Design of a Prefractal Monopolar Antenna for 3.4-3.6 GHz Wi-Max Band Portable Devices

In this letter, the design of a miniaturized monopolar prefractal antenna for the 3.4-3.6 GHz WiMax band is presented. The geometrical configuration of the monopolar antenna, printed on a planar dielectric substrate, has been synthesized by means of a particle swarm optimizer in order to minimize the linear dimensions of the device and to obtain voltage standing wave ratio (VSWR) values within specifications. The results of numerical simulations are shown and compared, in terms of VSWR, with the experimental measurements
