The results presented here were obtained using a channel sounding testbed, which was specially designed to study the radio propagation in the 5-6 GHz frequency band with high resolution in terms of angle-of-arrival (AOA) and time-of-arrival (TOA). Measurements were made at different indoor locations and the influence of the receiver surroundings on polarization cross-coupling was analyzed as a function of the azimuthal and elevation AOA. Significant cross-coupling was measured in locations where multi-paths arrive with oblique AOA with respect to the horizontal plane (thetas=90deg). The cross-polarization was characterized with high resolution in azimuth and elevation, which enabled the study of the spatial distribution of depolarized multipaths. The amount of power due to cross-polarized multipaths was estimated for a vertically polarized transmitter antenna located in different indoor environments. The advantages of using multi-element antennas and polarization diversity were made evident, as well as the importance of the relative location of transmitter and receiver and the 3-D distribution of the nearest scatterers.enantenna radiation patternpatch antennaswirelessdelay spreadpolarizationangledeconvolution techniquesantenna radiation patternpatch antennaschannel capacitychannel soundingtransmitterselectromagnetic wave propagationElectric field measurementdirection-of-arrivalindoor propagationelectromagnetics polarizationConference Proceeding10.1109/CCECE.2006.277655
