【摘要】 提出一种新型的具有双阻带特性的反向螺旋形缺陷接地结构(DGS),对该结构的参数变化进行了分析与仿真,发现根据其变化规律可以有效地调节双阻带的位置。利用该结构制作的带阻滤波器,阻带窄、衰减陡峭。通过软件优化设计了一个阻带分别位于3.5GHz和6GHz的双阻带滤波器,从HFSS软件仿真的结果证明了这种新型DGS结构的有效性和可行性。更多还原

【Abstract】 A novel anti-spiral-shaped defected ground structure(DGS) with dual-stop band is proposed,the variety of structure parameter is analyzed and simulated,and the position of dual-stop band can be availed by the variety rule.Band stop filter made with this structure has narrow gap and steep attenuation.This paper designs a dual-stop band filter which gaps located 3.5GHz and 6GHz.The validity and feasibility of the novel DGS has proved by HFSS simulating.更多还原
