摘　　要：随着车联网技术和车辆智能化的发展,车载天线正逐渐成为研究热点。天线作为收发信号的关键器件,对车辆智能化的实现起到了重要作用。研究重点集中在天线小型化、宽频带/多频点、高增益和多输入多输出技术等。车载天线在车辆的不同安装位置以及多变的外部环境的性能表现也有深入分析。本文首先论述了车联网的概念与背景以及车载天线性能指标,然后简述了三种常见的车载天线(鞭型天线、车窗玻璃天线和“鲨鱼鳍”天线)的演化过程,最后着重介绍了“鲨鱼鳍”天线与现阶段所提出的车载天线的研究状况,对车载天线的未来发展趋势进行了分析。With the development of intelligent Internet of Vehicles(IoV)technology,vehicle antennas are attracting attention in academics.As a key device for sending and receiving signals,the vehicle antenna plays a vital role in the realization of automotive intelligence.It mainly focuses on the miniaturization,broad/multi-band,high gain,and multi-input multi-out(MIMO)technologies.In-depth analysis is conducted on the vehicle antenna performance for different installation positions and the changing external environment.In this paper,it discusses the concept and background of the IoV and the performance requirements of vehicle antennas.It also briefly describes the evolution of three common vehicle antennas such as whip antenna,car window on-glass antenna,and"shark fin"antenna,and introduces the research progresses of the"shark fin"antenna and the recent vehicle antennas.Finally,the future trend of the vehicle antenna is analyzed.
