Filed:

Feb 26, 2020

Appl. No.:

16/801476

Inventors:

- Chandler AZ, US
Karl E. Sprentall - Scottsdale AZ, US
Shawn P. Williams - Andover MA, US

International Classification:

H01Q 1/38
H01Q 21/06
H01Q 9/04

Abstract:

A dielectric resonator antenna, DRA, includes: an electrically conductive ground structure; a dielectric material disposed on the ground structure; a signal feed electromagnetically coupled to the dielectric material; wherein the dielectric material provides a continuous uninterrupted internal geometric path from a side of the signal feed to an opposing side through a top of the dielectric material that is configured to at least partially support a TE radiating mode; and, the dielectric material defining therein a first geometrical path having a first direction, as observed in a plan view of the DRA, and defining therein a second geometrical path having a second direction, as observed in the plan view of the DRA, that is orthogonal to the first direction of the first geometrical path, the second geometrical path having an effective dielectric constant that is less than an effective dielectric constant of the first geometrical path, the first geometrical path, relative to the second geometrical path, being a favored path for E-field lines associated with the DRA.
