Other transmission line matching techniques – and in particular, single stub matching (Section 3.23) – typically result in structures which are significantly smaller.These matching lines are called matching stubs. One of the major advantages here is that with a line which has an adjustable short on the end of it, we can get any reactance we need, simply by adjusting the length of the stub. How this all works will become obvious after we take a look at an example. Figure \(\PageIndex{2}\): A shortened stubFigure 2 also hints at an important property of transmission lines; a transmission line can move us from one constant-resistance circle to another.

A shorted stub transforms to an infinite impedance at odd multiples of a quarter wavelength. A quarter-wave stub is a convenient way of supporting an inner conductor without an insulator, and accessing the inner conductor with water cooling, for example. Stubs are also used in matching a load to a source by introducing an intentional reflection. 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.
