Abstract

【課題】単純かつ安価な方式によって、ＲＦＩＤタグ周囲の状況変化をリアルタイムに検知するのに好適なＲＦＩＤタグ、及び、ＲＦＩＤタグ周囲の状況変化検知システムとその検知方法を提供する。 【解決手段】ＲＦＩＤタグ２は、アンテナ２０と、アンテナ２０を介して電波を送受信する無線通信ＩＣ２１と、ＲＦＩＤタグ周囲の物理量の変化に応じて特性が変化する素子２２Ａとを備え、素子２２Ａの特性変化によってアンテナ２０の利得が変化する。ＲＦＩＤタグ２周囲の状況が変化したときに、素子２２Ａによってアンテナ２０の利得が低下したり高まったりすることで、ＲＦＩＤタグ２は、タグ通信装置３からの質問波ＲＱに対する応答波ＡＮＳを送信できる状態と送信できない状態になるので、応答波ＡＮＳの受信の有無からＲＦＩＤタグ２周囲の状況変化をリアルタイムに検知することが可能となる。
