A Three-dimensional Microcellular Propagation Street Model using Vectorial Analysis in UHF band

摘要

In this work we present a vectorial analysis of the three dimensional (3D) street waveguide model in UHF band. For such model the street is modeled as a 3D multislit waveguide and an ideal dipole is assumed to be the transmitting aerial. Horizontal and vertical polaraations are investigated in terms of direct incidence, ground reflection, multiple reflections on the lateral borders of the waveguide and lateral-ground (wall-road) reflections. A comparison is made between different transmitting aerial heights. After that, slits are inserted and comparisons and analysis are made. Comparisons provided with measured data show that a 3D multislit analysis together with a vectorial and gain analysis can be a very useful tool toward increasing theoretical analysis in spite of empirical analysis in the field of prediction.
