Open the CIPO recordAbstract From the Canadian patent
An ultra-wideband antenna for operating in a frequency is disclosed wherein a monopole antenna, extends from a ground plane. The monopole has an effective length L of one , quarter wavelength, at the lowest frequency f1. A dielectric resonator antenna (DRA) surrounds the monopole antenna, for resonating at substantially between or at two and three times the lowest frequency f1. the DRA, is of a height of less than 3/4L and is disposed in such a manner as being above the ground plane, and either contacting or spaced therefrom by a gap G wherein 0 <= G , <= 0.2H. The ultra-wideband antenna is of a much greater bandwidth than the sum of bandwidth of the monople or the DRA, alone.
