Smith chart is a type of graph paper used in electrical engineering to plot variances of complex transmission impedance along its length. If you are author or own the copyright of this book, please report to us by using this dmca report form. The smith chart can be used to simultaneously display multiple.īlack and White Smith Chart Download Printable PDF Templateroller Once around the circle is a line length of l/2. The smith chart is simply a graphical calculator for computing impedance as a function of re ection coe cient z = f(ˆ) more importantly, many problems can be easily visualized with the smith chart this visualization leads to a insight about the behavior of transmission lines all the knowledge is coherently and compactly represented. To respond to your other comments, s11 is a polar plot of complex reflection overlaid on top of the smith chart, where the origin (0,0) is at the center of the smith chart (50 ohm location) so you can plot both s11 and z on the same graph. Half is “capacitive” = negative imaginary part. It also allows the calculation of the admittance y = 1/z of an impedance.
