The Smith Chart is a fantastic tool for visualizing the impedance of a transmission line and antenna system as a function of frequency. Smith Charts can be used to increase understanding of transmission lines and how they behave from an impedance viewpoint. Smith Charts are also extremely helpful for impedance matching, as we will see.

## The Smith Chart, Impedance Matching, and Transmission Line Circuits

The Smith chart , invented by Phillip H. Smith — , [1] [2] and T. Mizuhashi, [3] is a graphical calculator or nomogram designed for electrical and electronics engineers specializing in radio frequency RF engineering to assist in solving problems with transmission lines and matching circuits. However, the remainder is still mathematically relevant, being used, for example, in oscillator design and stability analysis. Thus most RF circuit analysis software includes a Smith chart option for the display of results and all but the simplest impedance measuring instruments can plot measured results on a Smith chart display. The Smith chart is plotted on the complex reflection coefficient plane in two dimensions and is scaled in normalised impedance the most common , normalised admittance or both, using different colours to distinguish between them. Once an answer is obtained through the graphical constructions described below, it is straightforward to convert between normalised impedance or normalised admittance and the corresponding unnormalized value by multiplying by the characteristic impedance admittance.

Engineering Electromagnetics pp Cite as. A look back at much of what we did with transmission lines reveals that perhaps the dominant feature in all our calculations is the use of the reflection coefficient. The reflection coefficient was used to find the conditions on the line, to calculate the line impedance, and to calculate the standing wave ratio. Voltage, current, and power were all related to the reflection coefficient. The reflection coefficient, in turn, was defined in terms of the load and line impedances or any equivalent load impedances such as at a discontinuity. You may also recall, perhaps with some fondness, the complicated calculations which required, in addition to the use of complex variables, the use of trigonometric and hyperbolic functions. Thus, the following proposition: Build a graphical chart or an equivalent computer program capable of representing the reflection coefficient as well as load impedances in some general fashion and you have a simple method of designing transmission line circuits without the need to perform rather tedious calculations.
