Antennex, has signed a contract with the European Space Agency (ESA)’s Connectivity and Secure Communications for a next generation reverberation chamber.
Eindhoven, The Netherlands, 16th of December 2025 – Antennex, a provider of advanced characterization solutions for integrated antennas, has signed a contract with the European Space Agency (ESA)’s Connectivity and Secure Communications for a next generation reverberation chamber. Supported by ESA’s Advanced Research in Telecommunications Systems (ARTES) Competitiveness & Growth program, the agreement kickstarts a 2-year development track for a chamber fit for the needs of the aerospace industry. The activity includes the development of a functionality that enables spatial measurements of integrated antennas.
In the project, Antennex will design and construct a new, larger reverberation chamber. This increased volume will support the testing of larger devices such as satcom terminals and modules for satellites. This will also expand Antennex’ capability for testing frequencies in the L- and S- bands, while maintaining its capacity to measure devices at Ku and Ka band.
“This agreement with ESA marks a significant milestone in the expansion of our product portfolio,” said Anouk Hubrechsen, CEO of Antennex. “By introducing a larger testing chamber, we’re positioned to better serve the aerospace sector’s accelerating growth and demand for high-precision OTA RF measurement.”
“ESA is committed to supporting emerging European enterprises as they solidify innovation and competitiveness in the space industry,” said David Gomez Otero, Head of the Space Segment Section within ESA’s Connectivity and Secure Communications. “By developing a larger reverberation chamber with spatial measurement functionality, we’re enabling for the precise characterization of integrated antennas across multiple frequency bands. This project with Antennex strengthens Europe’s testing capabilities for next-generation satellite communications.”
About ESA The European Space Agency (ESA) provides Europe’s gateway to space.
ESA is an intergovernmental organisation, created in 1975, with the mission to shape the development of Europe’s space capability and ensure that investment in space delivers benefits to the citizens of Europe and the world.
ESA has 23 Member States: Austria, Belgium, the Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Ireland, Italy, Luxembourg, the Netherlands, Norway, Poland, Portugal, Romania, Slovenia, Spain, Sweden, Switzerland and the United Kingdom. Latvia, Lithuania and Slovakia are Associate Members.
ESA has established formal cooperation with four Member States of the EU. Canada takes part in some ESA programmes under a Cooperation Agreement.
By coordinating the financial and intellectual resources of its members, ESA can undertake programmes and activities far beyond the scope of any single European country. It is working in particular with the EU on implementing the Galileo and Copernicus programmes as well as with Eumetsat for the development of meteorological missions.
Antennex develops advanced over-the-air test systems tailored for integrated antennas and complex RF front ends. Headquartered in Eindhoven, the company works with leading aerospace, telecom, and automotive customers to streamline performance characterization in increasingly integrated environments.
