COMMUNICATION DEVICE, ELECTRONIC APPARATUS, MOBILE DEVICE, POWER FEEDING DEVICE, COMMUNICATOR AND COMMUNICATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2018/021042
Kind Code:
A1
Abstract:
This communication device is provided with: a cable including a pair of signal transfer media arranged in parallel to each other; an electromagnetic conversion unit electrically insulated from the pair of signal transfer media; and a communication unit which transmits/receives a communication signal. The electromagnetic conversion unit generates a magnetic flux in a direction intersecting an intersection plane crossing the center of each of the pair of signal transfer media. During transmission of a communication signal, the electromagnetic conversion unit is supplied with the communication signal from the communication unit and generates, by means of electromagnetic induction, a differential signal to the pair of signal transfer media. During reception of a communication signal, the electromagnetic conversion unit outputs, to the communication unit, the communication signal by means of a counter-electromotive force induced by a magnetic flux generated by electromagnetic induction caused by the differential signal flowing through the pair of signal transfer media. This communication device can readily provide a communication function later to an existing communication device.
