Abstract
A radar detector adapted to be carried by a motor vehicle, includes a housing enclosing a compact horn antenna having a tapering wall portion which defines a cavity extending from an aligned aperture within the housing. A plano-convex dielectric lens extends across the aperture and cavity and introduces a microwave phase delay decreasing from the center of the cavity towards the tapered wall portion of the horn antenna to compensate for the deficiencies in the compromised design of the antenna and for significantly increasing the sensitivity and gain of the detector. The dielectric lens may project outwardly from the housing or inwardly into the antenna cavity and may be molded as an integral part of the front wall of the detector housing. In one embodiment, the lens is also adapted to be conveniently attached to an existing radar detector.
