In this paper, a single notched band at 5.2 GHz with complementary split ring resonator (CSRR) ultra-wideband (UWB) antenna and its implementation in designing of two-element multipleinput multiple-output (MIMO) with high and uniform isolation are experimentally demonstrated. The proposed UWB MIMO consists of a T-shaped stub in ground plane in between antenna elements of the size of λat3.1 GHz/4 to achieve minimum 20 dB isolation, which is almost uniform in entire UWB band. The size of the UWB MIMO antenna is 0.31λat3.1 GHz × 0.434λat3.1 GHz × 0.008λat3.1 GHz mm3, and it is printed on an RT/duroid 5880 substrate (εr = 2.2, tan δ = 0.0009), which leads to good gain and high total efficiency of the antenna in operating bands. The simulated and measured results show good agreement for the impedance bandwidth (|S11| < −10 dB) and isolation (|S21| < −20 dB) in most of the operating band, excluding the notched band at 5.2 GHz in UWB range. The simulated, measured and calculated MIMO antenna diversity parameters prove that the antenna is suitable for UWB MIMO systems.
