The project "MilliScan - realization of a highly integrated 3D radar system at 240 GHz“, funded by the German Research Foundation (DFG), investigates novel frequency-agile antenna arrays and transceiver architectures as parts of a high resolution 3D imaging radar with fully electronic beam-steering (1D by Butler matrix, 1D by holographic antenna, 1D by FMCW) for indoor tracking or collision protection for autonomous vehicles. Optimization of millimeter-wave monolithic integrated circuits (MMIC) and antenna integration in a package represents a particular challenge. An MMIC-based on-chip broadband Butler matrix at 240 GHz for 4-channel electronic beam-steering, integrated with active switches and amplifier stages, will be developed by the group at ILH, which teams up with the Karlsruhe Institute if Technology (KIT) in this collaborative project.
