Ka频段高通量卫星地面关口站13m天线馈源系统设计

Design of a Feed System for 13m Gateway Antennas of Ka-Band High-Throughput Satellite Communication Systems

本文介绍了新一代高通量卫星通信系统下,13m Ka频段地面关口站天线馈源系统的设计实例。经过开发设计,得到一款高性能、免调试、模块化的天线馈源系统,具有良好的驻波、轴比、损耗、隔离特性。文末给出天线系统和馈源网络的实测结果,该天馈系统目前在全球Ka频段关口站系统中投入使用达30余台套,由于优良的电气和结构性能,深受用户好评。

In this paper,a feed system is designed for 13m gateway antennas of new generation high-throughput Ka-band satellite communication systems.The designed antenna feed system features high performance,adjustment free,and modular design.In addition,it has good standing wave,axial ratio,loss,and isolation performance.Finally,the measured results of the antenna system and the feed network are provided.More than 30 such antenna feed systems have been put into use in Ka-band gateways around the world.They have been well received by the users because of their good electrical and structural properties.
