**5. Applications examples**

In this section, some examples that integrate transmission line concepts are presented. The following examples are explained: (1) Single stub matching, (2) Bandwidth of a single-stub impedance matching system, (3) Quarter wavelength impedance matching, (4) Analysis of lossy lines. The authors developed *MATLAB* scripts that display, step by step, the graphical procedures used to solve these problems.

An example illustrating the double-stub impedance matching problem was also developed by the authors, (Pereira & Pinho, 2010).
