A novel UWB bandpass filter based on multi-stub loaded half-wavelength resonator

Abstract

In this paper, a novel multi-stub loaded half-wavelength resonator (MSLHWR) is proposed, which exhibits multi-mode resonance and is characterized by three resonant modes of interest. Then, an UWB bandpass filter is designed on it, which can cover the desired UWB bandwidth. Especially, λ/4 open-circuited stubs are introduced at input/output ports, which can… (More)
