Abstract
An electromagnetic device includes: a ground structure; a dielectric resonator antenna (DRA) disposed on the ground structure; an electromagnetic (EM) beam shaper disposed proximate the DRA; and, a signal feed electromagnetically coupled to the DRA. The EM beam shaper includes: an electrically conductive horn; a body of dielectric material having a dielectric constant that varies from an internal portion of the body to an outer surface of the body; or, both the electrically conductive horn and the body of dielectric material.
Claims18
An electromagnetic device, comprising:
- an electrically conductive ground structure;
- at least one dielectric resonator antenna (DRA) disposed on the ground structure, the at least one DRA comprising a DRA having an overall height and an overall width where the overall height is greater than the overall width;
- at least one electromagnetic (EM) beam shaper disposed proximate a corresponding one of the DRA;
- and
- at least one signal feed disposed electromagnetically coupled to a corresponding one of the DRA;
- wherein the at least one EM beam shaper comprises a body of dielectric material having a dielectric constant that varies from an internal portion of the body to an outer surface of the body;
- wherein the at least one DRA comprises an array of the at least one DRA to form an array of DRAs;
- and
- wherein the array of DRAs are disposed at least partially around the outer surface of the body of dielectric material.
