文章首先从基片集成波导谐振腔场结构出发,在半模谐振腔的基础上提出了四分之一模谐振腔结构。设计了一个两级四分之一模谐振器组成的基片集成波导滤波器,利用HFSS电磁仿真软件分析了滤波器的性能,结果显示滤波器通带阻带特性均能满足一般工程应用要求,验证了四分之一模结构的可行性。 First of all, starting from the field structure of waveguide integrated resonator, a quarter-mode resonant cavity structure is proposed based on the half-mode resonant cavity. The design of a two-stage quarter-mode resonator substrate integrated waveguide filter, the use of HFSS electromagnetic simulation software to analyze the performance of the filter, the results show that the filter passband stopband characteristics can meet the general engineering requirements, Verify the feasibility of a quarter of the mold structure.
