Single Semi-Fractal Antenna Embracing Wireless Standards of GSM to UWB

Abstract

A novel microstrip-fed printed triangular-shaped semi fractal monopole antenna (TSSFMA) is presented. The fractal unit-cell is based
on a triangular geometry. The antenna construction is achieved by assembling the scaled down unit-cells to satisfy fractal space-filling
property. It is shown that by increasing the order of iteration, an antenna is realized which is able to operate across a wide spectrum of
wireless standards such as GSM, UMTS, GPS, PCS, WCDMA,WIMAX, WLAN (802.11b) and UWB. The antenna is compact with a size of
55×42×1 mm3 and it operates across a frequency range extending between 1.53 and 12.79 GHz with VSWR < 2. In this paper, the
improvement process of the impedance bandwidth is presented and discussed.
