Description

A kind of dual-polarization omnidirectional antenna

Technical field

The utility model belongs to the mobile communication equipment technical field, especially relates to a kind of dual-polarization omnidirectional antenna.

Background technology

In the 4G communication, use dual polarized antenna can improve network coverage quality, in indoor covering system, omnidirectional radiation double antenna technology realizes more difficult, implementation is too complicated and make cost relatively high; Existing dual polarized antenna horizontal polarization is partly used 5 unit oscillator circle distribution on same PCB face, increased greatly the PCB area, manufacturing cost is higher, horizontal polarization part power splitter is partly used the Wilson's power divider structure, but odd branches exists power division not wait separation structure, so in realization with on performance larger difficulty is arranged, and the PCB area that uses of power splitter is that this is novel more than 10 times, and also novel used power splitter not as good as this of performance.

Summary of the invention

The purpose of this utility model be to improve the deficiency of prior art and provide that a kind of cost is low, signal covering quality is high, the feeding network loss is little, the port phase difference and amplitude difference little and be convenient to the dual-polarization omnidirectional antenna of controlling.

The purpose of this utility model is like this, a kind of dual-polarization omnidirectional antenna, by outer cover, perpendicular polarization fine taper oscillator, the large taper oscillator of perpendicular polarization, horizontal radiation oscillator, Ba Lun, base plate, horizontal polarization feeding network and connector, formed, be characterized in that a plurality of independently horizontal radiation oscillators are distributed in around the large taper oscillator of perpendicular polarization circumference, each horizontal radiation oscillator is connected and fixed by Ba Lun and the large taper oscillator of perpendicular polarization, and the Ba Lun of a plurality of independently horizontal radiation oscillators horizontal polarization feeding network common with is connected.

In order further to realize the purpose of this utility model, can be that the horizontal polarization feeding network is inlayed and is arranged in base plate.

Compared with the prior art the utility model has following distinguishing feature and good effect: the utility model is that a plurality of independently horizontal radiation oscillators are distributed in around the large taper oscillator of perpendicular polarization circumference, each horizontal radiation oscillator is connected and fixed by Ba Lun and the large taper oscillator of perpendicular polarization separately, horizontal polarization is partly used and is loaded the realization of symmetrical dipole cloth annular array homophase constant amplitude feed, owing to using the split design, antenna Ba Lun can realize self-supporting simultaneously, thereby the great like this usable floor area that has reduced copper-clad plate is cost-saving, the quantity of horizontal radiation oscillator can be arranged as required, the general 3-8 that adopts is individual, the horizontal polarization feeding network is inlayed and is arranged in base plate, the horizontal polarization feeding network is embedded in the installation screw rod endoporus of base plate, convenient wiring, the Ba Lun of a plurality of independently horizontal radiation oscillators horizontal polarization feeding network common with is connected, the direct impedance conversion scheme of using feeding network realizes that 1:N (N is determined by oscillator quantity) impedance transformation completes coupling, it is little that this structure takies the PCB area, insertion loss is low, power division is even, phase equalization is high, simple in structure, the utility model perpendicular polarization is partly used the optimization biconical antenna, it has the broadband properties of biconical antenna, can be better than 1.5 by nearly 4 octave standing internal waves, and make it keep radiation characteristic preferably in working band through optimizing, the low 30 degree left and right of the more common biconical antenna of radiation rake angle, thereby it can have larger area coverage in signal covers engineering, the utility model adopts minute constant amplitude feeds such as direct impedance transform method realization simultaneously, and traditional method is used the Wilson's power divider structure, the utlity model has following advantage with respect to traditional structure: 1, reduce PCB area savings cost, 2, Miniaturization Design, be convenient to install in antenna, 3, the feeding network loss is little, and port phase difference and amplitude difference urine are in control.
