Abstract

In this article, a compact narrow-bandpass filter with high selectivity and improved rejection level is presented. For miniaturization, a pair of double negative (DNG) cells consisting of quasi-planar chiral resonators are cascaded and electrically loaded to a microstrip transmission line; short ended stubs are introduced to expand upper rejection band. The structure is analyzed using equivalent circuit models and simulated based on EM simulation software. For validation, the proposed filter is fabricated and measured. The measured results are in good agreement with the simulated ones. By comparing to other filters in the references, it is shown that the proposed filter has the advantage of skirt selectivity and compact size, so it can be integrated more conveniently in modern wireless communication systems and microwave planar circuits.
利用具有手性的紧凑螺旋谐振器设计窄带宽带通滤波器
本文提出了一种紧凑的窄带通滤波器,具有高选择性和高抑制水平。为了小型化,一对双负(DNG)电池组成的准平面手性谐振器级联和电负载到微带传输线;引入短端存根以扩大上部抑制带。利用等效电路模型对其结构进行了分析,并利用电磁仿真软件对其进行了仿真。为了验证,制作并测量了所提出的滤波器。实测结果与模拟结果吻合较好。通过与文献中其他滤波器的比较,表明该滤波器具有裙边选择性好、体积小等优点,可以更方便地集成到现代无线通信系统和微波平面电路中。
