UAV Antenna

Antenna Experts manufactures unmanned aerial vehicles antennas for UAV Control Center, Remote Airborne Platform, Unmanned Ground Vehicles and Robots applications. These state-of-the-art antennas enable increased flight range and consistent radio frequency link performance over traditional airborne antennas. Additionally, the wideband antennas reduce the number of required apertures in an airframe, further reducing aerodynamic drag and logistics costs. The antennas that are used on unmanned vehicles are, in general, rugged, dipole or fiberglass collinear antennas with omni-directional coverage. Smaller and lighter weight Unmanned Aerial Vehicles (UAVs) are increasingly being used for more complex communications and intelligence applications. Directional helical antennas have been developed for special ground to air right hand circular (RCP)or left hand cirular (LCP) polarization applications.

Standard flange mounting arrangements or roof-top hole are available, however special mounting arrangements can be designed. Durable and robust, every effort is made to ensure the antenna meets the required specification to provide consistent signal coverage between the UAV Vehicles and UAV Control Station / Center.

The control centre antenna usually provides the higher gain part of the link and may be a medium to high gain omni - dipoles or collinears, medium to high gain directional helical antenna. Our Right Hand Circular Polarized (RHCP) Helical antennas are highly suitable for frequency hopping or spread spectrum telemetry system which operated in the 915-928 MHz range and a perfect choice for unmanned aircraft tracking system for UAV telemetry communication link at control center. Our UAH series directional helical antennas are supplied with two-axis steering system (tracking mechanism to rotate the UAVs antennas manually in azimuth and elevation plane). A less complex but compact multi-sector antenna array provides intermediate range coverage for communicating with a UAV. This type of arrangement can be used for quick deployment, tactical applications.
