This work introduces an effective technique for the linear antenna array pattern synthesis using the genetic algorithm optimization approach. Numerical designs are discussed to demonstrate the diverse capabilities of this technique for varying numbers of elements with constant distance between elements (d=λ/2). The key design of this work is to generate the excitation amplitudes only of the linear antenna array to place the nulls in undesired directions (nulling the undesired signals) and steering the main pattern in the desired direction (direction of desired signal) by altering the phase excitation currents. The fitness function is derived by maximizing the difference between desired pattern and actual pattern. Finally, this technique proved its effectiveness in improving the performance of the antenna array.
