Abstract
AbstractIn this paper, a compact quintuple notched-band ultra-wideband bandpass filter with high selectivity and wide bandwidth is proposed. The filter adopts an approximate closed-loop C-shaped stepped impedance resonator to generate triple notched bands, and uses Hilbert fractal curve slit and L-shaped resonator to create single notched band, respectively. Multiple notched-band are centered at 5.29, 6.61, 7.92, 8.95, and 9.93 GHz to eliminate undesired interference from coexisting wireless services of WLAN, C-band, and X-band. Additionally, two transmission zeros are introduced to enhance the sharp skirt selectivity up to 0.944. This filter could exhibit high sharp selectivity and wider bandwidth simultaneously. The filter is fabricated on a RT/Duroid 5880 substrate (ɛr = 2.2 and thickness = 0.787 mm) and measured to verify the simulation results. Both simulation and measurement are in well agreement, showing the good performance of the filter.
Highlights
Ultra-wideband (UWB) bandpass filter (BPF), as one of the key component in the UWB system, influences the overall system performance [1]
Different units, i.e. an ACLC-stepped impedance resonator (SIR) is located under the center of the plane, and the L-shaped resonator is loaded on interdigitalcoupled feed lines along with a Hilbert fractal curve slit that is etched on the center plane of the stepped-impedance open stub
Triple notched bands are - implemented in the UWB BPF by introducing an ACLC-SIR
Summary
Ultra-wideband (UWB) bandpass filter (BPF), as one of the key component in the UWB system, influences the overall system performance [1]. A quintuple notched-band UWB BPF with high selectivity (0.944) and wide bandwidth (2.94–11.05 GHz) is proposed. MMR is the basis of designing quintuple notched bands UWB BPF.
