Determine SWR from the Smith chart. Determine the impedance of a load at the end of a transmission line. Identify impedance-matching component values from the Smith chart. Most of you have ...

Typically, you’ll want to relate reflection coefficients to complex source, line, and load impedances. To that end, the Smith chart transforms the rectangular grid of the complex impedance plane into ...

This process uses a load to match the transmission line to the antenna, which controls the standing wave ratio (SWR). [k3ng] built his own automatic antenna tuner. First, it measures the SWR of ...
