Abstract
The invention relates to a dielectric resonator antenna ( ) as well as a transmitter, a receiver and a mobile radiotelephone that includes a dielectric resonator antenna. To improve known possibilities of reducing the volume of the DRA ( ), which are offered by the planes of symmetry ( ) in a DRA, there is proposed to provide an electrically conducting coating on at least one curved surface ( ) into which the tangential component of an electric field of an eigenmode assigned to the dielectric resonator antenna ( ) disappears. As a result, the volume of the DRA ( ) can be reduced considerably, although furthermore the same mode is found at the same frequency. Since there are a plurality of such curved surfaces ( ), a particularly advantageous surface ( ) can be selected depending, for example, on the desired degree of miniaturization, required bandwidth of the evolving antenna and manufacturing conditions.
