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
- Potential for collaboration with NUWCDIVNPT researcher
