Antenna device for radar sensor, method of manufacturing antenna device for radar sensor, and use of antenna device in radar sensor

摘要

An antenna device (100) for a radar sensor (200) comprising:-having a defined number of flat antenna members (10) wired in series; At least one first antenna array (20) arranged on the surface of the substrate (1); on a substrate (1) having a defined number of flat antenna members (10) wired in series At least one second antenna array (30) arranged in two;-both antenna arrays (20, 30) and the supply conductor (12) respectively wired at the center; the supply conductor (12) by means of the supply conductor (12) (20, 30), whereby the first antenna array (20) can be supplied with a supply signal which is phase-shifted by 180 degrees compared to the second antenna array (30) It has become the jar.
