Abstract

This letter presents analysis of diffraction over multiple shadowing screens at frequency range of 10-18 GHz. Up to ten pieces of thin metal sheets with dimensions of 130 × 100 cm at variable spacing were used as diffraction screens. The aim of this study is to investigate the total shadowing effect of multiple knife-edge diffractions at frequencies above the legacy cellular systems. The results show the necessity to adjust the Walfisch-Bertoni path loss model for the higher frequencies in the future fifth-generation systems.
