Satellite 2026 – NTN and Flat Panel Arrays

Why It Matters

These developments accelerate the integration of satellite links into 5G and IoT networks, expanding coverage where terrestrial infrastructure is lacking, while low‑SWaP flat‑panel antennas lower deployment costs for aviation, maritime, and defense users.

Key Takeaways

• 5G NTN drives satellite integration for remote IoT connectivity.
• Flat‑panel arrays gaining market share in aviation and maritime sectors.
• Airbus partners with Greenerwave for low‑power multi‑orbit antennas.
• Kymeta launches Kestrel u5, sub‑1 ms beam switching for defense.
• SWISSto12 invests €73 M ($79 M) in HummingSat GEO production.

Pulse Analysis

The Satellite 2026 conference in Washington, D.C., served as a barometer for the satellite communications industry, with non‑terrestrial networks (NTN) and flat‑panel antenna technology dominating discussions. Attendees noted that 5G NTN is moving from concept to deployment, enabling direct‑to‑device and IoT services in regions where fiber or cellular coverage is impractical. Simultaneously, flat‑panel arrays are reshaping in‑flight connectivity and maritime communications, offering lighter, lower‑profile solutions that meet the stringent SWaP (size, weight, and power) constraints of modern platforms.

Key product launches reinforced these trends. Airbus Defence and Space deepened its partnership with Greenerwave, leveraging the latter’s ultra‑low‑power flat‑panel designs to support multi‑orbit constellations across Ku and Ka bands. Kymeta’s Kestrel u5 terminal demonstrated sub‑millisecond beam switching, a capability critical for defense vehicles and high‑speed platforms. NexSat’s ACE antenna introduced a conformal, electronically steered Ku/Ka solution that eliminates traditional radomes, while SWISSto12’s new €73 million ($79 million) cleanroom signals a commitment to scaling GEO satellite production for faster, cost‑effective launches. Complementary technologies—from Aaronia’s real‑time spectrum analyzers to Empower RF’s GaN amplifiers—highlight a broader ecosystem focused on high‑frequency performance and rapid market entry.

The convergence of NTN and flat‑panel technologies signals a shift toward ubiquitous, low‑latency satellite connectivity. As operators integrate satellite links into 5G core networks, the demand for multi‑orbit, multi‑band antennas that can seamlessly transition between LEO, MEO, and GEO constellations will grow. Low‑power, compact flat‑panel arrays reduce launch costs and enable deployment on aircraft, ships, and unmanned systems, expanding the addressable market. Investment levels, exemplified by SWISSto12’s €73 million facility, suggest confidence in sustained growth, positioning satellite communications as a cornerstone of future global connectivity strategies.
