K-band high-power microwave variable-polarization antenna with variable inclination continuous transverse stub antenna

  • 摘要: 提出了一种基于可变倾角连续横向枝节(VICTS)天线和多层全金属十字开孔透镜的变极化波束扫描方案,通过调整极化层、辐射层以及天线整体的旋转角度,即可实现线极化和左(右)旋圆极化的自由切换,并可实现不同极化输出下的二维波束扫描。设计了一个K波段口径150 mm的天线模型,仿真得到天线圆极化辐射时的最大增益为27.61 dB,轴比为1.05 dB,口径效率为58.7%;波束扫描至26°时,增益为25.72 dB,轴比为2.58 dB。线极化辐射时的最大增益为27.63 dB,口径效率为58.7%;波束扫描至26°时,增益为25.82 dB。按真空中金属击穿阈值50 MV/m进行计算,VICTS天线的功率容量为9.6 GW/m2,极化层的功率容量超过10 GW/m2,该变极化波束扫描天线方案有应用于高功率微波领域的潜力。
