Abstract

Antenne permettant de réaliser un réseau de faisceaux hertziens à forte densité. Pour éviter les effets de masque et pour que le niveau des lobes secondaires soit faible, l'antenne est réalisée à l'aide d'une lentille à diélectrique isotrope 1, d'un réflecteur plan 3 et d'un cornet 2. Le cornet qui est décalé par rapport à l'axe XX de la lentille, rayonne une onde sphérique. Le réflecteur donne du cornet une image située au foyer F de la lentille. Ainsi, après avoir traversé la lentille, l'onde sphérique émise par le cornet est transformée en une onde plane. Application aux faisceaux hertziens.
