A Circular Reflectarray for OAM Generation at Terahertz Regime for 6G Applications

Abstract

A circular reflectarray antenna (RA) for generating Orbital Angular Momentum (OAM) modes in the Terahertz (THz) band is introduced. An interlaced unit cell is proposed to reach a phase variation of 328 • at 185 GHz to 188 GHz. Combining RA, OAM, and THz technologies in one structure can be utilized to reach the future requirements of 6G networks. That is due to the additional degree of freedom that OAM beams can provide for data multiplexing in short-distance wireless communication.

U-Shaped Terahertz Microstrip Patch Antenna for 6G Future Communications

“…6G has significantly lower latency than previous generations of wireless technology. This would reduce the delay between sending and receiving data, enabling real-time applications such as remote surgery, autonomous vehicles, and smart cities [1]. 6G has the potential to offer even lower latency than 5G, which could enable new applications like haptic feedback and real-time remote control of devices [2].…”
