ELECTRIC FIELD COMMUNICATION-MAGNETIC FIELD COMMUNICATION SHARED ANTENNA, COMMUNICATION SYSTEM, AND COMMUNICATION METHOD

摘要

PROBLEM TO BE SOLVED: To provide an electric field communication-magnetic field communication shared antenna capable of contributing to miniaturization of a terminal.SOLUTION: An electric field communication-magnetic field communication shared antenna comprises a spiral first coil 1 and a spiral second coil 2 opposed to each other. A driver 3 for electric field communication is connected between one end 1a of the first coil 1 and one end 2a of the second coil 2. A driver 4 for magnetic field communication is connected between the one end 1a of the first coil 1 and the other end 1b of the first coil 1.SELECTED DRAWING: Figure 1
