Admittance smith chart
The Smith chart is a graph on which you can plot complex impedances and admittances (admittance is the inverse of impedance). An impedance value on the chart is the intersection of a resistance circle, labeled on the straight horizontal line in the middle, and a reactance arc, labeled along the circumference of the "0" resistance circle.Admittance Smith Chart. Recall that on the standard or impedance Smith Chart, the circles and curves related to constant resistance and constant reactance. That is, we are looking at the impedance of an antenna, or load (Z_L). Impedances are great for dealing with series components - the impedances simply add.Admittance and the Smith Chart present. 7/7. Were not surprised! This result should not surprise us. Recall the case where a transmission line of length A = 4 is terminated with a load of impedance z L (or equivalently, an admittance y L ). The input impedance (admittance) for this case is: Z 02 Zin = ZL.
