Abstract：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.
