MIMO ANTENNA HAVING PARASTIC ELEMENT

摘要

PURPOSE: A MIMO(Multi-Input Multi-Output) antenna is provided to diversify a circuit structure by controlling the distance between antenna elements through a bridge. CONSTITUTION: A MIMO antenna comprises a plurality of antenna elements(110,210), a plurality of parasitic elements(120,220), and a bridge(130). A plurality of antenna elements are symmetrically arranged in one side of a substrate. A plurality of antenna elements are operated in a single frequency band or a multi frequency band. A plurality of parasitic elements are arranged in the other side of the substrate. The bridge interlinks a plurality of parasitic elements. A ground plane is formed on the substrate to be spaced apart from a plurality of antenna elements and a plurality of parasitic elements.
