Abstract: A method for producing a satellite to facilitate the inclusion of one or more reflector antennas on a surface of the satellite is disclosed. A reusable generic configuration is determined in advance separately from the satellite mission. The generic configuration generally features the following parameters for each reflector: diameter, focal distance, offset distance of the reflector in the deployed position, position of the deployment device, position of the radiofrequency source. The generic configuration is determined such that an antenna points by default towards the centre of the earth when its reflector is in a deployed position. A specific configuration step then consists of defining a limited number of specific parameters depending on the satellite mission. The specific configuration is rendered possible in particular by controlling the deployment device, i.e., by changing the direction in which the antenna points, once the reflector has been deployed.

Abstract: Systems, devices, and methods for providing deployable and collapsible Quadrifilar Helical Antennas (QHA) on small satellites to improve communications in low earth orbit satellites. Monopole antennas are very popular for use on small satellites, generally because they are relatively easy to attach. By using circularly polarized antennas for the spacecraft and the ground station, polarization losses are virtually eliminated. The QHA can be designed to have a wide range of circularly polarized antenna patterns. Low power transmitters are employed on the small satellite to be consistent with the available energy. The communication link budgets are dependent on good radiation pattern characteristics for the small satellite downlink where higher data rates are required. Quadrifilar Helical Antennas can be collapsed and stowed inside a module to mount inside typical cubes known as 1U through 27U size small satellites. After launch from the rocket, the QHA can be deployed to its stored memory shape.
