Abstract: This project presents a compact triple band antenna for the frequency bands 5.5/6.7/9 GHz, These bands are assigned to the IEEE 802.11g and IEEE 802.16e standards. The resonant modes for WLAN, WiMAX bands are achieved by employing a rectangular slot and a met material inspired split ring structure. Also Ultra-wideband (UWB) systems have attracted significant research attention since the Federal Communication Commission (FCC) released a band of 7.5 GHz (3.1-10.6 GHz) as UWB in 2002. The proposed antenna with a compact size of 35 mm × 35 mm is fabricated and tested. The triple band antenna yields a ?10 dB impedance bandwidth of about 18.6%, 4.3% and 40.3% in 5.5, 6.7 and 9 GHz bands respectively. Stable radiation patterns with low cross polarization and high average antenna gain of 6 dBi are observed for the operating bands.
