Impact of the Antenna on the Sub-Terahertz Indoor Channel Characteristics: An Experimental Approach
arxiv(2024)
摘要
Terahertz-band (100 GHz-10 THz) communication is a promising radio technology
envisioned to enable ultra-high data rate, reliable and low-latency wireless
connectivity in next-generation wireless systems. However, the low transmission
power of THz transmitters, the need for high gain directional antennas, and the
complex interaction of THz radiation with common objects along the propagation
path make crucial the understanding of the THz channel. In this paper, we
conduct an extensive channel measurement campaign in an indoor setting (i.e., a
conference room) through a channel sounder with 0.1 ns time resolution and 20
GHz bandwidth at 140 GHz. Particularly, the impact of different antenna
directivities (and, thus, beam widths) on the channel characteristics is
extensively studied. The experimentally obtained dataset is processed to
develop the path loss model and, subsequently, derive key channel metrics such
as the path loss exponent, delay spread, and K-factor. The results highlight
the multi-faceted impact of the antenna gain on the channel and, by extension,
the wireless system and, thus, show that an antenna-agnostic channel model
cannot capture the propagation characteristics of the THz channel.
