Problems solved by technology

That is, when the transmitter and receiver are close to each other, the non-contact power supply unit and the high-frequency coupler cannot face each other at the same time, so power supply and high-speed data transmission cannot be performed simultaneously via a single operation by the user.

Embodiment Construction

[0052] Hereinafter, preferred embodiments of the present disclosure will be described in detail with reference to the accompanying drawings. Note that, in this specification and the appended drawings, structural elements that have substantially the same function and structure are denoted with the same reference numerals, and repeated description of these structural elements is omitted.

[0053] A composite communication device, in which non-contact power supply using electromagnetic induction and communication using proximity wireless transmission are combined, can simultaneously perform power supply and high-speed data transmission without using a cable. Contactless power supply is a technique known to those skilled in the art (for example, see International Publication WO2007 / 080820). The principle of short-range wireless transmission technology will be described.

[0054] In short-range wireless transmission, the antenna element used is Figure 13 high frequency coupler s...

Abstract

The invention discloses a communication apparatus and a communication system. The communication apparatus includes a magnetic sheet that includes an opening, a non-contract power supply coil that is disposed on the magnetic sheet, a high-frequency coupler that 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 a communication circuit unit that processes a high-frequency signal transmitted to and received from the coupling electrode.

Description

technical field [0001] The present technology relates to a communication device and a communication system that perform communication by short-range wireless transmission using weak UWB signals, and more particularly, to short-range wireless transmission combined with non-contact power supply using electromagnetic induction, magnetic field resonance, and the like Communication devices and communication systems for communication. Background technique [0002] Examples of non-contact communication technologies suitable for high-speed communication include short-range wireless transfer technology "TransferJet" (trademark) (see, eg, www.transferjet.org / ja / index.html (June 23, 2011)). The short-range wireless transmission technology basically uses a scheme of transmitting a signal through the coupling effect of an induced electric field. A communication device using the short-range wireless transmission technology includes a communication circuit unit that processes a high-frequ...
