1. A pillar-shaped luneberg lens antenna, comprising two metal plates parallel to each other and a pillar-shaped luneberg lens disposed between the two metal plates, wherein
the pillar-shaped luneberg lens comprises a main layer and a compensation layer, and the compensation layer is configured to compensate for equivalent dielectric constants of the main layer of the pillar-shaped luneberg lens in a TEM mode and/or a TE10 mode, so that a distribution of the equivalent dielectric constants of the pillar-shaped luneberg lens in the TEM mode and the TE10 mode is consistent with a distribution of preset dielectric constants;
when the distribution of the equivalent dielectric constants of the pillar-shaped luneberg lens in the TEM mode is consistent with the distribution of the preset dielectric constants, the pillar-shaped luneberg lens antenna has a polarization in a direction orthogonal to the two metal plates; and
when the distribution of the equivalent dielectric constants of the pillar-shaped luneberg lens in the TE10 mode is consistent with the distribution of the preset dielectric constants, the pillar-shaped luneberg lens antenna has a polarization in a direction parallel to the two metal plates.
