HL-2A装置低杂波天线TE10模过渡段设计

摘要

Based on PAM, the 3-dB power splitter, the mode converter, the coupler and the water load are developed into an integrated module. The coupled wave thoery is used to design the TE10 taper. The parameters is optimized with HFSS code. Finally the results are obtained, the length is 370mm; the VSWR is 1.0012 and the reflection loss is -65.81 dBo%介绍了将 3-dB 功率分配器、模式转化器、耦合器、水负载等常规波导器件发展为单元模块集成部件的基于 PAM 概念的新一代低杂波天线,利用耦合模理论分析设计了TE10 模过渡段的结构参数,使用高频电磁场仿真软件 HFSS 进行结构仿真和参数优化,得到了过渡段长度为 370mm,驻波比为 1.0012、反射损耗为-65.81dB 的结果.
