Abstract: A device to conceal a radar or any other system for the transmission and reception of electromagnetic waves represents, for example, a pattern in relief. The device comprises at least one front part transparent to electromagnetic and optical waves, one rear part transparent to electromagnetic waves facing transmission and/or reception means and a form representing the manufacturer's logo placed between the parts. This form has an cellular structure with RF characteristics close to those of air. That device can be applied especially in radars equipping vehicles.

Abstract: Disclosed is a device to conceal a radar fitted for example into a vehicle. This device bears especially a pattern. A method to make such a device is also disclosed. The device reproduces a given pattern comprising a shiny part. It comprises at least one front part transparent to optic waves and one part having a face with a shiny appearance before the rear face of the front part. The non-shiny part of the pattern covers the rear face of the front part. The invention can be applied especially to radars positioned on the front of vehicles.
