Each rectenna board includes, in part, a multitude of receive antennas for receiving the RF signal. The rectenna boards are adapted to enclose the rechargeable battery when the rechargeable battery is positioned over the first board. The second board is adapted to engage with the rectenna boards to cover a top portion of the rechargeable battery.
