A novel two-layer stacked wideband dielectric resonator antenna (DRA) of rectangular shape is proposed. The DRA is composed of a dielectric resonator (DR) and a thin dielectric segment, which reside above a ground plane, and is excited by a small metallic patch connected to a coaxial probe. Unlike its previous designs that have a DRA of a lower permittivity above one or more thin segments of higher permittivity, the top DR in this antenna has a higher permittivity than the lower segment. Theoretical and experimental results show that the proposed DRA can achieve a very wide bandwidth.
