Nanoantennas: A concept for efficient electrically small UWB devices

This paper introduces the concept of a "nanoantenna:" a device that radiates UWB impulses from the discharge of a conducting enclosure antenna. By trapping exterior electrostatic energy, a nanoantenna has the potential to radiate energy more efficiently than generally believed possible, enabling efficient millimeter scale 3.1-10.6 GHz UWB devices.
