| 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 3.0–9.5 GHz while the group delay variation in the passband is in the range of 0.5◦. |
