摘　　要：介绍了采用铁氧体薄膜的微带环行器的工作原理、结构以及环行器阻抗匹配网络。对环行器进行了分析以及设计。在Ansoft公司的仿真软件HFSS中建立了环行器的模型进行了仿真,并对各个部分尺寸进行了优化。设计的薄膜环行器铁氧体薄膜厚度为10μm,在X波段(9.67～9.68GHz)可以达到插损低于1dB,隔离度大于20dB的设计要求。The basic operation principle, structural characteristics and microstrip impedance-matching network of ferrite film circulator are introduced. The structure＇s size of film circulator is analyzed briefly and designed. The microstrip impedance-matching network is set up and simulated by HFSS of Ansoft. The parameters of circulator are obtained by adjusting design size to make the film circulator fit in with the demands of the cirlator. When the thickness of the ferrite film is 10μm, the insert loss of the film circulator can be less than 1 dB and the isolation of the film circulator can be great than 20 dB in X-band（9. 67～9. 68 GHz）.
