Abstract
A semi-trapezoidal probe-fed dielectric resonator antenna (DRA) of very wide bandwidth is studied theoretically and experimentally. The design is an evolution of the double-slab DRA that exploits the advanced antenna geometry and the position of the feeding probe in order to facilitate the excitation of multiple modes with similar radiation characteristics. As a result, an impedance bandwidth of 62 per cent is achieved, while the patterns remain broadside and the polarization purity is within acceptable limits for the entire frequency domain.
