Abstract
Signal level predictions for sector antennas in mobile networks strongly depend on the antenna pattern used in the prediction tool. For built-up areas, reflections and scattering often lead to a significant energy component at the back of the antenna, and the theoretical antenna pattern does not account for this effect. We propose a method that "truncates" the modelled antenna pattern at the back of the antenna, such that the Front-To-Back ratio of the pattern becomes smaller. A comparison of the method with measurements shows that this leads to an improved accuracy of the signal level predictions in an urban area.
