[0031] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0032] It should be noted that the cross-polarization of a phased array antenna needs to reach at least 30dB. If the cross-polarization specification is not met, the electromagnetic waves emitted by the phased array antenna will interfere with the normal operation of the satellite or the normal use of other user terminals. Currently, more and more mobile communication scenarios are using two-dimensional electronically scanned phased array antennas. In mobile communication scenarios, the state of the phased array antenna is constantly changing, and its cross-polarization is also constantly changing. When a conventional phased array antenna scans to a large off-axis angle, the cross-polarization of the phased array antenna will deteriorate severely. To meet the cross-polarization requirements of the system, conventional electronically scanned phased array antennas often optimize the cross-polarization of the passive antenna itself, which leads to high antenna design difficulty and makes it difficult to meet the cross-polarization specification across the entire coverage area.

[0033] To overcome the above problems, this application provides a fully polarized antenna control method applied to a terminal device. The terminal device includes at least a first polarization and a second polarization, and the terminal device can be a phased array antenna.

[0034] Please refer to Figure 1 , Figure 1 This is a flowchart illustrating the fully polarized antenna control method provided in an embodiment of this application. Figure 1 As shown, the fully polarized antenna control method includes S101 and S102.

[0035] S102, based on the first main polarization level, the first cross polarization level, the second main polarization level, the second cross polarization level, and the target polarization, determine the coefficient relationship between the first polarization and the second polarization.

[0036] Wherein, the first main polarization level is the main polarization level of the first polarization, the first cross polarization level is the cross polarization level of the first polarization, the second main polarization level is the main polarization level of the second polarization, and the second cross polarization level is the cross polarization level of the second polarization.

[0037] It should be noted that, compared to existing technologies that only consider the main polarization levels of the first and second polarizations when synthesizing linear or circular polarization, without considering the first and second cross-polarization levels, the cross-polarization of the antenna cannot be optimized. The coefficient relationship in this application is the relationship between the coefficients of the first and second polarizations. In determining the coefficient relationship, in addition to considering the first and second main polarization levels, the first and second cross-polarization levels are also fully considered.

[0038] S103, by adjusting the phase difference and amplitude ratio between the first polarization and the second polarization, the coefficient relationship is adapted to complete the target polarization fitting.

[0039] As mentioned above, in determining the coefficient relationship, this application embodiment considers not only the first and second main polarization levels, but also the first and second cross-polarization levels. By adjusting the phase difference and amplitude ratio between the first and second polarizations to adapt the coefficient relationship, the cross-polarization deterioration can be avoided while achieving target polarization fitting, thus ensuring the cross-polarization performance of the antenna.

[0040] In summary, this application provides a fully polarized antenna control method. Based on a first primary polarization level, a first cross-polarization level, a second primary polarization level, a second cross-polarization level, and a target polarization, the coefficient relationship between the first polarization and the second polarization is determined. Specifically, the first primary polarization level is the primary polarization level of the first polarization, the first cross-polarization level is the cross-polarization level of the first polarization, the second primary polarization level is the primary polarization level of the second polarization, and the second cross-polarization level is the cross-polarization level of the second polarization. When determining the coefficient relationship, in addition to considering the first and second primary polarization levels, the first and second cross-polarization levels are also fully considered. By adjusting the phase difference and amplitude ratio between the first and second polarizations, the coefficient relationship is adapted, which can avoid cross-polarization deterioration while achieving target polarization fitting, thus ensuring the antenna's cross-polarization performance.

[0041] In one possible implementation, the first polarization is horizontal, the second polarization is vertical, the target polarization is linear, and the first and second polarizations are orthogonal linear polarizations. Considering only the principal polarizations of the first and second polarizations, linear polarization synthesis can be achieved as follows. Specifically, the expression for the target polarization is:

[0042] E = e h H co +e v V co ;

[0043] It can be deduced that the polarization direction of the target polarization is related to the first and second main polarization levels:

[0044] angle = arctan(V) co / H co );

[0045] Among them, e h e represents the horizontal polarization component (first polarization component). v H represents the vertical polarization component (second polarization component). co Characterizing the first principal polarization level, V co The second main polarization level is represented by angle, the polarization direction of the target polarization is represented by angle, and E represents the target polarization.

[0046] Understandably, by adjusting H co Table and V co The ratio of [value] can achieve linear polarization in any polarization direction, also known as full polarization. However, this method does not consider the cross-polarization level of orthogonal line antennas, so the cross-polarization of the antenna cannot be optimal.

[0047] To overcome the above problems, this application also provides a possible implementation method for adapting the coefficient relationship, please refer to the following.

[0048] E = e h (A*H co +B*V cr )+e v (A*H cr +B*V co );

[0049] angle=arctan((A*H cr +B*V co ) / (A*H co +B*V cr ));

[0050] It can be derived that the expression for the coefficient relationship is:

[0051] B / A=(H co *tan(angle)-H cr ) / (V co -V cr *tan(angle));

[0052] By adjusting the phase difference and amplitude ratio between the first and second polarizations, the expression for adapting the coefficient relationship is as follows:

[0053] B / A = amp * exp(1j * phase);

[0054] Where A represents the coefficient of the first polarization, B represents the coefficient of the second polarization, B / A represents the coefficient relationship, and H... co H represents the first principal polarization level. cr Characterizing the first cross-polarization level, V co Characterizing the second principal polarization level, V cr The second cross-polarization level is represented by angle, the polarization direction of the target polarization is represented by angle, the amplitude ratio of the second polarization to the first polarization is represented by amp, the phase difference between the second polarization and the first polarization is represented by phase, j is the imaginary part of the complex number, and e is the number of polarizations. h e represents the horizontal polarization component (first polarization component). v denoted by , which represents the vertical polarization component (second polarization component), and E represents the target polarization.

[0055] In this embodiment, the cross-polarization performance of the antenna is improved by further adjusting the amplitude ratio and phase difference of vertical polarization and horizontal polarization using the tested main polarization level and cross-polarization level of vertical polarization and horizontal polarization.

[0056] In one possible implementation, the first polarization is a left-handed circular polarization, the second polarization is a right-handed circular polarization, and the target polarization is a linear polarization. Considering only the main polarizations of the first and second polarizations, the linear polarization synthesis can be achieved in the following way.

[0057] In left-hand circular polarization, the horizontal and vertical components must have equal amplitudes, and the phase difference between the vertical and horizontal components must be 90 degrees (corresponding to pi / 2 radians). The expression for the dominant polarization level is:

[0058] L co =e h H co1 +e v V co1 ;

[0059] The transformation yields:

[0060] L co =e h (amp1*exp(1j*ph1))+e v (amp1*exp(1j*(ph1+pi / 2))).

[0061] Here, amp1 represents the amplitude of the horizontal / vertical polarization, and ph1 represents the phase of the horizontal component.

[0062] In right-hand circular polarization, the horizontal and vertical components must have equal amplitudes, and the phase difference between the vertical and horizontal components must be -90 degrees (corresponding to -pi / 2 radians). The expression for the dominant polarization level is:

[0063] R co =e h H co2 +e v V co2 ;

[0064] The transformation yields:

[0065] R co =e h (amp2*exp(1j*ph2))+e v (amp2*exp(1j*(ph2-pi / 2))).

[0066] Here, amp2 represents the amplitude of the horizontal / vertical polarization, and ph2 represents the phase of the horizontal component.

[0067] In the process of circular polarization combining into linear polarization, the amplitude of left-hand circular polarization must be equal to the amplitude of right-hand circular polarization (i.e., amp1 = amp2).

[0068] E=L co +R co ;

[0069] =e h (H co1 +H co2 )+e v (V co1 +V co2 )

[0070] =e h (amp1*(exp(1j*ph1))+exp(1j*ph2)))+

[0071] e v (amp1*(exp(1j*(ph1+pi / 2)))+exp(1j*(ph1-pi / 2))));

[0072] The relationship between the polarization directions of the target polarization can be derived:

[0073] angle=arctan((exp(1j*(ph1+pi / 2)))+exp(1j*(ph1-pi / 2))) /

[0074] (exp(1j*ph1))+exp(1j*ph2)));

[0075] = (ph2-ph1) / 2;

[0076] Among them, e h e represents the horizontal component in circular polarization. v The vertical component in circular polarization, L co Characterizing the first polarization level, R co The second primary polarization level is represented by angle, the polarization direction of the target polarization is represented by angle, E represents the target polarization, and ph1 and ph2 represent the horizontal component phases in the first and second polarizations.

[0077] Understandably, the above formula does not take into account the cross-polarization level of the orthogonal circular antenna, and the cross-polarization performance of the antenna cannot reach the optimal level.

[0078] To overcome the above problems, when the first polarization is left-handed circular polarization, the second polarization is right-handed circular polarization, and the target polarization is linear polarization, this application embodiment also provides a possible implementation method for adapting the coefficient relationship, please refer to the following.

[0079] The expression for the target polarization is: E = A * L co +A*L cr +B*R co +B*R cr ;

[0080] Left-hand circular polarization level E L=A*L co +B*R cr ;

[0081] Right-hand circular polarization level E R =A*L cr +B*R co ;

[0082] Based on the requirements for the composite linear polarization of dual circular polarization, the amplitudes of the right-hand and left-hand circular polarizations must be equal, and a phase difference must exist. Therefore:

[0083] E R / E L =exp(1j*2*angle);

[0084] (A*L cr +B*R co ) / (A*L co +B*R cr ) = exp(1j*2*angle);

[0085] It can be derived that the expression for the coefficient relationship is:

[0086] B / A = (L co *exp(1j*2*angle)-L cr ) / (R co -R cr *exp(1j*2*angle));

[0087] By adjusting the phase difference and amplitude ratio between the first and second polarizations, the expression for adapting the coefficient relationship is as follows:

[0088] B / A = amp * exp(1j * phase);

[0089] Where A represents the coefficient of the first polarization, B represents the coefficient of the second polarization, B / A represents the coefficient relationship, and L co L represents the first primary polarization level. cr Characterizing the first cross-polarization level, R co Characterizing the second principal polarization level, R cr The second cross-polarization level is represented by angle, the polarization direction of the target polarization is represented by angle, the amplitude ratio of the second polarization to the first polarization is represented by amp, the phase difference between the second polarization and the first polarization is represented by phase, and j is the imaginary part of the complex number.

[0090] In this embodiment, the cross-polarization of the antenna is improved by further adjusting the amplitude ratio and phase difference of the right-hand circular polarization and the left-hand circular polarization, based on the tested main polarization and cross-polarization of the right-hand circular polarization and the left-hand circular polarization.

[0091] In one possible implementation, the first polarization is a left-handed circular polarization, the second polarization is a right-handed circular polarization, and the target polarization is a left-handed circular polarization. Considering only the main polarizations of the first and second polarizations, the synthesis of left-handed circular polarization can be achieved in the following way.

[0092] Specifically, left-hand circular polarization can be achieved by closing the second polarization channel (right-hand circular polarization channel). However, this method takes into account the cross-polarization of the first polarization itself. If the cross-polarization performance of the first polarization is poor, it will affect the use of the communication system.

[0093] To overcome the above problems, the first polarization is left-handed circular polarization, the second polarization is right-handed circular polarization, and the target polarization is left-handed circular polarization. Regarding how to adapt the coefficient relationship, this application embodiment also provides a possible implementation method, please refer to the following.

[0094] The expression for the target polarization is: E = B * R co +A*L cr +B*R cr +A*L co ;

[0095] To ensure good cross-polarization of left-hand circular polarization, the right-hand circular polarization component must be 0, which means that the following must be satisfied:

[0096] 0 = B*R co +A*L cr ;

[0097] It can be derived that the expression for the coefficient relationship is:

[0098] B / A = -L cr / R co

[0099] By adjusting the phase difference and amplitude ratio between the first and second polarizations, the expression for adapting the coefficient relationship is as follows:

[0100] B / A = amp * exp(1j * phase);

[0101] Where A represents the coefficient of the first polarization, B represents the coefficient of the second polarization, B / A represents the coefficient relationship, and L cr Characterizing the first cross-polarization level, R co The second primary polarization level is represented by amp, the amplitude ratio of the second polarization to the first polarization is represented by phase, and j is the imaginary part of the complex number.

[0102] Understandably, the cross-polarization performance of the antenna can be improved by additionally adjusting the amplitude ratio and phase difference between right-hand circular polarization and left-hand circular polarization.

[0103] In one possible implementation, the first polarization is a left-handed circular polarization, the second polarization is a right-handed circular polarization, and the target polarization is a right-handed circular polarization. Considering only the main polarizations of the first and second polarizations, the synthesis of right-handed circular polarization can be achieved in the following way.

[0104] Specifically, right-hand circular polarization can be achieved by closing the first polarization channel (left-hand circular polarization channel). However, this method takes into account the cross-polarization of the second polarization itself. If the cross-polarization performance of the second polarization is poor, it will affect the use of the communication system.

[0105] To overcome the above problems, the first polarization is left-handed circular polarization, the second polarization is right-handed circular polarization, and the target polarization is left-handed circular polarization. Regarding how to adapt the coefficient relationship, this application embodiment also provides a possible implementation method, please refer to the following.

[0106] The expression for the target polarization is: E = B * R co +A*L cr +B*R cr +A*L co ;

[0107] To ensure good cross-polarization of right-hand circular polarization, the left-hand circular polarization component must be 0, which means that the following must be satisfied:

[0108] 0 = B*R cr +A*L co ;

[0109] It can be derived that the expression for the coefficient relationship is:

[0110] B / A = -L co / R cr

[0111] By adjusting the phase difference and amplitude ratio between the first and second polarizations, the expression for adapting the coefficient relationship is as follows:

[0112] B / A = amp * exp(1j * phase);

[0113] Where A represents the coefficient of the first polarization, B represents the coefficient of the second polarization, B / A represents the coefficient relationship, and L co Characterizing the first primary polarization level, R cr The second cross-polarization level is represented by amp, the amplitude ratio of the second polarization to the first polarization is represented by phase, and j is the imaginary part of the complex number.

[0114] Understandably, the cross-polarization performance of the antenna can be improved by additionally adjusting the amplitude ratio and phase difference between right-hand circular polarization and left-hand circular polarization.

[0115] In one possible implementation, the first polarization is horizontal polarization, the second polarization is vertical polarization, and the target polarization is either left-handed or right-handed circular polarization. Considering only the primary polarizations of the first and second polarizations, the synthesis of left-handed or right-handed circular polarization can be achieved in the following manner.

[0116] Left-hand circular polarization requires that the horizontal and vertical components have equal amplitudes, and that the vertical and horizontal components have a 90-degree phase difference. The expression for the dominant polarization level is:

[0117] L = e h H co +e v V co ;

[0118] Right-hand circular polarization requires that the horizontal and vertical components have equal amplitudes, and the phase difference between the vertical and horizontal components is -90 degrees. The expression for the dominant polarization level is:

[0119] R = e h H co +e v V co ;

[0120] Among them, e h e represents the horizontal polarization component (first polarization component). v H represents the vertical polarization component (second polarization component). co Characterizing the first principal polarization level, V co The second primary polarization level is represented by L, which represents left-hand circular polarization, and R which represents right-hand circular polarization. co The amplitude is equal to V co The amplitude, left-hand circular polarization H co With V co The phase difference between them is -90 degrees, and the right-hand circularly polarized H co With V co The phase difference between them is 90 degrees.

[0121] Understandably, the above formula does not take into account the cross-polarization level of the orthogonal circular antenna, and the cross-polarization performance of the antenna cannot reach the optimal level.

[0122] To overcome the above problems, when the first polarization is horizontal, the second polarization is vertical, and the target polarization is left-handed or right-handed circular polarization, this application embodiment also provides a possible implementation method for adapting the coefficient relationship, please refer to the following.

[0123] H Z =A*H co +B*V cr ;

[0124] V Z =A*H cr +B*V co ;

[0125] L = e h H Z +e v V Z ;

[0126] R = e h H Z +e v V Z ;

[0127] Among them, e h e represents the horizontal polarization component (first polarization component). v H represents the vertical polarization component (second polarization component). co H represents the first principal polarization level. cr Characterizing the first cross-polarization level, V cr Characterizing the second cross-polarization level, V co The second primary polarization level is represented by L, which represents left-hand circular polarization, and R which represents right-hand circular polarization. Z Characterizing the total level of horizontal polarization, V Z A represents the total level of vertical polarization, A represents the coefficient of the first polarization, and B represents the coefficient of the second polarization.

[0128] Understandably, according to the definition of circular polarization, H needs to be satisfied. Z and V Z If the amplitudes are equal, then H is right-handed circularly polarized. Z Phase ahead of V Z 90 degrees phase (i.e., phase H) Z -V Z =90 degrees, complex expression written as 1j); if it is left-handed circular polarization, then H Z Phase lag V Z 90 degrees phase (i.e., phase H) Z -V Z = -90 degrees, complex number expression -1j).

[0129] According to the definition of left-hand circular polarization, V Z / H Z =1j;

[0130] (A*H cr +B*V co ) / (A*H co +B*V cr )=1j;

[0131] B / A=(Hcr -1j*H co ) / (1j*V cr -V co );

[0132] By adjusting the phase difference and amplitude ratio between the first and second polarizations, the expression for adapting the coefficient relationship is as follows:

[0133] B / A = amp * exp(1j * phase).

[0134] According to the definition of right-hand circular polarization, V Z / H Z =-1j;

[0135] (A*H cr +B*V co ) / (A*H co +B*V cr )=-1j;

[0136] B / A=(H cr +1j*H co ) / (-1j*V cr -V co );

[0137] By adjusting the phase difference and amplitude ratio between the first and second polarizations, the expression for adapting the coefficient relationship is as follows:

[0138] B / A = amp * exp(1j * phase).

[0139] Where A represents the coefficient of the first polarization, B represents the coefficient of the second polarization, B / A represents the coefficient relationship, and H... co H represents the first principal polarization level. cr Characterizing the first cross-polarization level, V co Characterizing the second principal polarization level, V cr The second cross-polarization level is represented by amp, the amplitude ratio of the second polarization to the first polarization is represented by phase, and j is the imaginary part of the complex number.

[0140] In this embodiment, the cross-polarization performance of the antenna is improved by further adjusting the amplitude ratio and phase difference of the vertical polarization and the horizontal circular polarization through the tested main polarization and cross polarization of vertical polarization and horizontal polarization.

[0141] exist Figure 1 Based on this, regarding how to obtain the first main polarization level, the first cross polarization level, the second main polarization level, and the second cross polarization level, embodiments of this application also provide a possible implementation method, please refer to...

Test the dominant polarization level H of the H-line polarization throughout the entire scan space. co and cross-polarization level H cr Then, the dominant polarization level V of the V-line polarization was tested throughout the scan space. co and cross-polarization level V cr .

[0144] It should be noted that H in the embodiments of this application co H cr V co V cr L co L cr R co and R cr All are plural numbers.

[0145] The fully polarized antenna control method provided in this application has the following characteristics. First, it is simple to implement and requires no specific performance parameters for the dual-polarized antenna. The main polarization and cross-polarization values ​​of the dual-polarized antenna are obtained through testing. Different polarization configurations can be set according to application requirements, improving the cross-polarization performance of antennas with poor cross-polarization. Second, it provides good cross-polarization performance. By introducing cross-polarization into polarization synthesis, the amplitude and phase ratio of the dual polarizations are calculated using a formula. Adjusting the amplitude and phase of the two polarizations yields optimal cross-polarization performance.

[0150] The adaptation unit 202 is used to adapt the coefficient relationship by adjusting the phase difference and amplitude ratio between the first polarization and the second polarization, thereby completing the target polarization fitting.

[0151] Optionally, the processing unit 201 may execute S102 as described above, and the adaptation unit 202 may execute S103 as described above.
