Abstract

To prevent interference problems due to existing nearby communication systems within an ultra-wideband (UWB) operating frequency, a compact dual-band-notched UWB antenna is presented. This antenna consists of a trapezoidal ground plane with a rectangle slot, a Y-shaped monopole used as the radiator, together with a modified complementary co-directional splitering resonator (SRR) etched on the radiation patch, which leads to the desired dual notched bands for lower and upper bands of the WLAN. Experimental results show that the designed antenna, with compact size of 24×25×mm, has a wide bandwidth covering 3.05-14.2 GHz, realising dual notched bands of 5.14-5.36 and 5.74-6.07 GHz.
