The dual polarization vibrator improves the polarization detuning rate of the dual polarization antenna, and increases polarization detection rate of the dual polarization antenna.
Description
Technical field
The utility model relates to a kind of antenna oscillator, relates in particular to a kind of dual polarization oscillator that is used on the antenna for base station.
Background technology
Along with the development of mobile communication technology, more and more higher to the requirement of antenna for base station.Antenna for base station generally is combined into array format by the radiating element of same form, to obtain high gain.The radiating element of antenna for base station generally has two kinds of forms at present, and a kind of is the air microstrip aerial form, and a kind of is the oscillator form.The air microstrip aerial form has shortcomings such as narrow bandwidth, cross polarization be big; The antenna of oscillator form has the shortcoming that needs the balance conversion, and oscillator form antenna is departing from polarization resolution meeting variation, just polarization mismatch on the direction of greatest irradiation.
Summary of the invention
Technical problem to be solved of the present utility model: a kind of dual polarization oscillator that is applied on the antenna for base station is provided, and this dual polarization oscillator has improved the polarization mismatch rate of dual polarized antenna, increases the polarization resolution of dual polarized antenna.
The utility model solves the technical scheme that its technical problem adopts: a kind of dual polarization oscillator that is applied on the antenna for base station, it comprises two pairs of orthogonal dipoles, metal mounting panel, two feed metal hooks, every electrode couple is made up of the hook-type oscillator arms of the shape of falling L of two symmetries, the base portion of the hook-type oscillator arms of four shapes of falling L has footing, footing and metal mounting panel connect together, form direct-current short circuit, described two feed metal hooks respectively with described two electrode couple in pair of parallel.
Described feed metal hook connects feeding network and by on the insulating material fixing metal mounting panel, described feed metal hook is barb-like, two dipoles that the feed metal hook is fed energy to parallel respectively, the feed metal hook does not contact with dipole, dipole has been finished balance one uneven conversion by the feed of feed metal hook, and two feed metal hooks do not contact mutually.
Terminal curved curved downwards the prolonging of the hook-type oscillator arms horizontal component of the described shape of falling L.
The hook-type oscillator arms horizontal component end of the described shape of falling L is linearly curved downwards at a certain angle to be prolonged.
The beneficial effects of the utility model: terminal curved downwards the prolonging of the oscillator arms of dual polarization oscillator of the present utility model and metal mounting panel parallel portion, the part that forms barb has been improved the polarization mismatch characteristic of antenna, makes the cross polarization discrimination that reaches 10dB when greatest irradiation direction 60 is spent at least departing from.
