Abstract

A new design microstrip-fed ultra-wide band (UWB) printed multi-segment circular fractal antenna with circular polarization for
WLAN/WiMAX applications is presented. The proposed antenna comprised of a half ellipse ground plane, a fractal patch and I-shaped stub
which usable circular polarization for WLAN/WiMAX frequency bands. By embedding a I-shaped stub in the ground plane, impedance and
axial ratio bandwidth will be increased. The proposed fractal antenna has a small size of 25x25x1 mm3 and operates over the frequency band
between 2.68 and 11.6 GHz with VSWR < 2. A prototype of the UWB fractal antenna has been implemented and the S11 and axial ratio results
have been compared with the measured values.
