[Abstract]:Microstrip antenna has been applied to more and more antenna engineering fields because of its simple process, low cost, easy integration and good consistency. In this paper, the antenna array of vehicle-mounted anti-collision radar, the plane patch lens antenna, the on-board GSM/3G electronics and so on are studied, and the corresponding processing tests are carried out. Good results are obtained and the previous research results are improved to a certain extent. On the research of the microstrip array antenna of vehicle-mounted anti-collision radar, the array theory is used to optimize the layout and incentive synthesis of the designed antenna. The configuration and optimization of the lobes are realized. A 24G anti-collision microstrip array antenna is designed and tested by simulation, and the beam scanning is realized at 100 擄. At the same time, the planar patch lens antenna is studied in this paper. The antenna is designed by using microstrip technology, and the phase response of 0 擄-360 擄is realized by using a unit structure with S21 鈮，
