| 摘 要： | 设计了一种与传统发夹型滤波器不同的窄带带通滤波器.通过在振荡器上加载一段开路短截线,并在短截线的中心减去一个小方形作为微扰元件,得到需要的窄带频率响应.使用全波电磁仿真软件Ansoft HFSS进行仿真优化,设计出了中心频率为2.64GHz、带宽为20MHz的窄带滤波器.实测结果与仿真结果基本一致.

| Abstract: | In order to improve communication quality, the filter has become an indispensable part of modern communication systems. We design and achieve a microstrip bandpass filter based on hairpin line coupling structare. This structure is simple and the materials are easy to get. Good performance suggests it would have a wide range of applications. |
