DIELECTRIC POLYMERIC FOAM AND ITS UTILIZATION IN PRODUCTION OF LENSES FOR RADIO WAVES Russian patent published in 2005 - IPC

Abstract RU 2263124 C2

FIELD: usage of the dielectric polymeric foam as different dielectric materials in production of lenses for radio waves.

SUBSTANCE: the invention is pertaining to a dielectric polymeric foam and its utilization in production of lenses for radio waves. The dielectric polymeric foam is intended for utilization in the capacity of different dielectric materials, including as the material for production of spherical lenses for radio waves and Luneberg lens. The polymeric foam has a dielectric permeability of no less than 1.5 at 12 GHz and 25 °C and is produced by a foaming of the polymeric composition, which contains a synthetic polymetric compound and one or more dielectric inorganic filler. The filler is selected from a fibrous titanate of the alkaline-earth metal and a lamellar titanate of the alkaline-earth metal. The produced dielectric polymeric foam has good and uniform dielectric features.

EFFECT: the invention ensures production of the dielectric polymeric foam with good and uniform dielectric features.
