摘要

本文采用非对称fin型设计了微带方形贴片阵列天线。通过刻蚀fin型结构，在接地面上产生缺陷，并利用优化后的贴片与缺陷之间的气隙进行分析。它可以在不影响共极化辐射方向图和输入阻抗的情况下实现对交叉极化的实质性抑制。采用fin型DGS结构的1×2阵列，隔离度提高19dB。

Cross Polarization Reduction in Patch Antenna Using DGS

In this paper, microstrip square patch array antenna is designed using an asymmetric FIN-type. FIN-type structure is etched to create defects in the ground plane and analyze with an optimized air gap between patch and defect. It is used to achieve substantial suppression of cross-polarization, without affecting the co-polarized radiation pattern and input impedance. A 1×2 array unified with FIN-type DGS structure showing the 19dB enhancement of isolation.
