一种双通带微带滤波器的设计

Abstract

Abstract:

In this paper,a dual-band passband filter with two H-resonators by fringe coupling is presented.The dual-band resonator consists of two parallel microstrip lines that are connected by a microstrip line and can show dual-frequency resonance.The two external quality factors change oppositely when the distance between the feed point and the center microstrip line becomes larger.As the distance between the two resonators becomes larger,the coupling coefficients of the dual-band resonator reduce simultaneously.Thus,a dual-band passband filter can be obtained by combining the two H-resonators.

Key words: H-resonator;external quality factor;coupled coefficient;dual-band
