INTERNAL MIMO ANTENNA CAPABLE OF FREQUENCY TUNING

摘要

Disclosed in the present invention is a frequency tunable embedded MIMO antenna. According to the present invention, the frequency tunable embedded MIMO antenna comprises a printed circuit board; a plurality of antenna devices; a current converting device spaced apart from the antenna devices by a predetermined distance and connected with a common ground of the printed circuit board to guide a current induced from the antenna devices by a coupling with the antenna devices, back to the antenna devices through the common ground; and an active device disposed on the printed circuit board where a short point connected to the current converting device is positioned and adjusting impedance characteristics of the current converting device by being connected to the current converting device. The active device varies operation frequency bands of the antenna devices by adjusting the impedance characteristics of the current converting device.
