Abstract

　本発明の目的は、無線通信用のＩＣタグの通信可能距離を改善することが可能な無線通信改善シート体、無線ＩＣタグ、アンテナおよびそれらを用いた無線通信システムを提供することである。第１のスペーサ３２は、無線ＩＣタグを結線しないで配置する配置面１０２ａを有し、第１のスペーサ３２の配置面１０２ａとは反対側の面に無線通信に用いられる電磁波に対して共振する補助アンテナ３５が設けられる。補助アンテナ３５は、共振層である第１の導体層２７および第２のスペーサ３３から成る。第２のスペーサ３３は、第１の導体層２７を挟んで第１のスペーサ３２とは反対側に設けられる。前記補助アンテナの第１の導体層２７には、不連続領域が設けられる。これによって単に通信妨害体２５の影響を排除するだけでなく、無線ＩＣタグ（アンテナ）の受信電力を増加させることができ、大きな通信距離を確保することができる。
