基于微带线-槽线转换的具有陷波特性的超宽带带通滤波器
Band-Notched UWB Bandpass Filters with Mocrostrip-to-Slotline Cross-Junction Transitions
摘要
Abstract
An ultra-wideband bandpass filter with a band-notched function is proposed using a stepped-impedance multiple-mode slotline resonator and microstrip-to-slotline cross-junction transitions. The filter is implemented by a non-uniform(stepped-impedance)shorted slotline resonator,which is etched on one metal side of the substrate,is crossed at a right angle by two L-shaped open feed microstrip conductors on the opposite side. The band-notched function of the filter is achieved by the U-shaped slotlines on the two feed microstrip conductors. The passband of the filter is achieved in the frequency range of 3.20 GHz~11.4 GHz with the notched band of 5.20 GHz~5.75 GHz by the simulated and measured results.关键词
