Description
図1は、実施の形態1に係るアンテナ装置1を示す平面図である。図1において、アンテナ装置1は、例えば、誘電体基板2に設けられる。誘電体基板2は、第1の面(表面)に放射部3、給電部4および給電線路5が設けられ、第1の面とは反対側の第2の面(裏面)に接地導体8が設けられた誘電体である。放射部3は、y方向の長さAおよびx方向の幅Bの寸法を有した方形状の導体パターンであり、電磁波を放射する。例えば、RFコネクタによって給電部4に給電された電力は、給電線路5を+y方向に伝搬して放射部3に入力され、電力の一部が電磁波として放射部3から放射される。電磁波として放射されなかった残りの電力は、放射部3の内部で熱損となる。
なお、これまでの説明では、実施の形態1に係るアンテナ装置を、送信アンテナとして用いる場合を説明したが、受信アンテナとして用いても構わない。
