The data‐compressing technique, which has been broadly used in signal processing, is employed to efficiently predict the far‐field pattern in a finite‐difference time‐domain (FDTD) simulation. In this paper, we present a technique by which we compress the data of a surface‐field distribution on the surface of a Huygens' box and save it in a compressed file format that is much smaller than its original size. The far‐field pattern is predicted by using the reconstructed data in the time domain through the near‐to‐far‐field transformation module. A patch antenna is employed to validate the proposed scheme. © 2004 Wiley Periodicals, Inc.
