Synthesis of new antenna arrays with arbitrary geometries based on the superformula

<span lang="EN-US">The synthesis of antenna arrays with low sidelobe levels is needed to enhance the communication systems’ efficiency. In this paper, new arbitrary geometries that improve ability minimize level, are proposed. We employ well-known superformula equation in field by implementing general array factor equation. Three metaheuristic optimization algorithms used synthesize and their geometries; antlion (ALO) algorithm, grasshopper algorithm (GOA), a hybrid based on ALO GOA. All proposed high-performance computational methods, which proved efficiency for solving different real-world problems. 15 design examples presented compared prove validity most standard geometry: elliptical (EAA). It observed outperform EAA 4.5 dB 10.9 worst best scenarios, respectively, proves advantage superiority our approach.</span>
