FIELD: radio engineering, communication.SUBSTANCE: antenna dome comprises a ceramic cladding, a metal attachment ring, a dome-shaped radioparent heat shield and a heat-insulation ring. The shield is three-layered with external layers of heat-resistant fibre glass based on chromium aluminophosphate, polyimide, organosilicon or phenol-formaldehyde binder and an internal layer made of heat-resistant material based on glass or silica fibre. The external surface of the shield is coated with a heat-resistant coating. The heat-insulation ring is rigidly joined to the shield or is integrated with the shield and is made of material of the external layers of the shield, and is joined to the cladding and the attachment ring by a heat-resistant adhesive.EFFECT: reduced heat exposure of antenna devices of homing heads and low temperature of heating the attachment ring in non-steady aerodynamic heating conditions while providing improved radio characteristics in a wide frequency range.4 cl, 1 dwg |
