摘要

本文研究了一种工作在w波段的紧凑型圆极化喇叭天线，该天线能产生具有宽阻抗带宽和3db轴比带宽的左手圆极化(LHCP)。与基于隔膜的CP天线相比，具有更好的功率处理能力和结构刚度。初步仿真结果表明，在75.7 GHz ~ 110 GHz范围内，在方向性为17±1.2 dBic的情况下，反射系数低于- 21 dB，轴比低于3 dB。

A W-band Compact Circularly Polarized Horn Antenna

This paper presents our study on a compact circular polarized horn antenna working in W-band which can generate Left Hand Circular Polarization (LHCP) with wide impedance bandwidth and 3-dB axial ratio bandwidth. And better power-handling capability and structure rigidity are also expected when compared with septum-based CP antennas. The preliminary simulation results show that the reflection coefficient below −21 dB and axial ratio below 3 dB from 75.7 GHz to 110 GHz can be achieved while the directivity is 17±1.2 dBic.
