    • In one embodiment of the present invention, an object of the invention is to provide a wireless communication-improving sheet member capable of increasing a possible communication distance of an IC tag for wireless communication, a wireless IC tag, an antenna, and a wireless communication system. A first spacer includes an arrangement face on which 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 includes 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. Thus, it is possible to not only eliminate influence of a communication-jamming member, but also increase received electrical power of a wireless IC tag (antenna), and ensure a long communication distance.
    • 在本发明的一个实施例中,本发明的一个目的是提供一种能够增加用于无线通信的IC标签,无线IC标签,天线和无线通信的可能通信距离的无线通信改善片材 系统。 第一间隔件包括布置面,无线IC标签在该布置面上没有布线连接,辅助天线布置在与布置面相反的一侧上的第一间隔件上,辅助天线与电磁波共振 无线通信。 辅助天线包括作为共振层的第一导体层和第二间隔物。 第二间隔件设置在与第一间隔物相反的一侧上,其间插入第一导体层。 不连续区域设置在辅助天线的第一导体层中。 因此,不仅可以消除通信干扰构件的影响,而且可以增加无线IC标签(天线)的接收电力,并且确保长的通信距离。
