• In this letter, an ultrawideband (UWB) multiple-input-multiple-output (MIMO) antenna using a novel fence-type decoupling structure, which has high isolation in the UWB, is presented. The MIMO design consists of two half-cutting UWB antenna units that have good low-frequency impedance-matching performance because of the use of a rectangular slot on the radiation patch. Meanwhile, the isolation in the operating band is enhanced by introducing the fence-type decoupling structure at the ground of the antenna. Furthermore, the L-shaped parasitic branches are designed to heighten the impedance bandwidth and isolation in the low-frequency band, i.e., 3-3.4 GHz. The simulation and experiments show that the antenna has low mutual coupling ( S 21 < -25 dB) and a low envelope correlation coefficient (ECC < 0.004) in the UWB.
