Spurious harmonics suppression of tapered SIR band-pass filter using electromagnetic bandgap (EBG) structure

This paper presents a novel design and development of tapered line stepped impedance resonator (SIR) band pass filters using electromagnetic bandgap (EBG) structures. EBGs are studied in order to suppress the spurious harmonics of the filter. The proposed EBG structure finds promising applications in suppressing the spurious harmonics in filters which has a tremendous application in hybrid microwave integrated circuits (HMICs) and monolithic microwave integrated circuits (MMICs).
