Abstract

L'invention concerne une lentille diélectrique destinée à convertir un front d'onde sphérique de rayonnement électromagnétique en un front d'onde plan La lentille est réalisée en matière plastique expansée uniformément, avec une constante diélectrique de l'ordre de 1,05 à 1,5. Un revêtement absorbant le rayonnement est disposé sur une surface de la lentille afin d'éviter toute réflexion du rayonnement. L'invention s'applique notamment au contrôle de portée des antennes.
