Embodiment
The present invention will be further described with specific embodiment below in conjunction with the accompanying drawings：A kind of as shown in figure 1, polarized rotation side
To backtracking array, including M polarized rotation direction backtracking subelement 1, M roads power splitter 2, local vibration source 3；Described M be more than etc.
In 3 integer；Subelement is recalled by double-fed dual-polarized patch antenna and phase conjugation frequency mixer in described polarized rotation direction
Composition；Described double-fed paster antenna is linked together with phase conjugation frequency mixer by two isometric first radio frequency electrical cables；
Described phase conjugation frequency mixer is prepared on same medium substrate with M roads power splitter, uses thickness here as 0.508mm's
F4B sheet materials；Described local vibration source is connected to the input port of M roads power splitter by the second radio frequency electrical cable.Described phase is total to
Two radio-frequency filters 52 that yoke frequency mixer 5 is printed on medium substrate 51 by medium substrate 51, three-dB coupler 53, phase are prolonged
Slow line 54, local oscillator filter 55, matching minor matters 56, two RF coaxial ports 57, diode pairs 58 form；Described phase is total to
Yoke mixes twice that the local frequency of device 5 is rf frequency, and IF-FRE is identical with rf frequency；Described its length of delay line phase 54
For a quarter radio frequency wavelength, physical length 20；Each RF coaxial port 57, radio-frequency filter 52 and three-dB coupler 53
Placed using the microstrip line connection of equal length and Central Symmetry.Described radio-frequency filter 52 is by two asymmetric Hes of tap 521
Two bending resonators 522 are formed, and tap position is apart from resonator edge 2mm；Two C-shapeds are provided with bending resonator 522
Groove 523, the size of C-channel 523 make one of radio-frequency filter 52 to fall with outer zero point in local frequency by appropriate adjustment.
The present invention principle be：Phase conjugation frequency mixer as shown in Figure 2, one shares 4 ports, and port 1 and port 2 are divided
Two ports of paster antenna are not connected with isometric coaxial line.When port 1, input phase isSignal when, by rf filtering
Enter three-dB coupler afterwards.Wherein all the way signal by the straight-through end of three-dB coupler again after delay line phase, using phase asIt is loaded on first diode；Another way is by the coupled end of three-dB coupler equally with phaseLoading
Onto second diode.Because two diode reverses are placed, in the phase by being mixed latter two diode output signal
ForWithSignal is respectively outputted to 1 and 2 port by delay line phase all the way, signal phase at two ports
Position is respectivelyWithAnother way signal is directly output to 1 and 2 port, signal phase point by three-dB coupler
It is notWithAs the above analysis when 1 port input radio frequency signal, in 1 port by two diodes
The intermediate-freuqncy signal of output is reversely offset；Intermediate-freuqncy signal in-phase stacking its phase exported in 2 ports by two diodes isAnalyze after the same method, when 2 port input radio frequency signal, in being exported in 1 port by two diodes
Its phase of frequency signal in-phase stacking isIn the anti-phase counteracting of intermediate-freuqncy signal that 2 ports are exported by two diodes；Also
It is to say when 1 port input radio frequency signal to only have 2 ports to export intermediate-freuqncy signal there was only 1 end when 2 port input radio frequency signal
Mouth can export intermediate-freuqncy signal, while it is known that the two intermediate-freuqncy signals have, 180 ° of proper phase is poor by analysis above, this
Outer intermediate-freuqncy signal and radiofrequency signal phase conjugation.Due to the phase gradient on the characteristic of phase conjugation therefore each antenna element and come
The phase gradient contrast that ripple is formed, direction backtracking then occurs.When incidence wave is vertically polarized wave, port 1 and port 2
Be respectively received equiphase radiofrequency signal, by conjugation be mixed after exported respectively by port 2 and port 1, the two signals by
The outside radiation level polarized wave of horizontal polarization electric current is therefore formed on paster in there is 180 ° of phase difference；When incidence wave is 45 °
During linea angulata polarized wave, only port 1 receives radiofrequency signal, and is exported by port 2, therefore the line polarization wave of radiation -45° angle；
When incidence wave is horizontal polarized wave, port 1 and port 2 receive constant-amplitude signal but its phase difference differs 180 °, mixed by being conjugated
Wherein 180 ° of phase differences of signal are compensated all the way after frequency, and two phase of output signal are identical, therefore radiate vertically polarized wave；It is right
Cross for circularly polarised wave and simply rotate said process, therefore the circularly polarised wave orthogonal with incoming wave can be radiated.By
Radiate orthogonally polarized wave in each unit, thus recall array radiation and and incoming wave polarization orthogonal ripple.
