摘要: In this paper, an ultra-wideband (UWB) filter with a notch band using T-shaped step impedance resonator loaded cross-shaped open stubs has been presented. The is formed by utilizing intrinsic zero. characteristics of the new quad-mode have analyzed odd-even mode analysis method. It can be shown that it zero generates band. addition, wide tunable form 5–9.3 GHz achieved. A UWB centered at 6.25 proposed designed, fabricated, and tested. Experiment results show attenuation in frequency >22 dB while return loss simulation measurement are 22 dB/20 14.5 dB/11.2 lower upper passband, respectively, which illustrate agreement.
