【摘要】 利用等效电路理论分析了一种慢波开环谐振器,并结合多层结构设计了一种新型的椭圆函数滤波器。这种滤波器的传输特性由分布在电介质上、下表面的慢波开环谐振器相互耦合构成,且上、下表面谐振腔之间的耦合通过引入接地板上的耦合孔得到。为了验证这一方法,设计了一个四腔的带通滤波器,理论分析和全波仿真结果一致。更多还原

【Abstract】 In this paper,a slow-wave open-loop resonator was analyzed by equivalent circuit theory.With multilayer structure,a novel kind of elliptic filter is developed.The transmission property of filter is obtained by the coupling of resonators which placed on two stacked layers,where the coupling between the resonators on the upper layer and those on the lower ones is obtained by introducing two slots in a common ground plane.To validate this approach,a four pole bandpass filter was designed.There is agreement between theoretical analysis and the simulation data.更多还原
