초록

This letter presents the design and measured performance of bandpass filters based on a stacked-SIR (stepped impedance resonators) configuration with DGS (Defected Ground Structure). An unit DGS configuration is designed and analyzed to show the phase characteristic of proposed slow-wave structure. The SIR filter with DGS has been yielded better stop band and sharper skirt behavior than conventional bandpass filter.
