Determination of Manufacturing Tolerances of a Feed Horn using Uncertainty Quantification

This work presents the realization of a feed horn designed for a high-gain deployable K-Band reflectarray antenna-system placed on an 8U CubeSat platform that is to be used in an in-orbit technology demonstration. The main focus of this work is to estimate the tolerances necessary for the mechanical design, such that antenna performance has minimal degradation. Tolerances will be determined based on sensitivity analysis and uncertainty quantification. Measurement results are presented for comparison with the uncertainty quantification analysis.
