According to one aspect of the present invention, there is provided a MIMO antenna assembly having a lightweight stacked structure, in which a calibration network, which was provided between antenna elements and filters in the related art, is provided on one printed circuit board (PCB), together with a power amplifier and a digital circuit, and filters are closely coupled to the bottom of the PCB on which the feeding network is provided. The present invention employs a strategy in which an antenna assembly is reduced to a compact size while managing phase deviation caused due to filters at an acceptable level. According to another aspect of the present invention, there is provided a calibration method, in which transmission/reception (TX/RX) calibration may be performed by a single calibration hardware component of a MIMO antenna operated by a time division duplex (TDD) scheme and may be performed in real time during the operation of the MIMO antenna, and the MIMO antenna employing the calibration method.
