ABSTRACT:
A millimeter-wave radar has a radome or radar cover including a layer, the dielectric constant of which is a greater than that of the other portion without the layer, or including a magnetic loss layer in an appropriate position with respect to the antenna. The dielectric constant of the radome or radar cover 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.
