W-band antenna-reflector combined in a lens

Automotive radars are becoming widespread for safety reasons. However their effectiveness remains doubtful since even a metal car does not have strong RCS over all angles of its body. For reduction of traffic accidents, the solution is not only surveying around car-body but also making vehicles easi...

Description
Summary:Automotive radars are becoming widespread for safety reasons. However their effectiveness remains doubtful since even a metal car does not have strong RCS over all angles of its body. For reduction of traffic accidents, the solution is not only surveying around car-body but also making vehicles easily visible to drivers by means of radar and other luminous sources. This paper introduces a lens antenna double as a reflector for radio and light waves as vehicle equipment.
