Design of elliptical microstrip patch antenna using Genetic Algorithms

In this paper, Genetic Algorithms (GA) has been applied to calculate the optimized parameters of Elliptical Microstrip antenna. The inputs to the problem are thickness of the substrate, eccentricity, dielectric constant and even mode frequency. The output obtained is the optimized semi-major axis length `a´ from which the other parameters i.e. semi-minor axis length and odd mode frequency are calculated. The results obtained by GA are compared with the targeted results. The results are in good agreement. GA results are also compared with IE3D simulation results. These results are also comparable and thus validate the GA based code.
