Wideband dual-polarized antenna radiation unit and antenna thereof

The utility model provides a wideband dual-polarized antenna radiation unit, which is suitable for the field of a mobile communication base station antenna. The wideband dual-polarized antenna radiation unit comprises an integrally molded radiator, two pairs of balancers and a chassis. The radiator comprises two pairs of arrays which are orthogonally and symmetrically arranged; the two pairs of balancers are respectively corresponding to the two pairs of arrays; each array is connected with the chassis through the corresponding balancer; each balancer possesses a three-segment broken line form; and one end of the top of each balancer is provided with a feed connection protruding platform. The radiation unit is advantageous in that the gain is high, the cross polarization characteristic is good, the radiation convergence is good, when a double-frequency composite unit is formed, the influence on a high frequency oscillator is small, the mechanical property is strong, the structure is reliable, and process and production are easy. The utility model a wideband antenna applying the radiation unit simultaneously, the cross polarization characteristic of the antenna is good, the radiation convergence is good, the electrical property consistency is good, the structure is reliable, and large batch production is suitable.
