Chinese Researchers Innovate Low-Cost 5G Antenna for Naval Use

Chinese researchers have developed a flexible 5G millimetre-wave antenna made from photo paper, which significantly reduces material costs by over 95%. This innovation, detailed in a study led by Yang Wendong from Liaoning Technical University and published in the Chinese Journal of Ship Research, aims to facilitate large-scale adoption of 5G technology in naval operations. The antenna is designed specifically for shipborne communications, addressing the unique challenges posed by maritime environments.

The new antenna design replaces traditional, expensive, and rigid substrates used in high-end electronics with commercially available glossy photo paper that is less than 0.3mm thick. This approach not only cuts costs dramatically but also results in a biodegradable product that is suitable for large-scale deployment. The researchers describe the paper-based antenna as a low-cost, scalable solution for the "last-mile" communication needs of naval vessels.

As navies around the world seek to integrate 5G technology into their operations, this development comes at a crucial time. The U.S. Navy, for instance, has been investing heavily in advanced solutions, focusing on low Earth orbit satellite connectivity through programs like SEA2 (Sailor Edge Afloat and Ashore). Contracts for these initiatives have reached tens of millions of dollars, with a notable example being a $99 million contract awarded to Booz Allen for deploying wireless networks across approximately 140 ships in the Military Sealift Command.

While the innovation presents significant cost-saving potential, there may be concerns regarding the durability and performance of paper-based antennas in harsh maritime conditions. Critics may question whether such a low-cost solution can meet the high standards required for military applications, particularly in terms of reliability and longevity compared to traditional materials.

The research team emphasizes that their design can "realise millimetre-wave communication antennas suitable for the complex environment of ships," highlighting the potential for enhanced communication capabilities in naval operations. The study's findings suggest a promising direction for future developments in maritime communication technology.
