Abstract:
A wireless communication improving sheet capable of improving a possible communication distance of an IC tag for wireless communication, a wireless communication IC tag, and a wireless communication system are provided. A first spacer has an arrangement surface for arranging a wireless IC tag. An auxiliary antenna, which resonates with respect to an electromagnetic wave used for wireless communication, is provided on a surface opposite to the arrangement surface of the first spacer. A second spacer is provided on an opposite side to the first spacer with the auxiliary antenna interposed therebetween. The first spacer and the auxiliary antenna is formed with a groove (a hole) having the second spacer as the bottom.
