PURPOSE: A multiband multi-in multi-out antenna is provided to arrange a first antenna and a second antenna within a narrow space on a substrate without a separate structure, thereby minimizing the entire size of an antenna. CONSTITUTION: A first antenna(106) and a second antenna(108) are symmetrically arranged in left and right sides. The first antenna includes a first radiator pattern(110) and a second radiator pattern(120). The first radiator pattern includes a ground connection pattern(111), a loop formation pattern(113), and a patch(115). The ground(104) is formed with predetermined area on the lower end part of a substrate(102). A band-stop filter interrupts a frequency component generated due to a coupling between the first antenna and the second antenna.
