摘要

本文提出了一种用于K和Ka双频双圆极化的四端口馈电网络。馈电网络由一个低频3dB桥、一个高频3dB桥和两个双工器组成。双工器在频带内的回波损耗优于30dB，隔离优于100dB，直接提高了整个网络的性能。最终馈电网络驻波比达到1.2，隔离度达到110dB。

Design of Dual Band and Dual Circular Polarization Feed Network

In this paper, a four-port feed network for K and Ka dual frequency and dual circular polarization is proposed. The feed network consists of a low frequency 3dB bridge, a high frequency 3dB bridge and two diplexers. The return loss of diplexer in band is better than 30dB, and the isolation is better than 100dB, which directly improves the performance of the whole network. The standing wave (VSWR) of the final feed network reaches 1.2 and the isolation reaches 110dB.
