Abstract :
In this paper, the method of imposing of nulls in the radiation pattern of an antenna array is hashed out using Real coded Genetic Algorithm (RGA). Circular array antennas lying on x-y plane is assumed. The array is assumed to have the maximum radiation along positive z-axis. Single and multiple nulls are imposed by optimizing the current amplitude excitations of each element through RGA. Various simulated results are presented and hence nulling performance is analyzed.
