Experimental Results of Rician K-Factor and Co-Polarization Ratio of 60 GHz Wireless Channel in an Underground Mine Gallery

In this work, experimental results of the Rician K-factor and the co-polarization ratio (CPR) are obtained and discussed from measurements conducted at 40 m CANMET underground mine gallery with Horn and Omnidirectional antennas with Horizontal (H) and Vertical (V) polarizations. These results suggest that the VV polarization offers a larger number of multipath components than the HH polarization, a correlation coefficient of about 0.86 between them, and an average CPR of about 6 dB. Furthermore, the average value of the Rician K-factor shows little or no difference between the HH and VV polarizations. The average CPR value remains around 6 dB. A correlation coefficient of multipath total power between HH and VV polarization is also found to be 0.8649.
