摘要：

A dual-polarized planar antenna with EBG backed structure fed by microstrip line is proposed. The backed EBG structure is tiled 45 degrees to enhance the isolation between the dual polarized antennas. From the simulated results, the antenna isolation can be improved from 10dB to better that 29dB. Also, the polarization isolation can be improved from 8dB to 18dB with mid ground added and the gain response is more stable as well. The antenna occupies an area of 5.3 X2 mm2 for millimeter wave (MMW) application. The planar design makes the antenna easy to integrate with RF circuitry on the same board, especially, in the MMW application.
