Antenna tests

State of the art antenna laboratory for vehicles ans components

With our new antenna test laboratory – a completely reflection-free room – we cover the entire range of modern antenna tests for vehicles and components.

This laboratory ensures the effectiveness and correct setup of the wireless communication world, which includes mobile radio, including 5G, W-LAN, FM, DAB, Bluetooth, GPS and many others. With a hall size of 10.5m high, 14m wide and 12m deep, the facility offers space for simulated far-field measurements of all vehicle models and components. Part of our offer is the antenna engineering competence of our measurement and test engineers who support our customers in the creation of test procedures, the construction of test set-ups, in troubleshooting or optimisation.

In addition, at the test centre operated by SEGULA Technologies in Rodgau-Dudenhofen, just 30 km away from Frankfurt Airport, direct far-field measurements and a wide variety of use cases can be developed and tested in a private 5G network – all within a real, secure and reliable environment.
