Abstract
周波数特性のばらつきが小さく、広帯域での動作が可能である、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)を搭載した給電回路基板(10)からなる電磁結合モジュール(1)と、放射板(25)とを備えた無線ICデバイス。放射板(25)に設けた線状の環状電極(26a),(26b)は給電回路基板(10)の表面に形成した平面電極に電磁界結合している。放射板(25)で受信された信号によって無線ICチップ(5)が動作され、無線ICチップ(5)からの応答信号が放射板(25)から外部に送信される。送受信信号の周波数は、環状電極(26a),(26b)によるインダクタンス、環状電極(26a),(26b)と平面電極との間の容量、及び、各環状電極(26a),(26b)の線間に発生する浮遊容量によって、実質的に決定される。
