Summary:To avoid interference between antenna patterns while realizing compactness in a configuration in which identification information can be recognized using a plurality of antenna patterns having mutually different resonant frequencies.SOLUTION: In a configuration in which a plurality of antenna formation regions 51 to 62 are provided in the base material 10, to which mutually different resonance frequencies are assigned and antenna patterns 11 to 22 in which resonance peaks appear at the resonance frequencies are formed, in the antenna formation regions 51 to 62, assigned resonance frequencies are shifted stepwise. In this step, antenna formation areas separated by two or more in high and low directions of frequency are arranged physically adjacent to each other.SELECTED DRAWING: Figure 5 【課題】共振周波数が互いに異なる複数のアンテナパターンを用いて識別情報を認識可能とする構成において、小型化を実現しながらアンテナパターン間の干渉を回避する。【解決手段】互いに異なる共振周波数が割り当てられ、該共振周波数にて共振ピークが発現するアンテナパターン１１〜２２が形成される複数のアンテナ形成領域５１〜６２がベース基材１０に設けられた構成において、アンテナ形成領域５１〜６２は、割り当てられた共振周波数が段階的にずれており、その段階が周波数の高低方向に２つ以上離れたアンテナ形成領域どうしが物理的に隣接して配置されている。【選択図】図５
