## Abstract This letter presents a novel approach for designing quadβband bandpass filter with independently controlled center frequencies.Assembled resonator constructed by a stepped impedance resonator (SIR) and a stubβloaded SIR is employed to obtain quadβband responses. The SIR is designed to o
