Claims (1)
- 直進性の高い周波数帯の電波を受けて反射させる反射面を備えた電波反射体であって、
前記反射面は、目的とする電波の波長λを直径とした外周縁に連なる曲面を有する拡散起生部を、平坦な反射基準面に複数設けることで、拡散反射構造とし、
前記反射面の拡散反射構造は、全ての拡散起生部が隣接する他の拡散起生部との隣接距離Lが等しくなるよう整列配置し、且つ、拡散起生部の特性に基づき定めた隣接距離係数kと波長λとの積で隣接距離Lを求めるようにし、
前記反射面に設ける拡散起生部は、目的とする電波λを直径とした半球状の窪みである拡散起生凹部と、目的とする電波λを直径とした半球状の起伏である拡散起生凸部とを含み、
前記反射面の拡散反射構造は、前記拡散起生凹部と前記拡散起生凸部とが必ず隣り合うように配置し、
前記隣接距離係数kは、0.69<k<0.71の範囲内で設定することを特徴とする電波反射体。
