Get Carta Di Smith Online

The Smith chart is a graphical tool for determination of the reflection coefficient and impedance along a transmission line. It is an integral part of microwave circuit performance visualization, modern computer-aided design (CAD) tools, and RF/microwave test instrumentation.

The Smith chart resides in the complex plane of reflection coefficient G = Gr + Gi = | G |ejq = | G |/u. At point A, G = 0.6 + j0.

Smith Chart first looks like Black Magic, but it is a straightforward and useful tool that will help us better understand impedance/admittance transformations and transmission lines. Smith Chart is a polar plot of the reflection coefficient.

The Smith chart is made up of multiple circles, and segments of circles arranged in a way to plot impedance values in the form of R ± jX (Fig. 1). A horizontal line through the center of the main circle represents the resistance with R = 0 at the far left of the line and infinite resistance at the far right.
