Abstract
A new ultra wideband bandpass filter (UWB-BPF) using arrow coupled lines and U-slot defected
ground structures (U-DGS) is proposed. The input and output feeding lines are connected to the
coupled lines placed on the conductor side of the substrate while the U-slot DGS was etched from the
ground side below. The effect of U-DGS slot dimensions on the operating bandpass of the filter was
studied. The filter was simulated using both IE3D and HFSS simulators. The simulation results are in
good agreement with the realized filter. The filter operating passband extended over the UWB
frequency 3.0 to 9.5 GHz while the group delay variation in the passband is in the range of 0.5 degree.
