Antenna Technology forMillimeter WaveAutomotive Sensors

Automotive sensorsforthedetection and discrimination ofother vehicles ontheroad, obstacles, andboundaries useminiature radarsystems andare heavily dependent intheir performance ontheantenna system. Inthis contribution, therequirements forsuch antenna systems arereviewed andthevariousoptions ofantennatechnology are discussed. Inparticular, prominent and presently employed, as wellas innovative antennaconcepts forforwardlooking obstacle avoidance andautonomous cruisecontrol are presented. Inconclusion, antennarequirements are discussed inthelight ofkeyrequirements ofadvanced future automobile sensorsystems.
