Abstract

Disclosed is a MIMO / diversity antenna high isolation including a printed circuit board, a plurality of antenna elements, a current conversion element connected with a common ground of the printed circuit board apart from the antenna elements at a predetermined distance, wherein the current conversion element is coupled with the antenna elements to induce an electric current from the antenna elements into the antenna elements again via the common ground.

Description

[0001] Cross References to Related Applications [0002] This application claims priority from Korean Patent Application No. 10-2011-0086616 filed on Aug. 29, 2011, the entire disclosure of which is hereby incorporated by reference for all purposes. technical field [0003] Exemplary embodiments relate to a MIMO / diversity antenna, and more particularly, to a MIMO / diversity antenna with improved isolation for a mobile communication terminal in a narrow space. Background technique [0004] Typically, mobile communication systems use a single antenna or a built-in and external mixed antenna. However, in order to meet the demand for miniaturized and attractive mobile communication terminals that have become popular in recent years, built-in antennas are more favored. Also, as the demand for high-speed multimedia services using wireless mobile communication technology increases, the channel capacity in the mobile communication system tends to increase rapidly. Therefore, inter...
