For driver's convenience, the ACC (Adaptive Cruise Control) requires a system which controls the vehicle to keep the distance among the automobiles constant. This paper describes the microstrip array antennas designed to operate at 24 GHz, and used as a direction indicator of moving vehicles. $8{\times}2$ transmit away antenna with wide beamwidth, $8{\times}4$ receive center array antenna, and two $8{\times}8$ receive array antennas with narrow beamwidth were designed. The measured result shows that the designed array antennas arc suitable fur detecting 3 directions of the vehicle when the scan angle is within the restricted area.
