Gain enhanced linear polarization switchable microstrip array antenna

Abstract

In this paper, the linear polarization switchable patch array antenna is proposed and the characteristics of the antenna are investigated by FDTD method and experimentally. By using four parasitic patched around the fed patch, the gain of the antenna can be increased to remarkable value of 12dBi. And also by changing the polarity of the bias voltage, the main polarization angle switching of the array antenna can be possible.
