In this research paper, the design of C-shaped Defected Ground Structure (DGS) antenna is proposed to realize dual-band characteristics for C-band and X-band applications. The proposed antenna consists of C-shaped slot incorporated in ground plane which resonates at two different frequencies (fr1 and fr2) of 7.41 GHz and 9.28GHz which lie in C-band and X-band respectively. A very good return loss (S11) of 30.79dB and -40.75dB are obtained at first and second resonant frequencies respectively for C-shaped DGS antenna.
