摘要
根据地铁通信的要求,需要在地铁车顶上安装体积小、轮廓低的全向天线。首先详细地介绍了单极天线的特性,研究了如何降低天线高度和增加使用带宽的技术方法,全面地讨论了倒F天线的设计方法和主要参数;然后对倒F天线的结构和电性能进行了仿真分析;最后制作出了一种性能较好的倒F天线,通过实际测试,验证了仿真结果。该形式全向天线在地铁通信中已经得到广泛应用。
For the subway communication, it is necessary to install the omni-directional antennas with small size and low profile on the train roof. This paper introduces in detail the characteristics of monopole antenna, studies the technical methods for reducing the antenna height and increasing use of bandwidth, and discusses comprehensively the inverted F antenna design methods and the main parameters. Then the simulation analysis is made about the inverted F antenna structure and electrical performance. Finally an inverted F antenna with better performance is made, and the simulation result is verified through the actual test. The form of omni-directional antenna has been widely used in the subway communication.
