| 摘 要： | 针对工作于X频段的机载雷达天线的技术设计,使该天线由矩形平面天线与柱体共形,通过共面波导方式对其进行馈电。天线单元采用介电常数2.55,厚度为0.2mm的薄介质板。利用HFSS12对平面天线和共形天线进行仿真设计,对比了平面天线与共形天线的阻抗特性和辐射特性的变化。实验结果表明,共形后的天线带宽变大,增益提高,波束宽度展宽。在X波段内实现了低仰角扫描和方位面的全向扫描,实测阻抗带宽为7.0～12.5GHz,最大增益可达4dB,辐射特性稳定,满足机载天线的性能指标,可用作机载雷达天线单元。

| Abstract: | A cylindrical conformal antenna operation at X band is designed.Firstly,a planar antenna is designed and analyzed,and then it is mounted on a cylindrical surface to form a conform antenna.It is fed by CPW and the permittivity of the substrate is 2.55 and its thickness is only 0.2mm.It is simulated and optimized by using the soft of HFSS 12.Comparing the impedance characteristic and radiation patterns between the planar antenna and the conformal antenna,the experimental results show the conformal antenna has... |
