Compact ultra-wide band microwave filter utilizing quarter-wave length short-circuited stubs with reduced number of vias

We present here a novel pattern with compact size of ultra-wide band microstrip filter. The filter is originally modeled from five poles quarter-wavelength short-circuited stubs. It is then, transformed into a new compact butterfly-like pattern. This new "butterflyshaped" pattern consists...
