摘要: 为提高高功率径向线螺旋阵列天线的功率容量,实现GW级高功率微波定向辐射,通过对螺旋线单元天线和阵列布局的改进,设计了功率容量大于1 GW的4圈48单元磁探针径向线螺旋阵列天线,并对其进行了理论分析、数值模拟和试验研究.测量结果表明:在3.6~4.1 GHz范围内,天线增益大于22 dB,轴比小于2 dB,口径效率大于55%.Abstract: In order to raise the power-handling capacity of a high-power radial line helical array antenna and realize the directional radiation of GW-level high-power microwaves,a GW-level 4-ring 48-element radial line helical array antenna using H-coupled probes was designed based on the improvements of element helical antenna and array arrangement.Theoretical analysis,numerical simulation and experimental measurement of this radial line helical array antenna were carried out.The result of the experimental measurement shows that in the range of 3.6 to 4.1 GHz,the antenna gain is over 22 dB,the antenna axial ratio is below 2 dB,and the aperture efficiency is more than 55%.
