PRODUCTION METHOD FOR A RADAR SENSOR

摘要

The invention relates to a method for producing a radar sensor (10) which is suitable particularly for producing highly integrated and nevertheless highly sensitive radar sensors. The radar sensor (10) has a plurality of antennas (18, 20) which can be driven differently and a distribution network (14) for driving the antennas (18, 20). The method according to the invention comprises the steps of: a) providing a ceramic support structure with the distribution network (14), in which support structure cavities are formed, b) filling the cavities with a material matrix comprising a first material with inclusions of a second material in order to form, within the material matrix, a large number of regions which have a lower dielectric constant than the first material, c) applying planar antenna patches to the material matrix.
