Abstract

　薄型化に対応可能で、自己インダクタンスと相互インダクタンスとの比率がより大きくなるように適正化することで、相対的に相互インダクタンスが小さくて互いに重なり合っても及ぼし合う影響を小さくできるコイルアンテナを提供することを目的とし、チップコイル等の部品を用いることなく、主配索パターン１２を形成する導線１６を用いて巻線パターン１４を形成することで、当該コイルアンテナ１０を用いる製品の薄型化によるフレキシブル化に対応でき、また、ループ状をなす主配索パターン１２に対して分散され、主配索パターン１２と比較して巻回形状が十分小さくなるように導線１６により形成された巻線パターン１４を有するよう配索パターンを工夫することで、自己インダクタンスと相互インダクタンスとの比率が、より大きくなるように効率よく適正化し、相対的に相互インダクタンスが小さくなるようにした。
