OH4VNA: Accurate and Reliable S11 Parameter Measurements of Mobile Device Antennas
Watch our latest video to learn how to accurately and reliably measure the reflection coefficient (S11) of electrically small antennas with SPEAG’s OH4VNA system
Until now, the exact measurement of a mobile device antenna has been a trial and error process due to the use of coaxial cables changing the antenna impedance and the overall electrical size of the device. With OH4VNA, we present a new solution in which the traditional coaxial radiofrequency measurement cable is replaced by a non-disturbing fiber-optic system requiring no external power. The main application of OH4VNA is return-loss-characterization of electrically small antennas in mobile, hand-held, body-worn, or implanted devices.

DYMSTEC, SPEAG, and ZMT held their 20th annual hardware and software workshop in South Korea. The successful event featured several presentations, live demos, and product exhibitions, and was supported by a live English-Korean translation service.
We are pleased to announce the latest software release of our DAK product line, version 126.96.36.199. This important maintenance release further improves the accuracy, repeatability, speed, and user experience of measurements with our DAK/DAKS and DAK-TL systems.
Z43 is expanding into beautiful new quarters at Ankerstrasse / Kräuelgasse, which include some much-needed meeting spaces. The new workplace, the former headquarters of Fabric Frontline, was inaugurated July 1 with an "Info Day" presentation in the "Salon", followed by an Apéro.
