To sum up this page so far, the Smith Chart is a plot of the reflection coefficient.Smith Charts were originally developed around 1940 by Phillip Smith as a useful tool for making.Z0. With modern computers, the Smith Chart is no longer used to the simplify the calculation of.
Figure 1 should look a little intimidating, as it appears to be lines going everywhere. This section of the antenna theory site will present an introduction to Smith Chart basics. Well now begin to explain the fundamentals of the Smith Chart. Note that Z0 can be viewed as the impedance of the transmitter, or. Hence, the Smith Chart is a graphical method of displaying the impedance of an antenna, which. In Figure 2, we are plotting the set of all values for the complex reflection coefficient, along the. The center of the Smith Chart is the point where the reflection coefficient. The outter ring of the Smith Chart is where the magnitude of. Along this curve, all of the power is reflected by the load impedance. From equation 2, with Z050 Ohms, a reflection coefficient of 0.5 corresponds to a load impedance ZL150 Ohms. Since is entirely real, the point lies along the real gamma axis (x-axis) in Figure 3. From Equation 2 and using Z050, we note that corresponds to a load impedance. From Equation 2 and with Z050, corresponds to a load impedance ZL -i50 Ohms. That is. That is, a VSWR 1 would be the center of the Smith Chart, and VSWR3 would be a circle centered around the center of the Smith. Chart, with magnitude 0.5. Circles centered at the origin of the Smith Chart are constant-VSWR circles. Note that the outer boundary of the Smith Chart (where 1) corresponds to a VSWR of infinity. However, if you like videos, here is another medium of presenting the. An example antenna impedance is plotted on the Smith Chart and explained. The Smith Chart Movie Is ToThe goal of this movie is to present the information using a different method (video instead of webpage). The Smith Chart tutorial is shown on this page, in video format.
