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.关键词
