title = "A compact ultra-wideband bandpass filter with high return loss characteristic",
abstract = "This paper presents a high return loss ultra-wideband bandpass (UWB) filter with a loose coupling of coupled line. A proposed structure consists of shunt short transmission line and a coupled line. By analytically study, a high return loss can be obtained by located a proper five transmission poles in the passband. For an experimental validation, the UWB filter was designed at a center frequency of 6.85 GHz. The measured results agree well with the simulation results. From the measurement, the insertion and return losses were better than 1.5 dB and 20 dB within the operating band from 3 to 11.1 GHz (FBW = 113.2 \%).",
