Abstract :
A simple wideband bandstop filter that yields equal ripples in both the pass- and the stopbands is described. The filter comprises only two resonant stubs and a connecting transmission line and has a transmission response almost identical to that of a third-order elliptic function filter. The practical bandwidth is limited to 130-160%.
