Design of Dual Slot Four Steps Stair Wideband Antenna for Bluetooth and WiMax Applications

In this paper design of microstrip line fed four stepstairs with double notch wideband antenna for wirelessapplications is proposed. This antenna operates in singlewideband frequency ranging from 2.15GHz to 5.15GHz coveringBluetooth and WiMAX applications with a total bandwidth of 3GHz. This compact antenna fed by 50ohm microstrip line is lowprofile and very easy to manufacture.
