Claim 0:
1. A wireless power transfer system comprising:
a wireless power transmission system comprising:
one or more electrical components configured for generating wireless power signals;
a transmission antenna comprising:
a source coil comprised of a first conductive wire, the source coil including a first outer turn and a first inner turn, the source coil configured to connect to one or more electronic components for transmitting the wireless power signals, the first conductive wire beginning at a first source terminal associated with a beginning of the first outer turn and the first conductive wire ending at a second source terminal associated with an ending of the first inner turn, the first conductive wire disposed such that a source current flows in a first source direction through the first outer turn and a second source direction through the first inner turn, the second source direction substantially opposite of the first source direction, and
a transmission internal repeater coil comprised of a second conductive wire, wherein the transmission internal repeater coil is adjacent to the source coil and configured to relay the wireless power signals from the source coil, the transmission internal repeater coil including a second outer turn and a second inner turn, the transmission internal repeater coil further configured to have a repeater current induced in the second outer turn and the second inner turn, the second conductive wire disposed such that the repeater current flows in a first repeater direction through the second outer turn and a second repeater direction through the second inner turn, the second repeater direction substantially opposite of the first repeater direction; and

a wireless power receiver system comprising:
a rectifier and
a receiver antenna, the receiver antenna including
a receiver coil, the receiver coil configured to receive one or both of the wireless power signals and repeated wireless power signals and provide the wireless power signals and repeated wireless power signals to the rectifier and
a receiver internal repeater coil, the receiver internal repeater coil configured to receive the wireless power signals and transmit the wireless power signals to the receiver coil as the repeated wireless power signals.
