提出了一种基于缺陷接地结构（DGS）、缺陷微带结构（DMS）和补偿微带电容的宽阻带（WSB）低通滤波器。通过仿真和测量验证了其优良的缺陷特性。除了锐截止外，该结构还具有简单的设计和制造，在0.3 dB的通带内具有非常低的插入损耗，并且在1.5 GHz至8.3 GHz范围内具有20 dB的总衰减的宽抑制带宽。紧凑型低通结构占据（0.40λg× 0.24λg）的面积，其中λg= 148 mm是截止频率为1.1 GHz时的波导长度。实测结果与仿真结果的对比验证了该方法的有效性。这种滤波器拓扑结构由于其几个优点（例如，小损耗、宽阻带和高紧凑性）而用于通信系统和微波技术的许多领域。
A novel wide stopband (WSB) low pass filter based on combination of defected ground structure (DGS), defected microstrip structure (DMS), and compensated microstrip capacitors is proposed. Their excellent defected characteristics are verified through simulation and measurements. Additionally to a sharp cutoff, the structure exhibits simple design and fabrication, very low insertion loss in the pass band of 0.3 dB and it achieves a wide rejection bandwidth with overall 20 dB attenuation from 1.5 GHz up to 8.3 GHz. The compact low pass structure occupies an area of (0.40λg× 0.24λg) whereλg= 148 mm is the waveguide length at the cut‐off frequency 1.1 GHz. Comparison between measured and simulated results confirms the validity of the proposed method. Such filter topologies are utilized in many areas of communications systems and microwave technology because of their several benefits such as small losses, wide reject band, and high compactness.
