摘要

我们研究了三个方形天线，以增加圆极化的带宽。每个天线都有两个相邻的角，使用垂直于地平面的分支馈线以相同的振幅和 90° 的相位差进行激励。我们使用矩法评估了 3 dB 轴向比带宽与环臂宽度的函数关系。结果发现，环臂宽度为 0.04 波长时，轴向比带宽达到 38%，比线环天线宽 3 倍。模拟结果得到了实验结果的验证。

A Simultaneous Study on Wire-Loop, Plate-Loop, and Plate Antennas for Wideband Circular Polarization

We investigate three square-shaped antennas to increase the bandwidth of circular polarization. Each antenna has two adjacent corners excited with the same amplitudes and a phase difference of 90° using a branched feedline vertical to the ground plane. We evaluate the 3 dB axial ratio bandwidth as a function of the loop-arm width using the moment method. It is found that the axial ratio bandwidth reaches 38% for an arm width of 0.04 wavelengths, wider than that of a wire-loop antenna by a factor of three. The simulated results are verified by experimental ones.
