Abstract

In indoor wireless communication systems that uses millimeter-wave  (mmWave) band, the radiation pattern and polarization have a significant  impact on multipath propagation characteristics. The serious effect of antenna  directivity on indoor multipath propagation channel for mmWave band of (28,  39, 60 and 73) GHz were investigated in this paper. Four cases related with EPlane Half Power Beam Width (HPBW) of (5, 10, 60 and 90) for transmitter  antenna were incorporated with investigation. In addition, the effect of 
common building materials on signal reflection, diffraction and scattering  were presented with investigation and for both LOS and NLOS scenarios. 
Moreover, channel characterized based on delay spread, path loss and received  power, where results obtain from Wireless InSite software shows a reverse  relationship between E-plane HPBW value and of the delay spread, path loss  and received power measurements.
