Abstract:
1. A dielectric resonator antenna comprising a dielectric resonator having a substantially planar longitudinal surface and a grounded substrate having first and second opposed surfaces with a dielectric substrate adjacent to the second surface, wherein: i) the grounded substrate includes a slot extending longitudinally in a first direction and having a predetermined width; ii) the dielectric resonator is arranged such that its longitudinal surface is disposed close to the first surface of the grounded substrate with a gap between the surfaces, and with an end region of the longitudinal surface overlying the width of the slot; iii) a majority of the longitudinal surface of the dielectric resonator is provided with a conductive layer, the end region of the longitudinal surface being free of the conductive layer; and iv) a strip feed line is provided on the dielectric substrate on the second surface of the grounded substrate, the strip feed line being substantially coextensive with the longitudinal surface of the dielectric resonator and extending beyond the width of the slot in the grounded substrate.
