RESONANCE-TYPE POWER TRANSMISSION SYSTEM AND TRANSMISSION DEVICE

WIPO Patent Application WO/2016/147294

A1

The present invention includes: a resonant antenna (106) that is disposed facing at least one antenna among transmission antennas (105), and resonates at the same frequency as a resonance frequency for the transmission antennas (105); a dummy load (107) that is connected to a supply path of the resonant antenna (106); a switch (108) that is capable of switching the supply path between a connected and disconnected state; a storage unit that links, to the switching states of the switch (108), magnetic flux patterns when the supply path is connected and disconnected by the switch (108) and stores the same; an antenna position acquisition unit that acquires the position of a reception antenna (201) that has approached the transmission antennas (105); and a switch control unit that switches the switch (108) from the position of the reception antenna (201) acquired by the antenna position acquisition unit, on the basis of the information stored in the storage unit.
