摘要: 該文提出了波導中介質層式的PBG結構，并對其阻帶特性進行了數(shù)值分析，其中包括PBG 結構的設計，周期長度、周期個數(shù)、單元尺寸等幾個方面對阻帶特性的影響等，并給出了結論。利用介質層PBG結構來制作波導濾波器具有設計簡單、易于實現(xiàn)的顯著優(yōu)點。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.
