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。

Abstract: A variable polarization beam scanning antenna based on variable inclination continuous transverse stub antenna (VICTS) antenna and multi-layer all metal cross hole lens is proposed. By adjusting the rotation angles of the polarization layer, radiation layer, and antenna as a whole, free switching between linear polarization and left-hand (right-hand) circular polarization can be achieved, and two-dimensional beam scanning under different polarization outputs can be realized. A K-band antenna with a diameter of 150 mm was designed and simulated. The results show that the maximum gain of the circularly polarized radiation is 27.61 dB, the axial ratio is 1.05 dB, and the aperture efficiency is 58.7%; When the beam is scanned to 26°, the gain is 25.72 dB and the axial ratio is 2.58 dB. The maximum gain of linearly polarized radiation is 27.6 dB, and the aperture efficiency is 58.7%; When the beam is scanned to 26°, the gain is 25.82 dB. According to the metal breakdown threshold of 50 MV/m in vacuum, the power capacity of the VICTS antenna is 9.6 GW/m2, and the power capacity of the polarization layer exceeds 10 GW/m2. This variable polarization beam scanning antenna has the potential to be applied in the high-power microwave field. -
