A High-Gain Dual-Polarized Antenna

A differentially-driven dual-polarized high-gain stacked patch antenna is presented in this paper. Three-layer stacked patches are adopted to increase the impedance bandwidth of the antenna. Each of the three stacked patches are inserted with four shorting posts for enhancing the antenna gain. A wide band and a high isolation can be realized. Moreover, the antenna possesses the gain of as high as 11 dBi by the proposed design mechanism.
