Abstract

In this paper, the radiation characteristics of a non-uniformly spaced linear antenna array are synthesized to reduce the sidelobe level (SLL) and increase the directivity of the main lobe. A firefly algorithm (FFA) has been used to determine the optimum spacing between the antenna elements. The computations are carried out for a different number of elements ranging from N = 40 to 80. Finally, it has been evident that for a fixed number of iterations, the sidelobe level has reduced.
