There is another set of lines called constant Reactance lines. The outermost resistance circle cutting the horizontal line on the extreme left represents zero resistance while the circle cutting the horizontal line on the right extreme right represents infinite resistance. The resistance values which these constant resistance circles represent are marked on the horizontal diameter at the points of intersection of these circles and the horizontal line. These circles are known as constant resistance, R circles.Įach circle represents a fixed resistance that is all points on a particular resistance circle represent the same resistance. The first set of lines referred to as Constant Resistance lines form circles, all tangent to each other at the right hand of horizontal diameter. Smith chart is basically an impedance chart containing two set of lines. Smith chart consists of two types of circles: Thus normalized load impedance is given by:.Impedances are always normalized with respect to characteristic impedance, Z 0 in Smith chart to avoid construction of one chart for each Z 0.So it gives the indication of impedance at transmission line as one moves along the line. In other words, it is a graphical plot of normalized resistance and reactance in the reflection coefficient plane.
