The paper presents the design to increase the bandwidth of an inset feed micro-strip patch antenna using disconnected U-shaped defected ground structure (DGS). Since defects in the ground of the antenna change the current distribution, the bandwidth changes. A critical and comparative analysis of the three different antenna designs has been done. The first design is of a simple micro-strip patch antenna with inset feed. The second design consists of three defects in the ground of the antenna. The third consists of the DGS as well as a slot in the patch of the antenna. Simulation results show that the bandwidth increases with each design especially when DGS is applied. The proposed design is applicable for the frequency of IEEE S band—3.6 GHz.
