Abstract

A sheet material improved for wireless communication, a wireless IC tag and an antenna which can increase a communication coverage distance of an IC tag for wireless communication, as well as a wireless communication system using those means. A first spacer (32) has an arrangement surface (102a) where a wireless IC tag is arranged without wiring, and an auxiliary antenna (35) is provided which resonates to the electromagnetic waves in use for wireless communication on the opposite surface of the arrangement surface (102a) on the first spacer (32). The auxiliary antenna (35) consists of a first conductor layer (27) served as a resonating layer and a second spacer (33). The second spacer (33) is provided on the opposite side of the first spacer (32) with the first conductor layer (27) between. A discontinuous region is provided on the first conductor layer (27) of the auxiliary antenna. Such an arrangement can not only eliminate the effect of a communication obstacle material (25), but also increase the receiving power of the wireless IC tag (antenna) to assure greater communication coverage distance.
