In this paper, microstrip patch arrays with both uniform phase and tapered distributions are analyzed via the finite‐difference time‐domain (FDTD) technique. The phase delay in the frequency domain is converted into a delay in the time domain when exciting the array. The far field pattern of the array is calculated from its aperture distribution, in a plane located just above the array. A PMC plane has been employed to reduce the problem to half its size by invoking the symmetry of the problem. The results are found to be in good agreement with those derived by using the method of moments (MoM). © 2003 Wiley Periodicals, Inc.
