This article presents an optimization immune algorithm (opt-IA) for null steering of linear antenna arrays by controlling only the element amplitudes. Nulling of the pattern is also achieved by controlling the phase-only and the complex weights (both the amplitude and phase) of the array elements. T

In this article, pattern nulling techniques for linear antenna arrays that make use of phase and position perturbations based on the genetic algorithm are in¨estigated, respecti¨ely. Both nulling techniques are found to be capable of steering the array nulls to the prescribed interference directions
