Rectangular Microstrip Patch Antenna with U-Shaped DGS Structure for Wireless Applications

A compact micro strip patch antenna with wide operational bandwidth is presented. The proposed design consists of rectangular patch antenna in ring shaped with U-slots cut in ground. Antenna is fed by micro strip line. The performance of rectangular patch antenna has been discussed and analyzed by modification of the patch dimensions. The proposed antenna is having bandwidth of 1300 MHz, gain 2.65 dBi and return loss -28.82 dB. The proposed antenna has been analyzed using IE3D and simulated results are presented in terms of bandwidth, gain and return loss.
