| Abstract: | In this paper, a comparative performance of microstrip filters loaded with various dumbbellshaped defected ground structures (DB-DGS) has been studied in terms of their bandstop characteristics. During this course, a new dumbbell shaped DGS having transmetal slit in the connecting slot of the square head in the ground plane has been proposed. This proposed design provides an improved bandstop response. For comparative analysis, all the filter characteristics have been simulated and studied at a fixed cutoff frequency using HFSS and co-simulation has been carried out with ADS-EM. In addition, a microstrip bandstop filter with the proposed DGS has been fabricated and tested. Measurements are in close agreement with the simulated results. © 2013 IAMOT. |
