In this work, a 5 x 5 metamaterial array split ring resonator is introduced onto a C -shaped rectangular patch antenna with a defective ground plane. The patch antenna was designed to operate at the downlink radio frequency band of GSM 900 with a pair of bevel shaped structure and a horizontal slot on top which was closely put at the center of the patch. The objective of this paper is to investigate the effect of metamaterial and the orientation of DSRRs with strip lines behind on the

The results indicates that the amelioration in impedance bandwidth was 23.33% (77 MHz), gain of 44.4% (0.993 dB) and increase in return loss of 19% (6.71 dB ) when compared to the conventional patch antenna.
