Abstract:
An eight channel planar dual reflector antenna to be
used in a 77GHz 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.
