Abstract

L'invention concerne une antenne à haute fréquence comportant une lentille attaquée par plusieurs bornes d'attaque. La lentille comporte une région à plaques parallèles en circuits, imprimés et une section de polariseur. Cette dernière est constituée par des couches polarisantes séparées par des couches de matière diélectrique; les constantes diélectriques sont choisies de manière à former des faisceaux collimatés associés chacun avec l'une des bornes d'attaque. L'invention s'applique notamment à des antennes fonctionnant avec des ondes radio-électriques de polarisation arbitraire.
