Abstract
A resonant wireless energy transfer system comprises first and second antennas made up of dual parallel wire helixes wherein the wires are terminated by short wires. Voltage controlled variable capacitors are connected into the antennas to permit progressive variation between folded dipole and normal dipole operating modes such that optimum energy transfer can be achieved between the antennas over a wide range of antenna separation distances. A vehicle battery charging system using the above-described antennas is provided including an installation which allows purchase of battery charging power by members of the general public. In-vehicle energy transfer for sensors, computers, cell phones and the like is also described.
