Abstract
Disclosed is a Radio Frequency (“RF”) Energy Harvesting System (“RFHS”). The RFHS includes a phased array antenna, a power harvesting unit, and a controller. The phased array antenna is configured to receive ambient RF energy and, in response, produce an input power signal. The power harvesting unit is in signal communication with the phased array antenna and includes a rectifier module, storage module, and power threshold module. The power harvesting unit is configured to receive the input power signal and, in response, produce a rectified power signal. The controller is in signal communication with the phased array antenna and may steer the antenna beam of the phased array antenna.
