1. A metamaterial lens for a radio frequency (RF) antenna comprising a plurality of adjacent time-delay unit (TDU) cells, each TDU cell comprising:
a dielectric material;
an inductive rectangular wire loop on a first side of the dielectric material arranged about a perimeter of the TDU cell; and
a capacitive patch on a second side of the dielectric material and positioned within the perimeter of the TDU cell.
