In this paper, a kind of concentric split-ring slots structure is utilized to design a novel triple-band-notched UWB antenna. Firstly, a concentric split-ring slots structure that has a higher VSWR than that of a single slot at notch frequency is presented. What's more, the structure is very simple and feasible to obtain notched-band at different frequency by adjustment of the length of slot. Secondly, a triple-band-notched antenna, whose notched bands are at 3.52–3.81 GHz for WiMAX and 5.03–5.42 GHz and 5.73–56.17 GHz for WLAN, is designed by using this structure. At last, a compact size of 24 × 30 mm 2 of the proposed antenna has been fabricated and measured and it is shown that the proposed antenna has a broadband matched impedance (3.05–14 GHz, VSWR < 2), relatively stable gain and good omnidirectional radiation patterns at low bands.
