Abstract: An antenna device comprised of dielectric elements, the device having an array of parasitic director elements which coherently focuses energy across the parasitic array. The parasitic elements are spaced less than or equal to one wavelength from each other to provide the coherent focusing, with the array thereby acting like an artificial dielectric lens. An optimal spacing or elemental length might include one-eighth (⅛) to one-quarter (¼) wavelength. A plurality of feed elements is associated with the array and provides incident energy thereon. Reflector elements might also be used to further reflect incident energy from a feed element back across the parasitic array. The various elements are switchably selectable via a switching network which might consist of diodes. The parasitic elements form a lens which provides the directionality of the antenna.
