Ka波段圆极化平板阵列天线设计

本文设计了一种规模为 8×8 的 Ka 波段圆极化平板阵列天线。2×2 子阵为一个圆极化基本单元，子阵馈电方波导腔体中插入极化膜片形成圆极化特性，使用全并馈 E 面波导功分网络对 16 个子阵实现等幅同相馈电。设计的阵列天线实现了良好的圆极化特性与高增益特性。

Design of Ka-Band Circular Polarization Planar Slot Array Antenna

A Ka-band circular polarization planar array antenna with a scale of is 8×8 is designed in this paper, 2×2 subarray as a basic unit, its circular polarization characteristic is achieved by inserting polarized diaphragm into the subarray feed square waveguide. Using full-corporated E-plane power divider, the 16 subarrays are fed in the continuous phase. This way, the array antenna designed here fulfills good circular polarization and high gain feature.
