Design of a Sierpinski patch antenna around 2.4 GHz/5GHz for WiFi (IEEE 802.11n) applications

In this paper, a low-cost dual-band printed antenna that employs Sierpinski fractal geometry is proposed for possible integration to IEEE 802.11n WLAN standards access points. The designed antenna covers two wireless spectrum bandwidth, they are the ISM 2.4 GHz and the U-NII 5 GHZ. The antenna geometry is confined within a compact size of 75 × 75 × 1.8 mm ³ . The antenna is mounted on partial ground and fed by microstrip line. It is modelled and optimized using the well-known CST software and the results in terms of reflection coefficient, VSWR, Bandwidth and power Gain are illustrated and compared to previous published literatures.
