WPF Smith Chart Control. Visualize the impedance and admittance of a transmission line. Visualize data with a high level of user interactivity.Smith Chart with Admittance I Often it is easier to work with admittance, rather than impedances (e.g. parallel loads). Let us see how the Smith chart changes when working with admittance I Consider the admittance Y at any point on a line with characteristic admittance Y 0. The normalized admittance y = Y Y 0 = g + jb = 1 r + jximpedance, zL = ZL/Z0, is inside the 1 + jx circle on the Smith chart, then the circuit of Figure 5.2a should be used. If the normalized load impedance is outside the 1 + jxcir-cle on the Smith chart, the circuit of Figure 5.2b should be used. The 1 + jxcircle is the resistance circle on the impedance Smith chart for which r = 1.

The normalized load admittance, y L,—corresponding to z L = 2 + j—is marked on the Smith chart of Figure 13. Figure 13. Smith chart showing the normalized load admittance, y L. A clockwise rotation of λ/8 due to the series line on the load side transforms y L to y 1, as depicted above.The Smith Chart 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. z = Z Z0Parallel stub tuning is depicted in Figure 1. The parameter d is chosen, so admittance is Y = Y 0 + j B, and susceptance - j B. Figure 1. Series stub tuning is depicted in F igure 2. The parameter d is chosen so the impedance is Z = Z 0 + j X, where reactance is - j X. Figure 2. Admittance and impedance are related with Y = 1 X.

March 24, 2023 by Dr. Steve ArarAdmittance of an AC circuit is the reciprocal of its impedance. Using the impedance value one can easily derive the Admittance values of the circuit. Admittance ‘Y’ can be measured as Y = 1/Z. where ‘Z’ is the impedance, Z = R+jX. So, admittance ‘Y’ can be written as, Y = 1/R+jX. Thus, the formula of Admittance when derived from ...
