摘　　要：研制了1种工作于L/X/Ku/K a四频段的9 m天线馈源网络。天线在L频段(1.1〜1.7 GHz)具有左、右旋圆极化及双线极化功能,X频段(7〜9 GHz)具有双圆极化功能,Ku频段(10.95〜12.75 GHz)具有双线极化功能,Ka频段(17.7〜21.2 GHz)具有左、右旋圆极化及双线极化功能。着重论述馈源网络组成与工作原理以及X/Ku双频网络关键微波器件分波器、低通滤波器的设计,最后给出馈源网络的实测结果,完全满足项目指标要求。In this paper,a 9m antenna feed network operating in L/X/Ku/Ka four-band is developed.The antenna has the functions of left and right circular and dual-linear polarization in L-band(l.l〜1.7 GHz),dual-circular polarization in X-band(7~9 GHz),dual-linear polarization in Ku-band(10.95〜12.75 GHz),and left and right circular and dual-linear polarization in Ka-band(17.7-21.2 GHz).This paper focuses on the composition and working principle of feed network,and the key microwave devices of X/Ku dual-band network system,such as wave separator and low-pass filter are emphasized.Finally,the measured results of the feed network are given,which fully meet the requirements of the project.
