AbstractThis paper proposes improved design formulas for parallel-coupled microstrip bandpass filters with ultra-wideband multiple-mode resonators. A corrected electrical length θc has been introduced into the formulation for synthesizing these kinds of filters. Accurate predictions for fractional bandwidths Δ > 50% are achieved. Characteristic impedances of each coupled and connecting lines are calculated for achieving the required bandwidth and determining geometric parameters. Two filters with Δ = 70% and 90% are designed and fabricated. Measured results show a good agreement with those obtained from prediction. © 2009 EuMA.
