Abstract

A MIMO antenna assembly of a lightweight laminated structure is disclosed. One aspect of the present invention provides a MIMO antenna assembly of a lightweight laminated structure, wherein a calibration network, which has been placed between an existing antenna element and a filter, is formed on one board together with a power amplifier and a digital circuit, and the filter is closely attached to the lower portion of a PCB on which a feeding network is formed. The present invention adopts a strategy to reduce the antenna assembly to a compact size while managing a phase deviation caused by the filter at an allowable level. Another aspect of the present invention provides a calibration method in a MIMO antenna operating in a Time Division Duplex (TDD) scheme and a MIMO antenna using the same, wherein the calibration method can perform a TX/RX calibration in a single calibration hardware configuration and perform the calibration in real time during operation.
