Abstract
This paper considers the efficient numerical analysis of arbitrary finite antenna array structures using the Domain Green's Function Method (DGFM). The DGFM is implemented in the comprehensive 3D electromagnetic field solver, FEKO [1], and uses the Method-of-Moments (MoM) formulation. The technique is based on that initially presented in [2] and is a perturbation approach where mutual coupling between antenna array elements is accounted for during the formulation of the Green's function for each element. The DGFM takes into account the edge effects attributed to the finite size of the array, complex excitations with non-linear phase shift and is not limited to periodic array configurations.
