5.Stub Matching The length l of the shunt line is varied until the susceptance of the stub is equal in magnitude but opposite in phase to the line input susceptance at the point of the transmission line–shunt element connection. The short-circuited stub is more practical because an equivalent short can be created by a pin connection in a coaxial cable in a waveguide.Therefore the “ double-stub” method was developed. We need to adjust two parameters to get a match. A few words about lab: We have two lab tasks on impedance matching. Single stub: We can’t “slide” the stub on the main line to adjust . d. Therefor we “adjust” the frequency. Double stub: Two stub lengths are adjusted.The single-stub impedance tuner can also be used as a matching network.

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.
