1. A dielectric resonator antenna (DRA), comprising:

  • 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 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 disposed and structured to be electromagnetically coupled to one or more of the plurality of volumes of dielectric materials; and

    an electrically conductive fence disposed circumferentially around the plurality of volumes of dielectric materials, and electrically connected with and forming part of the ground structure.
