New Physical Discrete UHF Multilayer Propagation Model for Urban Areas
关键词:
Discrete model, path loss, urban areas, scattering, and multilayer propagation model.摘要
In this paper, a newly developed discrete
multilayer propagation model using scattering theory is
studied using rectangular lossy multilayer dielectric
plates which model the walls, the streets, and avenues in
urban areas. The model is presented to study radio wave
propagation in street environments and to compare it with
previous theoretical and experimental studies. Good
agreements are found. Using the developed model, it is
possible to calculate the c ontributions of direct and
scattered wave separately. The simulations reveal that the
developed model can be applicable for a broad band of
frequencies. This model can be used effectively for
prediction of loss characteristics in a situation when two
antennas are located below the rooftops in conditions of
direct visibility.
