Abstract
The present disclosure provides a shield wall for shielding multiple individual antenna modules of a massive MIMO antenna from each other. A shield wall according to at least one embodiment of the present disclosure is formed by a plurality of staple-shaped unit partitions arrayed longitudinally of the shield wall, wherein the unit partitions are designed to have optimal widths and heights according to the frequency band in use, and are arranged at a predetermined interval or less with reference to the frequency band in use, thereby providing an antenna structure which satisfies both the X-POL isolation and CO-POL isolation characteristics and can be easily fabricated in a compact, lightweight design.
