摘要：
This article presents a novel miniaturized bandpass filter using a square ring. Each side of the ring is loaded almost at one of the ends with a stub. Die stub increases the current path length: bring down the resonance frequency of the ring. The other end of each stub is terminated with a square patch whose size is kept such so is to give a dual-mode characteristic. The proposed filter offers a size reduction of 67% over an unloaded square ring resonator. (C) 2009 Wiley periodicals, Inc.
