    • The present invention provides a wireless tag to be attached onto a disc-shaped recording medium including first and second regions. The first region, made of a nonconductive member, is disposed on the inner radial part of the recording medium, whereas the second region, including a conductive member, is disposed on the outer radial part of the recording medium. The wireless tag includes: a feed section connected to a wireless IC chip; a conductive plate including a slot therein; and a slot antenna for receiving power from the feed section. The conductive plate is formed for at least partially overlapping with the second region when the wireless tag is attached onto the inner radial part of the recording medium. The slot has a length set for obtaining an inductance enough to cause a resonance between the slot antenna and the wireless IC chip at a predetermined wireless frequency.
    • 本发明提供一种要附着到包括第一和第二区域的盘形记录介质上的无线标签。 由非导电构件制成的第一区域设置在记录介质的内部径向部分上,而包括导电构件的第二区域设置在记录介质的外部径向部分上。 无线标签包括:连接到无线IC芯片的馈电部分; 导电板,其中包括槽; 以及用于从馈电部分接收电力的缝隙天线。 当无线标签附着到记录介质的内部径向部分上时,导电板形成为与第二区域至少部分重叠。 该槽具有一定的长度,用于获得足以在预定无线频率下在缝隙天线与无线IC芯片之间引起谐振的电感。
