“…Other work reported in [4] [5] has extended such models to consider diffraction off all four sides of a small diffracting object, while also it has incorporated the effects of the directive transmit and receive antenna patterns. A point of clarity should be noted in this paper whereby double knife edge diffraction can have other meanings such as two consecutive knife edges [6]- [8]. Therefore from this point onwards double knife edge diffraction will be considered as diffraction off two edges of a tall narrow object.…”

A new simple and accurate model defined as shield edge diffraction is derived and validated suitable for frequencies above 10GHz diffracting around obstructions that are narrow compared to the Fresnel zone width. The model includes new simple Fresnel diffraction parameters similar to those used with traditional knife edge diffraction, which can in the same way be integrated into deterministic and empirical path loss models. Capability of the model extends beyond current single and double knife edge models whereby it includes the effects of the antennas' far field distances as well as their gain and phase patterns, which subsequently have a severe effect on the diffraction loss in short range links. The models are validated using both anechoic chamber as well as real environment based measurements at 10-12GHz and 26GHz.Index Terms-Diffraction, shield edge, knife edge.
