Abstract

There is disclosed a dielectric antenna comprising a dielectric substrate having first and second opposed surfaces, the second surface being provided with a conductive groundplane and a dielectric pellet being mounted on or adjacent to the first surface. A feed mechanism is formed on or in the substrate for transferring energy to or from the dielectric pellet. The dielectric pellet has a top surface distal from the first surface of the substrate, a bottom surface proximal to the first surface of the substrate, a front surface facing towards a central part of the first surface of the substrate, a rear surface facing away from the central part of the first surface of the substrate and two side surfaces. The top surface and rear surface only of the dielectric pellet are provided with an electrically conductive coating or layer. The antenna is highly compact yet still offers good gain and bandwidth.
