ABSTRACT:
An electrically small antenna (ESA) for resolution of subwavelength features is disclosed. The ESA is on the order of meters and has an efficient transmit/receive capability. The ESA is 1/10 of the length of the equivalent dipole length, and may be scaled down to 1/10,000. The ESA includes a metamaterial shell. Such an antenna may include phase sensitive current injection in the metamaterial resonant structures for loss-compensation.
