Abstract
A remote device powering module, system and method for providing RF power to an electronic device located in a bounded area. The remote device powering module comprises a phased array antenna and is connected to a source to convert the power to an electric signal and to apply a phase reference to the electrical signal. The electrical signal is shifted with a shifting module and phased array antenna that comprises a plurality of radiating elements generates and transmits RF power via RF waves using the phase reference and the shifted phase. The RF power is then converted by the receiver to direct-voltage to be provided to the electronic device.
