“…As reported in [1], a simple microstrip stub served as the impedance matching element and provided around 13% bandwidth improvement when get compared with the traditional design. Several monopole designs have been studied employing various ground planes of dissimilar shapes so that the impedance bandwidth can be enhanced [2][3][4]. A number of designs have been used to reduce size of MPA which includes the implementation of planar inverted F antenna (PIFA) or substrate with high dielectric constant.…”

“…Studies to get compact and broadband operations of microstrip antennas have increased greatly. To enhance the impedance bandwidth, the monopole with different shapes is used [1][2][3][4]. According to the open literatures, the shape of conventional square monopole was changed to triangular and disc-shaped so as to improve impedance bandwidth.…”

In this research paper, the design of C-shaped Defected Ground Structure (DGS) antenna is proposed to realize dualband 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 (f r1 and f r2 ) of 7.41 GHz and 9.28 GHz which lie in C-band and X-band respectively. A very good return loss (S 11 ) of -30.79 dB and -40.75 dB are obtained at first and second resonant frequencies respectively for C-shaped DGS antenna. The Bandwidth of C-shaped DGS antenna is increased by 825 MHz and 1182.8 MHz respectively at two different bands than the bandwidth of the Conventional Rectangular Microstrip Patch Antenna (CRMPA). Also VSWR is much improved with C-shaped DGS antenna. The comparison of simulated results of proposed and CRMPA has also been presented in this paper. The main contribution of this paper is the miniaturization of ground plane of 23% using C-shaped DGS which is very much encouraging.
