A Light and Compact Circular Polarized Antenna for First-Person-View (FPV) Drones

This work presents the design of a compact, omnidirectional, and circular polarized antenna for first-person-view (FPV) drones. An FPV drone is an aircraft used in sporting activities, where the pilot, equipped with a visor, controls the drone’s activities. Due to the high velocity of FPV and the required low reaction time, the radio connection must be safe and accurate. An omnidirectional antenna with circular polarization, high gain, low weight, and good mechanical robustness is mandatory for FPV design. The proposed antenna is designed and fabricated on a ceramic substrate operating at 5.8 GHz. The prototypes tested ensure that the proposed design is a potential candidate for FPV applications. A set of antenna prototypes has been designed, fabricated, and assessed numerically and experimentally, demonstrating the capabilities and potential of the proposed antenna design.
