Claim 16:
17. A transmitting antenna for wireless transfer of power, the transmitting antenna comprising:
a multi-layer, multi-turn inductor structure including:
a plurality of conductive layers comprising a plurality of conductive traces arranged in a multi-turn coil configuration, wherein each of the plurality of conductive traces have two ends, wherein each of the plurality of conductive traces provides a respective current path within the multi-layer, multi-turn inductor structure that is configured to carry induced alternating current from a respective first end of each of the plurality of conductive traces' two ends to a respective second end of each of the plurality of conductive traces' two ends, and wherein each respective pair of adjacent conductive layers within the plurality of conductive layers is separated by a respective insulating material such that a first one of the respective pair of conductive layers is on a first side of the respective insulating material and a second one of the respective pair of conductive layers is on a second side of the respective insulating material;
a first connection point at which the respective first ends of the plurality of conductive traces are electrically connected; and
a second connection point at which the respective second ends of the plurality of conductive traces are electrically connected;
wherein the multi-layer, multi-turn inductor structure is configured for wireless transfer of power within a given frequency range such that, when a power source is applied to the transmitting antenna, an alternating current flows through the plurality of conductive traces to produce an external magnetic field at a frequency within the given frequency range that is capable of inducing an alternating current at a receiving antenna that is in a near field of the transmitting antenna.
