Asymmetric Circular Array Antenna Synthesis Based on Angular Positions

Mangolika Bhattacharya, Sudipta Das, Durbadal Mandal, and Anup Kumar Bhattacharjee
Abstract—In this paper, a broadside circular array antenna resting on x-y plane is assumed. Design aim here is to obtain the optimal combination of non-uniform angular positions of the elements and uniform radius for the array, so as to acquire the radiation with the lowest possible sidelobe peak (SLL) with least possible first null beamwidth (BWFN) increment. Optimum angular locations of elements are found using Real coded Genetic Algorithm (RGA).

Index Terms—Circular array, asymmetric circular array, sidelobe reduction, optimal angluar location, real coded genetic algorithm.
