1. An antenna apparatus comprising:
- a primary radiator for radiating a high-frequency radio wave beam;
a reflecting member for reflecting said radio wave beam;
an actuating mechanism for actuating said reflecting member; and
a lens for converging the radio wave beam reflected by said reflecting member to reduce an angle of divergence of the radio wave beam.

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.

11. An antenna apparatus comprising:
-
a primary radiator for radiating a high-frequency radio wave beam; a reflecting member for reflecting said radio wave beam; an actuating mechanism for actuating said reflecting member; and a main lens for converging the radio wave beam reflected by said reflecting member to reduce a diameter of the radio wave beam progressively along a direction in which the radio wave beam is propagated for thereby focusing the radio wave beam forwardly of the main lens. - View Dependent Claims (15, 16, 17, 18)
