High Bandwidth Microstrip Patch Antenna

The US Navy seeks to commercialize an easy-to-implement microstrip patch antenna design that provides significantly higher bandwidth in retrofit or new constructs while maintaining device footprint and other important performance characteristics.

Navy invention uses a highly anisotropic superstrate to produce a GPS patch antenna with a 20 – 25% bandwidth; invention is applicable for new or existing patch antennas and is scalable to other frequencies
The Technology: 

The Naval Undersea Warfare Center Division Newport (NUWCDIVNPT) has developed and tested a microstrip patch antenna that increased the bandwidth of the prototyped GPS antenna from a typical 2-5% to 20-25%; the upper limit for other frequencies has not been determined.  The key to this innovation is the use of a highly anisotropic superstrate layer that can be placed over an existing patch antenna as a retrofit or incorporated into new systems.  Proper design of the superstrate layer and the correct orientation of its polarization layer enable broader bandwidth capabilities for a given antenna.  The results include the ability to work over a broader range of frequencies and increases in potential channel bandwidth from an existing antenna without increasing the footprint of the device.

  • Wide Bandwidth: Substantial bandwidth improvement enables diverse, multiple capabilities from a single antenna (e.g. satellite telephone and GPS) and higher data transfer rates
  • Easy to Upgrade Legacy Devices:  Robust, fault tolerant design offers substantial potential to easily retrofit and greatly improve performance and capabilities of existing patch antennas without altering the device footprint
  • Broadly Applicable:  Designed to retrofit an L-Band antenna; applicable to a wide swatch of frequencies and new systems
  • Excellent Performance: Other performance characteristics important to antennas are not compromised
The Opportunity: 
  • US Patent Application 14/040,810 available for license
  • Potential for collaboration with NUWCDIVNPT researcher
