摘要
采用MATLAB实现的宽带天线特征模分析程序,设计了一种高隔度的双极化超宽带天线。天线整体尺寸为30 30mm,在3.1~11.5 GHz频段范围内匹配良好,且隔离度高于20 d B。此天线由两个互相垂直的馈电单元组成,通过共用一个正方形辐射贴片减小了天线尺寸,并分别在单元馈线间和地板间添加隔离枝节提高了隔离度。该天线可用作分集和多输入多输出通信。
By utilizing the characteristic modes based Matlab program for wideband antenna analysis, a dual-polarized ultra-wideband(UWB) antenna with high isolation is proposed. With a compact size of 30×30 mm~2, the antenna covers a range from 3.1 to 11.5GHz with isolation better than 20 d B. The radiator of the antenna is shared by two perpendicular feeding structures, thus to reduce the size of the antenna a lot. The isolation of the antenna is improved by adding two isolation stubs, the one is between the two feeding lines of the elements, and the other is between the grounds. The proposed antenna is a good candidate for diversity/MIMO communication systems.
