Multibeam Generation using Optimization Techniques

Generation of multi beams with equal height is complex and involved. The literature to trial with this problem is very limited. However, an effort is made in this present work to generate such complicated patterns using state-of-the-art optimization algorithms. Few arrays are considered to generate multi beam by applying Firefly and PSO algorithms. The values of parameters of elements in array antennas are varying in nature. The results realized by applying Firefly and PSO algorithms are correlated and normalized patterns are conferred in U domain. Communication between multiple users is made easy by using antennas with multi beam. The trial of this work is very significant as the generated pattern doesn't exhibit any side lobe and hence EMI problem is eliminated.
