Disclosed are a method for temporal/spatial polarized beams and channel non-reciprocity correction and a multi-beam antenna apparatus using the same. According to one aspect of the present disclosure, a multi-beam antenna apparatus includes an array antenna including transmission antenna elements used for forming a plurality of transmission beams and reception antenna elements used for forming a plurality of reception beams. The multi-beam antenna apparatus separates polarized beams temporally and spatially by using two kinds of different orthogonal polarizations, while corrects a channel non-reciprocity which occurs due to temporal polarization separation.

Disclosed are a spatial multiplexing method and apparatus using polarization in a multi-beam system. As the spatial multiplexing method using polarization in a multi-beam system, an embodiment of the present invention provides a spatial multiplexing method including determining different phases and different polarizations to be applied to a first beam and a second beam, precoding a signal so that the first beam and the second beam have the determined different phases, and converting polarization of the precoded signal so that the first beam and the second beam have the determined different polarizations.
