Mimo(multi input multi output) antenna without phase variation

PURPOSE: A multi input multi output antenna without phase variation is provided to suppress interference between antennas by the formation of a decoupling structure on the central part of a dipole antenna structure. CONSTITUTION: Both unit structures(210,220) have the symmetrical structure corresponding to a central part in the shape of a meander. The unit structure is connected to an earth plate(260) by the medium of feeding units(240,250) for supplying electrical energy. Both unit structures are contiguous to the earth plate and are installed as a 3D stereo structure. Both unit structures are mechanically connected by a U-shaped decoupling structure(230). The decoupling structure for the connection of both unit structures is located between both unit structures.
