Abstract
The invention relates to a dielectric resonator antenna (9) 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 (9), which are offered by the planes of symmetry (10) in a DRA, there is proposed to provide an electrically conducting coating on at least one curved surface (11) into which the tangential component of an electric field of an eigenmode assigned to the dielectric resonator antenna (9) disappears. As a result, the volume of the DRA (9) can be reduced considerably, although furthermore the same mode is found at the same frequency. Since there are a plurality of such curved surfaces (11), a particularly advantageous surface (11) can be selected depending, for example, on the desired degree of miniaturization, required bandwidth of the evolving antenna and manufacturing conditions.
