Abstract
Provided are a structure and alignment method of array antennas for a vehicle radar, the structure and method being able to adjust the locations, number of channels, number of arrays, and channel distance according to the type of antennas, so as to minimize a space occupied by the antennas while maintaining the radiation efficiency of the antennas. Even in a case in which conditions regarding the location of the array antennas and the number of channels are changed within designated ranges, the efficient array antenna structure minimizes the area of array antennas for a vehicle while maintaining the detection ability of the array antennas.
