Abstract
In this paper, a novel broadband dual-polarized antenna with high-gain, high isolation based on antipodal Vivaldi antenna was introduced. The dual-polarized antenna structure is designed by two modified antipodal Vivaldi antennas (94mm*70mm*1.6mm) in a cross-shaped form. The simulation results show that the operating frequency band is from 1.8 GHz to 6 GHz when the S11 less than -10dB, and the gain of the antenna is more than 5dB. The isolation of the dual-polarization is less than -20dB. The proposed antenna can obtain wide impedance bandwidth, high port isolation, and simple structure. The dual-polarized antenna can be used for the base station communication.
