| Abstract: | A novel butterfly shape defected ground structure for microstrip line was proposed. Its band gap characteristics and slow wave characteristics were discussed. Including the transmission loss, equivalent circuit modeling for the proposed microstrip line was built and its parameters were extracted. The effects of DGS dimensions on stop band characteristics were presented. Furthermore, a compact DGS low pass filter was designed and measured. The validity of the DGS filter is verified by the agreement between simulated and measured results. |

| Keywords: | defected ground structure microstrip line stop band slow wave structure low pass filter |
