Abstract: Rejection of interfering bands in ultrawide band antenna has become a latest topic of research. For this purpose, etching of slots, EBG structures, folded strip configuration was used but from that only one or two notch bands are obtained. In this paper, multiple narrow bands are being notched on a circular monopole ultrawide band (UWB) antenna by using stepped impedance resonators (SIRs) along both sides of the feed line. The principle of wave cancellation is used and discussed by taking two cases with one stepped impedance resonator(SIR) on each side separately and then by combining their effects. By using two Stepped Impedance Resonators (SIRs), four bands can be rejected simultaneously.
