Abstract:
1. A communication system comprising: a transmitter including a transmission circuit unit configured to generate a radio-frequency signal for transmitting data and an electric-field-coupling antenna configured to transmit the radio-frequency signal as an electrostatic field or an induced electric field; and a receiver including an electric-field-coupling antenna and a reception circuit unit configured to receive and process the radio-frequency signal received by the electric-field-coupling antenna, wherein the electric-field-coupling 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, and wherein the radio-frequency signal is transmitted by an electric-field longitudinal wave component of electric-field coupling between the electric-field-coupling antennas, facing each other, of the transmitter and the receiver.
