Abstract

This paper studies the impact of the line-of-sight (LOS) and non-LOS (NLOS) path loss at 300 GHz frequency band in a multipath propagation setting. The aim is to model the impact of the multipath signal components in stochastic indoor environment as a function of antenna patterns, and the number of the multipath signal components. The outcome of simulation model is that the general free space path loss is an accurate measure of the propagation loss in the LOS case. In the NLOS cases, the free space path loss model remains accurate with slight increase in the path loss exponent from 2 to approximately 2.2 to 2.7 depending on the material properties. Such low path loss exponents are caused by highly directional antennas omitting the most the interference from the propagation environment. As a consequence, the channel appears as a free space channel with some additional loss caused by reflections in NLOS directions.
