Fundamentals of Antennas and Antenna Arrays

Abstract In many modern radar applications in the millimeter wave range, the radar must determine not only the range and velocity of a target, but also its angle at which it is located in relation to the radar. For this purpose, antenna arrays are required, i.e. a group of antennas.
