Abstract
Methods of constructing a wireless power receiver that uses a battery as an antenna are provided. The method includes power conversion circuitry that has a connector, the first end connected to at least a part of a battery, and the part of the battery is configured to act as an antenna and receive radio frequency (RF) power signals. The second end of the connector is opposite to the first end and connected to the power conversion circuitry. The power conversion circuitry converts the RF power signals into a direct current (DC) voltage that is used to charge the battery. Additional, some methods for constructing a wireless power receiver include a different connector between the power conversion circuitry and charging circuitry. The charging circuitry is electrically coupled with at least the part of the battery via another connector and provides DC voltage to charge the battery.
