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

Abstract:

A dielectric resonator antenna (DRA), includes: 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 first 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); wherein a portion of the dielectric material of volume V(N) bifurcates at least a portion of volumes V(1) to V(N-1); and a signal feed electromagnetically coupled to one or more of the plurality of volumes of dielectric materials.
