Multiple diffraction propagation path loss due to the successively located different shaped building roofs are important for mobile communication. In the literature, building roofs are considered as wedge shaped structures. In this paper, building roof is modelled with a more realistic structure and the propagation path loss between the transmitting antenna and the receiving antenna is calculated.
