Design of a compact circular micro strip antenna with band notched Ultra-Wide Band (UWB) characteristics has been proposed. The proposed antenna consists of circular radiating patch with a micro strip line type feed structure and employs a simple Defected Ground Structure (DGS) in a rectangular shape to achieve UWB operation. A notch is also designed to avoid the function of the antenna at 5.5GHz to reject WLAN2 band from 5.15 to 5.825GHz. The crux of this design strategy is that a 'C' shaped slot has been embedded onto the patch antenna to achieve band-stop filtering action at above mentioned frequency.
