摘　　要：文章基于对脊鳍线过渡结构设计并仿真了一种W波段的矩形波导—微带线的转换器。该转换器具有平面电路的几何结构优点,且空间体积小、质量轻,可广泛应用于毫米波平面传输线组成的电路中。通过仿真结果表明:在W波段(80~95 GHz)的频带范围内,该过渡结构的回波损耗小于20 dB,插入损耗小于0.4 dB。This paper designs and simulates a W-band rectangular waveguide—microstrip line converter based on the transition structure of the ridge—fin line.The converter has the advantages of planar circuit geometry structure,small space and light weight,and can be widely used in circuits composed of millimeter wave planar transmission lines.The simulation results show that:in the W band(80-95GHz)frequency band,the return loss of the transition structure is less than 20dB,and the insertion loss is less than 0.4dB.
