For impedance matching, quarterwave transformers as well as tapers are in use. The first one is most popular : for a 2 : 1 impedance ratio, its reflection does not exceed 20 per cent over an octave-wide frequency band. Although usually much longer, tapers are mainly used if low reflection over multi-octave bands is needed. The taperlength can be reduced to… (More)
