A simple coplanar waveguide (CPW)-fed printed planar triband notched monopole antenna for WLAN/WiMAX/downlink of satellite communication systems is presented. The antenna is printed on rectangular substrate and three slots are etched on the radiator to achieve three radiating elements for notching operation. The radiator is very compact in size and simple in structure. The proposed antenna not only achieves three bands to notch 3.3-3.7 GHz for WiMAX, 5.15-5.825 GHz for WLAN, and 7.25-7.75 GHz for downlink of Xband satellite communication systems but also exhibits good radiation characteristics. The effect of each radiating element is analyzed in detail. The current distribution, VSWR, radiation pattern, peak gain and return loss characteristics are analyzed.
