Abstract :
Fractal antennas are characterised by their special geometric characteristics, which allow a reduction of the antenna dimensions. The fractal parameters and the radiative properties of modified Koch monopoles are analysed. The geometries of the antennas are obtained by an ad hoc iterative function system algorithm for fractal curve generation. Using the method of moments for numerical calculations, the influence of the antenna geometry on the resonant frequency, current, efficiency, input impedance and radiation pattern are analysed
