ABSTRACT: This paper presents a planar ultra-wideband
(UWB) bandpass filter with sharp out-of-band rejection performance. The filter is
formed by a folded multiple-mode resonator to realize high performance in an operation
band from 3.3 to 10 GHz with a very compact size of 20 mm × 20 mm × 0.5 mm. An extra
notched band centered at 5.8 GHz is further accomplished by etching a Hilbert fractal
curve slit on the filter without the necessity of readjusting the geometrical parameters.
The simulated and measured results are in good agreement.
