We all have discussed that the impedance smith chart is more useful to deal with series components and the admittance smith chart works well for parallel components. Here ‘Y’ corresponds to load admittance and ‘Z’ corresponds to impedance.Īdmittance Smith Chart Immittance Smith Chart The equation which represents the relation between these two factors (impedance and admittance) is: To do this, one has to clearly analyze the antenna admittance instead of impedance and simply summate all those. As we all are aware that admittance has revere relation to impedance, this admittance chart works well for complicated parallel scenarios. So, to minimize the complications involved in impedance charts, these admittance charts were developed. Whereas the tricky part here is mathematical calculation when dealing with parallel elements where the elements are of inductors, transmission lines, and capacitors. The impedance chart is crucially implemented when working on series loads, all the functionality here is to summate the whole increased impedances. The picture representing impedance smith chart is shown below: Impedance Smith Chart Admittance Smith Chart This impedance of these are the main type where other types are considered as its derivatives.

These are generally termed as the usual type of smith charts as they correspond to impedance and functions in an excellent way even with huge loads constructed of many series components where these are the crucial components in the impedance matching and for other RF corresponding operations. Smith charts are plotted in two dimensions on the intricate reflection coefficient plane and the chart is generally standardized in impedance or admittance or even both through multiple colors in order to differentiate between those parameters and depending on this scaling, these are primarily categorized as three types.
