| 摘 要： | 设计了一种具有宽频带特性的柱面共形天线,通过改变柱体曲率半径、长度和介电常数等参数,详细分析了其变化对共形天线性能的影响。结果表明:柱体各个参数的变化会导致天线的谐振频率、阻抗带宽以及辐射特性发生显著的改变。对设计宽频带共形天线时共形载体的选取提供了可靠依据。实际加工制作了天线,测量结果表明:该天线具有宽频带特性,可用频段覆盖2~16 GHz,在工作频段内具有较好的辐射特性,增益稳定。

| Abstract: | A cylindrical conformal antenna with wideband characteristic is proposed and analyzed.By changing the radius,length and permittivity of the cylinder,the effects of these parameters on the impedance characteristics and radiation capabilities of the antenna are analyzed.The simulated results show that the resonant frequency,impedance bandwidth and the radiation patterns all greatly change with the changing of the radius,length and permittivity of cylinder.Simulated results give credible ideas to choose suitable carrier when design wideband conformal antennas.The conformal antenna is fabricated and measured and the results show that the antenna has a high wide band capability with operation bandwidth from 2~16 GHz.The radiation property and stable gain can be achieved at the operation frequency. |
