| Abstract: | A novel triangular shape defected ground structure for microstrip line unit is proposed. Its bandgap characteristics are discussed. The equivalent circuit modeling for the proposed DGS microstrip line unit is built and its parameters are extracted. Furthermore , a compact DGS bandpass filter is designed. 3-D HFSS simulation results show the newly proposed DGS bandpass filter has wider stopband characteristics than those of conventional bandpass filters in the frequencies range of 3GHz to 7GHz. The validity and feasibility of the filter is verified by the simulated results. |
