摘要

采用一种新颖的结构，利用简单的环形谐振腔加载开桩，设计了具有低损耗和可控特性的双带带通滤波器。两个通带的分数带宽和传输零点是通过调整负载开断段的长度和两个馈线的距离来控制的。基于基板集成悬吊线(SISL)平台，设计实现了自封装低损耗滤波器，两个通带的损耗仅为0.45/0.83dB。实测结果与模拟结果吻合较好。

A controllable and low loss dual-band bandpass filter by using a simple ring resonator

A novel structure, which is built by using a simple ring resonator loading open stubs, is adopted to design a dual-band bandpass filter with low loss and controllable characteristics. The fractional bandwidths of two passbands and transmission zeros are controlled by adjusting the length of the loaded open stub and the distance of two feeders. Based on Substrate Integrated Suspended Line (SISL) platform, the filter is designed and implemented with self-packaging and low losses, which are only 0.45/0.83dB of two passbands. The measured results are well agreed with the simulated results.
