Abstract: Microstrip patch antenna is one of the important elements in modern wireless communication systems and hence its design optimization is an important aspect for improving the overall performance of the system. In this paper Genetic Algorithm optimization technique has been utilized in IE3D software for optimization of the rectangular microstrip patch antenna dimensions in order to achieve better return loss, SWR and radiation properties. The patch is designed to operate in ISM band with the centre frequency at 2.4GHz and various important performance metrics of the patch antenna are analyzed for performing comparative analysis between un-optimized patch design and optimized patch design. A GUI has been designed in MATLAB for obtaining the patch dimensions based on theoretical formulas.
