Design and Optimization of Metal Cavity Bandpass Filter and Fragmented Patch Antenna By Combining Simulation Software and Genetic Algorithm

Abstract

Abstract An electromagnetic (EM) structure optimization method based on Genetic algorithm (GA) and EM simulation software is proposed. The aim is to accelerate optimization speed of electromagnetic structure and improve designed performance. An algorithm considered continuous and discrete problems is adopted to expand design domain of electromagnetic structures. In order to evaluate the performance of proposed method, a fourth-order cavity bandpass filter and a fragmented patch antenna are considered as two examples to verify the analysis.
