摘　　要：文中利用一种渐变尺寸的 DGS(Defected Ground Structure)结构的带阻特性,以改善毫米波滤波器的阻带性能.仿真及实验结果证明了优化的渐变尺寸周期 DGS 结构能有效地改善滤波器带外抑制特性,同时对通带内插入损耗影响较小.This paper uses the structure character of the step sized DGS to improve the effects of stop band in millimeter filters.Simulations and results of experiments show that the optimized structure of step sized DGS can improve the re- straining character out of the pass band of filters effectively and has few effects on the loss of insertion in pass band.
