Description
Summary:Antenna array synthesis with the least possible number of elements for obtaining the desired radiation pattern is important in some applications, for example, satellite communication, where the weight of antennas is limited. The objective of this paper is thinning of Concentric Circular Antenna Arrays (CCAA) to achieve a reduction in weight and cost. In this paper, swarm intelligence technique, Binary Salp Swarm Algorithm (BSSA) is introduced for synthesis of thinned CCAA. Thinning of antenna array requires the expulsion of a few antennas in the stretch of antennas so as to attain similar radiation characteristics as that of a densely occupied array. The BSSA approach is proposed to synthesize a CCAA to decrease the maximum side lobe level (MSLL), simultaneously by maintaining the percentage of thinning equivalent or higher than 50%. A CCAA with 440 antennas is optimized by the BSSA approach and is compared with other state-of-the-art approaches to demonstrate its efficacy.
