In electrical engineering, a transmission line is a specialized cable or other structure designed to conduct electromagnetic waves in a contained manner. The term applies when the conductors are long
One of the most common types of transmission line, coaxial cable
A type of transmission line called a cage line, used for high power, low frequency applications. It functions similarly to a large coaxial cable. This example is the antenna feed line for a longwave radio transmitter in Poland, which operates at a frequency of 225 kHz and a power of 1200 kW.
A simple example of stepped transmission line consisting of three segments
The Smith chart is a circular nomogram used in radio frequency engineering to solve transmission line and impedance-matching problems. It plots a complex reflection coefficient on a grid of normalized

…only shown as an arrow marked Z 0 on the left side of the diagram above), the impedance transformation circle is off-centred along the x axis of the Smith chart whose impedance representation is usually normalized against Z 0 . At higher frequencies, the reactive parasitic effects of real world lumped elements…
