What is meant by the VSWR of an antenna? - MobileMark
The Voltage Standing Wave Ratio (VSWR) is an indication of the amount of mismatch between an antenna and the feed line connecting to it.This is also known as the Standing Wave Ratio (SWR).The range of values for VSWR is from 1 to ∞ .. A VSWR value under 2 is considered suitable for most antenna applications.

Microwaves101 | Voltage standing wave ratio (VSWR)
Calculating VSWR from impedance mismatches. The mismatch of a load Z L to a source Z 0 results in a reflection coefficient of:. Γ=(Z L-Z 0)/(Z L +Z 0). Note that the load can be a complex (real and imaginary) impedance. If you can't remember in which order the numerator is subtracted (did we just say "Z L-Z 0" or Z 0-Z L "?), you can always figure it out by remembering that a short circuit (Z ...

VSWR (Voltage Standing Wave Ratio) - Antenna Theory
The voltage standing wave ratio (VSWR) is defined. VSWR is a measure of the reflected power on a transmission line. VSWR is a function of the characteristic impedance of the transmission line and the impedance of the antenna. VSWR specs (specifications) are introduced, along with formulas for mismatch loss and return loss in relationship to VSWR.
