Degradation of Radio Link Capacity with Directional Antennas

Abstract

The use of directional antennas and beamforming in emerging fifth-generation systems forces the development of appropriate propagation models and computational methods that give the opportunity to be considered parameters and characteristics of such antennas/beams. This paper focuses on a simulation evaluation of a radio link capacity in which the directional antennas are used. For this purpose, a multi-elliptical propagation model is used. The analysis is carried out for two different beamwidths and a variable orientation of antennas working at 28 GHz.
