Follow the steps:
1.Calculate your normalized impedance
2.Find the circle on the Smith Chart with a value corresponding to the real (as opposed to imaginary) part of the impedance
3.Find the line on the Smith Chart that intersects the circle corresponding to the imaginary (as opposed to real) part of the impedance
4.Mark this intersection point (A)
5.Place the tip of your compass on the center of the Smith Chart
6.Draw a diameter of the circle from your impedance point
7.Where the diameter intersects the circle on the otherside of the origin is your admittance
8.Multiply your admittance by (Yo = 1/Zo) to find the actual (de-normalized) value
