Abstract

A novel ultra-wideband (UWB) bandpass filter is proposed, designed and imple- mented. The UWB bandpass filter (BPF) is designed for short-circuited stubs with defected ground structure (DGS). The rectangular slot provides attenuation pole to suppress the spuri- ous in the stopband. The quarter-wavelength short-circuited stubs are used to realize the lower stopband, and the etching on the ground plane with rectangular slots is employed to attenuate the upper stopband. Both simulated and measured results show that the filter has a good per- formance, including an ultra-wideband bandpass (3.1-10.6 GHz), a small insertion loss, a group delay variation of less than 0.12 ns.
