ANTENNA HEAT-SHIELDING MULTILAYER INSERT Russian patent published in 2023 - IPC H01Q1/00 H01Q1/42 

FIELD: radio engineering.

SUBSTANCE: invention relates to radio engineering, in particular to composite materials for heat-shielding coatings and antenna radomes installed on aircraft. The effect is achieved by the fact that the antenna heat-shielding multilayer insert containing radio-transparent heat-shielding first and second layers, the first layer is made of a material that retains its structural integrity and electrodynamic parameters in a given range of high temperatures, and the second is made of a material with low thermal conductivity, is characterized in that the first layer is external, and the second layer is internal, while the first layer retains its structural integrity at a heating temperature up to 2000°C and is made in the form of a cylinder having parts of large, small and medium diameters.

EFFECT: expansion of the operating temperature range, preservation of the integrity of the outer surface of the antenna inserts, reliable fastening of materials to each other into a single antenna heat-shielding multilayer insert.
