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.
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
