Optimization of linear antenna array using geneticalgorithm for reduction in Side lobs levels and improvingdirectivity based on modulating parameter M

Side lobe and directivity of antenna array is main problem in radar and communication field. This paper describes linear antenna array radiation pattern in adaptive beam forming using genetic algorithm. Unlike Simple GA (SGA), Genetic Algorithm is an iterative stochastic optimizer that works on the population values based on the fitness value. This improves the performance of the maximum reduction in side lobe level with less no. of function calls and achieves the maximum directivity in the direction by modulating parameter M. This technique proved its effectiveness in improving the performance of the antenna array.
