Abstract: In this paper we have developed a FDTD simulation
code which can treat wave propagation of a monopole antenna in a
metallic case which covers with PML, and performed a series of three
dimensional FDTD simulations of electromagnetic wave propagation
in this space .We also provide a measurement set up in antenna lab
and fortunately the simulations and measurements show good
agreement. According to simulation and measurement results, we
confirmed that the computer program which had been written in
FORTRAN, works correctly.
