Author(s): Kim Dae Il*, Kim Un Chol, Kim Mu Song, Ri Yong Chol, Jong HyeGon and Kim Won GukIn this paper, a novel planar Ultra-Wideband (UWB) antenna with quadruple band-notched characteristics is proposed and investigated. The quadruple band-notched characteristics can be achieved by embedding three U-shaped slots on the radi ation patch and two Split Ring Resonators (SRRs) near feed line, respectively. The proposed antenna was successfully simulated and manufactured. It has a tiny size, only 17 mm × 23 mm × 0.508 mm. The proposed antenna exhibits good wideband performances over an UWB frequency range from 3.1 to 10.8 GHz with S11 less than -10 dB and with the exception of 3.27~3.7 GHz, 3.8~4.8 GHz, 5.13-5.65 GHz, 7.9~8.5 GHz frequency bands. Good agreement is obtained between the simulated results and measured results. The miniaturized structure and good characteristics make the suggested antenna a good candidate for UWB applications.
