摘要
本文介绍了一种用于Ku频段卫星通信的双线极化天线馈源阵列,该馈源阵列可应用于单反射面或双反射面的卫星通信天线中,实现对通信卫星的小角度、高速、高精度电子波束扫描和跟踪,降低卫星天线对机械伺服结构精度和动态跟踪的要求,从而大幅降低伺服系统成本,拓展动中通卫星天线在民用领域的应用。
A dual polarized antenna feed array for Ku band satellite communications is introduced in this paper which can be applied to satcom antenna with single reflector or double reflector.Using the feed array can realize small angle,high speed and high accuracy electronic beam scanning and tracking for communication satellites.At the same time,it will reduce the requirements of both mechanical accuracy and dynamic tracking to servo structure and thereby greatly reducing the cost and expanding the application of satcom antenna in civil field.
