Single-Stub Matching As shown previously, the input impedance (admittance) of a shorted transmission line (a “stub”) is purely reactive. By placing a stub in parallel with another transmission line, the reactive component can be cancelled, leaving a pure-real input impedance. This can be used to achieve a perfect match. Z 0 = 50 Z in = 50 Z L dNote the stub is attached in parallel at the source end of the primary line. Single-stub matching is a very common method for impedance matching using microstrip lines at frequences in the UHF band (300-3000 MHz) and above.
