A high isolation multiple-input multiple- output (MIMO) antenna with closely spaced was presented. This antenna was designed for the purpose of MIMO wireless application. The proposed MIMO antenna consists of two antennas, each operates at 2.5 GHz. The MIMO antenna system elements on a single low-cost FR4 substrate of a compact size of 47.36 mm × 29 mm and is fed by a 50 Ω microstrip. A prototype band WiMAX antenna performance was examined. The results showed that the antenna has at 2.5 GHz a reflection coefficient better than -40 dB. As a new approach, the reduction of mutual coupling depends on current cancellation between two antennas. The proposed antenna achieved better than -30 dB isolation between the two inputs. In addition, high isolation between the antenna elements and the small spacing between antenna elements, the proposed antenna has compact size reduction of approximately 60% compared to conventional patch antennas operating at the same frequency.
