A comparison between the measured and theoretically predicted site-shielding factor (SSF) of an obstacle resembling a building is made. The SSF, which expresses the additional attenuation caused by an obstacle on the propagation path, is measured along a cylindrical arc behind the obstacle at a frequency of 50 GHz. The theoretical model uses the uniform geometrical theory of diffraction (UTD) including corner, edge-to-edge, and edge-to-corner diffraction. The agreement between the measured and theoretically derived results is excellent. The strong polarisation dependence of the SSF encountered appears to be due to slope diffraction.
