Abstract

　本発明は小型で且つ誘電率の小さな安価な誘電体基板を用いてＬＳＩチップとループアンテナの整合が取れ且つ金属への貼付けが出来るタグアンテナを提供することを目的とする。本発明のループアンテナは直方体状の誘電体基板１２と誘電体基板１２の２対の対向面１３－１と１３－２及び１４－１と１４－２を被覆する金属から成るループ部１５を有する。ループ部１５は面積の広い１対の対向面のうち一方の面１３－１の中心部に余白部を残して形成される。この余白部にはＬＳＩチップとの給電点１６とこの給電点１６と並列にループ部１５に接続されたキャパシタンス部分１７（１７－１、１７－２）が形成されている。キャパシタンス部分１７は小型のＬＳＩチップでもアンテナと整合するようにＬＳＩチップの内部キャパシタンスを補うために設けられ、一方の長さＳ２の凸部が他方の凹部内に間隙Ｇ２を有して配置されて大きなキャパシタンスを形成する。
