本文将传统的微带谐振器用于构建紧凑型多模谐振器(MMR)。弯曲谐振器是超宽带(UWB)带通滤波器的一种简单而方便的设计方法。在此基础上，利用两个谐振器实现了通带六个传输极点的超宽带微带滤波器。该滤波器的幅频响应范围为1.8~4.7 GHz，模拟回波损耗在通带优于−20d B，实测回波损耗优于−19d B。测试的中心频率插入损耗约为0.38分贝。文中还讨论了这种新型超宽带滤波器的带宽调整方法。©2016威利期刊，Inc.微波技术通讯58：2026-2029,2016
In this paper, traditional microstrip resonator is meandered to construct a compact multi‐mode resonator (MMR). The meander resonator is very simple but convenient for ultra‐wide band (UWB) passband filter. And then, a UWB microstrip filter with six transmission poles in the passband is achieved by using only two resonators. The filter has an amplitude frequency response with a passband from 1.8 GHz to 4.7 GHz, the simulated return loss in passband is better than −20dB, and the measured one is better than −19dB. The tested insertion loss at center frequency is about 0.38 dB. Methods of adjusting the bandwidth of this new kind of UWB filter is also discussed in this paper. © 2016 Wiley Periodicals, Inc.
