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 sequential layered volumes Vi, i being an integer from 1 to N, wherein volume V1 forms an innermost first volume, wherein a successive volume Vi+1 forms a layered shell disposed over and at least partially embedding volume Vi, wherein volume VN at least partially embeds all volumes V1 to VN−1; wherein a portion of the dielectric material of volume VN bifurcates at least a portion of volumes V1 to VN−1; wherein the plurality of volumes of dielectric materials has a first effective dielectric constant along a first geometrical path, and has a second effective dielectric constant along a second geometrical path that is lower than the first effective dielectric constant.
