摘要

本文提出了一种通过改善近场相位分布来改善热-珀罗腔天线辐射方向图的有效方法。在feb - perot空腔天线上方放置一种称为相位校正结构(PCS)的印刷结构，通过改变PCS中金属片的大小来增强h平面上的相位均匀性。获得的相位均匀性还使天线的峰值指向性增加了5.6 dBi。

Directivity improvement of a Fabry-Perot cavity antenna by enhancing near field characteristic

This paper presents an effective technique for radiation patterns improvement of a Febry-Perot cavity antenna by improving the near field phase distribution. A printed structure named phase correcting structure (PCS) is placed above the Febry-Perot cavity antenna to enhance phase uniformity along the H-plane by varying the size of metallic patches in the PCS. The achieved phase uniformity also results in 5.6 dBi increase in the peak directivity of the antenna.
