As there is still a demand for large SAR apertures for L and P-band, DLR and ESA decide in 2007 to start a collaborative study on Very Large Stable Membrane Antenna Architectures that is focussed on gossamer structures. The results of this study are shown in the paper. It contains a brief discussion on available conventional and gossamer antenna designs and introduces the elaborated design of our study. In addition, the sizing of the antenna parts is presented in extracts. An automated sizing approach involving routines in MATLAB and ANSYS is introduces that performs an autonomous sizing of such antenna structure for launch and operation loads within a time frame of about 8 minutes. Finally, this automatic sizing approach is used to do a parameter study and show the consequence of changed requirements or antenna membrane specification on the over all mass and mass spreading.
