Vubiq Networks Completes Development of Millimeter Wave RFID Hyperimaging System

Vubiq Networks, Inc., the innovation leader in millimeter wave wireless broadband technology, products and solutions, announced that it has completed development of a hardware/software millimeter wave hyperimaging system.
The system incorporates Vubiq Networks’ patented high-bit density chipless radio frequency identification (RFID) technology using polarimetric synthetic aperture radar (POLSAR) in combination with proprietary software.

“Our breakthrough hyperimaging system is able to code and decode chipless RFID tags with an order of magnitude higher bit density as compared to existing solutions and competitive approaches,” said Mike Pettus, founder and CTO of Vubiq Networks. “Our system greatly improves performance while dramatically lowering costs due to our chipless RFID tags that use low electrical conductivity metals for the antenna elements, avoiding costly silver-based inks. We are able to achieve this breakthrough because we are not relying on spectral signature response, but instead relying on radar cross-section and antenna reradiation mechanisms.”

The system addresses the downfalls of traditional RFID solutions, especially today’s biggest barrier: the cost of the RFID tag. The company’s approach reduces tag costs to less than one cent per tag. With POLSAR as the technique for the RFID reader, tag and reader collisions are no longer an issue. By using the millimeter wave spectrum, reader performance increases and wireless disruption is minimized.

“Utilizing POLSAR hyperimaging as opposed to traditional RFID methods greatly expands the use cases by providing the ability to read multiple tags simultaneously, while also determining their three-dimensional location,” said Mr. Pettus.

The increased density and lower RFID tag costs are important developments for the marketplace, especially for emerging Internet of Things (IoT) applications. Vubiq Networks’ system achieves very high density chipless tag encoding through the use of innovative geometrical layout of patch antennas as the tiny tag elements. This provides for optimized element spacing, providing very high bit density for chipless RFID.

“As articulated by recent research from IBM*, hyperimaging is an exciting new technology space poised to dramatically change our world in many ways,” said Vubiq Networks CEO John Dilworth. “The current $11 billion RFID market is expected to explode to $40 billion by 2025**, so we see a bright future for our hyperimaging solution in RFID, as well as other areas.”

Next steps for the company include full product development, leveraging recently introduced single-chip millimeter wave radar solutions that incorporate 60 GHz radar and digital signal processing (DSP) in one device.

“The availability of new single-chip millimeter wave technologies that combine radar and DSP have significantly reduced the development time and costs to produce a high-volume, hyperimaging RFID reader,” said Mr. Pettus. “Having a DSP engine collocated with a millimeter wave radar front-end enables our patented artificial intelligence imaging algorithms to leverage our innovation in a single device.”
