Abstract

An ultra-wideband (UWB) antenna with a narrow frequency notch is presented. The antenna has been fabricated on a Duroid 5870 substrate and occupies an area of only 30times35 mm². Starting from a trapezoidal planar patch exhibiting a VSWR smaller than 2.5 in the 3.5-10 GHz band, a frequency notch at 5.65 GHz is introduced by two slots near the coplanar waveguide feeding the patch. The measured return loss shows a good agreement with the simulation results and proves that this kind of antenna is suitable for reducing the detrimental interference effects of WLAN, operating around 5.5 GHz, on UWB radio links.
