Abstract

The technical assessment of large deployable reflector structures covering a diameter range from 4 to 50 m and RF frequencies up to Ka-Band is presented from the conceptual designs to the tests. Parametric FEM analysis tools of the concepts have been developed to study their static, modal and buckling behaviors. According to the selected conceptual design and acquired analysis results two complete breadboards with diameters of 1.6 m and 4 m based on a peripheral ring structure have been designed, manufactured and tested. Test results of both breadboards fulfilling the requirements on deployment repeatability and accuracy as well as scalability demonstrate the successful selection of a deployable ring design and large deployable antenna concept in whole.
