When the electromagnetic wave propagates in water, the attenuation will increase with the increase of frequency, so the application of electromagnetic wave in water is limited to the low frequency band. At present, in order to realize the low-frequency electromagnetic wave radiation, the commonly used method is tuning the spiral tube coil antenna (Electromagnetic radiator). In practical application, the electromagnetic radiator used to realize high-power electromagnetic radiation usually has the characteristics of large size and many coil turns. Therefore, for the development of high-power electromagnetic radiator, there are many difficulties, such as high cost and difficult manufacture. Therefore, it is necessary to analyse the relationship between the radiation performances of different sizes of electromagnetic radiator, and use this relationship to guide the development of high-power electromagnetic radiator. Based on this, this paper analysed the radiation characteristics of spiral tube coil antenna, and the application of small-size electromagnetic radiator in the development of electromagnetic radiator.
