Performance Analysis of Linear Antenna Array Using Genetic Algorithm

The genetic algorithm optimization method used in this paper for the synthesis of antenna array radiation pattern in adaptive beam forming. In this paper optimum value of weights of each antenna element is determined which produces radiation pattern with minimum side lobe level .Unlike Simple GA (SGA), real coded Genetic algorithm is used. Optimization is done using MATLAB. Adaptive feasible mutation is used which enables search in broader space along randomly generated directions to produce new generations. This improves the performance greatly to achieve the maximum reduction in side lobe level with minimum function calls.
