Linear Antenna Array Synthesis to Reduce the Interference in the Side Lobe Using Continuous Genetic Algorithm

Sidelobes in the radiation pattern causes degradation of actual signal and hence antenna power efficiency. This paper discusses the problem of interference suppression by reducing the side lobe. Synthesis of linear antenna array using Continuous Genetic Algorithm is done to search for the optimum amplitude weights to minimize the maximum side lobe level. It has been demonstrated that side lobe level is reduced effectively by this technique. The simulated results shows an improved directivity, reduction in the first side lobe and fast convergence. This shows the effectiveness of this technique.
