This integrated reflective surface is too large in overall size, which greatly increases the packaging size of the antenna and is extremely inefficient when loading containers. In addition, this integrated reflective surface often leads to over-width and over-height during transportation, which significantly increases transportation costs and brings great inconvenience to transportation.

[0018] Refer to Figure 1 and Figure 2 According to an embodiment of the utility model, a reflective surface structure for a large-caliber microwave antenna includes: a parabolic reflector 1, a plurality of connecting plates 2 and a center ring 3. The parabolic reflector 1 includes a plurality of sub-lobes 11, and each sub-lobe 11 is fixedly connected by connecting plates 2. The connecting plates 2 are distributed at intervals along the connecting seams between adjacent sub-lobes 11, and the center ring 3 is fixedly arranged at the vertex of the parabolic reflector 1, and the symmetry axis of the parabolic reflector 1 passes through the center of the center ring 3.

[0019] Specifically, a positioning plate 4 is fixedly provided on the edge of each sub-lobe 11. Each positioning plate 4 is in the shape of a thin plate, and each positioning plate 4 extends on the wide surface and the narrow surface of the edge of the corresponding sub-lobe 11, and each positioning plate 4 is respectively located on one side close to the connecting seam between adjacent sub-lobes 11. The positioning plates 4 between adjacent sub-lobes 11 are fixedly connected by a connector 5. In this embodiment, the connector 5 includes but is not limited to fasteners such as screws and screws. Preferably, in this embodiment, the number of sub-lobes 11 is two. In other embodiments, in order to facilitate transportation, the number of sub-lobes 11 can also be three, four or more. Among them, each sub-lobe 11 is provided with an arc-shaped notch 12 on the curved surface close to the center ring 3. When each sub-lobe 11 is fixed, each arc-shaped notch 12 together forms a wire hole coaxial with the center ring 3. After the antenna is assembled, the fixed feed source is installed through the center ring 3 to power the parabolic reflector 1.
