In this paper, a new Defected Ground Structure (DGS) consisting of I-shape slot in ground has been presented to enhance the bandwidth of the Microstrip Patch Antenna (MPA). The parameters such as Bandwidth, Return loss and VSWR are much improved in proposed antenna than simple MPA without defected ground structure. Finite Element Machine (FEM) based High Frequency Structure Simulator (HFSS) software Version-13.0 is used to obtain the performance parameters of the proposed antenna. A comparison is also shown for the proposed antenna with the antenna structure without defect.
