    Abstract: A connected-DRA array including: a plurality of DRAs each having at least one volume of non-gaseous dielectric material; each of the plurality of DRAs having a proximal end and a distal end, and an overall height, H, from the proximal end to the distal end; wherein each of the plurality of DRAs is physically connected to at least one other of the plurality of DRAs via a relatively thin connecting structure being relatively thin as compared to an overall outside dimension of one of the plurality of DRAs, each connecting structure having a cross sectional overall height, h, as observed in the elevation view of the connected-DRA array, that is less than the overall height, H, of a respective connected DRA and being formed of a thin sheet of the at least one volume of non-gaseous dielectric material; wherein the thin sheet extends over a substantial portion of the connected-DRA array as observed in a plan view of the connected-DRA array.

    Abstract: A dielectric resonator antenna (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 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); a signal feed electromagnetically coupled to one or more of the plurality of volumes of dielectric materials; and, the plurality of volumes of dielectric materials defining therein a first geometrical path having a first direction that extends from the signal feed to a diametrically opposing side of the plurality of volumes of dielectric materials, and defining therein a second geometrical path having a second direction that is orthogonal to the first direction of the first geometrical path, the second geometrical path having an effective dielectric constant that is less than an effective dielectric constant of the first geometrical path.
