Numerical simulation of antennas using three-dimensional finite-difference time-domain method

The paper presents numerical simulations of various antennas using the three dimensional finite difference time domain (FDTD) method. The FDTD code uses the perfectly matched layer absorbing boundary condition (PML-ABC) and a time domain near to far field transformation function. The method is shown to be an efficient tool for modeling complicated antenna structures. The calculation results are compared with the measured data and shown to be in good agreement.
