BROADBAND MULTIPLE LAYER DIELECTRIC RESONATOR ANTENNA AND METHOD OF MAKING THE SAME
First Claim
1. A dielectric resonator antenna (DRA), comprising:
- an electrically conductive ground structure;
a plurality of volumes of dielectric materials disposed on the ground structure comprising N volumes, N being an integer equal to or greater than 3, disposed to form successive and sequential layered volumes V(i), i being an integer from 1 to N, wherein volume V(1) forms an innermost volume, wherein a successive volume V(i+1) forms a layered shell disposed over and at least partially embedding volume V(i), wherein volume V(N) at least partially embeds all volumes V(1) to V(N−
1); and
a signal feed disposed and structured to be electromagnetically coupled to one or more of the plurality of volumes of dielectric materials;
wherein the DRA when excited by an electrical signal on the signal feed is configured to produce a far field 3D radiation pattern that occupies a topological space corresponding to a two-element homotopy group defined by a family of closed loop paths that are contractible at a single point, and by a family of the closed loop paths that are not contractible at a single point.
