Abstract
This letter provides a model using dyadic Green's functions for predicting the electric field in mixed paths for UHF. A new approach is used considering propagation in vertical layers to obtain new equations. The development of the model was accomplished in a mixed city–river–forest path located in the Amazon region. Measurement data were collected from a digital TV broadcasting transmitter. A comparative analysis was carried out among the proposed model, ITU-R P.1546-5, measurement data, and ITU-R P.1546-5 using Millington's curve fitting. The measurement data and the proposed model are in a good agreement. The results confirm the efficiency and applicability of the proposed model with RMS error not greater than 1.5 dB.
