    摘要： A cylindrical focusing lens, including a dielectric radome (9, 49) and artificial dielectric material, in which the artificial dielectric material includes a plurality of sheets of a foam dielectric material disposed in layers and a plurality of short conductive tubes placed in the sheets of the foam dielectric material, in which the short conductive tubes disposed in the sheets of the foam dielectric material form a circle (5, 45) and a ring (8, 48) surrounding the circle (5, 45) and separated from the circle (5, 45) and from the radome (9, 49) by rings (10, 12, 50, 52) of the foam dielectric material without the short conductive tubes. The aforementioned lens overcome the deficiencies of the known lenses made of lightweight artificial dielectric material and is well matched with a free space. Additionally, the lens is simpler to manufacture than known analogous.
