Claim 0:
1. An antenna for wireless power transmission 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 wireless power transfer, 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;
an internal repeater coil comprised of a second conductive wire, the internal repeater coil including a second outer turn and a second inner turn, the internal repeater coil 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 repeater tuning system in electrical connection with a beginning of the second outer turn and an ending of the second inner turn, the repeater tuning system positioned inward of the second outer turn.
