For the<br /> remaining steps we consider the Smith chart as an admittance chart.<br /> Step 2: Notice that the SWR circle intersects the 1 + jb circle at two<br />This section presented three quite different designs for a matching network. One of the particular benefits of using the Smith chart is identifying topologies and initial design values. Design can then transfer to a microwave circuit simulator. The Smith chart enables back-of-the-envelope design studies.Smith Chart showing antenna load impedance “P1,” admittance point “P2,” and path “P1-to-center” for a series inductor to obtain a “perfect match” at the center point. The normalized load impedance is 1.0 - j0.8.The combination of the reflection/transmission polar plots, nomographs, and the impedance and admittance Smith chart leads to the combined Smith chart (see Figure \(\PageIndex{9}\)). This color Smith chart is the preferred version for use in design and the separate impedance and admittance versions of the Smith chart are rarely used.Point \(\mathsf{C}\) in Figure \(\PageIndex{6}\) corresponds to the normalized admittance \(0 −\jmath 3.08\). The unit circle is the zero conductance circle (and is also the zero resistance circle) and the susceptance is read from the scale adjacent to the unit circle again using as reference that susceptances in the top half of the Smith ...The Smith Chart allows easy calculation of the transformation of a complex load impedance through an arbitrary length of transmission line. It also allows the calculation of the admittance Y = 1/Z of an impedance. The impedance is represented by a normalized impedance z. Once around the circle is a line length of l/2.Electrical Engineering questions and answers.
