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。
