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.
