Patent ID: 8879995

Claim:
A remote device powering module adapted to be connected to a source for providing power via Radio Frequency (RF) waves to an electronic device located in a bounded area, the device comprising: a transmitter for transmitting RF power to the electric device, the transmitter comprising: at least one connector for providing an electrical connection with the power source; a conversion circuit for converting power from the source to an electrical signal having a reference phase; a phase shifter module for shifting the reference phase of the electrical signal; and a phased array antenna mounted to the transmitter and having a plurality of radiating elements adapted to transmit the electrical signal at a plurality of phases, the phase shifter module adapted to determine, prior to transmission of the electrical signal as RF power from the phased array antenna to the electronic device, a phase shift increment between at least a pair of the plurality of radiating elements to cause at least one of a constructive radiation intensity in a first direction and a destructive radiation intensity in a second direction upon radiation being emitted by the plurality of radiating elements, and to apply the phase shift increment to the reference phase of the electrical signal to create a shifted electrical signal provided to at least one of the at least pair of plurality of radiating elements.
