Abstract

In this paper, an ultra-wideband (UWB) band-pass filter with dual band-notch characteristic is proposed and its performance is verified numerically. The proposed UWB filter is realized by using stubs and folded stepped impedance resonators (FSIRs) to provide two desired notch bands at 5.0 GHz and 8.0 GHz, respectively. The center frequencies of these band notches can be easily tuned by adjusting the dimensions of the stubs and folded stepped impedance resonators. The proposed UWB filter with dual band-notched function can provide a wide band- width of 2.29–11.51 GHz. The simulated results are given to show that the proposed UWB band-pass filter with compact structure can provide desired notch bands and wide bandwidth, which make it suitable for UWB communication applications.
