概要	This paper presents an efficient design of high-performance microstrip ultra-wideband (UWB) bandpass filters (BPFs) consisting of stepped-impedance resonators (SIRs) and two-section open-ended SIR stubs. An analytical study is conducted on the proposed filter prototype to show its theoretical mechanism that an exact elliptical function synthesis technique is not available. Instead, a pseudo-elliptical filter design scheme is successfully proposed for the proposed filter. As an example, a UWB BPF with a fractional bandwidth (FBW) of 110% (BW: 3.1~10.6GHz) is then synthesized, simulated, fabricated and measured. The measured frequency responses of the UWB filter compare very well with the predicted ones and successfully satisfy outdoor specifications of FCC. The fabricated filter also exhibits an easily-fabricated structure (no via-holes and the minimum gap size is 0.16mm), a compact size, low insertion loss, a flat group delay and good stopband characteristics as well.
