A novel lowpass filter (LPF) with a wide stopband by using defected ground structures (DGSs) and a transformed radial stub (TRS) in combination is proposed. The characteristics of DGS cells are investigated and the DGS embedded TRS LPFs are designed and verified by experiment. The designed DGS e...
