基于十种商用车辆的整车球面近场测量数据，分析车载天线安装影响，并提出用少量物理参数生成真实方向图的统计模型，为车载通信仿真提供基础。
AI 中文摘要
车载天线在安装后，由于与车身的相互作用，其辐射方向图可能发生显著改变。然而，现有研究主要集中于仿真或孤立的天线表征，大规模实验研究仍然有限。本文基于整车球面近场测量，对车载天线辐射方向图进行了全面的实验分析。在统一的测量框架下，建立了一个覆盖十种商用车辆平台、多种天线安装位置以及包括4G、5G、V2X和GNSS在内的多种无线功能的大规模数据集。基于测量结果，进行了代表性案例研究和统计表征，以探究车辆安装对天线辐射行为的影响。结果揭示了不同安装位置和无线功能之间的显著差异，突出了车辆集成对实际天线性能的强烈影响。此外，提出了一种新颖的统计模型，利用少量物理可解释的参数生成真实的车载天线方向图。所获得的数据集、表征结果和建模方法为车载通信应用中的真实天线评估和无线系统仿真提供了基础。
英文摘要
Vehicle-mounted antenna radiation patterns can be significantly altered after installation due to interactions with the vehicle body. However, existing studies mainly focus on simulations or isolated antenna characterization, while large-scale experimental investigations remain limited. This paper presents a comprehensive experimental analysis of vehicle-mounted antenna radiation patterns based on full-vehicle spherical near-field measurements. A large-scale dataset covering ten commercial vehicle platforms, multiple antenna mounting locations, and various wireless functions, including 4G, 5G, V2X, and GNSS, is established under a unified measurement framework. Based on the measured results, representative case studies and statistical characterization are performed to investigate the impacts of vehicle installation on antenna radiation behavior. The results reveal substantial variations across mounting locations and wireless functions, highlighting the strong influence of vehicle integration on realistic antenna performance. Furthermore, a novel statistical model is proposed to generate realistic vehicle-mounted antenna patterns using a small set of physically interpretable parameters. The obtained dataset, characterization results, and modeling approach provide a foundation for realistic antenna evaluation and wireless system simulations in vehicular communication applications.
