Abstract

　広帯域で安定した動作が可能であり、高精度な実装を必要としない、ＲＦＩＤシステムに好適な無線ＩＣデバイスを得る。送受信信号を処理する無線ＩＣチップ（５）と、給電回路基板（２０）とで電磁結合モジュール（１）を構成し、給電回路基板（２０）に設けた共振回路を放射板と電磁界結合させた無線ＩＣデバイス。共振回路は、分岐電極（２２ａ），（２２ｂ）を有する線状電極（２２）と、分岐電極（２３ａ），（２３ｂ）を有する線状電極（２３）とで構成され、線状電極（２２），（２３）の一端は無線ＩＣチップ（５）の入出力端子電極（６），（６）に電気的に接続され、他端は互いに電気的に接続（短絡）されている。線状電極（２２），（２３）の他端に放射板と容量結合するための電極を備えていてもよい。
