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.

Electromagnetic-wave-transmissive module of vehicle radar

The present disclosure relates to a composition for a radar transmissive cover for a vehicle, which may enhance dielectric properties while excellently maintaining mechanical properties. The composition, as the composition forming the radar transmissive cover for the vehicle through which a radar beam radiated from a radar is transmitted, has a main material in which 70 to 90 wt % of Polybutylene Terephthalate (PBT) and 10 to 30 wt % of Polycarbonate (PC) are mixed and an additive containing at least reinforcing filler mixed.

Composition for radar transmissive cover for vehicle

Disclosed are an electromagnetic-wave transmitting cover that transmits electromagnetic waves transmitted/received by an LF antenna and an RF antenna and an electric field generated from a capacitance touch sensor while realizing a metallic texture, and a door outer handle including the same. The electromagnetic-wave transmitting cover includes: a substrate; a primer layer formed on a surface of the substrate; and a first metal layer formed by depositing and having a plurality of first microcracks penetrating in a thickness direction.
