Abstract
Systems and methods are provided for enabling ambient radio frequency (RF) energy to be harvested with a device. In an embodiment, wideband phased array antennas in the device efficiently harvest ambient RF energy over a broad electromagnetic spectrum, and circuitry adapts this RF energy into DC power for battery charging or energy storage. In an embodiment, the device is a modularly connected/disconnected, passive, wireless RF-to-DC adapter accessory that can ultimately be used to supply power to an electric apparatus and/or transporter.
