Phased Array Antenna of Millimeter Range for Automotive Radar

Abstract

One of the most important tasks presently is to improve road safety. Driver assistance systems allows easier and safer to drive a vehicle. Often these systems are built on radar. One of the main components of the radar is a phased antenna array. The process of building a phased antenna array for a automotive radar is described in this paper. The approaches to the choice of the model and structure of the radiation element of the array are considered. Also the question of the correct choice of the method of feeding of the array elements is discussed. The results of modeling the phased antenna array are presented.
