Abstract

In this paper optimal side lobe reduction is achieved for time modulated linear antenna arrays with optimized uniform inter-element spacing and non-uniform excitations. An evolutionary approach, RGA, is proposed for the optimization. The side lobe level of time modulated linear array can be reduced significantly by optimal rearrangement of static excitation amplitudes and inter-element spacing of each element by RGA. The approach is illustrated through 12-, 16-, 20- element time modulated linear antenna arrays. Various results are presented to show the advantage of this approach considering maximum side lobe reduction.
