Abstract
In order to facilitate impedance matching even when using a magnetic field antenna for power transmission in a medium, this underwater wireless power supply devicewirelessly transmits energy by resonating at a frequency determined by the impedance of a power transmission antenna, the impedance of a power receiving antenna, and the impedance of a good conductor medium. The power transmission antennaand the power receiving antennahave multiple antenna coils, and multiple resonant antenna unitstohaving at least one dielectricarranged between the multiple antenna coils, and, at least one of the multiple resonant antenna unitstois provided with a load adjustment mechanismfor adjusting the load.
