On the horizontal axis, the chart displays normalized impedance, with the center point representing a normalized impedance of 1. These circles intersect to create a grid that represents all possible impedance values. The Smith chart is composed of two sets of circles: constant resistance circles (R) and constant reactance circles (X). The chart’s primary purpose is to simplify the analysis and design of these circuits by providing a visual representation of impedance and admittance transformations. Smith in 1939 and has since become a fundamental tool for electrical engineers working with radio frequency (RF) and microwave circuits. The Smith chart is a graphical representation of complex impedance and admittance.
