This paper presents a technique to compress the near‐field data required to compute the radiated fields using FDTD. This technique is applied to the study of a UWB planar diamond antenna. The results show a 99.8% gain in memory storage, while maintaining good accuracy: less than 1% error on the far‐field radiation patterns. © 2006 Wiley Periodicals, Inc.
