METAL COATING FOR ELECTROMAGNETIC WAVE TRANSMISSION, METHOD FOR PRODUCING METAL COATING FOR ELECTROMAGNETIC WAVE TRANSMISSION, AND RADOME FOR VEHICLE RADAR DEVICE

摘要

The present invention addresses the problem of providing: a metal coating for electromagnetic wave transmission, the metal coating being highly mass-producible and having an extremely low transmission attenuation rate for electromagnetic waves; a method for producing the metal coating for electromagnetic wave transmission; and a radome for a vehicle radar device using the metal coating. In order to solve this problem, provided is a metal coating for electromagnetic wave transmission comprising greater than 10,000 fine metal regions per unit area (1 mm2), the fine metal regions being provided to the surface of a base material through a non-electrolytic plating step, wherein the metal coating is characterized in that mutually adjacent fine metal regions are electrically isolated; also provided are a method for producing the metal coating for electromagnetic wave transmission, and a radome for a vehicle radar device using the metal coating.
