Abstract

　無線デジタル信号をベースバンド伝送で直接的に無線送受信する場合に、矩形波形の高調波成分が基本周波数成分より減少することによって生じる波形歪みを低減するために、アンテナ装置は、裏面に接地導体（２）を形成してなる誘電体基板（１）と、誘電体基板（１）の表面に形成された放射導体（３）とを含む。放射導体（３）は、アンテナ装置を励振したときの電界により定義される電界面と交差する放射導体（３）の辺に形成された切欠き（５，６）を形成することにより、放射導体（３）の給電点９を介して無線デジタル信号をベースバンド伝送で直接的に送受信するとき、伝送された無線デジタル信号の波形歪みを低減させる。
