Design of Non-Uniform Circular Arrays for Side lobe Reduction Using Real Coded Genetic Algorithm

M.Nirmala, Dr.K.Murali Krishna

The purpose of this paper is to design of non-uniform circular antenna arrays for maximal side lobe level reduction. The antenna array design problem consists of finding weights that provide a radiation pattern with maximal side lobe level reduction. Real Coded Genetic Algorithm (RCGA) are very appropriate tools to search for the best antenna models. The effectiveness of Real Coded Genetic Algorithm (RCGA) for the design of non-uniform circular arrays is shown by means of experimental results. Experimental results reveal that design of non-uniform circular antenna array provides a considerable side lobe level reduction with respect to the uniform case.
