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 ...
