Abstract:
A transmission apparatus transmits electric power via a medium that is present between the transmission apparatus and a receiving apparatus. The transmission apparatus includes: an antenna; and a power transmission circuit that outputs electric power via the antenna of the transmission apparatus, the electric power having a first resonance frequency determined by an impedance of the medium, an impedance of the antenna of the transmission apparatus, and an impedance of an antenna of the receiving apparatus.
