It is a complex topic, especially where directional antenna systems are concerned, as there are several potential bottlenecks in a directional array. I touched on the black art of AM antenna broadbanding before. More basic Smitch chart usage information in this video: If the load impedance is 85 ohms and the reactance is +j60, then the normalized Smith chart point would be. 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.
