In this communication, we propose a metamaterial inspired conventional elliptical slotted coplanar waveguide (CPW) UWB antenna for dual band-notched features. Initially, the operating frequency range is from 4GHz to 12 GHz. To filter the undesired WLAN (5-6GHz) and uplink and downlink of X-band satellite communication systems (7.25 to 8.39 GHz ) frequency bands ,we are loaded respectively a symmetrical dual split ring resonator metamaterials SRR as a defected ground plane slots (DGS) and a single split ring resonator metamaterial (SRR) as a strip on the top edge of the radiating slotted elliptical antenna.The performance of the antenna is simulated both by CST Microwave Studio and Ansoft HFSS .To analyze the effects of the SRR slot and strips ,the surface current distribution is used. The antenna gain versus frequency is acceptable except the notched band regions, its value is reduced from its normal to be a negative value in (5-6 GHz) and (7.25 to 8.39 GHz ) suppressed bands.
