Abstract

This paper presents proficient scheme of design optimization using curve fitting inspired PSO algorithm for improvisation of coplanar ground plane in CPW fed Microstrip Patch Antenna. Finite element based EM solver is employed for analyzing the performance of patch radiator. Tapering in ground plane is introduced for enhancement of operational bandwidth of patch antenna. Curve fitting technique is implemented over the data set generated by varying tapered length and width of ground plane to predict mathematical equations relating different antenna parameters. Using these equations,a fitness function is created for PSO based design optimization. The discussed approach for design optimization of CPW fed patch antenna results in better impedance matching with bandwidth enhancement of approximately 200 % (6.40 GHz-9.41 GHz), when compared to manual design optimization (6.46 GHz-7.44 GHz and 8.22 GHz-9.83 GHz) using trial and error method.The application of optimization techniques in electromagnetics has hindrance due to lack of appropriate fitness functions. The aim of the study is to use curve fitting approach for the generalization of fitness function so as to optimize the structure using a robust optimization algorithm instead of relying on common approach of trial and error method.
