A novel coplanar waveguide ()-fed planar UWB antenna with quadruple band-notched property is presented. The quadruple band rejection is achieved by etching a M-shaped slot on the radiation patch and a U-shaped slot on the feed line, and adding two L-shaped parasitic strips near radiator patch and two split ring resonators (SRRs) on the back surface of the substrate. The voltage standing wave ratio (VSWR) results show that the proposed antenna exhibits good wideband performance over an UWB frequency range from 3 to 11.8 GHz with VSWR less than 2, except for four stop-bands at 3.3~3.75GHz, 5.15~5.85GHz, 7. 2~7.76GHz, 8~8.55GHz respectively. It also demonstrates a nearly omnidirectional radiation pattern and available gain. The fabricated antenna has a tiny size, only 34mm 31mm0.508mm. The simulated results are compared with the measured results and good agreement is obtained. The simple structure, compact size and good characteristics make the antenna an excellent candidate for UWB applications.
