Dielectric resonator antenna and method of making the same
First Claim
1. A dielectric resonator antenna (DRA) operable at a defined frequency, comprising:
- at least one volume of a dielectric material configured and structured to be responsive to a signal feed when electromagnetically coupled to the at least one volume of a dielectric material, the signal feed when present and electrically excited being productive of a main E-field component having a defined direction, Ē
, in the DRA as observed in a plan view of the DRA;
wherein the at least one volume of a dielectric material comprises a non-gaseous dielectric material having a defined dielectric constant, the non-gaseous dielectric material having an inner region comprising a dielectric medium having a dielectric constant that is less than the dielectric constant of the non-gaseous dielectric material, at the defined frequency;
wherein the inner region has a cross sectional overall height Hr as observed in an elevation view of the DRA, and a cross sectional overall width Wr in a direction parallel to the direction Ē
as observed in the plan view of the DRA; and
wherein Hr is greater than Wr/2.
