DEVICE WITH LOW COEFFICIENT OF REFLECTION OF RADIO WAVES IN WIDE FREQUENCY RANGE Russian patent published in 2016 - IPC H01Q1/42 

FIELD: radio engineering.

SUBSTANCE: invention relates to radio engineering and concerns developing structures with low coefficient of reflection of radio waves for protection of motorboats against action of incident radiation and external factors of environment. Device with low coefficient of reflection of radio waves in a wide frequency range according to invention consists of input outer layer facing towards incident radiation, and output outer layer, input outer layer is made from material with relative dielectric permeability of 3 to 5 and thickness of 4 mm to 40 mm, and output outer layer is made from electrically conducting material with thickness of not more than 1 mm with surface electric resistance from 250 to 400 Ohm.

EFFECT: proposed device with low coefficient of reflection of radio waves will allow to reduce a radar visibility of object in comparison with metal surface up to 10 times, and compared with single-fibre glass with thickness of 4 mm to 40 mm - up to 3 times.
