Abstract
Transmission lines are introduced, emphasizing their fundamental role of simple mathematical and circuital mono-dimensional model, to describe the propagation phenomenon. The basic equations and properties are derived, and various relevant quantities (impedance, admittance, reflection coefficient, standing-wave ratio) are examined. Finally, basic matching techniques are presented.

- 1.
Using the one or the other depending on convenience, such as components in series for impedances, shunt components for admittances.
- 2.
A current reflection coefficient \(\Gamma _I\) can also be defined, but the voltage one is usually employed unless the subscript “I” is specified.
- 3.
Remember that in the case of normal incidence of uniform plane waves on a perfect conductor it was \(\Gamma _E=-1\).
- 4.
The formula for the admittance is identical, as long as each impedance is replaced with the corresponding admittance.
- 5.
\(\displaystyle \ell =\frac{\lambda _z}{4} \).
