Abstract :
Creation of nulls in specified directions is desirable in order to reduce the effect of interfering signals. But in large antenna arrays there possibility of getting a fault from some of the radiating elements can not be denied. In such a situation, the pattern of the array get distorted mostly with an increasing sidelobe level and removable of the null from its desired position. In this paper a method using particle swarm optimization(PSO) is developed to maintain the null position of the failed antenna array.
