CA 2206443
A lens antenna is disclosed which comprises a conical horn and a lens attached to an aperture of the horn. The lens has a first planar surface at a first side which faces free space and a hyperboloid of revolution at a second side opposite the first side and is made of a dielectric material with relative permittivity ranging from 2 to 4. The lens is provided with a cylindrical portion which has asecond planar surface parallel to the first planar surface and displaced from the first planar surface by a predetermined distance. The cylindrical portion being concentric with the lens.
Antenne lentille comprenant un cornet conique et une lentille montée sur une ouverture du cornet. La lentille comporte une première surface planaire sur un premier côté donnant sur l'espace libre et une hyperboloïde de révolution sur le côté opposé au premier côté, et est composée d'un matériau diélectrique dont la permittivité relative est comprise entre 2 et 4. La lentille comprend une partie cylindrique ayant une seconde surface planaire qui est parallèle à la première surface planaire et séparée de celle-ci d'une distance prédéterminée. La portion cylindrique est concentrique par rapport à la lentille.
