Abstract

The exploitation of the sub-THz frequency for beyond 5G communications has driven significant interest in sub-THz wireless radio propagation channel characterization. However, sub-THz wide bandwidth propagation channel characterizations are not extensively studied, nor experimentally verified in the open literature. This study focuses on the modeling and simulation of indoor channel scenarios within the 500 GHz – 750 GHz sub-terahertz (sub-THz) frequency band, with the aim of enhancing our understanding of channel characteristics at these frequencies. The accuracy of the simulation platform was validated by comparing its results with measured data, thus confirming its reliability. Both directional and omni-directional antennas were utilized during simulations to investigate channel behavior in both obstructed and unobstructed environments. By varying the distance between transmitting (Tx) and receiving (Rx) antennas, channel characteristics within the 500 GHz – 750 GHz frequency band were systematically investigated.

Our primary contribution lies in the initial exploration of modeling and simulation for realistic operating scenario for indoor channel characterizations in the sub-THz frequency band, thereby addressing a critical research gap. This research serves as an indispensable reference for future design and optimization of indoor communication systems. The experimental results provide comprehensive insights into channel characteristics under varying antenna types and environmental conditions, offering valuable data support. Consequently, this work establishes a robust foundation for further research and applications, significantly contributing to the understanding of propagation characteristics in indoor channels within the 500 GHz – 750 GHz frequency band.
