Abstract
Propagation measurements in the recently allocated 3.7-3.98 GHz band that incorporate polarization state information are described and analyzed. Co-located cross-polarized receive antennas show large variations in received signal strength as a function of the polarization state of the transmitter. Combining or selection must be applied to these antenna outputs. The circularly polarized outputs of a hybrid coupler show much smaller variations. Cross polarization discrimination analysis suggests that potential diversity gains exist for combining the two circularly polarized hybrid coupler outputs.
