| 摘要: |
| 与电调天线相较，机械天线具有全新的电气参数定义，其信号的频率只与携带辐射场的物质机械运动的频率相关，因而克服了电调天线信号频率对天线尺寸的依赖，可以用小型设备产生低频信号，应用于水下和地下便携式低频通信设备的设计中。从辐射场特性、辐射场发生装置以及信息加载三个方面介绍了机械天线通信系统的研究现状，总结了机械天线发展需要重点解决的技术难点。 |

| Abstract: |
| Compared with the electric tunable antenna,the mechanical antenna has a completely new definition of electrical parameters.The frequency of its signal is only related to the frequency of the mechanical motion of the material carrying the radiation field,thus overcoming the dependence of the signal frequency of the electric tunable antenna on the size of the antenna.This paper introduces the research status of mechanical antenna communication system from three aspects including the radiation field characteristics,the radiation field generating device and the information loading, and summarizes the technical difficulties that need to be solved in the development of mechanical antennas. |
| Key words: low frequency communication equipment mechanical antenna radiated field information loading |
