Design of linear antenna arrays using antlion and grasshopper optimization algorithms

摘要

The design of linear antenna arrays is one of the important electromagnetic optimization problems. In this paper, the problem of designing these arrays for specific radiation properties is dealt with. The Antlion optimization (ALO) and Grasshopper optimization algorithm (GOA) methods, which represent new evolutionary algorithms, are used in the optimization process. ALO and GOA are used to minimize the maximum side lobe level (SLL) by optimizing the excitation current amplitudes of array elements. The results obtained show the effectiveness of ALO and GOA compared to other optimization methods.
