OH4VNA: Accurate and reliable S11 parameter measurements of mobile device antennas SPEAG’s OH4VNA measures the reflection coefficient (S11) without electrical cables by a bi-directional radiofrequency over-fiber link. In this video, we compare return loss measurements performed using traditional coaxial cables with such performed using OH4VNA to validate simulation results of an antenna. We outline the advantages of the latter – namely, the radiofrequency transparency of the optical fiber solution allowing characterization of the antenna under test under galvanically isolated conditions. |
