摘要 介绍了一种新型的互补开环谐振器(Complementary Split Ring Resonators,CSRR),用此新型谐振器和1/4波长传输线变换器制作了波导带通滤波器。在此基础上为了使滤波器更小型化,设计了挡板结构,改进了滤波器的1/4波长传输线变换器。通过对两种结构的仿真比较得出,新型结构的滤波器在满足设计需求的同时,将波导长度减少了54.9%。所设计的新型结构可以在很大程度上缩小滤波器的体积。 This paper introduces a new Complementary Split Ring Resonators.We design a waveguide bandpass filter using the CSRR as resonance elements and a λ/4 transmission line as an inverter.In order to reduce the length of the filter,we design an iris structure and improve the inverter using it.Comparing the two design plans,the length of waveguide reduces 54.9% in the new design plan.we can reduce the volume of filter to a great extent using the new structure.
