ELECTRONIC CIRCUIT SYSTEM, ELECTRONIC CIRCUIT DEVICE, AND WIRELESS COMMUNICATION DEVICE

摘要

Disclosed is an electronic-circuit system that reduces a restriction on at least one of a restriction on a positional relationship of two electronic-circuit devices, and a restriction related to a number of coils of a device and a location, when implementing close-coupled wireless communications. The electronic-circuit system implements wireless communication between a first-electronic circuit device and a second-electronic circuit device using inductive coupling between antennae. The second-electronic circuit device is equipped with an electronic circuit, a plurality of an antenna, a connection-information generating unit and a connection switching unit. The connection-information generation unit selects an antenna to use in wireless communication by paring with an antenna of the first-electronic circuit device of the plurality of antenna, and connects with an electronic circuit by the connection switching unit.
