走査量 +/−6Deg AZ,+/−6Deg EL

この例示的な実施例では、アクティブ給電アレイ30は長さFLが約50メートル、高さFHが約1メートルであり、後述するような理由により反射器200 の頂点と円形アンテナの中心の間の約中間に位置する。理想的には、給電アレイ30は反射器200 の半径と等しい放射状のアーク上に支持される。しかし、多くの応用では、平面給電アレイが使用される可能性がある。Lバンドの0.3度の特定の方位方向のビーム幅を生成するために、方位平面の約50メートルの開口長AL(図1)が使用される。しかし高低平面では、わずかに大きい約55メートルの開口高さAH(図4)はフィ−ドアレイの妨害によって引き起こされた広がる効果をオフセットするよう選択される可能性がある。10dBの開口テ−パ−はサイドロ−ブを制御するために高低および方位平面の両者で与えられる。
