WIPO Patent Application WO/2014/141906
Kind Code:
A1
Abstract:
This compact integrated circuit (IC) tag is provided with an ultra-compact IC tag and laminated coils. The ultra-compact IC tag has a strip-shaped coil antenna constituting a resonant circuit. The laminated coils comprise: a spiral-shaped laminated coil obtained by winding a coil around an axis a plurality of times in a spiral shape in the same plane; and an open coil in which the starting point of the winding and the ending point of the winding of the laminated coil are not connected. The ultra-compact IC tag and each of the laminated coils are electrically disconnected, and are configured in such a manner that the antenna surface of the laminated coil which is wound a plurality of times is parallel to the antenna surface of the laminated coil and the antenna surface of the ultra-compact IC tag. The outside of the spiral-shaped laminated coil is covered with an insulating member.
