Abstract
A wireless communication-improving sheet member for increasing a possible communication distance of an IC tag for wireless communication, a wireless IC tag, an antenna, and a wireless communication system. The sheet member may include a first spacer having an arrangement face on which the wireless IC tag is disposed without a wired connection, and an auxiliary antenna is disposed on the first spacer on an opposite side to the arrangement face, the auxiliary antenna resonating with electromagnetic waves used in the wireless communication. The auxiliary antenna has a first conductor layer as a resonant layer and a second spacer. The second spacer is disposed on an opposite side to the first spacer with the first conductor layer interposed therebetween. A discontinuous area is disposed in the first conductor layer of the auxiliary antenna.
