Disclosed are an antireflective lens for infrared rays that eliminates wavelengths in an infrared region to thus improve an antireflective effect and a method of manufacturing the same. The antireflective lens for infrared rays may be an antireflective lens used in an infrared band. The antireflective lens includes a lens base part including a base refractive material having a refractive index of about 3.0 or greater and an antireflective coating part formed on a front surface of the lens base part.

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.

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 is a radio-wave-transmissive cover of a vehicle radar, which exhibits a metallic color and is imparted with improved radio-wave transmission performance. The radio-wave-transmissive cover may include an optical film formed by simultaneously depositing an aluminum (Al) material and a low-melting-point material, such that a radio wave radiated from an antenna of a radar, for example, provided in a vehicle is transmitted. The radio-wave-transmissive cover includes a substrate, and an optical film including aluminum (Al) and a low-melting-point metal having a melting point less than the melting point of aluminum (Al) on the surface of the substrate.
