Deployable helical antennas for cubesats

Abstract

This paper explores the behavior of a self-deploying helical pantograph antenna for CubeSats.The helical pantograph concept is described along with concepts for attachment to the satellite bus.Finite element folding simulations of a pantograph consisting of eight helices are presented and compared to compaction force experiments done on a prototype antenna.Reflection coefficient tests are also presented, demonstrating the operating frequency range of the prototype antenna.The helical pantograph is shown to be a promising alternative to current small satellite antenna solutions.
