The Technology

Omni-ID: A leader in innovation

Omni-ID's RFID tags are developed around existing patented technologies which enable the company to meet market and customer needs for longer read distances, improved performance and reliability, global functionality and interoperability with other RFID hardware and software.

Patented Plasmonic Structure

Omni-ID's technology represents a fundamentally new approach to RFID tag design. Omni-ID RFID tags use a two-component system that optimizes the use of plasmonics and near field antenna design (coupling structure). Omni-Id's design differs dramatically from the traditional RFID tag design of an antenna with a foam spacer to reduce the effects of interfering backing materials.

The patented plasmonic structure - a dielectric core sandwiched between two layers - captures incoming RF waves and isolates them from surrounding materials, preventing them from "seeing" what is beneath the tag. As a result, the tag works reliably no matter what material it is placed on, without the need for a spacer.

The near field coupling structure in Omni-ID tags uses a coupler and chip attach, custom designed by Omni-ID, as opposed to a typical tag structure with a chip attached to an antenna. This coupling structure increases the flexibility in design and facilitates unique performance while improving the capacity for solid state quality.

Optimization of Omni-ID's core technology has yielded industry-leading product capabilities, including Excellent read signal on, off, and near metals and liquids Longer read ranges than previously available on a passive tag Extremely rugged and durable tag construction A broadband operating range which enables global functionality. Global Omni-ID tags are optimized across 860-960MHz, providing strong functionality across all geographic regions in accordance with EPC Gen2 Protocol.

Origins of the Plasmonic Structure

Omni-ID's plasmonic substrate was discovered using biomimetics, the application of designs and processes found in nature. Scientists using this unique methodology observed how the wing structure of the Blue Morpho butterfly reflects light, and applied that concept to RF technology. The plasmonic structure was developed based on the butterfly's wing structure - reflecting RF energy instead of light.
