1. An antenna unit comprising:
a radio unit (RU) printed circuit board (PCB);
a filter unit disposed on one surface of the RU PCB;
a calibration network PCB disposed on one surface of the filter unit;
a metal plate disposed on one surface of the calibration network PCB;
an antenna PCB disposed on one surface of the metal plate; and
an antenna array mounted on one surface of the antenna PCB,
wherein:
the metal plate includes a stand-off;
the calibration network PCB includes a hole through which the stand-off passes;
the stand-off includes a head and a body, the head being inserted into an insert region of the metal plate, and the body protruding in a direction of the one surface of the filter unit along the hole of the calibration network PCB;
the filter unit includes a screw that penetrates portions of the one surface and another surface of the filter unit and is coupled to the stand-off; and
the stand-off and the screw fix and couple the metal plate, the calibration network PCB, and the filter unit.
