Standing wave and standing wave ratio

In this article, we will understand; what is standing wave, standing wave ratio (SWR), voltage standing wave ratio (VSWR) and current standing wave ratio (CSWR) in context of transmission line.


When a transmission line is not correctly terminated ,the travelling wave at the receiving end is reflected completely or partially at the termination. The combination of incident and reflected waves give rise to standing waves of current and voltage along the line, with definite maxima and minima of current and voltage along transmission line.
