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.

Antenna device

A compact antenna apparatus for a mobile communication system includes: a radome having at least one frequency band radiating element provided therein; at least one phase shifter portion which is provided in an inner side of the radome and which is connected to the radiating element to adjust a tilting angle of the radiating element; and a rotary knob portion which is provided so as to be exposed to the outside of the radome and which is directly coupled to the phase shifter portion to drive a phase shifter.
