Abstract In this paper, Finite Difference Time Domain(FDTD) method is used to calculate the radiation characteristics of the antenna located on loss ground. For FDTD method, there are different feed models to calculate the input impendence of antenna. The results calculated by different feed models are compared with each other. The important point of the paper is to calculate the radiation characteristics of monopole on dielectric plane, and analyzes input impedance change with the size change of conducting ground system on the surface of dielectric plane.
