This paper presents a clonal selection algorithm based on human immune system for null steering of linear antenna arrays by controlling only the element amplitudes. Design requirements such as the null depth level, maximum sidelobe level, and dynamic range ratio are considered in the optimization process. Several examples of Chebyshev pattern with the imposed single, multiple and broad nulls are given to show the accuracy and flexibility of the proposed clonal selection algorithm.
