For future versions or any proposals, please contact withThe Imaginary Smith Chart was used in [12], [13] to design a narrowband match to the aperture admittance of an evanescent-mode open-ended waveguide. In [12] this resulted in a narrowband antenna ...admittance (blue) mapping. From the chart above, we find this admittance value is approximately y L =−017 028.j.. Now, you may have noticed that the Smith Chart above, with both impedance and admittance mappings, is very busy and complicated. Unless the two mappings are printed in different colors, this Smith Chart can be very confusing to use!

Admittances in Parallel Add. Since the admittance of an inductor is entirely imaginary (that is, Re [y_ind]=0), the result of adding an inductor in parallel is to change the susceptance of the antenna (load). That is, we are only altering the imaginary part of the antenna's admittance.Read the following instructions to use CocoDoc to start editing and writing your Admittance Smith Chart: At first, seek the “Get Form” button and tap it.

It turns out, that if we combine the impedance Smith Chart with the admittance Smith Chart, we will have no trouble doing this. The combination is known as the Immittance Smith Chart. Immittance Smith Chart. If we overlay the impedance Smith Chart on top of the admittance Smith Chart, we get the Immittance Smith Chart of Figure 1: Figure 1. Using the immittance Smith chart, we can easily find two-element lossless matching networks. Let's examine this through an example. Assume that the load impedance Z 1 = 10 + j10 Ω is to be matched to a source impedance of Z 2 = 50 Ω.

The Smith System was developed by Harold Smith in 1952.Thus, an admittance Smith chart can be obtained by rotating the whole impedance Smith chart by 180°. This is extremely convenient, as it eliminates the necessity of building another chart. The intersecting point of all the circles (constant conductances and constant susceptances) is at the point (-1, 0) automatically. With that plot, adding ...
