The ENAC UAV team participates to a challenge named Fly2Corsica. The aim of this project is to link the French Riviera to the Corsica Island with a small electric UAV. To achieve a radio link between the French Riviera and Corsica (Fly2Corsica project), the ENAC UAV team plans to use the Iridium satellite service. To render this possible, a small antenna with good efficiency and pure circular polarization is required to optimize the link budget. We present an antenna that fulfils this requirements.
