摘要

本文通过在原结构上方放置寄生贴片来提高圆极化天线阵列的轴比带宽。以2×2圆极化贴片天线阵列为参考。在17 GHz和60 GHz中心频率下进行了仿真，结果表明:轴比带宽在17 GHz时从6.7%增加到16.7%，在60 GHz时从7.6%增加到19.1%。

Extending axial ratio bandwidth of antenna array by parasitic patches

In the paper, axial ratio bandwidth of a circularly polarized antenna array is increased by parasitic patches placed above the original structure. A 2×2 circularly polarized patch antenna array was used as a reference. Performed simulations at center frequencies 17 GHz and 60 GHz show correspondence: the axial ratio bandwidth was increased from 6.7% to 16.7% at 17 GHz, and from 7.6% to 19.1% at 60 GHz.
