Wideband building material characterization for 6G applications

Studying the attenuation and distortion of ultra wideband signals in indoor environment is important for designing wireless communication systems. An experimental work was conducted in this paper to characterize the effect of some building materials on ultra wideband propagation. The measurements were taken for the range from 750 MHz to 20 GHz, where this band is used for 6G applications. Pre-processing techniques were applied to remove the effect of noisy bands and multipath effect. The dielectric constant and loss tangent are calculated as a function of frequency for the considered materials. The dielectric constant and the frequency are negatively correlated, while the loss tangent behavior is not monotonic.
