Assume that the load impedance Z 1 = 10 + j10 Ω is to be matched to a source impedance of Z 2 = 50 Ω. With a normalizing impedance of Z 0 = 50 Ω, the normalized impedances are z 1 = 0.2 + j0.2 and z 2 = 1 ...This introductory video describes how complex impedance and admittance are represented on the Smith Chart, and how to convert between them. A VNA is used to illustrate the complex impedance representation on a live smith chart with variable resistive and reactive components. Note that I did "mis-speak" about the circles in the chart - I ...visualized in the impedance Smith chart. The reason is that the normalized input impedance of a λ/4 terminated line (impedance inverter) is Z in = 1 Z L B 6 which is the normalized admittance of the load. Since a λ/4 transformation is equiv-alent to a 180 rotation in the Smith chart, the normalized admittance of the load canQuestion: Design a single stub tuner to match a load of Z_L = 12.5 - j 12.5 Ohm to a 50 Ohm transmission line using a short circuit stub. You solution should include the lengths of the series transmission line and stub (in lambda), and should be easily identifiable on the attached admittance Smith chart.

We obtain the load admittance as point B by rotating the point A around circle 3 through 180 ° in either direction. From this point onward, all coordinates on the Smith Chart represent normalized admittance (g + jb). We are told that the distance to Stub 1 is 0.1λ from the load.The Smith chart is plotted on the complex reflection coefficient plane in two dimensions and may be scaled in normalised impedance (the most common), normalised admittance or both, using different colours to distinguish between them. These are often known as the Z, Y and YZ Smith charts respectively.

Place your pencil at the SC point on the chart and move clockwise toward the generator (at the other end of the stub) on the rim by an amount less than a quarter wavelength (180 degrees on the chart). This is in the inductive region; moving more than 180 degrees makes the stub input look capacitive.
