Using ideas borrowed from topological photonics, researchers in Singapore, France and the US have designed a compact antenna capable of handling information-rich terahertz (THz) signals. Reporting their results in Nature Photonics, the team, led by Ranjan Singh at the University of Notre Dame, say that with further refinements, the design could help underpin future sixth-generation (6G) wireless networks, allowing data to be shared at unprecedented speeds.
Why 6G needs terahertz antennas
In the not-too-distant future, 6G networks are expected to enable data rates of around one terabit per second—the same as transferring roughly half the storage of a mid-range smartphone in a single second...
