16-element Conformal Sub-array Assembly and Its Impact on Performance

Due to the needs of miniature and conformal antenna arrays of SAR satellite, the research of curved multi-element active sub-arrays is carried out. Conformal RF sub-array is designed based on the LCP substrate, with a total of 5 LCP substrates and 4 connecting layers. The is assembled on the shell, and the multi-point glue coating method is designed to complete the bendable mounting of the LCP flexible array, with a bending angle of 10°. The result shows that conformal sample completed the typical simulation environment verification, and the electrical performance test results met the requirements of t curved LCP substrate he index.
