Electronic circuit system, electronic circuit device, and wireless communication device in which antennas are selected to be paired for wireless communication and the selected antennas are connected to the electronic circuits
Provided is an electronic circuit system that reduces at least one of a constraint on a positional relation between two electronic circuit devices and a constraint on the number and an arrangement of coils included in each device, when close-coupled wireless communication is established. In the electronic circuit system, wireless communication utilizing inductive coupling between antennas is established between first and second electronic circuit devices. The second electronic circuit device includes an electronic circuit, a plurality of antennas, a connection information generation unit and a connection switching unit. The connection information generation unit selects one of the plurality of antennas to be paired with an antenna included in the first electronic circuit device for use in wireless communication, and the connection switching unit switches one or more of the plurality of antennas to be connected to the electronic circuit.
