Abstract

This article presents a dumbbell shaped triangular split ring resonator (SRR) in the design of wideband bandstop filter. Initially, a conventional dumbbell shaped triangular defective ground structure (DGS) is used to realize the single bandstop filters at the frequency of 3.55 GHz. This triangular shaped DGS structure is modified to a new structure to realize a wideband bandstop filter characteristics with the frequency range of 3.3 to 4.5 GHz which can be suitable for wireless applications. The proposed filter has low insertion loss in the passband, sharp and wide rejection in the stopband and compact size compared to the conventional triangular DGS structure.
