An ultra-wideband (UWB) microstrip filter with a fractional bandwidth (FBW) of more than 100% is designed and demonstrated. This UWB microstrip-filter design is based on a circuit model for an optimum short-circuited stub transmission-line filter whose unit elements or connecting lines are nonredundant. A comparison study is carried out to show the advantages of this type of filter versus the conventional design, whose unit elements are redundant. The theoretical, simulated, and experimental-results of the designed optimum UWB microstrip filter are prepented. © 2005 Wiley Periodicals, Inc.
