The paper deals with a study of diffraction on dielectric wedge(building corner) in millimeter frequency band, both theoretically andexperimentally, to provide knowledge support for ray tracing/launchingcalculations of MWS interference issues in urban areas. The mainmotivation was to find balance between reasonably reliable results andnecessary demands on calculation complexity and input data accuracy.Verification of Uniform Theory of Diffraction (UTD) was made both forperfectly conducting and dielectric wedge-shaped obstacle. Comparisonsof theoretical results and experimental measurement at millimeter wavesin anechoic chamber are presented.
