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.

15. A method of energizing a power storage device comprising

providing a base station and a remote station having a power storage device transmitting from said base station in space to said remote station energy employing ultra-wide band frequency,

employing on said remote station antennas for receiving said ultra-wide band frequency transmitted energy to energize power storage devices on said remote station,

converting said ultra-wide band frequency transmitted energy on said remote station into DC power, and

delivering said DC power to said power storage device.

16. The method of claim 15, including

employing a said antenna formed on an electronic chip.

17. The method of claim 15, including

employing as said remote station a remote station that is printed on a substrate having conductive and insulating portions.

18. The method of claim 15, including

employing as said remote station a monolithic chip assembly which contains an antenna and the circuitry employed to effect said energy receipt and conversion.

19. The method of claim 15, including

employing as said remote station a station having printed circuitry and an antenna which is printed.

20. The method of claim 16, including

employing a said printed antenna a conductive antenna printed onto a nonconductive substrate.

21. The method of claim 19, including

employing a layer of material having a specific capacitance and electrical insulative properties on top of said antenna.
