Abstract
Description
Selective Surface:FSS)はセカンダリ・リフレクタとして使用される。セカンダリ・リフレクタは双曲面として設計され、双曲面の虚焦点とプライマリ・リフレクタの実焦点とはオーバーラップし、異なる周波数の給電部が双曲面の虚焦点及び実焦点にそれぞれ配置される。セカンダリ・リフレクタは、虚焦点に位置する低周波給電部により伝送される電磁波を伝送し、実焦点に位置する高周波給電部により伝送される電磁波を反射し、デュアル・バンド多重機能を実現する。
Telecommunications Standards Institute:ETSI)により指定される放射パターン包絡線(Radiation
Pattern Envelope:RPE)テンプレートを満足することができない。しかしながら、FSS310のアレイ配置方向が入射電磁波の偏向方向に対して45度又は135度である場合、誘発される電流が、上記2つの方向におけるギャップの両側におけるメタル上で生成され、このケースで形成される散乱電磁波は、入射電磁波の偏向方向に対して対称的である。このケースにおいて、送信された電磁波がFSSを通過した後に取得されるパターン変化の結果が図6に示されている。これは、送信された電磁波のビーム形状の逸脱度を減らし、送信される電磁波のサイド・ローブ高さを減らし、ETSIにより指定されるRPEテンプレートを満足する。更に、既存の配置方向(0度又は90度)との比較において、エネルギがより集中し、ホーン・アンテナ300の指向性が改善され、周辺サイトに対する干渉が削減される。
