摘　　要：功分器作为射频微波电路中常用的无源器件,一直以来都得到广泛的应用。首先介绍缺陷地结构,并对缺陷地模型进行理论分析,然后基于缺陷地结构设计1种工作在18~40 GHz频率范围内的渐变线的宽带Wilkinson功分器,仿真结果表明:在18~40 GHz频率范围内,最大插损为-3.15 dB,隔离度≤-10 dB,输出端口相位变化情况基本一致,S11在整个频段内回波损耗均<-18 dB,S22和S33在整个频段内回波损耗均<-14 dB。该基于缺陷地的Wilkinson功分器显著地提升Wilkinson功分器的工作带宽。As a passive component commonly used in RF microwave circuits,power dividers have been widely used.This paper first introduces the structure of the defect,and analyzes the model of the money-deficient land.Then,based on the structure of the defect,a broadband Wilkinson power divider with a gradient line working in the frequency range of 18~40 GHz is designed.The simulation result shows that in the frequency range of 18~40 GHz,the maximum insertion loss is-3.15 dB,the isolation is no more than-10 dB,the phase change of the output port is basically the same,the return loss of S11 is less than-18 dB in the whole frequency band,and S22 and S33 are in the whole frequency band.Return loss is less than-14 dB.The defect-based Wilkinson splitter significantly increases the operating bandwidth of the Wilkinson splitter.
