Abstract :
A very compact UWB-MIMO antenna with band-notched characteristic has been proposed. The antenna printed on a PCB board consists of two notched rectangular radiators with two feeding port. A truncated ground plane is modified on the reverse side of the board. The dimension of the antenna is only 30mm×30mm×1.6mm. The achieved impedance bandwidth for S11 = -10dB covers the range of 3.7-5GHz and 5.85-10.6 GHz. The isolation is less than -15 dB. The novel UWB-MIMO antenna has ultra wide impedance bandwidth, very compact size, stable gain and almost omni-directional radiation patterns in the three-dimensional space that is suitable for various portable UWB-MIMO devices.
