Admittance Smith Chart
The Admittance Smith Chart also known as the Y chart is the normalized admittance (Y=C+iS ) in the Γ-plane where (C,S) represents the conductance and susceptance of Y. The admittance chart can be obtained by rotating the impedance chart by 180°. The upper half of the chart represents negative values of S (or negative susceptance). The image given below represents the Admittance Smith Chart.
It is useful while working with parallel components of the circuit. The equation which establish the relationship between the admittance and impedance is:
[Tex]Y_{L} = \frac{1}{Z_{L}} = C + iS [/Tex]
Where,
YL : Admittance of the load
ZL : Impedance
C: Conductance
S: Susceptance
Smith Chart
In the field of engineering and RF transmission line design, the Smith Chart serves as a graphical measuring tool. It is a kind of graph that assists engineers in working with components. Its applications include ensuring signal and wire connections, troubleshooting signal issues, designing antennas and filters, and optimizing amplifier performance. The Smith Chart simplifies the calculations which helps in the operation of electrical systems. In RF engineering and microwave design, it is considered an asset for achieving effective functionality. In this article, we will study about Smith Chart in detail.
