and the first switch 142 are connected in series, the second antenna arm 114, the second phase shifter 124 and the second switch 144 are connected in series, the third antenna arm 116, the third phase shifter 126 and the third switch 146 are connected in series, and the first switch 142, the second switch 144 and the third switch 146 are connected in parallel on the power supply assembly. Among them, the far-field zone electric field phase difference of any two of the first antenna arm 112, the second antenna arm 114 and the third antenna arm 116 is +90° or -90°, thereby forming circularly polarized radiation.

[0090] Further, the working of the three antenna arms can be controlled by the three switches. Specifically, when the antenna system 100 is fed from the back, if the first switch 142 and the second switch 144 are closed and the third switch 146 is open, the first antenna arm 112 and the second antenna arm 114 work, and the second phase shifter 124 adjusts the phase difference of the first antenna arm 112 and the second antenna arm 114 to form circularly polarized radiation in the y direction; if the second switch 144 and the third switch 146 are closed and the first switch 142 is open, the second antenna arm 114 and the third antenna arm 116 work, and the second phase shifter 124 and the third phase shifter 126 adjust the phase difference of the second antenna arm 114 and the third antenna arm 116 to form circularly polarized radiation in the x direction; if the first switch 142 and the third switch 146 are closed and the second switch 144 is open, the first antenna arm 112 and the third antenna arm 116 work, and the third phase shifter 126 adjusts the phase difference of the first antenna arm 112 and the third antenna arm 116 to form circularly polarized radiation in the z direction.

[0091] Therefore, by controlling the first switch 142, the second switch 144 and the third switch 146, the antenna system 100 can realize radiation in different directions, thereby reducing the mutual interference between the antenna arms and improving the performance of the antenna system 100. Moreover, one phase shifter 128 is omitted, saving cost.

[0092] Alternatively, as Figure 4The feeding network topology of the shown antenna system 100, the switch component 140 includes two switch elements 148, namely the second switch 144 and the third switch 146, wherein the first antenna arm 112 is directly connected to the power supply component, that is, the first antenna arm 112 is always in working state, the second antenna arm 114, the second phase shifter 124 and the second switch 144 are connected in series, the third antenna arm 116, the third phase shifter 126 and the third switch 146 are connected in series, and the first antenna arm 112, the second switch 144 and the third switch 146 are connected in parallel to the power supply component. Among them, the far-field zone electric field phase difference of any two of the first antenna arm 112, the second antenna arm 114 and the third antenna arm 116 is +90° or -90°, thereby forming circularly polarized radiation.

[0093] Further, whether the two antenna arms work or not can be controlled by the two switches. Specifically, when the antenna system 100 is fed from the back, if the second switch 144 is closed and the third switch 146 is opened, the first antenna arm 112 and the second antenna arm 114 work, and the second phase shifter 124 adjusts the phase difference of the first antenna arm 112 and the second antenna arm 114 to form circularly polarized radiation in the y direction; if the second switch 144 and the third switch 146 are closed, the first antenna arm 112, the second antenna arm 114 and the third antenna arm 116 work, and the second phase shifter 124 and the third phase shifter 126 adjust the phase difference of the second antenna arm 114 and the third antenna arm 116 to form circularly polarized radiation in the x direction, while the first antenna arm 112 also works, but the first antenna arm 112 is placed along the x axis and has basically no radiation in the x direction, so it will not affect the circularly polarized performance in the x direction; if the third switch 146 is closed and the second switch 144 is opened, the first antenna arm 112 and the third antenna arm 116 work, and the third phase shifter 126 adjusts the phase difference of the first antenna arm 112 and the third antenna arm 116 to form circularly polarized radiation in the z direction.

[0094] Therefore, by controlling the second switch 144 and the third switch 146, the antenna system 100 can realize radiation in different directions, thereby reducing the mutual interference between the antenna arms and improving the performance of the antenna system 100. Moreover, one phase shifter 128 and one switch element 148 are omitted, thereby saving cost.

[0095] Alternatively, as shown in FIG. 2, the switch component 140 includes three switch elements 148, namely the first switch 142, the second switch 144 and the third switch 146, wherein the first antenna arm 112 is directly connected to the power supply component, that is, the first antenna arm 112 is always in working state, the second antenna arm 114, the second phase shifter 124 and the second switch 144 are connected in series, the third antenna arm 116, the third phase shifter 126 and the third switch 146 are connected in series, and the first antenna arm 112, the second switch 144 and the third switch 146 are connected in parallel to the power supply component. Among them, the far-field zone electric field phase difference of any two of the first antenna arm 112, the second antenna arm 114 and the third antenna arm 116 is +90° or -90°, thereby forming circularly polarized radiation. Figure 5The antenna system 100 shown has a feed network topology where the switching assembly 140 includes two switching elements 148: a first switch 142 and a second switch 144. The first antenna arm 112 is electrically connected to the first switch 142. The second antenna arm 114, the second phase shifter 124, and the second switch 144 are connected in series. The third antenna arm 116 is electrically connected to the third phase shifter 126. The first switch 142, the second switch 144, and the third phase shifter 126 are connected in parallel to the power supply assembly, meaning the third antenna arm 116 is always operational. The far-field electric field phase difference between any two of the first antenna arms 112, the second antenna arm 114, and the third antenna arm 116 is +90° or -90°, thus forming circularly polarized radiation.

[0096] Furthermore, the operation of the two antenna arms can be controlled by two switches. Specifically, when the antenna system 100 is powered on, if the first switch 142 and the second switch 144 are closed, the first antenna arm 112, the second antenna arm 114, and the third antenna arm 116 will operate. The second phase shifter 124 adjusts the phase difference between the first antenna arm 112 and the second antenna arm 114, forming circularly polarized radiation in the y-direction. While the third antenna arm 116 also operates, it is positioned along the y-axis and has virtually no radiation in the y-direction, thus not affecting the circular polarization in the y-direction. Polarization performance: If the first switch 142 is open and the second switch 144 is closed, the second antenna arm 114 and the third antenna arm 116 operate, and the second phase shifter 124 and the third phase shifter 126 adjust the phase difference between the second antenna arm 114 and the third antenna arm 116 to form circularly polarized radiation in the x direction; if the first switch 142 is closed and the second switch 144 is open, the first antenna arm 112 and the third antenna arm 116 operate, and the third phase shifter 126 adjusts the phase difference between the first antenna arm 112 and the third antenna arm 116 to form circularly polarized radiation in the z direction.

[0097] Thus, by controlling the first switch 142 and the second switch 144, the antenna system 100 can radiate in different directions, thereby reducing mutual interference between antenna arms and improving the performance of the antenna system 100. Furthermore, one phase shifter 128 and one switching element 148 are omitted, saving costs.

[0098] like Figure 12 As shown, in one possible implementation, the antenna system 100 further includes: an attitude detection component 150 for detecting the attitude of the antenna assembly 110; and a controller 160 electrically connected to the attitude detection component 150, the switching component 140, and the phase shifting component 120, controlling the switching component 140 and the phase shifting component 120 according to the attitude of the antenna assembly 110. Specifically, the controller 160 is electrically connected to all the switching elements 148 and all the phase shifters 128.

[0099] Specifically, the antenna system 100 also includes an attitude detection component 150 and a controller 160. The attitude detection component 150 can detect the current attitude of the antenna component 110. The controller 160 is electrically connected to the attitude detection component 150, the switching component 140 and the phase shifting component 120, so that the controller 160 controls the switching component 140 and the phase shifting component 120 according to the current attitude of the antenna component 110.

[0100] The attitude detection component 150 can be a sensor such as a gyroscope, accelerometer, or electronic compass. When the antenna system 100 is applied to the electronic device 200, the attitude detection component 150 can be an attitude detection component shared with the electronic device 200, and the controller 160 can also be a processor shared with the electronic device 200.

[0101] Taking the application of antenna system 100 on electronic device 200 as an example, when attitude detection component 150 detects the current attitude of electronic device 200, the attitude of antenna system 100 can be determined based on the way antenna component 110 is installed on electronic device 200. Since the communication satellite is located in the sky, it is only necessary to search for signals in the radiation direction of the upper hemisphere of antenna component 110.

[0102] like Figure 15 As shown, in this posture, the electronic device 200 needs to switch the radiation direction of the antenna assembly 110 in a single direction of -z, -y and +x, thereby controlling the switching assembly 140 and the phase shifting assembly 120 to control the antenna assembly 110 to work in the above three directions in turn, and determine the best radiation direction of the signal as the working radiation direction. In the current state, it continues to work in the working radiation direction. The determination of signal strength includes the determination of polarization rotation.

[0103] The signal radiation direction is determined again only after the signal strength in that direction falls below the signal threshold.

[0104] Furthermore, left-hand circularly polarized satellite signals need to be received using left-hand circularly polarized operating mode, and right-hand circularly polarized satellite signals need to be received using right-hand circularly polarized operating mode. The determination of signal strength mentioned above includes radiation direction and polarization direction.

[0105] Specifically, Table 1 below shows the relationship between the radiation direction and polarization rotation of the switching assembly 140 and the phase shifting assembly 120 and the antenna assembly 110. The explanation is based on an example with a feed phase difference of +90° or -90°.

[0106] Table 1

[0107]

[0108] As shown in Table 1 above, after the controller 160 determines the attitude of the antenna assembly 110 through the attitude detection assembly 150, three axes towards the sky can be obtained, when radiation towards the +y direction is needed, the first antenna arm 112 and the second antenna arm 114 are controlled to work through the switch assembly 140, when left-handed circular polarization is needed, the phase difference between the first antenna arm 112 and the second antenna arm 114 is controlled to be +90° through the phase shift assembly 120, and when right-handed circular polarization is needed, the phase difference between the first antenna arm 112 and the second antenna arm 114 is controlled to be -90° through the phase shift assembly 120.

[0109] When radiation towards the -y direction is needed, the first antenna arm 112 and the second antenna arm 114 are controlled to work through the switch assembly 140, when left-handed circular polarization is needed, the phase difference between the first antenna arm 112 and the second antenna arm 114 is controlled to be -90° through the phase shift assembly 120, and when right-handed circular polarization is needed, the phase difference between the first antenna arm 112 and the second antenna arm 114 is controlled to be +90° through the phase shift assembly 120.

[0110] When radiation towards the +x direction is needed, the second antenna arm 114 and the third antenna arm 116 are controlled to work through the switch assembly 140, when left-handed circular polarization is needed, the phase difference between the second antenna arm 114 and the third antenna arm 116 is controlled to be +90° through the phase shift assembly 120, and when right-handed circular polarization is needed, the phase difference between the second antenna arm 114 and the third antenna arm 116 is controlled to be -90° through the phase shift assembly 120.

[0111] When radiation towards the -x direction is needed, the second antenna arm 114 and the third antenna arm 116 are controlled to work through the switch assembly 140, when left-handed circular polarization is needed, the phase difference between the second antenna arm 114 and the third antenna arm 116 is controlled to be -90° through the phase shift assembly 120, and when right-handed circular polarization is needed, the phase difference between the second antenna arm 114 and the third antenna arm 116 is controlled to be +90° through the phase shift assembly 120.

[0112] When radiation towards the +z direction is needed, the first antenna arm 112 and the third antenna arm 116 are controlled to work through the switch assembly 140, when left-handed circular polarization is needed, the phase difference between the first antenna arm 112 and the third antenna arm 116 is controlled to be +90° through the phase shift assembly 120, and when right-handed circular polarization is needed, the phase difference between the first antenna arm 112 and the third antenna arm 116 is controlled to be -90° through the phase shift assembly 120.

[0113] When radiation in the -z direction is needed, the first antenna arm 112 and the third antenna arm 116 are controlled to work by the switching assembly 140, when left-handed circular polarization is needed, the phase difference between the first antenna arm 112 and the third antenna arm 116 is controlled to be -90° by the phase shift assembly 120, and when right-handed circular polarization is needed, the phase difference between the first antenna arm 112 and the third antenna arm 116 is controlled to be +90° by the phase shift assembly 120.

[0114] As described above, when the first antenna arm 112, the second antenna arm 114 and the third antenna arm 116 are perpendicular to each other, and the phase is adjusted at the feeding point by the phase shift assembly 120, a wide-angle domain circular polarization performance can be formed in the x-axis and the surrounding angle domain, the y-axis and the surrounding angle domain, and the z-axis and the surrounding angle domain. Compared with the single angle domain circular polarization performance of the circular polarization antenna in the related art, the angle domain of the circular polarization performance of the embodiment is theoretically three times larger.

[0115] As described above, when the first antenna arm 112, the second antenna arm 114 and the third antenna arm 116 are perpendicular to each other, and the phase is adjusted at the feeding point by the phase shift assembly 120, a wide-angle domain circular polarization performance can be formed in the x-axis and the surrounding angle domain, the y-axis and the surrounding angle domain, and the z-axis and the surrounding angle domain. Compared with the single angle domain circular polarization performance of the circular polarization antenna in the related art, the angle domain of the circular polarization performance of the embodiment is theoretically three times larger. Figure 13 、 Figure 14 and Figure 15 The application provides an electronic device 200, which comprises the antenna system 100 provided in any of the above embodiments.

[0116] In the embodiments of the application, the electronic device 200 comprises the antenna system 100 provided in any of the above embodiments, and therefore has all the beneficial effects of the antenna system 100 provided in any of the above embodiments, which are not described one by one here.

[0117] The electronic device 200 can be a mobile phone, a tablet computer, a notebook computer, a palm computer, a vehicle-mounted electronic device 200, a mobile Internet device (MID), an augmented reality (AR) / virtual reality (VR) device, a robot, a wearable device, an ultra-mobile personal computer (UMPC), a netbook or a personal digital assistant (PDA), etc., and can also be a server, a network attached storage (NAS), a personal computer (PC), a television (TV), a teller machine or a self-service machine, etc.

[0118] Specifically, the electronic device 200 comprises a device body 210, the antenna system 100 is arranged inside the device body 210 and located at one top corner of the device body 210, the first antenna arm 112, the second antenna arm 114 and the third antenna arm 116 respectively extend along three adjacent sides of the device body 210, the control of the antenna system 100 and the processor of the electronic device 200 are shared, the pose detection component of the antenna system 100 and the pose detection component of the electronic device 200 are shared. The device body 210 comprises a screen component 220, and the screen component 220 can display and touch.

[0119] In some embodiments of the present application, a control method of an antenna system for an electronic device is provided, Figure 16 A flowchart of the control method of the antenna system according to the embodiments of the present application is shown as follows, Figure 16 As shown in the figure, the method comprises:

[0120] Step 1602: Obtain the pose of the antenna component;

[0121] Step 1604: Determine a plurality of radiation directions of the antenna component according to the pose of the antenna component;

[0122] Step 1606: Control the switch component and the phase shift component to work, so that the antenna component switches the radiation direction in the plurality of radiation directions in turn, and obtain the signal strength of the antenna component in different radiation directions;

[0123] Step 1608: Determine the radiation direction and the polarization rotation direction of the antenna component when working according to the signal strength.

[0124] The control method of the antenna system provided by the present application is used for the antenna system provided in the first aspect, the pose of the antenna component in the antenna system is obtained, and since the communication satellite is located in the sky, only the radiation direction of the upper hemisphere of the antenna component needs to be searched for signals. Then, based on the pose of the antenna component, a plurality of radiation directions capable of better communication with the communication satellite can be determined. Then, based on the plurality of radiation directions, the switch component and the phase shift component are controlled, so that the radiation direction of the antenna component works in the plurality of radiation directions respectively, and the signal strength in each radiation direction is obtained, the planned rotation direction is determined, the radiation direction with the best signal strength and the applicable polarization rotation direction is selected as the radiation direction when working, and the working state is continuously maintained, thereby improving the performance of the antenna system, not only the radiation range of the antenna system, but also the signal strength of the antenna system.

[0125] Until the signal strength is lower than the preset threshold value, the steps of the control method of the antenna system are performed again, and the working radiation direction and the polarization rotation direction are determined again.

[0126] The posture of the antenna assembly can be detected by the posture detection assembly. When the antenna system is applied to an electronic device, the posture detection assembly can be a posture detection assembly shared by the electronic device. The processor of the electronic device can execute the steps of the control method of the antenna system.

[0127] When the posture detection assembly detects the posture of the electronic device, the posture of the antenna system can be determined based on the manner in which the antenna assembly is mounted on the electronic device. Since the communication satellite is located in the sky, the signal needs to be searched only in the radiation direction of the upper hemisphere of the antenna assembly.

[0128] As shown in Figure 15 , the electronic device needs to switch the radiation direction of the antenna assembly in the -z direction, the -y direction, and the +x direction in the posture. Then, the switch assembly and the phase shift assembly are controlled, the antenna assembly is controlled to work in the above three directions in turn, and the best radiation direction of the signal is determined as the working radiation direction. In the current state, the working in the working radiation direction is continued. The determination of the signal strength includes the determination of the polarization rotation direction.

[0129] Until the signal strength in the direction is lower than the signal threshold, the determination of the working radiation direction of the signal is re-performed.

[0130] In addition, the left-handed circular polarized satellite signal needs to be received by using the left-handed circular polarized working mode, and the right-handed circular polarized satellite signal needs to be received by using the right-handed circular polarized working mode. The determination of the signal strength includes the radiation direction and the polarization rotation direction.

[0131] The relationship between the specific switch assembly and the phase shift assembly and the radiation direction and the polarization rotation direction of the antenna assembly is shown in Table 1. Here, it is not enumerated one by one.

[0132] The control method of the antenna system provided in the embodiments of the present application can be executed by the control device of the antenna system. In the embodiments of the present application, the control method of the antenna system is executed by the control device of the antenna system, and the control device of the antenna system provided in the embodiments of the present application is described.

[0133] As shown in Figure 17As shown, in some embodiments of the present application, a control device 1700 of an antenna system is provided for the antenna system provided in the first aspect, the control device 1700 of the antenna system comprises: a first acquisition module 1702 configured to acquire a posture of an antenna assembly; a first determination module 1704 configured to determine a plurality of radiation directions of the antenna assembly according to the posture of the antenna assembly; a second acquisition module 1706 configured to control a switch assembly and a phase shift assembly to work, so that the antenna assembly switches the radiation direction in the plurality of radiation directions in sequence, and acquires signal strengths of the antenna assembly in different radiation directions; and a second determination module 1708 configured to determine a radiation direction and a polarization handedness of the antenna assembly when working according to the signal strengths.

[0134] The control device of the antenna system provided in the present application is used for the antenna system provided in the first aspect, the posture of the antenna assembly in the antenna system is acquired, and since the communication satellite is located in the sky, only the radiation directions of the upper hemisphere of the antenna assembly need to be searched for signals. Then, based on the posture of the antenna assembly, the plurality of radiation directions capable of better communication with the communication satellite can be determined. Then, based on the plurality of radiation directions, the switch assembly and the phase shift assembly are controlled, so that the radiation direction of the antenna assembly works in the plurality of radiation directions respectively, and the signal strengths in each radiation direction are acquired, and the planned handedness is determined. The radiation direction with the best signal strength and the applicable polarization handedness is selected as the working radiation direction when working, and the working state is continuously maintained, so that the performance of the antenna system is improved, which is not limited to the radiation range of the antenna system, but also improves the signal strength of the antenna system.

[0135] Until the signal strength is lower than the preset threshold value, the control device of the antenna system is re-controlled, and the working radiation direction and the polarization handedness are re-determined.

[0136] The posture of the antenna assembly can be detected by a posture detection assembly. When the antenna system is applied to an electronic device, the posture detection assembly can be a posture detection assembly shared by the electronic device, and the control device of the antenna system can be a processor of the electronic device.

[0137] For example, when the posture detection assembly detects the posture of the current electronic device, the posture of the antenna system can be determined based on the manner in which the antenna assembly is installed on the electronic device. Since the communication satellite is located in the sky, only the radiation directions of the upper hemisphere of the antenna assembly need to be searched for signals.

[0138] For example, when the posture detection assembly detects the posture of the current electronic device, the posture of the antenna system can be determined based on the manner in which the antenna assembly is installed on the electronic device. Since the communication satellite is located in the sky, only the radiation directions of the upper hemisphere of the antenna assembly need to be searched for signals. Figure 15As shown, the electronic device needs to switch in the -z direction, -y direction and +x direction in the radiation direction of the antenna assembly in this posture, and further control the switch assembly and the phase shift assembly, control the antenna assembly to work in the above three directions in turn, and determine the best radiation direction of the signal as the working radiation direction. In the current state, the working in the working radiation direction is continuously carried out, wherein the determination of the signal strength includes the determination of the polarization rotation direction.
