Spatial radio channel sounding for static environment at 10 GHz

We present a radio channel sounding approach for characterizing three-dimensional radio channel at 10 GHz. The measurement system consists of a vector network analyzer, two dual polarized patch antennas, programmable virtual antenna array in both link ends, together with an automatized measurement control software. The radio channel measurements are performed to validate the detected propagation paths with respect to the measurement environment. Both line-of-sight (LoS) and non-line-of-sight (NLoS) propagation conditions are measured. For LoS condition, the most significant multipath contributions are found to arise from the direct path and highly reflective surfaces. For NLoS condition, the most significant multipath contributions are found to arise from far objects and highly reflective metallic surfaces.
