【摘要】：微带天线因为其工艺简单、价格低廉、易于集成、一致性好的特点,已经应用到越来越多的天线工程领域。本文主要研究了面向车载应用的微带天线,在车载防撞雷达阵列天线、平面贴片透镜天线、车载GSM/3G电子等方面进行了研究,并且进行了相应的加工测试,取得了较好的结果,在一定程度上提高了前人的研究成果。 在车载防撞雷达微带阵列天线的研究上,本文利用阵列理论对所设计的天线进行优化布局和激励综合,实现了波瓣的赋形和优化。仿真设计并加工测试了一款4*14的24G车载防撞微带阵列天线,实现了100°的波束扫描。 同时,本文还对平面贴片透镜天线进行了研究,该天线运用微带技术所设计,采用一种单元结构在｜S21｜≥-2dB的情况下实现了0°-360°的相位响应,馈源在焦点的单波束能够实现20.61dB增益和41.8%口径效率的测试结果。利用馈源的偏焦技术,设计了一款264个单元组成的多波束平面贴片透镜天线,实现仿真最高增益23.72dB,后瓣低于主瓣16.26dB,最高旁瓣6.67dB,3dB波瓣宽度为7.3°(E面)和10.78°(H面)。 最后本文还对一款工作在824-960MHz/1710-2170MHz的车载微带天线进行了设计研究,实现在仿真及测试上在所需频率范围内VSWR2的全向天线。
[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 掳. 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 掳-360 掳is realized by using a unit structure with S21 鈮，
