Abstract :
In this paper, the field distribution in the upper half space is divided into two regions: the fields in the upper hemisphere with r <;ae and the fields in the exterior region r > ae, where ae is a scale dependent on the geometry of the patch and the permittivity of the substrate. By employing dyadic Green´s functions expanded in these two regions, an exact solution is obtained to both near and far fields of circular patch antennas.
