Broadband multiple layer dielectric resonator antenna and method of making the same

Abstract:

A dielectric resonator antenna (DRA) includes: a plurality of volumes of dielectric materials 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, wherein the DRA when excited via an electrical signal 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 closed loop paths that are not contractible at a single point.
