An eight channel planar dual reflector antenna to be used in a 77 GHz automotive radar sensor is presented. To meet the requirements of a combined medium and long range sensor, the antenna beams are shaped by use of dielectric radiators as feeds. These feed elements are designed to broaden particular beams either only in the azimuthal plane or in both planes. The characteristics of the feed elements were simulated using the Finite Integration in Time domain method (CST Microwave Studio). To predict the radiation pattern of the dual reflector antenna, the FIT simulation results served as input for a ray tracing based mathematical antenna model.
