Abstract

In this paper, an ultra-wideband (UWB) bandpass filter (BPF) with a notch-band at 5.8 GHz is presented. The proposed filter is constructed with multiple-mode resonator (MMR) using novel dumbbell stubs and one-arm-folded interdigital coupled lines in the input and output sides. The MMR consists of three pairs of shunt dumbbell stubs and a high impedance microstrip line. By adjusting the dimensions of the dumbbell stubs, the resonant modes of MMR are allocated in the UWB band. The arm-folded interdigital coupled lines are used to obtain a notch-band at 5.8 GHz. Finally, the proposed UWB BPF is fabricated. The simulated and measured results are in good agreement with each other.
