The
development of 6G technology is driven by the need to meet the escalating
demands for faster, more reliable, and ubiquitous wireless communication. As
the digital landscape evolves, new applications are emerging, requiring
unprecedented data rates and bandwidth. To achieve these ambitious goals, 6G
aims to exploit the sub-THz (terahertz) frequency range, typically from 100 GHz
to 300 GHz. These frequencies are crucial for several reasons: high data rates
and bandwidth, low latency, and network density. However, utilizing sub-THz
frequencies presents significant challenges, including increased path loss,
atmospheric absorption, and the need for advanced technologies to manage signal
generation, propagation, and reception efficiently.
