Wireless Power Transmission Antenna with Internal Repeater and In-Coil Tuning

A wireless power transmission system comprising:

• one or more electrical components configured for generating signals for one or both of wireless power transmission and wireless data transmission;
• 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 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;
• 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,
• wherein the source coil is configured to wirelessly transmit wireless power signals generated by the one or more electrical components to the internal repeater coil and a wireless receiver system, and
• wherein the internal repeater coil is configured to receive the wireless power signals and transmit repeated wireless power signals to the wireless receiver system, the repeated wireless power signals based on the received wireless power signals.
