MULTI BAND INTERNAL ANTENNA USING MIMO

摘要

PURPOSE: A multi-band built-in antenna which uses multi-input multi-output is provided to efficiently arrange a radiator for voice communications and data communications in a small space by using a ground line of a meander structure. CONSTITUTION: A ground plane(108) is combined on the upper side of a substrate(106). A first radiator(100) is combined on the upper side of the substrate. A MIMO(Multi-Input Multi-Output) is respectively arranged to the left and right side of the first radiator and is separated as a predetermined distance. The MIMO radiator comprises a second radiator(102) and a third radiator(104) having a symmetrical structure. An isolation structure body is electrically combined with the ground plane through via hole. The isolation structure body is arranged between the second radiator and the third radiator.
