SYSTEM AND METHOD FOR LONG-RANGE WIRELESS POWER TRANSFER

A long-range wireless power transfer system is disclosed. The system comprises at least a transmitting antenna that is configured to receive electric power from a power source as an input, convert the input electric power into electromagnetic energy, and radiate the electromagnetic energy into free space as a directional beam that is a collimated or substantially collimated beam. The rectifying antenna is positioned or configured to be positioned at a distance from the transmitting antenna . The rectifying antenna is configured to receive the directional beam and convert the electromagnetic energy into electricity. In certain embodiments, the system utilise one or more phase correcting devices to maintain the directional beam as the collimated beam and to increase a range to which the directional beam is maintained as the collimated or substantially collimated beam.
