WIRELESS COMMUNICATION IMPROVING SHEET BODY, IC TAG FOR WIRELESS COMMUNICATION, METHOD FOR MANUFACTURING IC TAG FOR WIRELESS COMMUNICATION, INFORMATION TRANSMITTING MEDIUM, AND WIRELESS COMMUNICATION SYSTEM

摘要

A first spacer (2) has an arrangement surface (2a) on which a wireless IC tag is arranged, and an auxiliary antenna (3) that resonates with electromagnetic wave used for wireless communication is provided on a surface opposite to the arrangement surface (2a) of the first spacer (2). A second spacer (4) is provided opposite to the first spacer (2) with the auxiliary antenna (3) interposed therebetween. The first spacer (2) and the auxiliary antenna (3) are provided with a groove (opening S) as an adjuster for resonance frequency so that the second spacer (4) forms a bottom of the groove. Application to a plurality of communication frequencies is made possible by changing an arrangement position of the wireless IC tag with respect to the adjuster.
