The US Navy has designed a conformal mobile antenna with significant gain (6-10 dB) and cross-polarization signal rejection (30 dB) capabilities for use in SATCOM and other VHF/UHF applications.

The Technology: 

The US Naval Surface Warfare Center, Crane Division (NSWC Crane) has designed and tested a patent-pending conformal antenna for mobile satellite communication (SATCOM) and other applications.  The antenna provides significant gain and cross-polarization signal isolation advantages compared to half-wave dipole antennas.  The antenna performs best at the most critical orientation—directly overhead in an antenna radiation pattern where overall signal strength and the potential for unwanted interference is the largest and most likely to occur during SATCOM events—and maintains high performance over wide angles of incidence encountered by in the field by mobile craft and vehicles.

The Navy antenna was designed for low-profile, conformal form factors, including spray-on applications.  The design is amendable to a variety of materials and maintains standard 50 ohm feed point impedance for use with standard radio equipment.  The improved gain and signal isolation benefits are created through an innovative layout that feeds two delta loops in parallel and in phase.  The delta loops are rotated 90 degrees orthogonally and translated linearly with respect to the axis of rotation.

Benefits: 
  • High Gain:  Average 3-4 dB gain improvement for signals directly
    overhead compared to typical SATCOM antennas; maintains high
    performance over the range of incidence angles required for rapid,
    mobile communication
  • Excellent Cross-Polarization Rejection:  Innovative design achieves 30 dB isolation as measured at US Navy communication test facilities
  • Highly Adaptable: 
    Extremely low-profile for spray-on and other conformal implementations
    using standard industry components for circularly polarized VHF/UHF
    applications
The Opportunity: 
  • One pending US patent application is available for license
  • Potential for collaboration with NSWC Crane researchers to further improve the technology, adapt it to other applications, and pursue joint opportunities
