Abstract—Array synthesis is usually done by controlling amplitude and phase levels or element spacing functions of the array to get the desired characteristics of the radiation pattern. This paper addresses the problem of designing thinned linear arrays with practical radiating elements dipoles to achieve lowest side lobe level. Traditional methods are not well suited for thinning large arrays; hence Genetic algorithm(GA) is used to find the optimum thinned configuration to achieve the specified sidelobe level .The computed patterns are compared with the uniform array patterns for different number of elements.
