Automotive polarimetric radar sensor with a circular polarization (CP) MIMO antenna configuration with a single CP TX antenna and dual CP RX antennas.

77 GHz

Gap waveguide design for extremely low loss, efficient integration with the RF circuit board and lower overall manufacturing cost. Antenna design that employs series-fed septum polarizers for a low-profile.

Advanced automotive radar front ends.

40 m range was demonstrated for targets in motion at velocities up to 40 km/h in the radial direction.
