無線ICと、
少なくとも一対の端部を有する環状電極と、
前記環状電極の一対の端部に設けられた整合部と、
前記環状電極の電流最大点に接続されたダイポール型の放射板と、
を備え、
前記無線ICは前記整合部と結合し、
前記環状電極と前記放射板とは少なくとも一部で電磁界結合していること、
を特徴とする。
無線ICと、
少なくとも一対の端部を有する環状電極と、
インダクタンス素子を含んで所定の共振周波数を有する共振回路及び/又は整合回路からなる給電回路と、
前記環状電極の電流最大点に接続されたダイポール型の放射板と、
を備え、
前記無線ICは前記給電回路と結合し、
前記環状電極と前記放射板とは少なくとも一部で電磁界結合していること、
を特徴とする。
図1及び図2に本考案の第1実施例である無線ICデバイス1Aを示す。この無線ICデバイス1Aは、所定周波数の送受信信号を処理する無線ICチップ5と、PETフィルムなどの基材20上に形成した放射板15と環状電極25にて構成されている。
前記第1実施例において、無線ICチップ5と結合する整合部は、図3(A)〜(D)に示すように、環状電極25の一対の端部26a,26bに様々な構成で配置することができる。
図4に本考案の第2実施例である無線ICデバイス1Bを示す。この無線ICデバイス1Bは、電磁結合モジュール2と、PETフィルムなどの基材20上に形成した放射板15と、環状電極25とで構成されている。電磁結合モジュール2は、所定周波数の送受信信号を処理する無線ICチップ5と、該無線ICチップ5を搭載した給電回路基板10とからなる。
図9に本考案の第3実施例である無線ICデバイス1Cを示す。この無線ICデバイス1Cは、無線ICチップ5と給電回路基板10とからなる電磁結合モジュール2、環状電極25、放射板15を備えている点は前記第2実施例と同様である。異なるのは、放射板15の端部16a,16bを環状電極25の側方に沿って折り曲げ、端部16a,16bが平面視で環状電極25を両側から挟むように配置している点である。
図10に本考案の第4実施例である無線ICデバイス1Dを示す。この無線ICデバイス1Dは、放射板15の端部を幅広部17a,17bとしたものである。他の構成は前記第2及び第3実施例と同様であり、その作用効果も第2及び第3実施例と同様である。なお、前記実施例1(図1参照)も、放射板15の両端部を幅広部17a,17bとしている。
図11に本考案の第5実施例である無線ICデバイス1Eを示す。この無線ICデバイス1Eは、放射板15の幅広部17a,17bに空隙18a,18bを形成したものである。他の構成は前記第2及び第4実施例と同様であり、その作用効果も第2及び第4実施例と同様である。特に、本第5実施例では、幅広部17a,17bに空隙18a,18bを設けることにより、放射板15の共振周波数を低くすることができ、放射板15の全体的な長さを短くでき、無線ICデバイスの放射特性を向上させながら、小型化を図ることができる。
図12に本考案の第6実施例である無線ICデバイス1Fを示す。この無線ICデバイス1Fは、環状電極25の端部26a,26bを環状電極25の内側に向けて折り曲げたものである。他の構成は前記第2及び第4実施例と同様であり、その作用効果も第2及び第4実施例と同様である。特に、本第6実施例では、端部26a,26bを環状電極25の内側に向けて配置したため、端部26a,26bを含む折曲げ部分とそれに隣接する環状電極25の線路部分とで容量が発生する。この容量と環状電極25の長さにより環状電極25の共振周波数を設計することができ、環状電極25の全体的な長さを短くでき、無線ICデバイスの小型化を図ることができる。また、環状電極25の設計自由度が向上する。
なお、本考案に係る無線ICデバイスは前記実施例に限定するものではなく、その要旨の範囲内で種々に変更することができる。
