摘要
Using slow-wave transmission line ring resonator and square-patch element, a novel compact dual-mode microstrip bandpass filter is developed in this article. A filter having a 3% bandwidth at 2 GHz is designed, fabricated, and measured. The design procedure is given, and the mode-splitting characteristic and impact of the patch element on the performance of the filter is investigated. The proposed filter has a smaller size compared with conventional dual-mode bandpass filters at the same central frequency. This compactness is about 35% for the fabricated sample.
