m4 wireless GmbH

m4 wireless is a deeptech start-up with the vision to leverage METAMATERIAL-TECHNOLOGY with its groundbreaking new capabilities for advanced, eco-friendly wireless communication systems.

At MWC2026 we demonstrate how dipole and monopole antennas like PIFAs can be drastically reduced in size (factor of 5!) by means of engineered, scalable, simple-to-manufacture metamaterial structures.
We seek partners to utilize this technology to MINIATURIZE ANTENNAS for small drones, robots, IoT-devices, automotive applications...

Moreover, we show a wide-band HIGH-EFFICIENCY all-dielectric METASURFACE (static IRS) for mmWave and FR3 that can be TAILORED to the application scenario to extend the coverage range and to cover shadowed areas. With our 3D-printing-technology it takes only 8 hours from specification to delivery of the customized IRS.
We are interested in cooperations with campus network providers to demonstrate our just-in-time concept and also our new CONTINUOUSLY RECONFIGURABLE intelligent surface (RIS).

Metamaterials will shape the future of RF technology. Join us & bring your RF component to the next level. METAMATERIALIZE it!
