By etching a half-wavelength hook-shaped slot on the ground and adding quarterwavelength rectangle-shaped strips in the patch, a novel triple band-notched ultra-wideband (UWB) antenna is proposed. The triple band-notches are used to prevent interferences from existing bands at 3.3–3.9 GHz, 5.15–5.35 GHz, and 5.725–5.825 GHz. Fed by coplanar waveguide, the antenna is printed on a 30∗30 mm2 substrate. The parameters affecting antenna performance are simulated and analyzed. The simulated and measured results show that the proposed antenna achieves a wide bandwidth from 3GHz to 11 GHz with triple band-notches. Radiation patterns and gain are also investigated and analyzed.
