Title:
METHOD FOR CHANNEL IRREVERSIBILITY CORRECTION AND TEMPORAL/SPATIAL SEPARATION OF POLARIZED BEAMS, AND MULTIBEAM ANTENNA DEVICE USING SAME
Document Type and Number:
WIPO Patent Application WO/2022/098115
Kind Code:
A1
Abstract:
Disclosed are a method for channel irreversible correction and temporal/spatial separation of polarized beams, and a multibeam antenna device using same. According to one aspect of the present invention, the multibeam antenna device is provided with 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. By using two different orthogonal polarizations, the multibeam antenna device separates polarized beams temporally and spatially, and at the same time, corrects channel irreversibility that occurs due to temporal polarized separation.
