Abstract: Impedance mismatches in a radio-frequency (RF) electrical transmission line cause power loss andreflected energy. Voltage standing wave ratio (VSWR) is a way to measure transmission line imperfections. Thistutorial defines VSWR and explains how it is calculated. Finally, an antenna VSWR monitoring system is shown.
