Thus, if the input resistance is 50 ohms and the load impedance is 50 ohms j0, then the normalized Smith chart point would be 50/50 or 1. To normalize, the load resistance and reactance are divided by the input resistance. In the center of the Smith chart is point 1, which expresses a perfect match. Impedance and reactance are expressed as ratios of value units like VSWR. The first thing to understand about a Smith chart is normalization. pdf version available here: smith-chart. They can be very useful for AM antenna broadbanding. ![]() Smith charts offer a great way to visualize what is going on with a particular antenna or transmission line. They look complicated, but are really pretty easy to understand and use, once you get around all those lines and numbers and stuff. I have been fooling around with Smith Charts lately.
