Industrial Antenna Development for 77-GHz Level-Crossing Monitoring Radar [Antenna Applications Corner]

Preventing accidents at level crossings is a global-size problem. Despite all the European railways having planned to replace them with underpasses or overpasses, it is expected that, for the next 20 years, there will still be a strong need for additional automatic protection to be achieved with, for example, a radar detection system. In this article, we present and compare the different antenna solutions that have been designed and manufactured...
