摘要

提出了一种具有陷带特性的超宽带mimo天线。印刷在PCB板上的天线由两个带两个馈电口的缺口矩形散热器组成。在电路板的反面修改截断的接平面。天线尺寸仅为30mm×30mm×1.6mm。S11 = -10dB实现的阻抗带宽范围为3.7-5GHz和5.85-10.6 GHz。隔离度小于- 15db。新型UWB-MIMO天线具有超宽的阻抗带宽、非常紧凑的尺寸、稳定的增益和几乎全向的三维空间辐射方向图，适用于各种便携式UWB-MIMO设备。

A very compact UWB-MIMO antenna with band-notched characteristic

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.
