Design of a Square Microstrip Antenna Using Genetic Algorithms
Main Article Content
Abstract
This research paper is to present how to design a square microstrip antenna using Genetic Algorithms at 2.45 GHz by MATLAB and CST programming. A square antenna patch is designed with a symmetrical structure, corresponding to the short-circuit technique of beamforming (rather than a rectangular patch using a conventional design). Generally, a conventional design will result in a rectangular rather than a square shape. Simulation results show that the methods presented in this paper can be used to really design the antenna with a return loss close to below -10 dB at the operating frequency.
