New Challenges for European Space Industrial Policy
Global Policy, EarlyView.ABSTRACT The European space industry is globally competitive but faces challenges due to fragmented governance, reliance on commercial markets, and increased international competition. The European Union (EU) has become a major stakeholder in this sector, with a ‘fragmented institutional market’ shaped by policies, initiatives and programmes at ...

MXene‐Coated 3D Printed Horn Antennas for Ku Frequency Band
Advanced Materials Technologies, Volume 11, Issue 9, 6 May 2026.An additive manufacturing approach to 3D printing horn antennas and coating them with Ti3C2Tx MXene is proposed. Rapid fabrication of lightweight, high‐performance antennas operating in the Ku‐band (12.4–18 GHz) has been demonstrated. The MXene‐coated antennas exhibit comparable electromagnetic performance to conventional, costly aluminum ones, with ...

Location‐Assisted Graph‐Based User Scheduling in Multi‐User MIMO LEO NTN Systems
International Journal of Satellite Communications and Networking, Volume 44, Issue 3, Page 275-287, May/June 2026.ABSTRACT This paper addresses user clustering and scheduling for multi‐user MIMO low Earth orbit nonterrestrial network systems in full frequency reuse. Since the number of on‐ground user terminals is usually much higher than the number of on‐board LEO satellite antennas, user scheduling becomes a fundamental task.

Advanced Fade Mitigation Techniques for Q/V Band SATCOM Systems
International Journal of Satellite Communications and Networking, Volume 44, Issue 3, Page 288-296, May/June 2026.ABSTRACT Adaptive fade mitigation techniques, such as smart gateway diversity (SGD), are essential in addressing atmospheric fading affecting the operation of high throughput and very high throughput satellite systems at Ka‐band and beyond. Specifically, the Q/V‐band, offering up to 5 GHz of available spectrum, is very attractive for future high data ...
