Abstract

This paper presents a novel dual-band bandpass filter by utilizing a new dual-mode resonator and a pair of single-mode split-ring resonators. The center frequencies and bandwidths of both passbands can be independently adjusted without affecting each other. Meanwhile, a capacitive source-load coupling is introduced to create transmission zeros near the passband edges, and the filter can obtain high skirt-selectivity. Such a dual-band bandpass filter operating at 3.5 GHz and 5.85 GHz with compact size is designed and fabricated.
