本文介绍了一种微带三模谐振器，该谐振器是通过在已有的微带方环双模谐振器上增加一条附加路径来实现的。附加路径是通过连接到方环谐振器的两个相对角的弯曲半波长条实现的。利用该谐振腔设计了一个三阶伪椭圆带通滤波器。理论、仿真和实测结果吻合较好。
This paper introduces a microstrip triple-mode resonator that is realized by adding an additional path to an already reported microstrip square-loop dual-mode resonator. The additional path is realized by a meander half wavelength strip that is connected to two opposite corners of the square-loop resonator. A third order pseudo-elliptic bandpass filter utilizing this resonator is presented. Good agreement is achieved between the theoretical, simulated and measured results.
