A Review on Radiowave Propagation Models for Very High Frequency and Ultra High Frequency Band

Abstract

Radiowave propagation model is an empirical mathematical formulation for characterization of radiowave propagation as a function of frequency, distance and other conditions. This study explains the various attenuating factors prevalent in radiowave propagation. It highlights the various types of radiowave propagation; its classification based on their propagation paths; its layers in the atmosphere, its frequency bands and propagation mechanism. The study also entails the various radiowave propagation models and their application in VHF and UHF band.
