Abstract :
In this paper, the application of the discrete Green´s function (DGF) method in the monopole antenna modeling with finite and infinite ground plane is presented. In the infinite ground plane case, the current distribution of antenna is obtained using image theory. While, in the finite ground plane case, the infinite free space DGF is used to obtain the current distribution on the antenna and ground plane. It is shown that the finite ground plane affects the properties of antenna, particularly the radiation pattern.
