| 摘 要： | 本文设计一种共面波导馈电的超宽带天线（UWB），其阻抗带宽达到341%。所设计的天线印刷在尺寸为28×21×1.6mm3，介电常数为2.65的聚四氟乙烯介质基板上。并利用电磁仿真软件HFSS对影响天线性能的主要物理参数进行仿真、分析和优化,得到天线的理想尺寸。最后，对优化的超宽带天线进行制作，测试。实验结果表明,该天线比传统微带贴
片天线性能有了较大的提高,从而证明利用共面波导馈电的超宽带天线设计方法，能够实现兼容多种通信系统的可行性和有效性。

| Abstract: | A Coplanar waveguide-fed ultra-wideband (UWB) antenna was presented in the paper. The impedance bandwidth isabout 341%. The proposed antenna was printed on 28×21×1.6mm3 polytetrafluoroethylene with relative dielectric constant 2.65. Thekey parameters are simulated, analyzed and optimized using the electromagnetic simulation software HFSS. The ideal dimensions ofthe antenna are obtained. The optimized antenna was also manufactured and tested. The results show that the performance of CPWbroadband microstrip slot antennas can be greatly improved compared to traditional microstrip patch antennas, and the feasibility andeffectiveness of the CPW feed and the rectangle slot was also verified. |
