<p>A communication device comprises: a first transmitting and receiving element that generates and detects a magnetic field; and a second transmitting and receiving element that detects a magnetic field generated by the first transmitting and receiving element and generates a magnetic field detectable by the first transmitting and receiving element. The first and second transmitting and receiving elements transmit and receive signals through magnetic field coupling between ends of the first element second transmitting and receiving elements.</p> |
