FIELD: physics.
SUBSTANCE: antenna dome has a radiotransparent coating made from porous ceramic, on the inner side of which there is a layer of ceramic with a polymer inside the pores, and on the outer surface there is a moisture-resistant coating deposited on a porous coating which is first blocked with acetone, wherein the on the surface of the coating there are annular trapezoidal cavities with depth of 0.003-0.010 times the operating wavelength of the antenna. On the acetone-blocked surface there are also annular belts made from material whose permittivity is greater than that of the coating material, wherein thickness of the annular belts ranges from 5 to 300 mcm.
EFFECT: improved radio characteristics of the antenna dome.
