Antenna surface modeling by rectangular plates

A modeling technique making use of the series of works [1, 2, 3] presented earlier, is given here. Large surfaces or plates are modeled by interconnected rectangular plates of moderate sizes. Entire domain basis functions are used to approximate the orthogonal surface current components on the plates. Plate junctions at edges and corners are treated here by an extension of a previous approach[5] in order to enforce the boundary conditions and reduce the size of the matrix equation.
