Transparent antenna seeks to solve 5G mmWave FWA challenges

German smart antenna startup Alcan Systems has invented a transparent antenna that you stick on a window to allow high frequency spectrum to get through.
The embrace of millimetre wave by the 5G era was celebrated as opening up vast new swathes of spectrum real estate that would enable hitherto unimaginable wireless data rates. There was just one problem, however – the propagation characteristics. While traditional low-frequency radio waves penetrate walls and windows as if they weren&rsqu
