Abstract

Antenne à plans parallèles du type Pill-Box ou fromage dont la partie cylindro-parabolique (10) est constituée par un réflecteur semi-transparent et dont le plan focal est constitué par un réflecteur polariseur. (11)
Le réflecteur semi-transparent cylindro-parabolique est constitué par un réseau de fils (12) parallèles au plan de polarisation de l'onde émise par la source. Le réflecteur polariseur est formé d'une plaque réflectrice (14) située à λ/4 d'un réseau (15) de fils parallèles (16) inclinés à 45° par rapport au plan de polarisation de l'onde incidente.
Application aux antennes de surveillance et de désigna­ tion d'objectif.
