Abstract :
A dual polarized patch antenna fed by meandering probes is presented. The antenna achieves an impedance bandwidth (SWR < 2) of 26% at each input port. By locating the meandering probes appropriately, the antenna has isolation more than 25 dB, which can be further enhanced to more than 30 dB by surrounding the antenna with vertical metallic walls. The gain of the antenna is about 10 dBi across the operating bandwidth.
