Patent attributes
An electromagnetic-wave-transmissive module of a vehicle radar is provided to minimize a dielectric impact reflection effect, which occurs when an electromagnetic wave radiated from an antenna is transmitted through a radome and a transmissive cover The electromagnetic-wave-transmissive module includes one or more of a radome covering the antenna and a transmissive cover, which is disposed to be spaced apart from a front side of the antenna and through which a radio wave radiated from the antenna and then transmitted through the radome is subsequently transmitted. At least one coating layer, which includes PTFE and which has a dielectric permittivity higher than the dielectric permittivity of air and lower than the dielectric permittivity of the radome and the transmissive cover, is formed on the surface of at least one of the radome and the transmissive cover.
