Rigid-reflector spaceborne antennas (RRSAs) are well-suited for high-frequency application scenarios due to their high surface accuracy. However, the low stowing efficiency of RRSAs limits the aperture diameters and further deteriorates the electroma

Space antennas with high gain and high directivity are in great demand for future communication and observation applications. Deployable cable-mesh reflector antennas are required to be tensioned in a self-equilibrated state through form-finding desi

Owing to the rapid developments in space technology, there has been a substantial increase in the demand for large-diameter and low-mass space-borne deployable antennas with high geometric stability. To meet this demand, this paper presents a novel s

In extreme space environments with alternating and uneven temperature variations, the surface accuracy of cable-net antennas deteriorates significantly, thereby inducing a periodic failure or a significant deviation in the electrical performance. Thi

An optimization method for the winding strategy of the driving cable is proposed based on a dynamic analysis of the AstroMesh antenna deployment. First, considering the effects of the cable net and friction, the driving force for deployment is deduce

The wire mesh is a key component of a cable–mesh deployable antenna; it is laid on the cable net to reflect electromagnetic waves. The knitting form, mesh size, and wire mesh ductility directly aff...

Traditional methods for designing a mesh reflector usually treat the rim truss as rigid. Due to large aperture, light weight and high accuracy requirements on spaceborne reflectors, the rim truss deformation is indeed not negligible. In order to desi
