Abstract

The invention relates to a housing (1) with radar-absorbent properties, in particular for a radar sensor in a motor vehicle, with electrically conductive particles whose dimensions are adapted to the frequency of the radar beams to be absorbed. The housing (1) comprises a material that as its basic component contains plastic, either unreinforced or reinforced with glass fibers, selectively mineral-filled, and contains as an additive steel fibers (2) in a mixture such that the specific conductivity .sigma. of the housing adheres to a predetermined value.
