The invention relates to the technical field of beam scanning holographic metasurface leaky-wave antennas, and particularly discloses an antenna unit with complementary split-ring resonators, an antenna and a beam scanning method.The antenna unit with the complementary split-ring resonators comprises a copper metal floor, a substrate integrated waveguide dielectric substrate, a microstrip line etched with a CSRR structure and a liquid crystal layer which are sequentially arranged from bottom to top; the substrate integrated waveguide dielectric substrate is used as a transmission structure; the substrate integrated waveguide dielectric substrate is formed by directly adding two rows of metal columns in the middle of the dielectric substrate in the microstrip line transmission structure; the CSRR structure in the microstrip line etched with the CSRR structure is etched in the middle part of the microstrip line in a penetrating manner, and the CSRR structure is composed of two metal groove rings with opposite o
