Abstract
The present invention provides apparatus and an associated method for remotely energizing power storage devices. Energization may preferably be effected through the use of RF energy from a base station, ambient energy or ultra-wide band energy. The remote station preferably has at least one antenna having an effective area greater than its physical area. The system may have an antenna and associated circuitry provided on an electronic chip such as a monolithic chip or on a printed circuit with a suitable substrate.
