Abstract :
An ultrawideband (UWB) antenna using a step impedance resonator that eliminates signal interference at 5 GHz wireless-LAN as the first rejection band and can adjust the second rejection band is proposed. The proposed antenna is satisfied to cover full UWB with return losses and push the second rejection band to out of working band. The design process is done with numerical analysis, and the optimization is given by particle swarm optimization algorithm.
