An Investigation on the Optimal Synthesis of Concentric Ring Array Antenna Using Multi-verse Optimization Algorithm
摘要
Synthesis related to antenna arrays is a very trendy topic in the area of electromagnetics, radar and microwave engineering as it has attracted huge attention due to their large applications. This investigation presents an efficient synthesis approach for a uniformly excited concentric-ring array antenna using a very popular and widely used meta-heuristic called multi-verse (MVO) optimization algorithm. The primary objective of this study is to evaluate the design parameters of a concentric-ring circular array antenna that generates minimum side-lobes and highest directivity simultaneously. Two different cases with 6 circular concentric rings are taken into consideration to test the performance of MVO. In case one, optimized circular-ring radii but fixed element-to-element separation is taken into consideration whereas, in case two optimized circular-ring radii and element-to-element separation both are considered as constraints. The common performance parameters generated post simulation are recorded and presented in tabular format for comparison with each other as well with the published paper. The optimal values of the results that are obtained in second case are superior. The simulation-based results establish effectiveness of the proposed design and the efficiency of the MVO algorithm in dealing with the problem at hand.
