波束波导传输系统与天线设计

内容简介：波束波导传输系统具有功率容量高、不需要旋转关节等优点,非常适合在大功率微波系统中应用。本文简单介绍了波束波导系统,设计了一款基于波束波导传输系统的天线,讨论了其馈源的设计及镜面的选取,并利用基于GRASP软件的QUAST模块进行了优化分析。为进一步验证GRASP计算的可靠性,将波束波导天线前两个反射面在HFSS中进行了仿真,并与GRASP所得结果进行了比较,比较结果显示两者吻合较好。

Abstract：Beam waveguide transmission system has advantages of high power capacity and working without rotary joints, therefore it is suitable for applying in high-power microwave system. Beam waveguide transmission system is introduced briefly; an antenna based on beam waveguide transmission system is designed ; design of feed source and selection of reflectors are discussed; and optimization analyzing by using of QUAST module based on software GRASP is conducted. In order to verify reliability of GRASP computation further, simulation of two reflectors in front of beam waveguide antenna is conducted; and comparison between the simulation results and GRASP result shows that they are well coincident with each other.
