Millimeter wave radar antenna used for in-band radar applications, has wave guide element that is constructed and arranged to cooperate with edge-antenna, so that element is overlapped on upper side and opposite underside of antenna

摘要

The antenna (20) has a wave guide element (23) that is arranged between a primary radiator (22) and a lens (24), such that the cross sectional area of the wave guide element is formed at a the primary radiator whose facing side is smaller than the cross-sectional area of the wave guide element. The primary radiator is formed as edge-antenna. The wave guide element is constructed and arranged to cooperate with the edge-antenna, so that the wave guide element is overlapped on the upper side and the opposite underside of the edge antenna.
