Research on the radiation characteristics for the seawater antenna

A large number of antennas lead to the ship crowded. In this paper, on the basis of the seawater can be used as an antenna, analyzed the superiority of the seawater as the antenna in theory. Through numerical methods calculating, researched the changing of the radius and height of the water column to it radiation characteristics, Compared the difference between the seawater antenna and conventional metal antenna in the direction of the electric field view. At last, the article look to the application prospects of the seawater antenna.
