A novel ultra wideband (UWB) bandpass filter (BPF) with dual notch bands using the coupled stepped impedance resonator (SIR) is presented. The filter consists of a square-etched multi-mode resonator (MMR) and two coupled SIRs to provide dual notch bands at 5.2 and 5.8 GHz over the standard UWB frequency range. The |S21|-magnitude and the frequency positions of the notch bands can be determined by tuning the dimensions of the coupled SIRs. The designed procedures are discussed and good agreement between the measurement and EM simulation are compared.
