Abstract :
Solutions detailing the radiated fields of patch antennas often determine the electric field components. These components are then combined with appropriate coordinate transforms to realize the spherical coordinate representation suitable for plotting radiation patterns. This paper presents a slight variation on this process that eliminates such a tedious calculation and realizes the electric fields directly from the asymptotic evaluation of the z-directed vector potentials "A" and "F".
