| 摘 要： | 通过单极子和高介电常数(相对介电常数为38)陶瓷介质谐振器的耦合设计了一种新型类齿状UWB单极子天线,以实现天线超宽频带的目的。采用软件HFSS进行仿真,并对天线模型参数进行优化,得到最佳设计效果。结果表明,该天线频带宽度为2.6~20.0 GHz(S11≤–10 dB),相对带宽达到了154%,满足超宽带天线要求。该天线实现小型化超宽带的同时,在整个UWB匹配频段内,具有良好的驻波比和方向图特性,较好地兼顾了各方面的性能。

| Abstract: | A new dentation UWB monopole antenna was designed,whose bandwidth was further expanded through the coupling between the monopole antenna and a dielectric resonator with high relative permittivity being 38.The parameters of the antenna were simulated and optimized with HFSS,the best antenna design was got.Results show that the bandwidth of the antenna is within 2.6-20.0 GHz(S11≤-10 dB) meaning a relative bandwidth of 154%.The antenna meets the requirements of the ultra-wideband antenna and has good VSWR and omni-directional radiation performance. |
