Claim 18:
19. An antenna for wireless power transmission comprising:
a source coil comprised of a first conductive wire, the source coil including a first plurality of outer turns and a first plurality of inner turns, 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 plurality of outer turns and the first conductive wire ending at a second source terminal associated with an ending of the first plurality of inner turns, the first conductive wire disposed such that a source current flows in a first source direction through the first plurality of outer turns and a second source direction through the first plurality of inner turns, 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 plurality of outer turns and a second plurality of inner turns, the internal repeater coil configured to have a repeater current induced in the second plurality of outer turns and the second plurality of inner turns, the second conductive wire disposed such that the repeater current flows in a first repeater direction through the second plurality of outer turns and a second repeater direction through the second plurality of inner turns, the second repeater direction substantially opposite of the first repeater direction; and
a repeater tuning system in electrical connection with a beginning of the plurality of second outer turns and an ending of the plurality of second inner turns, the repeater tuning system positioned inward of the plurality of second outer turns.
