基于奇偶模分析法的四模谐振器结构的双通带带通滤波器设计
The Design of Dual-Band Bandpass Filter Using Novel Quadruple-Mode Resonator Based on Odd-and Even-Mode Method
摘要
Abstract
A new-type dual-band bandpass filter using a novel quadruple-mode resonator is proposed.This quadruple-mode resonator consists of four open-stubs and one short-stub.The odd-and even-mode method is adopted twice to analyze this resonator and good conclusions are given.Each resonant mode of the quadruple-mode resonator can be tuned independ-ently.Each two modes form a passband of the filter.Source-load coupling is introduced to improve out-band rejection.To testify the proposed theory and resonator structure,a high-selectivity dual-band bandpass filter is designed and fabricated.The measured results show that it has four transmission zeros and four transmission poles. This filter is centered at 2.08/6.07GHz with 3dB bandwidths 11.06%/7.74% respectively and it has a compact size,only 0.28λg×0.11λg.关键词
