How a new terahertz antenna could unlock one-terabit 6G speeds

Researchers from Singapore, France, and the United States have developed a revolutionary silicon-based terahertz antenna that could enable 6G wireless speeds of one terabit per second by using principles from topological photonics instead of complex mechanical components. The chip features precisely engineered triangular holes in two sizes that control electromagnetic waves, creating a stable beam that covers 75% of surrounding space—30 times better than existing terahertz antennas while achieving data rates hundreds of times faster than current devices.
