Effect of Antenna’s Gain, Polarization and Channel Bandwidth on Short Range Directive Channel Propagation Loss in Indoor Environment at 5.6 GHz Band

Abstract

Propagation loss models for indoor environment are presented. The directive channel propagation loss in indoor environment at a frequency band of 5.6 GHz with a channel bandwidth of 300 and 20 MHz is measured using both vertical and horizontal polarizations. Sets of directive panel antennas are used in the measurements. RF signal generator and a spectrum analyzer are used in the measurement campaign. It is found that propagation loss is sensitive to the scenario configuration. It is noticed that the propagation loss can be modelled by two slopes propagation model giving a rise to two propagation zones. It is noticed that the first zone of propagation is almost free space propagation zone. In general, the second zone has a higher deviation from the mean value of propagation loss.
