摘要
提出了一种新型缺陷地结构的带阻滤波器。该单元在现有各种形状的基础上,采用新的缺陷地结构,实现了带阻特性。该单元结构简单,易于加工,性能优越,可进一步减小滤波器尺寸。文中对新型缺陷地结构单元的带阻特性进行了分析,并建立仿真模型,从理论和实验中得到最佳的性能。实现了有较宽阻带的周期性缺陷单元。能够有较宽的阻带。最终设计出实际带阻滤波器,并对产品进行了实际测量,得出与仿真相似的结果。
A new type of Defected Ground Structure（DGS） of band-stop filter is proposed in this paper.Based on the existing vari-ous types,the unit introduces a new band-stop DGS structure.This unit features simple structure,easy processing and excellent performance,and the dimension of a filter can be reduced.In this paper,band-stop property of the new DGS unit is analyzed and simulated,and the optimum simulation model with a periodic DGS unit with wide stop-band is presented.Finally,a practical band-pstop filter is designed,and the results of actual measurement on the filter are similar with those in simulation.
