A dual-port MIMO coplanar waveguide antenna with left hand feed coupling control relates to a MIMO and double-frequency antenna. A medium substrate is arranged. The medium substrate adopts a rectangular medium substrate. The medium substrate is coated with a metal layer. A circle which takes a medium substrate center as a center of circle on the metal layer is removed and a residual portion is taken as a grounding plate. A rectangular medium substrate in a circle is centrally and symmetrically provided with a rectangular metal paster. Two oscillators which are vertically arranged in a ''T'' character shape and are stretched from an edge triangle central section are placed at a right portion and a lower portion of the rectangular metal paster. Two edges and a floor are separated by using a slit. Two wide seams are arranged on the floor along two diagonal lines of the medium substrate, and the floors of left and upper sides without oscillators are removed. A grounding plate is symmetrically loaded with two pairs of square CSRR left hand feed coupling control structures. The antenna can be used for 3.5GHz and 5.5GHz frequency ranges of WiMAX/WLAN.
