在本文中，我们首先提出了一种采用单环谐振器的新型小型化双模双模带阻滤波器，它具有阻带宽、通带内插入损耗低的特点，并在此基础上提出了一种新型的多带通滤波器。所提出的滤波器的思想是使用多拒绝频带谐振器来设计传输频带，该多阻抗频带谐振器是使用直接耦合到输入/输出端口的多臂开环谐振器来实现的。每对谐振器臂在传输响应中创建拒绝带。通过适当地调整多拒绝频带，创建了适当的多传输频带。通过设计三种不同的具有多带通响应的滤波器，验证了该方法的有效性。设计和制作的滤光片体积小，测量结果与模拟结果吻合较好。©2010 Wiley期刊，Inc.微波OPT Technol Lett 52：2668-2672,2010；在wileyonlinelibrary.com上在线查看本文。DOI 10.1002/MOP.25576
In this article, we proposed at first step a new compact dual‐mode bandstop filter with broad stopband and low insertion loss in the passband using one ring resonator.Based of this microstrip ring resonator, a novel type of multibandpass filters is proposed. The idea of the proposed filters is to engineer the transmission band using multireject band resonators, which are implemented using multi‐armed open‐loop resonators that are directly coupled to the input/output ports. Each resonator pair of arms creates a reject band in the transmission response. By properly adjusting the multireject bands, appropriate multitransmission bands are created. The idea was verified by designing three different filters with multibandpass response. The designed and fabricated filters have compact size with good agreement between the measured and simulated responses. © 2010 Wiley Periodicals, Inc.
