122 GHz radar sensor based on a monostatic SiGe-BiCMOS IC with an on-chip antenna

In this paper, a short range monostatic radar sensor operating at 122 GHz is presented. The millimeter-wave frontend, including the on-chip antenna, is based on an integrated circuit realized in SiGe BiCMOS technology. The setup of the radar sensor is introduced and measurement results for FMCW modulation demonstrate the performance of the radar frontend.
