1. A communication system comprising:
- a transmitter including a transmission circuit unit that generates an RF signal for transmitting data and an electric-field-coupling antenna that transmits the RF signal as an electrostatic field;
a receiver including an electric-field-coupling antenna and a reception circuit unit that subjects an RF signal received by the electric-field-coupling antenna to reception processing; and
surface-wave propagating means for providing a surface wave transmission line made of a conductor that propagates a surface wave radiated from the electric-field-coupling antenna of the transmitter along a surface of the surface wave transmission line,wherein the surface wave transmission line is attached with, at least at one end thereof, an EFC electrode for electrostatic coupling with the electric-field-coupling antenna of the transmitter or the receiver to be substantially perpendicular to a traveling direction of the surface wave.
