摘　　要：汽车的智能化和网联化对车载天线的性能提出了更高的要求。传统测试方法仅仅是在微波暗室内检测天线单体的性能,并没有考虑天线装车后汽车周边电磁环境、车身结构、安装位置等因素,因此,并不能直观准确的反映整车级天线性能。文章利用仿真和整车OTA暗室等手段,对车载天线性能进行测试。研究发现,电磁环境、车身结构、安装位置等因素均对整车级天线性能有较大影响。此研究结果对车载天线设计和安装有一定指导意义。The intelligentization and network connection of automobile put forward higher requirements for the performance of vehicular antenna.The traditional test method which only tests the performance of the antenna unit in the microwave chamber ignores the influence of factors such as the electromagnetic environment around the vehicle,body structure,installation position,etc.,so it cannot reflect the full-vehicle level performance of antenna directly and accurately.In this paper,simulation and vehicle OTA chamber are used to explore the influence of the above factors on the performance of vehicular antenna.It is found that the electromagnetic environment,body structure and installation position have great influence on the full-vehicle level performance of antenna.The research results of this paper have certain guiding significance for the design and installation of vehiclar antenna.
