The European Union had set a target of reducing the car accident death rate by 50% from 2009 to 2010. This is why a few research teams came up with creative solutions revolving around the new embedded systems, such as adaptive cruise control radars or assistance sensors, that are becoming more and more mainstream within the car manufacturing industry.
This invention is in the field of radar antennas for collision detection in the road environment. The major problem raised by this invention was to design a compact antenna system, technologically mature, compatible with large series industrialization, and reconfigurable to satisfy several collision avoidance scenarios.
The main role of the pillbox coupler is to transform a cylindrical EM wave into a plane wave. Thanks to its straightforward implementation, the parabolic reflector is miniaturized and integrated in a dielectric substrate. This technology is compatible with PCB industrial processes.
