  "textContent": "In order to facilitate impedance matching even when using a magnetic field antenna for power transmission in a medium, this underwater wireless power supply device wirelessly 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 antenna and the power receiving antenna have multiple antenna coils , and multiple resonant antenna units to having at least one dielectric arranged between the multiple antenna coils , and, at least one of the multiple resonant antenna units to is provided with a load adjustment mechanism for adjusting the load.",
