Antenna Technology for Millimeter Wave Automotive Sensors

Automotive sensors for the detection and discrimination of other vehicles on the road, obstacles, and boundaries use miniature radar systems and are heavily dependent in their performance on the antenna system. In this contribution, the requirements for such antenna systems are reviewed and the various options of antenna technology are discussed. In particular, prominent and presently employed, as well as innovative antenna concepts for forward looking obstacle avoidance and autonomous cruise control are presented. In conclusion, antenna requirements are discussed in the light of key requirements of advanced future automobile sensor systems.
