In this paper, circular, hexagonal and Octagonal array geometries for smart antenna applications are compared. Uniform circular (UCA), uniform hexagonal (UHA) and uniform Octagonal arrays (UOA) with 24 half-wave dipole elements are examined. An efficient global hybrid optimization method is proposed combining the Central Force Optimization (CFO) as a global optimizer and Hillclimbing (HC) algorithm as a local optimizer. After the final global iteration, a local optimization can be followed to further improve the solution obtained from the CFO. The CFO-HC algorithm is used to optimize the complex excitations, amplitudes and phases, of the adaptive arrays elements for beamforming, the CFO-HC algorithm was implemented using MATLAB-software and linked to the CST simulator to simulate the adaptive arrays.
