“…Referring to the second scheme improving the RSE in Ref. [ 45 ], the antenna RSE can be improved by simply rotating the regular panel. If combined with the deviation-angle panel, performing the same scheme can further improve the RSE, which is elaborated as follows.…”

“…In order to further explore the RSE performance of the proposed antenna, the RSE obtained by utilizing the third RSE-improving scheme in Ref. [ 45 ] is reported in Table 5 . In this scheme, the panel pose is obtained by conducting an optimization algorithm; hence, its RSE is higher than that in Table 4 theoretically.…”

“…In Table 5 , in combination with the third pose adjustment strategy in Ref. [ 45 ], the RSE is improved further, with a minimum of 11.76% for the improved sunflower and a maximum of 52.87% for the Dornier FIRST. It must be emphasized that, compared with the RSE adopting the regular panel and third pose adjustment strategy (i.e.,

in Table 5 ), the RSE adopting the deviation-angle panel in Table 4 can be higher if

“…Therefore, the above approach is inadvisable for realizing high stowing efficiency. The second approach improving the stowing efficiency is conducted through the conjunction of the pose adjustment and bisection method [ 45 ]. This approach improves the stowing efficiency to some extent without increasing the petals, and the efficiency can be further improved if adopting what is called the deviation-angle panel proposed in this study.…”

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 electromagnetic (EM) performances in terms of gain, resolution and sensitivity. After conducting systematic feature analysis with respect to several typical RRSAs, we propose a novel type of RRSA to solve the aforementioned problems. Inspired by the pose adjustment process for a higher stowing efficiency of traditional RRSAs, we also propose a new segmentation scheme of a reflective surface consisting of a deviation-angle panel that facilitates a higher stowing efficiency. Based on this scheme, its corresponding folded configuration is implemented by combining Euler’s rotation theorem and the idea of parameter identification. In addition, we also compare the stowing efficiency of different schemes to verify the high stowing efficiency of the configuration. Finally, we perform mechanism/structure design and deployment dynamics to demonstrate that the antenna can be successfully deployed and exhibits excellent deployment quality. The results suggest that the proposed antenna possesses higher stowing efficiency than that of the same kind, with a stable deployment and interference-free process.
