摘要: 该文提出了波导中介质层式的PBG结构，并对其阻带特性进行了数值分析，其中包括PBG 结构的设计，周期长度、周期个数、单元尺寸等几个方面对阻带特性的影响等，并给出了结论。利用介质层PBG结构来制作波导滤波器具有设计简单、易于实现的显著优点。Abstract: In this paper, a new dielectric layer PBG structures in waveguide is introduced, and numerical analysis to its stop-band characteristic is finished. The design of PBG structures and the effect of the size of period, the number of periods, the size of unit etc. are presented. And the conclusion is presented too. It is easy to design and manufacture waveguide filter using dielectric layer PBG structures.
