Abstract

We first develop an expression for the impedance matrix of two dipole antennas situated close and parallel to the edge of a semi-infinite perfectly conducting plane. We use the angular spectrum representation of the Green´s function of an infinitesimal dipole close to the ground plane and the induced electromotive force (EMF) method in order to determine the complex entries of the matrix. We also study the input impedance of one dipole radiating in the presence of a parasitic element and a semi-infinite ground plane by applying the developed approach and considering a two-port network model of the array antenna. Finally, the radiation patterns for two excited dipoles in presence of the ground plane configuration are calculated.
