Clonal selection algorithm for design of reconfigurable antenna array with discrete phase shifters

In this paper, a method based on the clonal selection algorithm (CLONALG) is presented to design a reconfigurable dual-beam linear antenna array with excitation distributions differing only in phase. The CLONALG is a relatively novel population-based evolutionary algorithm inspired by the clonal selection principle of the human immune system (IS). From the practical implementation viewpoints, the proposed method takes discrete phase shifters into account during synthesis. Numerical examples showing a good agreement between the desired pattern and the synthesized pattern by using CLONALG are given.
