Unmanned System Antennas

Unmanned Systems provide many operational functions including airborne surveillance, video transmission, border patrol and tactical support. In all cases, uninterrupted communication to the control centre is vital.

As the demand for Unmanned Systems increases, so does the need for a wider range of antennas, for payloads, data communications systems, command and control.

Competing performance- and cost-criteria are an important consideration when selecting an antenna. Chelton has a range of standard cost-effective, entry-level COTS antennas that are already used in extreme environments.

As frequencies increase from L-band to Ku-band, to provide wider bandwidths for higher data rates, the selection of the right antenna becomes critical, for optimising system performance, battery-life and transmission range. We provide a range of such antennas, including:

• High gain, collinear, vertically polarised omni antennas, installed in aerodynamic foil structures
• Common Data Link Ku-band omni antennas that have circular polarisation and up to 4dBiC gain
• Spiral antennas for direction finding
• Directional antennas for communication between airborne towed target and the towing aircraft
• Radar cross-section enhancement and radar detection antennas 
• Counter-drone antennas for reducing security threats. 

Pattern data is available for all of our antennas. We also have a range of Control Station antennas available. In order to achieve optimum results, we would need to provide antennas at both ends of an Unmanned System link.
