Document Type and Number:
WIPO Patent Application WO/2019/139281
Kind Code:
A1
Abstract:
The present invention relates to a blocking wall for blocking individual antenna modules of a massive MIMO antenna from each other. A blocking wall according to one embodiment of the present invention is formed by arranging multiple staple-shaped unit partition walls in the longitudinal direction of the blocking wall, wherein the unit partition walls are designed to have optimal widths and heights according to usable frequency bands, and are arranged at predetermined intervals or less with reference to the usable frequency bands, thereby providing an antenna structure which satisfies both X-POL isolation and CO-POL isolation characteristics and can be easily fabricated in a compact lightweight design.
