Abstract
This paper presents a dual-band bandstop filter by using stub-loaded resonators. The frequencies of the two stopbands are 1.6G and 2.4G, respectively, with the frequency ratio of 1.5. Several zero points are introduced, which significantly improve the skirt selectivity. The frequency ratio can be flexibly designed, and the fractional bandwidths of each stopband can be controlled conveniently. Moreover, high attenuation is achieved in both stopbands.
