Many technologies have been introduced to provide improvement in parameters of microstrip patch antenna also introduce multiband operation in a single antenna due to the increasing need for compact and low power applications, in this paper defected ground structure (DGS) method is used to employ the multiband operation and enhance the parameter of the antenna, simple grid structure of DGS is embedded on the ground plane of conventional design. It is observed that the undesired performance of microstrip patch antenna in terms of parameter enhancement and multiband operation is obtained. The proposed structure has improved the parameter performance and also provided a size reduction of 67.9 % w.r.t. conventional design. The proposed antennas are found to match with simulation and measured reading using vector network analyzer. Antenna find application in various ISM and WIFI applications.
