Abstract Aiming at the band trap’s requirement in wireless body area network system (WBAN), a band-notched ultra wide band (UWB) antenna was designed and a U-shaped slot was opened on the radiation patch. The current distribution of the UWB antenna was changed for radiation patch with U-shaped slot. In addition, the narrow-band interference signal of WLAN (5.15～5.825 GHz) was inhibited by adjusting U-shaped slot’s dimension. Quantum-behaved particle swarm optimization (QPSO) was utilized to obtain the optimal parameters of antenna and fractal slot. The antenna was simulated by the HFSS simulation software and tested by Agilent N5230A network analyzer. The simulation and test results showed that the antenna has achieved a good impedance matching at 3.8 GHz, and the bandwidth was covering 3.1 GHz to 10.6 GHz. What’s more, the narrowband interference signal of WLAN (5.15～5.825 GHz) was inhibited effectively and the antenna directivity has a good performance except the trap points. In conclusion, the optimization design method of UWB antenna is effective.
