摘要

The limits of variation of the rms error of the antenna surface from the paraboloid of revolution are defined in this study. The analysis of obtained results allows us to draw a conclusion about the necessary elastic parameters of the antenna membrane. The minimum rms deviation is obtained in the case when the material of the antenna membrane features well-defined anisotropy of the elastic properties. The warp yarns of the antenna membrane should be arranged in the circumferential direction, whereas weft yarns should be arranged in the radial direction. The obtained results can be used for the analysis of the deviations of the membrane surface at the stage of the preliminary design of umbrella-type antennas.
