Chinese researchers have developed a flexible 5G millimetre-wave antenna made from photo paper which they say slashes material costs by more than 95 per cent, potentially removing a key barrier to large-scale naval 5G adoption. They described a paper-based flexible multiple input multiple output (MIMO) antenna engineered specifically for shipborne 5G communications in a study published in the peer-reviewed Chinese Journal of Ship Research and led by Yang Wendong of Liaoning Technical...
