The dipole of traditional WCDMA dual-polarization antenna is very simple.Due to machining and inbalance of line feed,there is an inbalance of spatial radiation for dipole.Only depending on the dipole,the cross-polarization requirement cannot be obtained.Therefore,a kind of method with broadband dual-polarization antennas with 90 degrees is proposed:the special construction is applied in the end of radiation dipole.The symmetry of the antenna dipole is improved through adjusting the shape of connection const...
