摘要

扩展高斯-拉盖尔模式为分析波束波导系统提供了一种更精确、更简单的方法。利用BWGs因子的传播模式集和矩阵的乘法，可以推导出具有交叉极化场的输出场图。为卫星地面站天线设计了一种q波段(33-50 GHz)双平面反射镜和双椭圆反射镜BWG系统。模拟了波纹锥角馈入BWG的特性和BWG系统的输出光束模式，并与实测值进行了比较。

Design of Q-band beam-waveguide system for the satellite communication Earth antenna

Expanded Gaussian-Laguerre modes provides a more accurate and simple method to analyze the beam-waveguide (BWG) system. Using the propagated mode set and multiplication of the matrices for the BWGs factors, output field patterns with cross-polarized fields can be derived. A Q-band (33-50 GHz) BWG system which has two flat mirrors and two elliptic mirrors for a satellite Earth station antenna is designed. The characteristics of a corrugated conical horn for feeding to the BWG and the output beam patterns of the BWG system are simulated and compared with measured values.
