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.

30. A method, comprising:
-
receiving power in a remote station through a plurality of antennas, the received power being associated with an ultra-wide frequency band, each antenna from the plurality of antennas being tuned to a unique portion of the ultra-wide frequency band; and converting the received power to a DC power in the remote station. - View Dependent Claims (31, 32)

33. A method, comprising:
-
receiving power in a remote station through at least one antenna and having an LC tank circuit, the received power being associated with an RF frequency band, the at least one antenna having a physical area and an effective area greater than the physical area, the LC tank circuit being defined by a specific capacitance of a substrate on which the at least one antenna is disposed and specific electrode and inter-electrode dimensions of the at least one antenna; and converting the received power to a DC power in the remote station. - View Dependent Claims (34, 35, 36)
