Title:
ELECTRICALLY SMALL ANTENNA
Document Type and Number:
WIPO Patent Application WO/2010/011391
Kind Code:
A3
Abstract:
An electrically small antenna (ESA) for resolution of subwavelength features is disclosed. The ESA (100) 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 (120). Such an antenna may include phase sensitive current injection in the metamaterial resonant structures for loss-compensation.
