Abstract

In this paper a fractal antenna, namely the modified Sierpinski gasket monopole is presented that possesses a small physical size, high efficiency and the ability to allocate both the 2.4 and 5.2 GHz ISM-bands. The modified element respects the multiband behavior of the gasket since the input impedance characteristics of the upper bands maintain their symmetry. Several modification techniques are proposed making the monopole very flexible in terms of band allocation and fine-tuning. Results of MoM & FDTD -methods of simulations of the circuit- and the field-antenna parameters are presented and discussed
