1. A method of energizing a power storage device of a remote station, comprising:
- providing said remote station with an energy receiving antenna for receiving ambient energy in the form of RF frequencies falling within the range of about 2.4 to 5.875 gigahertz or about 10.0 to 66.0 gigahertz from the environment, said energy receiving antenna having an effective antenna area greater than its physical area,employing an LC tank circuit in said energy receiving antenna to establish said effective area of the antenna greater than said physical area, said LC tank circuit being formed by providing the energy receiving antenna with specific electrode and interelectrode dimensions and covering the energy receiving antenna with a film of material having a specific capacitance, thereby causing said LC tank circuit to be formed,receiving said ambient energy by said energy receiving antenna and converting said energy to DC power, andenergizing said power storage device with said DC power.

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 within frequencies of the wireless fidelity standards. The remote station preferably has at least one antenna having an effective area greater than its physical area. The invention may advantageously be used on wireless fidelity products which are energized by the power storage device.
