Nowadays, Researchers are interested in new heuristic algorithms for optimization problems in many modern communications applications. Within this scope Grasshopper Optimization Algorithm is a newly released optimization algorithm. The proposed method is a mathematically models which mimics the behavior of grasshopper swarms in nature for solving optimization problems. Elliptical antenna array design has recently become a very popular field of antenna array studies. In this work, Grasshopper Optimization Algorithm is used to synthesis of elliptical antenna arrays having different number of array elements. For the purpose of elliptical antenna array synthesis, Grasshopper Optimization Algorithm is employed for determine the optimum amplitudes of the array elements. In this paper, the problems are solved by using antenna array synthesis together with maximum sidelobe levels and half-power beam width constraints. The results obtained by Grasshopper Optimization Algorithm are compared with Symbiotic Organisms Search Algorithm.
