The measurement of antenna VSWR by means of a Vector Network Analyzer

Description

The VSWR is an important entity when assessing the properties of an antenna. This report presents measurements of the VSWR, related to antennas, by means of a Vector Network Analyzer. The open/short/load calibration method is used as a preparation before the actual measurement in order to obtain accurate results. The way that the VSWR depends on frequency is illustrated by three measurment methods: direct measurement of the VSWR, by using 𝑆11, or by using the Smith chart. The results are compared and conclusions are drawn.
