On-chip topological beamformer for multi-link terahertz 6G to XG wireless | Aug 2024
An on-chip topological beamformer for multi-link terahertz 6G to XG wireless communication achieves complete 360° azimuthal beamforming with gains of up to 20 dBi, radiating THz signals into free space with neural-network-driven customizable beams enabling up to eight simultaneous 40-Gbps wireless links.
Terahertz (THz) wireless communication holds immense potential to revolutionize future 6G to XG networks with high capacity, low latency and extensive connectivity. However, current beamformers face several challenges, including notable loss, limited bandwidth, constrained spatial coverage and poor integration with on-chip THz circuits. a,b,c Measured and simulated azimuthal radiation patterns of the intrinsic AB-type two-, three-, and four-stage topological beamformers at the horizontal plane (polar angle ϕ= 0°) at 0.325 THz.
