In this paper, the authors designed and interpreted the array antennas of the aperture-coupled microstrip operating in the millimeter-wave band for radar system. The microstrip array antenna can be designed with a transmission line circuit and a matching circuit in the same substrate. Therefore, it is easy to combine with the active elements of the system. They add the slots to the patch to overcome it because general microstrip patch antennas have narrow band characteristics. They have designed the U-shaped slots in the patch.
