摘要
本文对Rotman透镜进行了设计分析与研究。将冗余端口加入输入端口之间,以保证输入端口的宽度,使得Rotman透镜达到更好相位和传输效率,并采用微带形式设计Rotman透镜,具有易加工,低成本的特点。并用HFSS软件仿真验证了这一变化的实际效果,使得该透镜实现了透镜在1.71~2.3GHz,实现VSWR<1.5,插入损耗<2.6,隔离度<-17.5d B,波束指向为±12°,±34°,具有宽频带的特点。
In this paper the analysis and design method of microstrip Rotman lens is studied. Dummy ports are added between two input ports so that Rotman lens achieves better phase and transfer efficiency by the guarantee of the width of the input port, and this Rotman lens designed by microstrip has the characteristic of easy fabrication and low cast. The effect of change is confirmed by the simulation of HFSS,this Rotman lens realized that VSWR<1.5,Insertion loss<2.6, Isolation <-17.5d B, Beam pointing is ±12°,±34° and Broadband.
