枝节加载的双模微带滤波器设计
Design of microstrip dual-mode filter based on stub-load
摘要
Abstract
To realize compact and high performance filters, the induced mechanism of the resonant mode and transmission zeros of centrally stub-loaded E-shape dual-mode resonators was analyzed. It was found that the location of the transmission zeros could be set by controlling the relationship of odd-even mode resonant frequencies. On account of the above, several different band-pass filters were designed to verify the conclusion. Novel compact structure, good frequency selectivity and out-of-band rejection diplexers and double bandpass filters were presented by introducing transmission zeros to proper locations. The measured positions of the transmission zeros out of band agree well with the simulation result. The method can be used in microwave circuits design.关键词
