Communication system and communication apparatus
First Claim
1. A communication apparatus comprising:
- a communication circuit unit configured to process a radio-frequency signal for transmitting data; and
an electric-field-coupling antenna configured to establish electric-field coupling to a communication partner facing the communication apparatus at a very short distance,wherein the electric-field-coupling antenna includes a coupling electrode and a resonating section including a distributed-constant circuit configured to strengthen electrical coupling between the coupling electrode of the communication apparatus and a coupling electrode of the communication partner, the electric-field-coupling antenna being mounted on a printed circuit board on which a circuit module constituting the communication circuit unit configured to process the radio-frequency signal for transmitting data is provided, andwherein the radio-frequency signal is transmitted by electric-field coupling to an electric-field-coupling antenna of the communication partner.

Abstract
A communication system includes the following elements: a transmitter including a transmission circuit unit configured to generate an RF signal for transmitting data and an EFC antenna configured to transmit the RF signal as an electrostatic field or an induced electric field; and a receiver including an EFC antenna and a reception circuit unit configured to receive and process the RF signal received by the EFC antenna. The EFC antennas of the transmitter and the receiver each include a coupling electrode and a resonating section including a distributed-constant circuit configured to strengthen electrical coupling between the coupling electrodes. The RF signal is transmitted by electric-field coupling between the EFC antennas, facing each other, of the transmitter and the receiver.
