US Patent 7292204 Dielectric resonator antenna with a caved well

A dielectric resonator antenna is a dielectric resonator mounted on a feed-in/feed-out component. The dielectric resonator is a rectangular parallelepiped made of a dielectric, and has a caved well passing through from the top surface to the bottom surface thereof. The feed-in/feed-out component includes a dielectric substrate, a ground metal layer and a strip metal layer coated on the top surface and the bottom surface, respectively, of the dielectric substrate. An etched part is provided on the ground metal layer. Wherein, the dielectric resonator with the caved well is mounted on the ground metal layer of the feed-in/feed-out component.
