摘要 提出了两种新型的平面超宽带(UWB)天线,这两种天线的馈电单元和辐射单元都采用了矩形与圆形的组合结构,使得天线的工作带宽展宽。通过数值分析和实验结果表明,两种天线可获得较宽的工作带宽,能满足UWB天线3.1~10.6GHz的带宽要求。同时,具有良好、稳定的全向辐射特性和较高的增益,有较好的实用价值。 Two kinds of novel planar UWB antennas are proposed. For improving the bandwidths of antennas, the semicircle and rectangle structure are combined as the radiator and feed cell of antennas. The simulated and measured results show that these two kinds of antennas can meet the need of UWB system in the range of 3.1 - 10. 6GHz. Meanwhile, relative stable and good omni-directional radiation performance and high gain have also been achieved.
