Abstract:
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, and wherein the radio-frequency signal is transmitted by electric-field coupling to an electric-field-coupling antenna of the communication partner.
