Abstract
A recovery unit adapted to receive a mobile device includes a multitude of planar antennas disposed along at least one of bottom or top surfaces of the recovery unit, a rectifying circuit adapted to convert an RF power received by the planar antennas to a DC power, an energy storage unit adapted to store the DC power, and a wireless communication circuit adapted to communicate with a power generating unit generating the RF power. The recovery unit is further adapted to supply the DC power to the mobile device. The recovery unit may further include a multitude of edge antennas disposed along exterior edges of the recovery unit. The recovery unit may further include at least one inductive coil to supply power to the mobile device when an AC power is applied to the inductive coil. The AC power may be generated from the received RF power.
