Standing Waves, SWR & Reading a Smith Chart
Inside this lesson
- Explain how incident and reflected waves combine to form a standing wave pattern on a mismatched line
- Calculate the standing wave ratio SWR from the magnitude of the reflection coefficient
- Describe the range of SWR values and what they indicate about the quality of a match
- Identify the Smith chart as a graphical tool for visualizing reflection coefficients and impedance matching
