In this paper, a new compact circular monopole ultrawide band (UWB) antenna with multiple narrow bands notched is proposed, designed and fabricated with a standard printed circuit board (PCB) process, which is implemented by loading a stepped impedance resonator (SIR) and a split ring resonator (SRR) on the feed line. Good agreement between simulations and measurements is achieved, which shows the antenna is a promising candidate for UWB applications.
