Abstract

In order to reduce the cost and blindness of antenna design, the application of electromagnetic field similarity principle in the working environment of underwater receiving antenna was studied and verified. The field distribution and electrical parameters of the underwater receiving antenna and its reduced-scale model were calculated and proved to be in accordance with the similarity principle. The simulation analysis of the receiving antenna and its reduced-scale model for receiving the airborne electromagnetic wave signal in the seawater shows that the underwater receiving antennas before and after the scale-down are similar. The simulation is verified by measuring the receiving signal amplitude of the underwater receiving antenna and its reduced-scale model. The results of theoretical derivation and simulation analysis show that the electromagnetic field similarity principle can be applied to the underwater receiving antenna system.
