ABSTRACT In this paper, the optimal reduction of side lobe level with constraints of a suitable first null beam width of a non-uniform concentric elliptical array antenna of uniformly excited isotropic elements is described. Three meta-heuristic optimization algorithms, namely, ant lion optimization, crow search algorithm, and moth fly optimization algorithms are used for the optimal synthesis of the considered array structure in vertical plane and in horizontal plane. Simulation result shows that the optimized side lobe level value is reduced compared to a uniform concentric elliptical array antenna of same size and same number of elements for both the planes.

将非均匀间隔同心椭圆阵列天线的旁瓣电平最小化，以获得垂直和水平平面中第一零波束宽度的所需值

摘要 在本文中，描述了在均匀激励各向同性元件的非均匀同心椭圆阵列天线的合适第一零波束宽度约束下的旁瓣电平的最佳降低。三种元启发式优化算法，即蚁狮优化、乌鸦搜索算法和飞蛾优化算法用于垂直平面和水平平面考虑阵列结构的优化合成。仿真结果表明，与两个平面相同尺寸和相同元件数的均匀同心椭圆阵列天线相比，优化后的旁瓣电平值降低。
