2024年2月27日 · The Smith Chart is a graphical tool that helps in analyzing and designing transmission lines and impedance-matching networks.
Smith Charts - Antenna Theory
The Smith Chart is a fantastic tool for visualizing the impedance of a transmission line and antenna system as a function of frequency. Smith Charts can be used to increase understanding of transmission lines and how they behave from an impedance viewpoint.
Smith Chart Basics - Microwaves101
What is a Smith chart? It's really just a plot of complex reflection overlaid with an impedance and/or admittance grid referenced to a 1-ohm characteristic impedance. That's it! Transmission coefficient, which equals unity plus reflection coefficient, may also be plotted (see below).

How to Use a Smith Chart: Explanation & Smith Chart Tutorial
The Smith Chart is the most used tool for microwave engineers to visualize complex-valued quantities and calculate the mapping between them. It consists of two sets of circles for plotting various parameters of mismatched transmission lines.
RF engineering basic concepts: the Smith chart. F.Caspers. CERN, Geneva, Switzerland. Abstract. The Smith chart is a very valuable and important tool that facilitates interpre- tation of S-parameter measurements. This paper will give a brief overview on why and more importantly on how to use the chart.
