The method of images on lossless dielectric ground planes

Abstract

This article is dedicated to the study of the images method, using half-wave dipoles on the dielectric ground plane, which is different from the widely known images method, which uses antennas on a ground plane (PEC). A review of the propagation models commonly used have been discussed. This paper presents a study of the images method at an air- dielectric ground plane interface. The experimental verification has been carried out by measuring the electric field as a function of distance, using half-wave dipole antennas for a frequency of 2.6 GHz, on a ceramic ground plane, for horizontal and vertical polarization. Ceramic floor at frequencies of f = 2.6 GHz can be considered a lossless dielectric media due to its negligible losses. The results of the images method have been modeled and discussed with a current image that has amplitude and phase for the dielectric ground plane.
