Measure VSWR to quantify transmission line flaws

Posted: 30 Apr 2013 ?? ?Print Version ?Bookmark and Share

Keywords:Impedance? radio-frequency? Voltage standing wave ratio?

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