本文提出了一种改进带外特性的折叠发夹谐振器微带带通滤波器。5极点发夹滤波器的中心频率为2 GHz，分数带宽（FBW）为0.2。滤波器的性能已得到改善，使用缺陷接地结构（DGS）和缺陷微带结构（DMS）在馈线中的组合，以消除从3.1到4 GHz的寄生通带。DGS和DMS的组合提供了相对宽的阻带，并且同时具有陡峭的上升和下降边缘裙，以便最小化实际通带中的失真。该结构已被设计使用RT/Duroid 6006基板的高度为1.27毫米和介电常数为6.15。提出的结构已被模拟的矩量法（MoM）基于IE 3D电磁仿真器。最后，该滤波器具有良好的带通响应，适用于现代微波和毫米波通信。
This paper presents an microstrip bandpass filter using folded hairpin resonators with improved out of band performance. The 5 pole hairpin filter has a centre frequency of 2 GHz with a Fractional Bandwidth (FBW) of 0.2. The filter performance has been improved using a combination of Defected Ground Structure (DGS) and Defected Microstrip Structure (DMS) in the feed line to remove the spurious passband extending from 3.1 to 4 GHz. The combination of DGS and DMS provides a relatively wide stopband and at the same time has a steep rising and falling edge skirts so as to minimize the distortion in the actual passband. The structure has been designed using RT/Duroid 6006 substrate with a height 1.27 mm and dielectric constant 6.15. The proposed structure has been simulated by Method of Moment (MoM) based IE3D electromagnetic simulator. Finally, the filter exhibits a good bandpass response suitable for use in modern microwave and millimeter wave communication.
