Millimeter wave-radar and method for manufacturing the same

摘要

The invention relates to a millimeter-wave radar having a radome (2) or radar cover (7) including layer (10), the dielectric constant of which is greater than that of the other portion without the layer (10), or including a magnetic loss layer (11) in an appropriate position with respect to the antenna. The dielectric constant of the radome (2) or radar cover (7) can be made higher in a portion corresponding to the side of the antenna than in a portion corresponding to the front of the antenna.
