电磁波频率和天线深度对水下环天线的影响

内容简介：海水中的环天线是进行水下电磁通信的主要手段,研究其在空气中产生的场具有重要的实际意义.针对这个问题,建立了3层导电媒质(空气、海水、大地)条件下海水中环天线的辐射模型,得到了空气中电磁场的解析表达式.采用控制变量法,仿真分析了电磁波传播频率和发射天线深度对水下环天线在空气中产生的场的影响,为水下电磁通信的实际应用提供了依据.

Abstract：The loop antenna in sea is the major measures in radio communication, so it is practically important to study the fields in the air generated by the loop antenna. Aiming at this problem, a radiated model for the underwater loop antenna in three layers of conductive media (air, sea, and earth) was established, and the analytical expressions of the electromagnetic fields in the air were obtained. The influence of the propagation frequency and antenna depth on the fields was emulated and analyzed by controlling variable, which provided a basis for the application of the underwater electromagnetic communication.
