Abstract

A compact ultra-wideband (UWB) bandpass filter with a fractional bandwidth (FBW) of about 110% and transmission zero at the high frequency edge is presented using a microstrip structure. The filter is based on a circuit model for an optimum stub filter consisting of only 5 short-circuited stubs separated by non-redundant connecting lines. As a result, the filter in a compact structure exhibited a selective filtering characteristic equivalent to a 9-pole Chebyshev filter. The design was successfully realized in theory and verified by full-wave EM simulation of the full layout and the experiment. The proposed filter had low insertion loss, sharp rejection, and excellent performance both inside and outside the band
