New anechoic chamber of the Professorship of Microwave Engineering at Chemnitz University of Technology offers many possibilities for research, teaching, and transfer
Professorship of Microwave Engineering at Chemnitz University of Technology recently put the new chamber into operation and intends to use it to research new mobile radio standards and IoT applications

Prof. Dr. Ralf Zichner from Chemnitz University of Technology examines a typical measurement set-up in the high-frequency absorber chamber to determine the performance of a new antenna development stage. To Zichner's right is a GSM mobile base station antenna (824 MHz to 960 MHz) without a cover, as found on many building roofs.
In research and development, so-called anechoic chambers are used to conduct research with absolute freedom from sources of interference. It is possible to generate specific frequencies in the chamber to research wave propagation or so-called magnetostriction, i.e. the deformation of magnetic materials by magnetic fields. This allows, among other things, the development of smaller antennas. In addition, the anechoic chamber can be used to determine whether any electronic systems, such as notebooks, lamps, or TVs, comply with the guidelines for the emission of electromagnetic waves. Prof. Dr. Ralf Zichner, Professor of Microwave Engineering at Chemnitz University of Technology, recently put such a facility into operation for his professorship.
"Ours is a custom-made chamber. We were able to incorporate our specifications, which makes it unique," says Ralf Zichner. He adds: "Our chamber is used for research, teaching and also for transfer to industry. For example, we need the special conditions in the chamber for almost all of our research activities. These include research on mobile communications standards such as 5G and 6G, Internet-of-Things applications, radiometrics, and remote sensing."
