Stable Power Delivery Efficiency in Misaligned Wireless Power Transfer Systems Using Triffid Antennas

Stable power delivery efficiency is difficult in wireless power transfer systems without using power control. Misalignment between power transmitter and receivers makes this difficult since power is delivered axially. This paper reports on a new method for providing stable wireless power delivery efficiency in misaligned systems. By employing triffid antennas arranged in a cube stability is obtained at wide angles and all over the cubical structure.
