## 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
## Abstract We propose a compact dual band bandpass filter (BPF) using meandering stepped impedance resonators (SIRs). By appropriately selecting the impedance ratio (K) of the SIR, the harmonic frequencies can be tuned for generating the dualβpassband response. Using this structure, the bandwidth
## Abstract A new Iβshaped defected ground structure (DGS) is used to relocate the microstrip resonator's second harmonic at the proximity of the fundamental passband to realize dualβband bandpass filter. This DGS is validated by a compact dualβband bandpass filter at 1.44 and 2.35 GHz with simulat
