Patent attributes
A radar bracket for a vehicle includes a central portion configured to receive a radar module so that the radar module is exposed on a front side of the radar bracket, and a side wall encircling and extending laterally from the central portion and comprising a non-conductive material. At least of a portion of a backside of the side wall is covered by a radar absorbing material having a dielectric constant higher than a dielectric constant of the side wall. The at least a portion of the side wall has a thickness dw proportional to a quarter of the wavelength of a signal emitted by the radar module, and selected based on the dielectric constants of the side walls of the radar bracket and the radar absorbing material, such that a reflection at the interface between the side wall and the radar absorbing material is effectively cancelled out.
