Instantaneous Directional Channel Measurements at 14 GHz and 160 GHz via a Virtual Circular Array

Year: 2025

Type: conference-paper

Abstract: In this paper a novel frequency-scalable rotary platform design is introduced which allows for flexible directional channel measurements using different types of antennas, and which can also be used with frequency extenders for measurements up to the THz region. The measurement platform has been applied to measure the channel properties including the direction of arrival at the FR3 frequency 14 GHz and in the Dband at 160 GHz in a large hall indoor environment with LOS distances up to 40 m. The results show very good agreement of strong path components for both frequencies as well as interesting dependencies of delay spread, angular spread, and Ricean Kfactor on distance and frequency and can be used to parameterize a path loss model.
