On the application of parametric models to the transient analysis of resonant and multiband antennas

The transient responses of a resonant antenna and a fractal multiband antenna, both formed by conducting surfaces, are calculated. The surfaces are modeled by planar triangular patches and the study is carried out by solving the time-domain electric-field integral equation (TD-EFIE). Linear parametric modeling techniques are applied to considerably reduce computation time. Numerical results are compared with experimental measurements. Index Terms - Antennas, transient analysis.
