The finite difference time-domain(FDTD) method is one of the most widely used computational methods in electromagnetics. The basic FDTD approach of solving Maxwell's equations directly in the time domain via finite difference and time stepping has been reviewed. An FDTD algorithm programmed with the Matlab, a very inviting property of which is the wide varity of two- and three-dimensional visualization tools, simulates electromagnetic pulse as it radiates from the typical antennas such as dipole antenna, folded dipole antenna and Yagi-Uda antenna. A visualized time domain simulations of conventional well known antennas provide a much intuitive view of field radiation.
