Fractal antenna are considered actually as the most important large band antenna, due to their design parameters that are based on fractal geometry. The long distance between two specific points of antenna and hisself similarity allow to obtain a multiple resonance frequencies (Wide Band), which is used for several application. The using of dipole antenna in form of Van-Koch curve offer multi-resonance antenna, the Nec simulator is used to design this antenna. The proposed antenna had been fabricated and measured in the antenna laboratory at two central frequencies 1GHz and 10 GHz. Both theoretical and experimental results were very closed in spite of imperfect experiment condition. The Van- Koch antenna fabrication and measurement in laboratory gives the possibility to designing and applying this antenna type, additionally we can study the change of antenna parameters ( gain, rayon diagram … ) when the fractal parameters varies.
