摘要
介绍了一种结构新颖、插入损耗小,且具有优异线性相位的环状微带线滤波器。该滤波器采用数个环形谐振器平行耦合,而输入输出馈线与环形谐振器之间采用直接耦合。文中列举了中心频率为8.6GHz的三环、四环和五环三种不同的滤波器,并对其进行了仿真模拟和结果比较。
A new low insertion-loss, linear-phase microstrip bandpass filter is introduced. This filter uses several parallel-coupling ring resonators and direct-coupling structure between feed lines and rings. This paper presents three filters with three rings, four rings and five rings whose center frequency is 8.6 GHz and compares their simulated parameters.
