PROBLEM TO BE SOLVED: To provide a wireless power transmission technique for transferring energy in high power transfer and/or with high efficiency.SOLUTION: In a power transmitter assembly 100, a high-frequency generator 104 which received power from an AC plug 102 couples energy to an antenna 110 which is a resonant antenna. The antenna includes an induction loop 111. The induction loop is inductively coupled to a high Q resonant antenna unit 112. A high Q resonant antenna includes N coil loops 113. Each coil loop has a radius A. A variable capacitor 114 is connected in series to the coil loop to form a resonance loop. A receiver 150 includes a receiving antenna 155 placed apart from only by distance d from a transmitting antenna. The receiving antenna is a high Q resonance coil antenna 151 coupled to an inductively coupled loop 152 and including a coil part and a capacitor. An output of the inductively coupled loop is rectified by a rectifier 160, and applied to a load. |
