摘要
A ultra-wideband (UWB) antenna with controllable frequency filtering bands is proposed and investigated by using the HFSS. The frequency rejection characteristics are realized by inserting a stub into the circular ring radiating patch and etching a stepped impedance resonator (SIR) on this stub. The simulated results showed that the proposed antenna can provide a wide frequency band to meet the requirement of UWB communication and can give two designated frequency rejection bands to filter unwanted narrowband signal interferences.
