Analytical and Experimental Investigation of Ultra Wideband Channel Characteristics in the Presence of Door/Window Glass

  • 22 Accesses


This paper presents ultra-wideband channel characteristics in the presence of float glass slab as obstacle of varied thickness (4 mm, 8 mm, 12 mm, 19 mm) in an indoor environment. Two different sets of measurements are performed related to variation in the Tx–Rx antenna position and rotation of the glass slab at angles varying from 0° to 90° to mimic the glass door/window movement. The channel characterization of various Tx–Rx links are carried out by analyzing various parameters such as RMS delay spread, peak magnitude of the power delay profile and received signal amplitude. Different direct path, partial and total obstructed path situations are observed depending on the position of the Rx antenna, rotation angle of the glass slab and also the position of the Tx–Rx antennas with respect to the glass slab. Results indicate higher multipath and RMS delay spread for glass edge scattering and direct through glass propagation. Decrease in signal strength is more prominent for 12/19 mm glass thickness in comparison to 4 mm glass sheets for partial NLOS and NLOS scenarios. For LOS situations, channel parameters for various glass thickness show similar range of values and are comparable with the scenario when no-glass in present.
