Abstract
A dielectric resonator antenna, DRA, includes: a ground structure; a plurality of volumes of dielectric materials disposed on the ground structure having N volumes V1 to VN, N being an integer equal to or greater than 3; a signal feed disposed and structured to be electromagnetically coupled to one or more of the plurality of volumes of dielectric materials; wherein adjacent ones of the plurality of volumes of dielectric materials have different dielectric constants with respect to each other; wherein each volume V2 to VN−1 includes a dielectric material other than air; and, wherein at least volume V1 has a cross sectional shape as observed in an elevation view with an overall height that is greater than half its respective overall width.
