PURPOSE: A mimo/diversity built-in antenna system is provided to reduce an influence of a surface current of a printed circuit board to a human body by forming an antenna unit having a symmetrical structure. CONSTITUTION: A connection pad(500) includes a plurality of battery feeding units(502) located on a Non ground of a printed circuit board(100) and a plurality of short-circuit units(504) located on the ground of the printed circuit board. A plurality of antenna units(200) includes a short-circuit line(206) connecting with one among a short circuit line(204) with connecting one among a radiator(202), the radiator and the battery feeding units, the radiator and the short circuits. A filter unit(300) connects the short-circuit units each other. The filter unit filters an operating frequency zone of the antenna unit. The filter unit is formed into a Meander-line of a zigzag shape.
