An ultra‐wideband antenna is designed using genetic optimization and the finite‐difference‐time‐domain (FDTD) method. Efficiency is enhanced by using the Green's function method (GFM) as an absorbing boundary condition (ABC) close to the antenna surface, and as a propagator to the radiated field at any observation point at each iteration step. © 2005 Wiley Periodicals, Inc.
