TECHNOLOGY SUMMARY

Technology: Georgia Tech inventors have developed an antenna-less RFID tag which requires neither a tag antenna nor RF front-end circuits, thus leading to a system that does not have limitations on frequency at which tag can operate, can be reprogrammed to perform different functions such as emitting static bits or having dynamic communication, and overall leads to much simpler, smaller, and more reliable system. This technology is based on toggling electronic inverters that switch between two impedance states that can be read using any RF interrogator and a backscatter channel, which allows the information obtained by the RFID tag to be collected without the use of an antenna. This tag has the capability to operate at any frequency and can store a large number of static bits needed for asset identification and tracking or can be used for high data rate communication. Additionally, the technology enables easy programming of the tag such that existing hardware such as FPGAs can be programmed to behave as RFID tags.
