Abstract:
1. A communication apparatus comprising: a magnetic sheet that includes an opening; a non-contact power supply coil that is disposed on the magnetic sheet; a high-frequency coupler that is mounted on a board, wherein the high-frequency coupler includes a coupling electrode, a ground, and a resonance unit configured to increase an amount of current flowing into the coupling electrode, and is configured such that the coupling electrode appears on the magnetic sheet via the opening, and wherein the magnetic sheet blocks magnetic flux generated from the non-contact power supply coil from reaching the board from the ground or the resonance unit of the high-frequency coupler; a communication circuit unit that processes a high-frequency signal transmitted to and received from the coupling electrode; and a connector configured to mount a signal line cable connecting the coupling electrode to the communication circuit unit, wherein the connector is disposed inside the non-contact power supply coil and appears together with the coupling electrode on the magnetic sheet via the opening, and wherein the signal line cable mounted on the connecter crosses an upper surface of the non-contact power supply coil to be connected to the communication circuit unit.
