Microstrip antenna is a vital component of modern wireless communication systems. Therefore it requires optimized design for improving the overall performance of the system. The advancement of wireless devices including mobile equipments is ever growing area towards implementation. In this field importance of the antenna technologies grow accordingly. As handsets improve in compactness with multi functions in recent age, the antennas for these equipments have come under the spotlight. In this paper, the designing and analysis of T-slot microstrip patch antenna are presented. The shape will provide the broad bandwidth which is required for the operation of next generation wireless systems. Evolutionary Algorithm based optimization has been utilized in HFSS-ANSOFT to optimize the microstrip line feed antenna dimensions in order to obtain reliable return loss and high directivity. The operating frequency of antenna is 7GHz, the dielectric constant and thickness of the antenna is 4.4 and 1.6mm respectively. The simulation results of antenna are done by the help of HFSS and MATLAB programming. The microstrip patch antenna is designed with different centre frequencies such as 5.5GHz, 11.25GHz and 12.25GHz. The patch antenna is analyzed for different metrics for performance. A comparative analysis between non-optimized patch design and optimized patch design has also been presented.
