Communication system
First Claim
1. A surface-wave propagation device comprising a plurality of linear surface-wave transmission lines propagating a surface wave that is a longitudinal wave component of an electromagnetic wave radiated by electrostatic coupling from an electrical-field coupling electrode disposed in a communication apparatus, wherein a bundle end of the linear surface-wave transmission lines closed to an electrical-field coupling electrode is formed by bundling a plurality of wire rods at one end, and the bundle of the wire rods are undone at the other end of the linear surface-wave transmission lines closed to an electrical-field coupling electrode.

Abstract
A communication system includes: a transmitter including a transmission circuit unit generating an RF signal for transmitting data and an electrical-field coupling antenna transmitting the RF signal as an electrostatic field or an induction field; a receiver including an electrical-field coupling antenna and a reception circuit unit subjecting an RF signal received by the electrical-field coupling antenna to reception processing; and a surface-wave propagation device including a plurality of linear surface-wave transmission lines for propagating a surface wave radiated from the electrical-field coupling antenna of the transmitter.
