First we designed a band pass filter at the center frequency of 6.85 GHz using the increased Parallel coupled lines. After that for enhancing the bandwidth of the filter defected ground is proposed on the same structure for that we introduced rectangular aperture on ground plane. Size of the filter is 24.1 mm and The passband of the proposed filter is from 3.2GHz to 11.6GHz with center frequency 7.7GHz.
