Abstract:
A transmission device 200 comprises a magnetic field antenna 250, and an electric field antenna electrically connected to the magnetic field antenna 250. The transmission device 200 can transmit an electric field signal generated on the basis of a magnetic field signal when the magnetic field antenna 250 is placed at a position that allows the reception of a magnetic field signal transmitted by another magnetic field antenna 220 of a magnetic field transmission device comprising the other magnetic field antenna 220. The electric field antenna is grounded by being electrically connected to the ground to which the magnetic field transmission device is connected.
