In this article, the authors report that multiple notches are precisely positioned within the bandpass filter's bandwidth by using a composite resonator and several semicircular defected ground structures (DGSs). The authors say that the ultrawideband (UWB) bandpass filter, implemented with a combination of multiple-mode resonator (MMR) and simplified composite right/left-handed (SCRLH) structures, achieved the desired passband with low loss while also adding two notches with high rejection.
