摘　　要：使用电磁波进行水下通信具有传播速率高等优势,文章针对电磁波水下通信中环天线的设计,在对电磁波传播特性进行研究的基础上,分析了传播速度和波长对环天线的影响,推导出了水下环天线的辐射功率和辐射阻抗的解析表达式,仿真分析了水下环天线的辐射特性,得出了天线尺寸和工作频率对辐射特性的影响,为环天线的设计和应用提供了参考。Underwater communication using the electromagnetic wave has the advantage of high propagation rate and so on.Aiming at the design of the loop antenna in the underwater communication of the electromagnetic wave,based on the research of the propagation properties of the electromagnetic wave,this paper analyses the influence of the propagation rate and the wave length on the loop antenna,derives the analytic expression of the radiated power and the radiated impedance of underwater loop antenna,emulates and analyses the radiated properties of the underwater loop antenna and obtains the influence of the size and the working frequency of the antenna on the radiated properties,which provides a reference to the design and application of the loop antenna.
