Here, you are going to be shown how to use a millimeter-wave radar to detect the breathing rate of a human? This technique is highly instrumental for searching for survivors in a disaster zone.
This video demonstrates how a two-port measurement is conducted using a Vector Network Analyzer (VNA) in the electrical engineering lab at Vietnamese-German University (VGU). It provides an overview of the equipment setup, measurement process, and key parameters such as S-parameters, helping students understand practical applications of high-frequency circuit analysis.
Here, we want to show you how a 2-port measurement of a branch line coupler can be done using VNA at VGU.
A hands‑on engineering demo from VGU’s lab showing how a two‑port measurement is set up and executed using a branch line coupler. The host walks through the equipment setup, calibration, and data capture steps—great for students or anyone learning microwave circuit testing.
