摘要: A novel multimode bandpass filter with good rejection band is proposed by using a radial stub. The stub cannot only perturb the traditional resonator for operation but also generate additional zero point at stopband control. With proper input/output coupling, two poles, that is, four can be achieved structure. experimental results of four-mode show low insertion loss, performance, and compact size. © 2009 Wiley Periodicals, Inc.
