摘要:
A luneberg lens, which is configured by combining a plurality of lens parts, has a problem on keeping of a combined condition of lens parts and securement of good moisture prevention, and displacement of lens parts not only becomes a cause of cost-up but also has a bad influence on an electric performance, and furthermore, intrusion of moisture and humidity deteriorates an electric performance, and therefore, these problems are solved by a simple and inexpensive method. A lens portion 2, which is configured by combining lens parts of spherical core and spherical shell-like resin foams, is configured by a luneberg lens which is sealed by a synthetic resin film 3 which is formed along a surface of that lens portion 2 and in which a thickness is 100 μm or less and of which own relative dielectric constant is higher than a relative dielectric constant of the outermost layer of the above-mentioned lens portion.

A hemispherical Luneberg dielectric lens including a hemispherical center layer having a hemispherical outer surface, and a plurality of hemispherical dome-shaped layers each having concentric hemispherical inner and outer surfaces, the outer surfaces of the center layer and dome-shaped layers having different diameters and the inner surfaces of said dome-shaped layers having different diameters. The center layer and dome-shaped layers are successively concentrically fitted into one another and integrated into a hemispherical shape. The center layer is a foam molding of ceramic-containing thermoplastic resin expanded beads, while each of said dome-shaped layers is a foam molding of thermoplastic resin expanded beads containing 0 to 80% by weight of a ceramic. The ceramic content per unit volume of the center and dome-shaped layers decreases from the center layer to the outermost dome-shaped layer, and the standard deviation of the apparent density of each of the center and dome-shaped layers is 0.07 g/cm3 or lower.

摘要:
In a radio wave lens antenna, a lens cover for covering the surface of the lens is stably fixed to the reflector. The antenna has a semispherical Luneberg lens, a semispherical shell-shaped lens cover for covering the surface of the lens, a radio wave reflector, a ring-shaped plate placed along the outer circumference of the lens, a primary feed placed at the focal point of the lens, and a holding part for the primary feed. A flange provided at the opening edge of the lens cover is clamped by the reflector and the plate to fix the lens cover to the reflector, and more preferably, the lens cover is caused to be in contact with the lens, and the lens is pressed also in the radial direction by the plate via the lens cover.

A radio wave lens antenna device including a semispherical Luneburg lens and a radio wave reflection plate. The radio wave lens antenna device prevents the signal reception sensitivity from being lowered in rain or snow. The radio wave lens antenna device includes a semispherical Luneburg lens 1, a radio wave reflection plate 2 that is larger than the diameter of the lens, an antenna element 3, and a holder 4 that holds the antenna element. The radio wave reflection plate 2 is arranged in an erected state. An ice-snow-water resistant means, which includes a first cover 5 and a second cover 6, prevents rain, snow, and ice from collecting and running off the Luneburg lens.
