摘要

This paper presents a design of dual-band bandpass filter using novel ring resonator and H-defected ground. The bandpass filter is designed optimized and realized using mixed coupled microstrip double ring resonators and two electrically coupled H-cells DGS resonators, which are etched in background of the structure. Using this new ring structure leads to generate a selective bandpass filter with two isolated passbands. The measurement results show that the optimized filter has two passbands, the first band from 1.6 GHz to 2 GHz and the other from 3.6 GHz to 5.5 GHz. The proposed structure occupies an area of (0.45 lambda g x 0.35 lambda g) with lambda g = 0.044 m. The simulated and experimented results show good agreement and validate the proposed approach.
