Dual polarized antenna 2 is antenna communication signal for horizontal polarization signals and the vertical polarization signal syntheses that will input from first antenna port 21 and the second antenna port 22 respectively.
Dual polarized antenna 2 is additionally operable to the antenna communication signal processing received becomes the horizontal polarization signals and vertical polarization signal that export from first antenna port 21 and the second antenna port 22 respectively.
Owing to the horizontal polarization signals of input or output is different with the amplitude of vertical polarization signal and phase contrast, thus synthesis and the antenna communication signal received can be left-handed or right-handed circular polarization signal, left-handed or Right-hand elliptical polarization signal, dual polarized signals or linear polarization signal.
It is described for antenna communication signal for circularly polarized signal below, during synthesis circularly polarized signal, electric bridge 1 is needed the radiofrequency signal inputted from one of the first electric bridge port 11 and the second electric bridge port 12 to be processed into respectively from the 3rd electric bridge port 13 and what the 4th electric bridge port 14 exported, amplitude is equal and phase contrast is 90 ° or-90 ° horizontal polarization signals and vertical polarization signal, and dual polarized antenna 2 is by respectively from first antenna port 21 and what the second antenna port 22 inputted, amplitude is equal and phase contrast is 90 ° or-90 ° horizontal polarization signals and vertical polarization signal syntheses are circularly polarized signal.
When receiving circularly polarized signal, the circularly polarized signal received is processed into respectively from first antenna port 21 and horizontal polarization signals that the second antenna port 22 exports, that amplitude is equal and phase contrast is 90 ° or-90 ° and vertical polarization signal by dual polarized antenna 2, and horizontal polarization signals that input from the 3rd electric bridge port 13 with the 4th electric bridge port 14 respectively, that amplitude is equal and phase contrast is 90 ° or-90 ° is become the radiofrequency signal from the output of one of the first electric bridge port 11 and the second electric bridge port 12 by electric bridge 1 with vertical polarization signal processing.
Specifically, with reference to shown in Fig. 1, electric bridge 1 for being processed into amplitude is equal and phase contrast is 90 ° horizontal polarization signals and vertical polarization signal and exporting from the 3rd electric bridge port 13 and the 4th electric bridge port 14 respectively by the first via radiofrequency signal inputted from the first electric bridge port 11, such as horizontal polarization signals exports from the 3rd electric bridge port 13, and vertical polarization signal exports from the 4th electric bridge port 14.
Owing to first antenna port 21 is connected with the 3rd electric bridge port 13, therefore dual polarized antenna 2 is inputted from the horizontal polarization signals of the 3rd electric bridge port 13 output through first antenna port 21, and owing to the second antenna port 22 is connected with the 4th electric bridge port 14, therefore from the 4th electric bridge port 14 output vertical polarization signal input dual polarized antenna 2 through the second antenna port 22, dual polarized antenna 2 by equal for the amplitude inputted from first antenna port 21 and the second antenna port 22 respectively and phase contrast be 90 ° synthesize right-handed circular polarization signal.
Correspondingly, dual polarized antenna 2 is for becoming amplitude equal the right-handed circular polarization signal processing received and horizontal polarization signals that phase contrast is-90 ° and vertical polarization signal, and horizontal polarization signals exports from first antenna port 21, vertical polarization signal exports from the second antenna port 22.

Thus the vertical polarization signal processing from the horizontal polarization signals of the 3rd electric bridge port 13 input and from the 4th electric bridge port 14 input becomes the first via radiofrequency signal from the first electric bridge port 11 output.
With reference to shown in Fig. 1, electric bridge 1 for being processed into amplitude is equal and phase contrast is-90 ° horizontal polarization signals and vertical polarization signal and exporting from the 3rd electric bridge port 13 and the 4th electric bridge port 14 respectively by the second tunnel radiofrequency signal inputted from the second electric bridge port 12, such as horizontal polarization signals exports from the 3rd electric bridge port 13, and vertical polarization signal exports from the 4th electric bridge port 14.
Owing to first antenna port 21 is connected with the 3rd electric bridge port 13, therefore dual polarized antenna 2 is inputted from the horizontal polarization signals of the 3rd electric bridge port 13 output through first antenna port 21, and owing to the second antenna port 22 is connected with the 4th electric bridge port 14, therefore from the 4th electric bridge port 14 output vertical polarization signal input dual polarized antenna 2 through the second antenna port 22, dual polarized antenna 2 by equal for the amplitude inputted from first antenna port 21 and the second antenna port 22 respectively and phase contrast be-90 ° synthesize left-hand circular polarization signal.
Correspondingly, dual polarized antenna 2 is for becoming amplitude equal the left-hand circular polarization signal processing received and horizontal polarization signals that phase contrast is 90 ° and vertical polarization signal, and horizontal polarization signals exports from first antenna port 21, vertical polarization signal exports from the second antenna port 22.

Thus the vertical polarization signal from the horizontal polarization signals of the 3rd electric bridge port 13 input and from the 4th electric bridge port 14 input is processed into the second tunnel radiofrequency signal exported from the second electric bridge port 12 by electric bridge 1.
In brief, synthesis circularly polarized signal, need electric bridge 1 output amplitude equal and the two-way vertical polarization signal of phase 90 ° or-90 ° and horizontal polarization signals, but synthesis elliptic polarization signal or synthetic thread polarized signal, electric bridge 1 exports that the amplitude of signal is not necessarily equal and phase also differs is decided to be 90 ° or-90 °.

It is used for some specific embodiments of the antenna module 100 of Beidou navigation mobile terminal test system according to the present invention referring to Fig. 1-Fig. 4 detailed description.
In one embodiment of the invention, the antenna module 100 for Beidou navigation mobile terminal test system includes electric bridge 1 and dual polarized antenna 2, and electric bridge 1 is 3dB90 ° of phase shift power splitter 1a, the thus low cost of manufacture of electric bridge 1. Dual polarized antenna 2 is dual polarization quadruple ridged horn antenna 2a. In other words, with reference to shown in Fig. 1, antenna module 100 can include the 3dB90 ° of phase shift power splitter 1a shown in dual polarization quadruple ridged horn antenna 2a and Fig. 2 shown in Fig. 3, and the first antenna port 21 of dual polarization quadruple ridged horn antenna 2a is connected with the 3rd electric bridge port 13 of 3dB90 ° of phase shift power splitter 1a, and second antenna port 22 of dual polarization quadruple ridged horn antenna 2a is connected with the 4th electric bridge port 14 of 3dB90 ° of phase shift power splitter 1a.
Specifically, as shown in Figure 2, in 3dB90 ° of phase shift power splitter 1a, first electric bridge port 11 is connected with the 3rd electric bridge port 13 and the 4th electric bridge port 14 respectively, second electric bridge port 12 is connected with the 3rd electric bridge port 13 and the 4th electric bridge port 14 respectively, and the isolation of the first electric bridge port 11 and the second electric bridge port 12 is high.
With reference to described in Fig. 2,3dB90 ° of phase shift power splitter 1a has two kinds of mode of operations:
1) Signal separator pattern
In this mode, first electric bridge port 11 accesses first via radiofrequency signal for input, second electric bridge port 12 is isolated, connect 50 ohm load, 3rd electric bridge port 13 and the 4th electric bridge port 14 are as outfan, and output amplitude is equal respectively and the horizontal polarization signals of phase-90 ° or vertical polarization signal.
In this mode, second electric bridge port 12 accesses the second tunnel radiofrequency signal for input, first electric bridge port 11 is isolated, connect 50 ohm load, 3rd electric bridge port 13 and the 4th electric bridge port 14 are as outfan, and output amplitude is equal respectively and the horizontal polarization signals of phase 90 ° or vertical polarization signal.
2) signal mixed model
In this mode, 3rd electric bridge port 13 and the 4th electric bridge port 14 are input and the amplitude that is respectively connected to is equal and the horizontal polarization signals of phase 90 ° or during vertical polarization signal, second electric bridge port 12 isolation connects 50 ohm load, first electric bridge port 11 exports first via radiofrequency signal for outfan, and signal intensity is the twice of the 3rd electric bridge port 13 or the 4th electric bridge port 14 signal intensity.
In this mode, 3rd electric bridge port 13 and the 4th electric bridge port 14 are input and the amplitude that is respectively connected to is equal and the horizontal polarization signals of phase-90 ° or during vertical polarization signal, first electric bridge port 11 isolation connects 50 ohm load, second electric bridge port 12 exports the second tunnel radiofrequency signal for outfan, and signal intensity is the twice of the 3rd electric bridge port 13 or the 4th electric bridge port 14 signal intensity.
The antenna module 100 for Beidou navigation mobile terminal test system actually used in, if dual polarized antenna 2 receives left-hand circular polarization signal, then dual polarized antenna 2 exports that two amplitudes are equal and the signal of phase contrast 90 °, process through electric bridge 1 just can obtain the signal of corresponding port (such as the first electric bridge port 11), the power of the signal of this corresponding port is two input signal power sums, and another one port (the second electric bridge port 12) signal is more weak, isolation is high;When dual polarized antenna 2 receives right-handed circular polarization signal, then dual polarized antenna 2 exports that two amplitudes are equal and the signal of phase contrast-90 °, process through electric bridge 1 just can obtain the signal of corresponding port (such as the second electric bridge port 12), the power of the signal of this corresponding port is two input signal power sums, and another one port (the first electric bridge port 11) signal is more weak, isolation is high.
As it is shown on figure 3, dual polarized antenna 2 can use again dual polarization VIVALDI antenna to substitute for dual polarization quadruple ridged horn antenna 2a, dual polarization quadruple ridged horn antenna 2a. Specifically, dual polarization quadruple ridged horn antenna 2a includes the vertical polarization portion 23a with two ridges and the horizontal polarization portion 24a with two ridges, vertical polarization portion 23a is connected with first antenna port 21, horizontal polarization portion 24a and the second antenna port 22 are connected, horizontal polarization portion 24a and vertical polarization portion 23a orthogonal space, say, that horizontal polarization portion 24a is positioned at the first plane, vertical polarization portion 23a is positioned at the second plane, and the first plane is orthogonal with the second plane.
If activating first antenna port 21 and the second antenna port 22 respectively, then dual polarization quadruple ridged horn antenna 2a can distinguish emission level polarized signal and vertical polarization signal, that is, if the second antenna port 22 input level polarized signal, horizontal polarization portion 24a emission level polarized signal, if first antenna port 21 inputs vertical polarization signal, vertical polarization portion 23a launches vertical polarization signal; Otherwise, if this dual polarization quadruple ridged horn antenna 2a receives vertical polarization signal or horizontal polarization signals, first antenna port 21 and the second antenna port 22 will export corresponding signal, that is, if horizontal polarization portion 24a receives horizontal polarization signals, then the second antenna port 22 output level polarized signal, if vertical polarization portion 23a receives vertical polarization signal, then first antenna port 21 exports vertical polarization signal.
If activate first antenna port 21 and the second antenna port 22 simultaneously, and phase place is identical, then dual polarization quadruple ridged horn antenna 2a launches dual-linear polarization signal, that is, if first antenna port 21 inputs the second antenna port 22 input level polarized signal while vertical polarization signal, then dual polarization quadruple ridged horn antenna 2a launches dual-linear polarization signal; Otherwise, if this dual polarization quadruple ridged horn antenna 2a receives dual polarized signals, then first antenna port 21 and the second antenna port 22 will export vertical polarization and horizontal polarization signals respectively, that is, if vertical polarization portion 23a receives vertical polarization signal while horizontal polarization portion 24a receives horizontal polarization signals, then first antenna port 21 exports vertical polarization signal and the second antenna port 22 output level polarized signal.
It is understandable that, in this embodiment, if inputting the second tunnel radiofrequency signal from the second electric bridge port 12, by equal for the amplitude that obtains the 3rd electric bridge port 13 and the 4th electric bridge port 14 exports and phase contrast 90 ° signal, dual polarization quadruple ridged horn antenna 2a will launch left-hand circular polarization signal; Accordingly, if inputting first via radiofrequency signal from the first electric bridge port 11, then dual polarization quadruple ridged horn antenna 2a will launch right-handed circular polarization signal.
If dual polarization quadruple ridged horn antenna 2a receives left-hand circular polarization signal, signal amplitude that then signal and second antenna port 22 of first antenna port 21 output exports and phase contrast-90 °, carrying out signal mixing by 3dB90 ° of phase shift power splitter 1a as shown in Figure 2, the second electric bridge port 12 can obtain reacting the output of left-hand circular polarization signal;Similar, if dual polarization quadruple ridged horn antenna 2a receives right-handed circular polarization signal, carrying out signal mixing by 3dB90 ° of phase shift power splitter 1a as shown in Figure 2, the first electric bridge port 11 can obtain reacting the output of right-handed circular polarization signal.

If activating first antenna port 21 and the second antenna port 22 respectively, then dual-polarized patch antenna 2b can launch vertical polarization signal and horizontal polarization signals respectively, that is, if first antenna port 21 inputs vertical polarization signal, first antenna unit 23b launches vertical polarization signal, if the second antenna port 22 input level polarized signal, the second antenna element 24b emission level polarized signal; Otherwise, if this dual-polarized patch antenna 2b receives vertical polarization signal or horizontal polarization signals, first antenna port 21 and the second antenna port 22 will export corresponding signal, that is, if first antenna unit 23b receives vertical polarization signal, then first antenna port 21 exports vertical polarization signal, if the second antenna element 24b receives horizontal polarization signals, then the second antenna port 22 output level polarized signal.
If activate first antenna port 21 and the second antenna port 22 simultaneously, and phase place is identical, then dual-polarized patch antenna 2b launches dual-linear polarization signal, that is, if first antenna port 21 inputs the second antenna port 22 input level polarized signal while vertical polarization signal, then dual-polarized patch antenna 2b launches dual-linear polarization signal; Otherwise, if this dual-polarized patch antenna 2b receives dual polarized signals, then first antenna port 21 and the second antenna port 22 will export vertical polarization and horizontal polarization signals respectively, that is, if the second antenna element 24b receives horizontal polarization signals while first antenna unit 23b receives vertical polarization signal, then first antenna port 21 exports vertical polarization signal and the second antenna port 22 output level polarized signal.
It is understandable that, in this embodiment, if inputting the second tunnel radiofrequency signal from the second electric bridge port 12, by equal for the amplitude that obtains the 3rd electric bridge port 13 and the 4th electric bridge port 14 exports and phase contrast 90 ° signal, dual-polarized patch antenna 2b will launch left-hand circular polarization signal;Accordingly, if inputting first via radiofrequency signal from the first electric bridge port 11, then dual-polarized patch antenna 2b will launch right-handed circular polarization signal.
