Abstract
A dielectric lens device for shaping a radar beam includes a first and a second plano-convex cylindrical dielectric lens member and a plane-parallel dielectric substrate. The two plano-convex cylindrical dielectric lens members are arranged with their plane surfaces towards a same surface of the plane-parallel dielectric substrate. The plano-convex cylindrical dielectric lens members are interconnected to the plane-parallel dielectric substrate in a material fit.

A radar device for interior automotive radar sensing applications, comprising:
- a dielectric lens device for shaping a radar beam, comprising:
- a first plano-convex cylindrical dielectric lens member and a second plano-convex cylindrical dielectric lens member,
- a plane-parallel dielectric substrate,
- wherein
- the two plano-convex cylindrical dielectric lens members are arranged with their plane surfaces towards a same surface of the plane-parallel dielectric substrate, and
- the plano-convex cylindrical dielectric lens members are interconnected to the plane-parallel dielectric substrate in a material fit, and
- at least one radar antenna member,
- wherein
- the at least one radar antenna member is arranged in a spaced manner to face a surface of the plane-parallel dielectric substrate opposite of the two plano-convex cylindrical dielectric lens members, and
- the at least one radar antenna member is arranged such that a direction of its strongest power emission runs perpendicular to the surface of the plane-parallel dielectric substrate.
