Claims (1)
- 電磁波を反射する複数の反射鏡と、
前記複数の反射鏡に含まれる反射鏡別に設置された、電磁波を放射する一次放射器を複数、有する一次放射器群、をそれぞれ含む複数の給電部クラスタと、備え、
各一次放射器群からの電磁波を対応する前記反射鏡に反射させることにより、平面的に隣接して配置された複数のエリアのうち互いに隣接する3つ以上のエリアに対し、互いに異なる一次放射器群からの電磁波を対応する反射鏡に反射させて形成したアンテナビームをそれぞれ照射し、
前記各一次放射器群に含まれる複数の一次放射器の配置は、前記アンテナビームを照射させる前記複数のエリアのそれぞれに対応させた配置になるように決定されており、
前記複数の給電部クラスタのそれぞれの各前記一次放射器は、交互に隣接するアンテナビームの前記複数のエリアに対応させて同一の前記給電部クラスタが有する全ての前記一次放射器の前記エリアが互いに隣接しないように配置される、
アンテナ装置。
