This paper is intended to give the newcomer to RF terminology a brief overview of SWR, return loss and reflection coefficient. Instead of concentrating on mathematical derivations or formulas which can make simple ideas seem complicated, this paper will endeavor to explain the fundamental principals ...
Return loss is the loss of power in the signal returned/reflected by a discontinuity in a transmission line or optical fibre.

So, in summary, we express insertion loss in decibels, and it is the ratio of incident power to transmitted power. Furthermore, we can summarize that return loss, which we also express in decibels is the ratio of incident power to reflected power. Therefore, we can see how the two types...
By connecting the output of the noise source to the SWR-bridge input, and the antenna to the DUT port the return loss or SWR of the antenna can be measured with the Airspy. To get a wider than 10 MHz view of the spectrum Anders uses the SpectrumSpy software for the Airspy which is ...
Voltage Standing Wave Ratio (VSWR) is taught lightly in our CWNA course and hints at return loss, but some students have faced challenges in grasping the concepts. The problem stems from the fact that a significant amount of physics and mathematics suppo

MANUAL RETURN LOSS MEASUREMENTS Sam Wetterlin swetterlin@comcast.net 10/5/08 This paper describes the procedure for using a reflection bridge (a/k/a “return loss bridge”) to manually measure return loss (easily converted to SWR if desired). “Manual” means we don’t have all the automat...
can expect decent performance. The return loss indicates at what frequencies you can expect a good impedance match, and thus a good standing wave ratio (SWR). The lower the return loss the better the impedance match and thus less power is wasted in the antenna meaning better receive ...
