Admittance Smith Chart Recall that on the standard or impedance Smith Chart, the circles and curves related to constant resistance and constant reactance.Admittance values calculated from the S-parameters were plotted on the admittance Smith chart, and the equivalent circuits with four parallel sub-circuits were synthesized by curve fitting.The combination of the reflection/transmission polar plots, nomographs, and the impedance and admittance Smith chart leads to the combined Smith chart (see Figure \(\PageIndex{11}\)). 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.

The nomalized admittance at this point is 1 + jb. 3. Beginning at the stub end (rightmost Smith chart point is the admittance of a short-circuit, leftmost Smith chart point is the a dm i t t a nc e of a n ope n- c i r c ui t ) , r ot a t e CW ( t ow a r d ge ne r a t or ) unt i l the point at 0 ! jb is reached.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.

Smith Chart. We save ourselves the trouble of evaluating (1) or (3), either to establish at the load or to infer the impedance implied by at some other location, by mapping Z/Z o in the plane of Fig. 14.6.1b. To this end, we define the normalized impedance as having a resistive part r and a reactive part x.
