Abstract
An antenna apparatus for use as in an automobile collision warning system has a primary radiator for radiating a high-frequency radio wave beam, a reflecting member for reflecting the radio wave beam, an actuating mechanism for actuating the reflecting member, and a lens such as a dielectric lens for converging the radio wave beam reflected by the reflecting member to reduce an angle of divergence of the radio wave beam.
