[0055] see Figure 6-Figure 12 , this embodiment provides a phase compensation method for a magnetoelectric dipole broadband polarization twisted lens antenna. In this embodiment, in order to realize the conversion from linear polarization to circular polarization, the center feed of transmitting antenna 15 The probe of the structure 19 can be rotated at intervals of 90°, thereby generating circularly polarized transmitting beams, while the receiving antenna 16 and the tapered dielectric coating layer 1 cooperate with each other to achieve the effect of phase compensation.

[0056] Specifically, in this embodiment, this patent proposes and compares and analyzes four phase compensation schemes, which are 1-bit, 2-bit, super 2-bit and full-phase adjustment phase compensation schemes, wherein, in 1-bit phase compensation The above-mentioned tapered dielectric coating layer 1 is not used in the scheme, and the other three phase compensation schemes use the rotation of the feeding pro
