Abstract
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 a second 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.
