Example Embodiment
[0046] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention, but not to limit the present invention.
[0047] In view of the large overall volume and heavy weight of the existing technology antenna, it cannot be directly used as a spaceborne antenna; the shape accuracy and stability are poor. The designed structure of the invention is lightweight and reliable, and the parabolic cylindrical deployable antenna that meets the requirements of a certain shape and surface accuracy has important practical significance. On the basis of a mesh expandable antenna, the present invention proposes a cable net parabolic cylindrical expandable antenna device based on a scissor truss mechanism.
