A Distinct Approach Exploiting Collapse Distribution Colligated with Genetic Algorithm for the Synthesis of Thinned Planar Antenna Arrays

In this paper, authors propose a distinguishable technique, which synthesizes Thinned Planar Antenna (TPA) Arrays with maximally reduced peak side lobe level (PSLL). Authors employed Collapse Distribution Technique amalgamated with Genetic Algorithm (CDT-GA) in order to reduce optimization complexity and to obtain efficient control of PSLL. $8\times 8$- and $10\times 20$-elements TPA arrays are numerically analyzed to verify the effectiveness and examine the distinguishable features of the proposed strategy. The numerical results obtained through CDT-GA evidence that it outmatches the similar designs available in the literature. In order to further ascertain and validate the performance of CDT-GA in practical scenarios, authors realized an $8\times 8$-element TPA array and carried out experimental evaluation. The obtained empirical results are found nearly in agreement with corresponding numerically computed and electromagnetically simulated ones.
