Abstract :
In this study, an improved ray tracing algorithm for the use of the uniform theory of diffraction and geometrical optics was employed because of its high efficiency and reliable prediction accuracy. Rain attenuation was considered in this method, and relevant simulation was carried out at 20 GHz. The results showed that the effect of rain attenuation on the prediction results was quite obvious at this frequency.
