AUTOMOTIVE MICROWAVE LENS DEVICE FOR GENERATION OF HEART-SHAPED RADIATION PATTERN IN INTERIOR CAR SENSING APPLICATIONS

摘要

A dielectric lens device (14; 40) for shaping a radar beam comprises a first (16; 42) and a second plano-convex cylindrical dielectric lens member (20; 52), and a plane-parallel dielectric substrate (24). The two plano-convex cylindrical dielectric lens members (16, 20; 42, 52) are arranged with their plane surfaces towards a same surface of the plane-parallel dielectric substrate (24). The plano-convex cylindrical dielectric lens members (16, 20; 42, 52) are interconnected to the plane-parallel dielectric substrate (24) in a material fit.
