Directly applying the higher‐order FDTD method to the computation of antenna patterns has not been a practical approach thus far. One of the main difficulties is how to handle the perfect electric conductor (PEC), which is always present. This paper describes a procedure for handling the PEC using the S 24 FDTD method, which is capable of directly computing the antenna far‐field patterns. Accuracy of the algorithm is demonstrated by comparing the antenna patterns with those calculated from the near‐to‐far field transformation and cavity model. © 2004 Wiley Periodicals, Inc.
