Document Type and Number:
WIPO Patent Application WO/2019/049769
Kind Code:
A1
Abstract:
This communication device has: a power transmission coil; and a power transmission circuit that wirelessly transmits power, at a prescribed power transmission frequency via the power transmission coil, to another communication device having a power reception coil coupled to the power transmission coil through an electric field and/or a magnetic field. The communication device has a reception antenna, and a reception circuit that receives, via the reception antenna, a signal transmitted from the other communication device via a transmission antenna provided to the other communication device. The communication device further has a filter circuit that suppresses a signal of the power transmission frequency inputted to the reception circuit from the reception antenna through the wireless power transmission by the power transmission circuit.
