FIELD: antenna engineering.
SUBSTANCE: proposed antenna dome made in the form of hemispherical-top cylinder has equal wall thickness of 2 ± 0.2 mm and is manufactured by die casting method (without next varnish and paint coating) from polycarbonate wherein molybdenum disulfide is additionally introduced. Dome ablation rate is 0.0018 g/s and electromagnetic wave transit coefficient at frequency of 10 GHz is 83%.
EFFECT: enhanced erosion resistance of antenna dome.
