In this paper, a new planar monopole antenna is designed and fabricated for IMT and WiMAX applications. The antenna is based on the use of Sierpinski triangle with a modified ground structure consisting of T-shaped and small rectangular slots printed in the ground. The entire area of the proposed antenna is 55x50mm2 and it is printed on an FR-4 epoxy substrate and fed by a 50 Ohm microstrip line. This new design helps in enhancing both the reflection coefficient and the bandwidth. The electrical performance of the fractal antenna is investigated by the use of CST-MW and HFSS. The simulated results present good performance in terms of matching input impedance and radiation pattern. The electromagnetic results of the fractal antenna are in a good agreement with measurement results.
