Claims (3)
- 平行長辺と短辺とを有する環状導体の一方の長辺に無線タグ用ICチップを介在接続すると共に、他方の長辺をほぼ3等分した二つの給電点にそれぞれ前記各短辺の外側に対称配置した蛇行導体と先端容量装荷導体とを順次直列に接続して半波長ダイポールアンテナを構成する一方、このアンテナに前記給電点を有する長辺を含めて方形のループアンテナの1辺を非接触結合させることで、このループアンテナによる送受電磁波中の磁界波を前記ダイポールアンテナによる送受電磁波中の電界波に加えて送受信可能に構成した無線タグ用複合アンテナ。
- 平行長辺と短辺とを有する環状導体の一方の長辺に無線タグ用ICチップを介在接続すると共に、他方の長辺をほぼ3等分した二つの給電点にそれぞれ前記各短辺の外側に対称配置した蛇行導体と先端容量装荷導体とを順次直列に接続して半波長ダイポールアンテナを構成する一方、前記給電点を有する長辺に方形のループアンテナの1辺を導通接続することで、このループアンテナによる送受電磁波中の磁界波を前記ダイポールアンテナによる送受電磁波中の電界波に加えて送受信可能に構成した無線タグ用複合アンテナ。
- ループアンテナの前記1辺の幅を他の3辺の幅よりも小さい長辺の幅と同等にすることで、前記1辺の電流密度を他の3辺の電流密度よりも強めてダイポールアンテナに加わるループアンテナの送受電磁波中の磁界波を強めたことを特徴とする請求項1または請求項2に記載の無線タグ用複合アンテナ。
