In recent years, evolutionary optimization (EO) techniques have attracted considerable attention in the design of electromagnetic systems of increasing complexity. This paper describes a method of synthesis of uniform circular array antenna using three recent search heuristics: Modified Particle Swarm Optimization (MPSO), Differential Evolution (DE) and Artificial Bee Colony (ABC) optimization algorithms...
In many applications it is desirable to have the maximum radiation of an array directed normal to the axis of the array. In this paper, the broadside radiation patterns of three-ring Concentric Circular Antenna Arrays (CCAA) with central element feeding are reported. For each optimal synthesis, optimal current excitation weights and optimal radii of the rings are determined having the objective of...
