摘要：
A design of low sidelobe OAM planar annular array antenna is presented in this paper. The design is to achieve a low sidelobe level of multi-mode vortex beams by optimizing the annular array. The simulation results show that the low sidelobe design of multi-mode vortex beams simultaneously satisfies modes l =1, 2 and 3. The sidelobe levels of vortex beams with modes l =1, l =2 and l =3 are -29.1 dB, -29.9 dB and -24.6 dB, respectively, and the divergence angles are 3.9 degrees, 6.2 degrees and 8.3 degrees. The proposed annular array structure can be applied to the design of high-performance vortex beams for the future applications of high-speed and large-capacity wireless communications.
