A mixed model of two-dimensional (2D) genetic algorithm (GA) and finite-difference time-domain (FDTD) is applied to the automatic design of band-notched ultra-wideband (UWB) planar antennas of a finite size. The geometric shape of a band-notched UWB antenna is constructed by the method. Measured return losses, radiation patterns and gains are in good agreement with the designed ones. These results...
