Abstract	The new work makes three UTD (uniforn geometrical theory of diffraction) based path-loss prediction models and their experimental validations for urban micro-cellular mobile radio communications. The three models apply to the base station and mobile antennas much lower than the surrounding buildings and can be written in explicit forms for both vertical-and horizontal-polarization transmission and reception. Comparisons of their predictions with measurements at 900.5 and 1800 MHz in shadow zones of urban areas confirm the three models experimentally. The results demonstrate that fast two-dimensional (2-D) models which do not require a building height database can provide acceptable accuracy for micro-cellular mobile radio propagation predictions in urban environments. The methodology of this work is to deternine in advance significant rays to use, from a particular geometry of the buildings in an urban area. It appears suitable here for 2-D modeling for parallel-street problem and irregular side-street problems. It has the potential to be used in practical design of micro-cellular mobile radio systems.
