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

Abstract:

A method for the manufacture of a dielectric resonator antenna (DRA) or array of DRAs, the DRA having: an electrically conductive ground structure; a plurality of volumes of dielectric materials disposed on the ground structure having 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. The method including molding at least one of the plurality of volumes of the dielectric material, or all of the volumes of the dielectric material.
