To provide an RFID tag which is not influenced by a dielectric constant of a carbon black contained in a rubber and a rubber itself when it is used by being embedded in a rubber product, a tire with built-in the RFID tag, and a resonance frequency of the RFID tag.MEANS FOR SOLVING THE PROBLEM: An RFID tag 22 contains: a wave director 13; a folding radiator 10; and a tag with built-in an antenna 11. The folding radiator 10 and the tag with built-in the antenna 11 are distributed on the same print circuit board 21, and the folding radiator 10 comprises: a coil 12 less than one turn having an open part and a synchronization semi fixing capacitor 14. The coil 12 less than one turn and the synchronization semi-fixing capacitor 14 configure a resonance circuit, the wave director 13 is a substantially linear conductor in which one end is connected to one open part of the coil 12 less than one turn, and the coil 12 less than one turn and an antenna of the tag with built-in the antenna 11 are electromagnetic field coupled.SELECTED DRAWING: Figure 2

    【課題】ゴム製品に埋め込んで使用される場合に、ゴムに含まれるカーボンブラックと、ゴム自体の比誘電率によって影響されないRFIDタグ、RFIDタグ内蔵タイヤ、およびRFIDタグの共振周波数の調整方法を提供する。【解決方法】RFIDタグ22は、導波器13と、折り返し放射器10と、アンテナ内蔵タグ11と、を含み、折り返し放射器10とアンテナ内蔵タグ11とは同一のプリント基板21に配設され、折り返し放射器10は開放部を有する1ターン未満のコイル12と同調半固定コンデンサ14とを備え、1ターン未満のコイル12と同調半固定コンデンサ14とは共振回路を構成し、導波器13は、1ターン未満のコイル12の一方の開放部の端部に一端が接続された略直線状の導体であって、1ターン未満のコイル12とアンテナ内蔵タグ11のアンテナとが電磁界結合されている。【選択図】図2
