Multiple Flat Beams Generation Using Firefly and Teaching Learning Based Optimization Techniques

Multiple flat beams have an extensive range of applications in mobile and wireless communications. They facilitate many users to connect simultaneously. Multiple beam pattern can be produced utilizing both conventional and modern optimization techniques. Teaching learning based optimization and Firefly are applied for Multibeam purpose in this paper. Multibeam with a beamwidth of 0.2 (in U = sinθ) each are produced. In the present work, unsymmetric array antenna is utilized to generate the Multibeam pattern. The beams are well-formed, and they are observed to be optimized. The patterns are presented in U domain. The resultant distribution of antenna parameters is found, with the goal that they can be used directly in Array antenna design.
