PROBLEM TO BE SOLVED: To achieve high performance non-contact remote electric power transmission.SOLUTION: By using two antennas having a pair of different feeding points, electric power transmission is carried out using a first polarization with a first pair of feeding points, and a control signal is transmitted using polarization orthogonal to the first polarization with a second pair of feeding points to control impedance of the two antennas with the control signal. |
