FIELD: radio engineering, communication.
SUBSTANCE: ultra-wideband radar-absorbent coating is in the form of a multi-layer metal-polymer-matrix composite material, whose layers have different thickness: a first layer consisting of flake-like particles with size of 5-25 mcm with thickness of 2.0-3.0 mm, a second layer of flake-like particles with size of 3-10 mcm with thickness of 1.0-1.5 mm, a third layer of spheroidal particles with size of 1-5 mcm with thickness of 0.5-1.0 mm, a fourth layer of spheroidal particles with size of 1-5 mcm with thickness of 1.0-2.0 mm, a fifth layer of spheroidal particles with size of 1-5 mcm with thickness of 3.0-3.5 mm.
EFFECT: reducing the unevenness of beam patterns of ultra-wideband helical antennae mounted on a metal platform to a level of 1 dB, ensuring operating capacity of a system of ultra-wideband helical antennae within specification requirements.
