Communication System and Communication Apparatus
First Claim
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 magnetic field;
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; and
surface-wave propagation means for providing a surface-wave transmission line to transmit a surface wave emanating from the electric-field-coupling antenna of the transmitter with low propagation loss.
