Applying the NGF-enhanced Domain Green´s Function Method to the analysis of antenna arrays and ground planes of finite sizes

In this work, antenna arrays will be analysed in the presence of ground planes that are both of finite extent. A hybrid approach between a partitioned MoM scheme called the Numerical Green´s Function (NGF) and the Domain Green´s Function Method (DGFM) is presented, viz., the NGF-enhanced DGFM. The method allows for computationally efficient simulations, in that various array configurations can be investigated without solving again the part of the problem associated with the ground plane.
