            Abstract : 
The effect of finite size of the ground plane on the impedance of a monopole immersed in a lossy medium is studied. The theoretical results show that for water medium and for the ratio of the ground-plane radius to free-space wavelength equal to and greater than 0.2, the effect of ground plane on the monopole impedance is negligible.
