Anritsu and VTT Technical Research Centre of Finland have demonstrated a major advance in D-band wireless communications by validating a beam-steering transmitarray antenna system using advanced test equipment. The achievement confirms the feasibility of stable, high-capacity wireless links for next-generation backhaul, industrial, defense and future 6G networks.
Using Anritsu’s precision test equipment and VTT’s steerable transmitarray antenna, the teams achieved high-speed wireless links across the 110–170 GHz D-band. Link performance and beam-steering behavior were assessed under realistic over-the-air (OTA) conditions using wideband modulated signals up to 8 GHz bandwidth. This system-level characterization, from signal generation to OTA performance, confirmed multi-gigabit data rates in the tens-of-Gbps range, including 20 Gbps over 1 m and reliable operation up to 7 m, setting a new benchmark for D-band connectivity.
The demonstration features a lightweight, scalable transmitarray antenna developed by VTT, incorporating advanced phase-shifting elements and vector-modulator MMICs. Its electronically steerable design provides rapid, precise beam control without mechanical movement, maintaining signal strength under changing conditions. Supported by Anritsu’s state-of-the-art test equipment, the results reflect a proven, instrumentation grade measurement approach that ensures reliability and scalability for future deployments.
“Anritsu is proud to collaborate with VTT to advance the practical use of D-band wireless technology. Together, we have validated performance levels that bring high-frequency wireless links closer to real-world deployment,” said Jonathan Borrill, CTO, Test & Measurement, Anritsu.
“This milestone shows how strategic partnerships turn deep tech into competitive advantage. By combining VTT’s steerable transmitarray expertise with Anritsu’s precise instrumentation-grade validation, we shorten adoption cycles and scale D-band from the lab to live networks — creating growth opportunities across critical infrastructure, manufacturing, defense, 6G and beyond,” said Tauno Vähä-Heikkilä, Director, Strategic Partnerships, VTT.
Anritsu and VTT will now engage with industry partners to evaluate use cases and prepare the technology for upcoming field trials and deployments, marking a landmark step toward realizing the potential of D-band wireless for next-generation networks.
