<p>A COMMUNICATION SYSTEM INCLUDES THE FOLLOWING ELEMENTS: A TRANSMITTER (10) INCLUDING A TRANSMISSION CIRCUIT UNIT (11) CONFIGURED TO GENERATE AN RF SIGNAL FOR TRANSMITTING DATA AND AN EFC ANTENNA CONFIGURED TO TRANSMIT THE RF SIGNAL AS AN ELECTROSTATIC FIELD OR AN INDUCED ELECTRIC FIELD; A RECEIVER (20) INCLUDING AN EFC ANTENNA AND A RECEPTION CIRCUIT UNIT (21) CONFIGURED TO RECEIVE AND PROCESS THE RF SIGNAL RECEIVED BY THE EFC ANTENNA; AND AN IMPEDANCE SNATCHING UNIT CONFIGURED TO MAKE AN IMPEDANCE OF THE EFC ANTENNA OF THE TRANSMITTER (10) EQUAL TO AN IMPEDANCE OF THE EFC ANTENNA OF THE RECEIVER (20). THE RF SIGNAL IS TRANSMITTED BY ELECTRIC-FIELD COUPLING BETWEEN THE EFC ANTENNAS, FACING EACH OTHER, OF THE TRANSMITTER (10) AND THE RECEIVER (20).</p> |
