Participation at EU-funded project: MID4Automotive

The project goal is to develop low-cost, high-performance and highly integrated radar systems that can be directly integrated into plastic surfaces. This will be based upon 3D-MID (Molded Interconnect Device) technology. Radar transceivers integrated in this way will be connected directly to the antennas in order to minimize losses due to reflection, attenuation and phase shift.
