从空间覆盖的角度来看，天线的安装位置对于包括自动驾驶在内的各种应用都很重要。汽车的车顶是常见的天线安装位置，但即使如此，对于天线在车顶孔上的安装位置也不存在固定或明确的规则。天线通常设计为在自由空间条件下工作，车身上的安装位置可以改变天线的性能。本文研究了天线的安装位置对其辐射方向图的影响。在车顶上选择几个安装位置进行测量。结果表明，天线的合适安装位置随工作频率的变化而变化。可以看出，对于较低的频率，前面和后面的位置适合安装天线，而对于较高的频率，汽车的侧面表现出更好的性能。
Mounting location of the antenna is important from the point of view of spatial coverage for a variety of applications including automated driving. The roof of the car is a common antenna mounting location, but even then there exists no fixed or explicit rules for mounting location of the antenna on the car roof aperture. Antennas are usually designed to operate under free-space conditions and the mounting location on the car body can alter the performance of the antenna. This paper investigates the effect of the mounting position of the antenna on its radiation pattern over a wide frequency range. Several mounting positions on a car roof top were selected to perform the measurements. It is shown that suitable mounting position of the antenna changes with the operational frequency. It is seen that for the lower frequencies, the front and back positions are suitable to mount the antennas, while for the higher frequencies, the side of the car shows a better performance.
