ABSTRACT
This paper describes the synthesis of the radiation characteristics of linear antenna arrays of dipole elements using a nature inspired algorithm called flower pollination algorithm (FPA), which is applied as an optimization algorithm. In FPA, element's current excitation and the inter-element spacing are used as the optimizing variables to obtain better radiation characteristics of the antenna arrays. The advent is illuminated by 12-, 16-, and 20-elements linear arrays of dipole elements. The simulation results show the influence of this approach on the maximum side lobe level reduction with fixed first null beam width. The obtained results are validated in a practical simulation environment, called computer simulation technology-microwave studio software.
