Optimization of Coupled Periodic Antenna Using Genetic Algorithm with Floquet Modal Analysis and MoM-GEC

In this paper Genetic Algorithm has been integrated with Fouquet modal analysis to optimize radiation pattern of coupled periodic antenna. Floquet is used MoM-GEC (Moment-Generalized Equivalent Circuit) method study a finite array uniform amplitude and linear phase distribution. This very advantageous for studying large antenna since it considerably reduces the computation time number operations. way, algorithm introduced combined distribution The goal optimization provide better characteristic maximum side lobe level reduction.
