Method and system for wireless charging using radio wave
TLDR
In this article, the authors proposed a method and system for wireless charging using a radio wave, which includes scanning the radio wave of an access point, determining an available charging frequency band among frequency bands, sending the access point a request for transmitting a charging radio wave at the charging frequency bands and switching power output from an antenna, to a battery circuit.Abstract:

Method and apparatus for harvesting energy
Abstract: An energy harvesting circuit includes one or more broadband or narrow band antennas to detect WIFI (wireless fidelity) or other RF (radio frequency) signals. The signals are rectified and voltage multiplied, and the resultant DC voltage is provided to a power management circuit. The output of the power management circuit charges a lithium battery or other storage device within the energy harvesting circuit. The energy stored in the battery or storage device is provided through a DC/DC converter circuit to a USB output connector to power or recharge the batteries of an external electronic device connected to the USB output connector of the energy harvesting circuit.
