Abstract
Description
本発明は、任意の導波管部とテーパーノッチ部からなる、2重極性化された広帯域用の放射線開口部に対して、利便性の高い給電技術(ストリップ線路給電スロット、プローブ給電スロットあるいはより一般的には給電部/導波管部境界面におけるプローブ給電開口部)を示したものである。導波管部があることにより、自立型の放射素子のグリッドと同じように、解析が円滑になる。そのようなグリッドの場合、組み立て工程における許容誤差は高くなく、製造工程における許容誤差も小さい。特に、プローブが接地面(導波管底面)を通過する必要がないため、電気的に高性能なスキャンアンテナアレイ(ESA)の取り付けをより簡単にする。
