Compact Step-Impedance Ring Resonator for Quad-Band Band-Pass Filter
By
Progress In Electromagnetics Research Letters, Vol. 41, 105-112, 2013
Abstract
A compact quad-band microstrip band-pass filter (BPF) based on novel step-impedance ring resonator (SIRR) is investigated in this paper. The proposed BPF is composed of one ring resonator and input/output coupled structure. The novel resonator is studied and employed to generate four desired independent passbands. A compact quad-band BPF centered at 1.57, 2.45, 3.5 and 5.2 GHz is designed and fabricated. The predicted results are compared with measured data, and good agreement is reported.
