A triple-band multi-input multi-output (MIMO) antenna is presented.The proposed antenna consists of a C-shaped monopole antenna that provides dual-band resonant antenna. By protruding an L-shaped parasitic strip on the ground plane, a third band as well as enhancement of the isolation between two ports in MIMO array is achieved. The proposed antenna can cover 2.12.6, 3.34, and 5.46 GHz, which are allocated for WLAN and WiMAX applications. The proposed triple-band antenna structure is used in different two-element MIMO arrays. Simulation results show that the S11, S12, and S22 of the MIMO arrays are independent of the position of the two-element. The results show good S-parameters, high peak gain and radiation efficiency, and stable radiation patterns among the triple-band coverage.
