Abstract : The Buccaneer CubeSat will be fitted with a high frequency antenna made from spring steel measuring tape. The geometry of the antenna is described as open bowtie. In the microgravity of low Earth orbit there is a risk that the antenna will collapse or bend due to the extremely small loads. Worst case empirical analysis has shown that the antenna will remain deployed in low Earth orbit. This has been shown in the presence of worst case environmental loads due to aerodynamic drag (at 300km) and solar radiation pressure, combined with peak rotational accelerations. The high frequency open bowtie antenna will have a margin of safety of at least 54.8.
