The beneficial effects of the utility model are that: the design degree of difficulty, the also production degree of difficulty and cost is reduced, the polarization that changes circular polarized antenna through the connection that changes wide band electric bridge and dual polarized antenna revolve to, as long as two input port of exchange wide band electric bridge and dual polarized antenna connection, just can be with the polarization of circular polarization soon to changing right hand circular polarization into by the left -hand circular polarization.
Description
Technical field
This utility model belongs to mobile communication network technology field, more particularly, to a kind of wide band circularly polarized antenna.
Background technology
The antenna of mobile communication base station system is typically all covered using ± 45 ° of dual polarized antenna, referred to as at present
For polarity diversity, it is also simplest MIMO technology.Antenna sends the signal of+45 ° and -45 ° of two linear polarizations simultaneously, receives sky
No matter line is+45 °, -45 ° of polarization or vertical or mean pole, can with less polarization mismatch receive base station signal (otherwise
As the same, that is, handset emissions base station receives similarly).This technology makes cellie grip mobile phone towards different directions
When, preferable polarization can be had to mate with base station；But, most of circular polarized antenna narrower bandwidth at present, general relative bandwidth<
10% it is impossible to the covering meeting 2G, 3G and 4G requires.
The signal of interference base station wanted by jammer, then the interference signal of transmitting also requires that electromagnetism wave energy simultaneously acts on difference
Grip the mobile phone (antenna for mobile phone polarization grips direction with mobile phone and changes) in direction.According to the feature of antenna, choose sending out of circular polarisation
Penetrating antenna is our optimal choice, but present market does not have the wide band circularly polarized antenna that we need.In order to solve jammer
Antenna problem, this patent provide a kind of antenna, the circular polarisation of achievable broad frequency band, 2G, 3G and 4G frequency range can be covered simultaneously,
It is mainly used in jammer antenna.
Content of the invention
The purpose of this utility model is to overcome the shortcomings of that prior art exists, and provides one kind to be mainly used in jammer
Wide band circularly polarized antenna on antenna.
The purpose of this utility model to complete by following technical solution, this wide band circularly polarized antenna, including double
Poliarizing antenna and wideband electrical bridge, described dual polarized antenna is provided with input, connects a wideband electrical bridge by this input；Should
Two linear polarization oscillators in dual polarized antenna are connected with input respectively.Two linear polarization oscillators of dual polarized antenna are in wideband
Power 2 decile and 90 ° of differences of phase place are met so that ± 45 ° of dual polarized antenna synthesis give off circular polarisation electromagnetic wave in band.
Preferably, described dual polarized antenna is provided with two inputs, respectively first input end and the second input
End, when first input end is located on the second input, polarization rotation direction is left-hand circular polarization；When the second input is located at first
When on input, polarization rotation direction is right-handed circular polarization.
The beneficial effects of the utility model are：Reduce design difficulty, also reduce production difficulty and reduce cost；
Change the polarization rotation direction of circular polarized antenna by the connection changing wideband electrical bridge and dual polarized antenna, as long as exchanging wideband electrical bridge
Two input ports connecting with dual polarized antenna are it is possible to be changed to dextrorotation circle by the polarization rotation direction of circular polarisation by left-hand circular polarization
Polarization, vice versa.
Brief description
Fig. 1 is structural representation Fig. 1 of the present utility model.
Fig. 2 is structural representation Fig. 2 of the present utility model.
Label in accompanying drawing is respectively：1st, dual polarized antenna；2nd, wideband electrical bridge；11st, linear polarization oscillator；12nd, the first input
End；13rd, the second input.
Specific embodiment
Below in conjunction with accompanying drawing, this utility model is done with detailed introduction：As shown in Figure 1, this utility model include bipolar
Change antenna 1 and wideband electrical bridge 2, described dual polarized antenna 1 is provided with input, a wideband electrical bridge 2 is connected by this input；
Two linear polarization oscillators 11 in this dual polarized antenna 1 are connected with input respectively；Two linear polarization oscillators of dual polarized antenna 1
11 meet power 2 decile and 90 ° of differences of phase place so that ± 45 ° of dual polarized antenna synthesis give off circular polarisation electricity in broadband
Magnetic wave, the difference according to wiring can produce left-handed or dextrorotation circularly polarised wave.
As shown in Fig. 2 described dual polarized antenna 1 is provided with two inputs, respectively first input end 12 and second
Input 13, when first input end 12 is located on the second input 13, polarization rotation direction is left-hand circular polarization；When the second input
When end 13 is located on first input end 12, polarization rotation direction is right-handed circular polarization；As long as exchanging wideband electrical bridge 2 and dual polarized antenna
1 connection two input ports it is possible to the polarization rotation direction of circular polarisation is changed to right-handed circular polarization by left-hand circular polarization, otherwise also
So.
This utility model is not limited to above-mentioned embodiment, no matter making any change on its shape or material are constituted, all
It is using structure design provided by the utility model, be all a kind of deformation of the present utility model, be all considered as new in this practicality
Within type protection domain.
