Ka波段微带环行器设计与HFSS仿真
内容简介：设计了一种Ka波段微带结环行器，阐述了微带环行器的工作原理、设计方法与仿真过程。在理论分析的基础上，计算出圆盘结和“大Y结”尺寸。利用三维结构电磁场仿真软件Ansoft HFSS 进行建模、仿真分析，并对其进行优化处理。实验结果表明，该微带环行器在31～40GHz范围内，插入损耗小于0.3dB，电压驻波比小于1.2，隔离度大于20dB，相对带宽大于25%，仿真数据及实验结果满足设计要求。
Abstract：A Ka-band microstrip circulator is designed. The working principle,simulation process and design method of microstrip circulator are descriped in this article. Based on theoretical analysis the size of discoidal-junction and Y-junction are calculated. Modeling and simulation of microstrip circulator are carried out with Ansoft HFSS. The result indicates that, in frequency range of 31-40GHz,the devices features insertion loss≤0.3dB, VSWR≤1.2,isolation≥20dB,relative bandwidth≥25%,meeting the design requirements .
