2019 IEEE International Conference on RFID (RFID)

Year: 2019 | Conference Paper | Publisher: IEEE

Abstract: The measurements reported in this work demonstrate the ability to extend the localization range of low-powered RFID tags to distances usually not achievable with conventional RFID technology. The ranging technique is performed through the Frequency Domain Phase Difference Of Arrival (FD-PDOA) method on a 5.8 GHz Tunneling Tag, both in a multipath-rich indoor environment and outdoor, at distances up to 15 meters from the reader. Range estimation errors as low as 1.95% were observed, moreover, an EIRP of only 10.5 dBm, a biasing power for the Tunneling Tag of only 21.32 μW (80 mV), and a tag antenna gain of 1 dBi suggest the potential of power-stingy Tunneling Tags to be used in low-powered RFID localization applications for very long-range scenarios.

Two ORS undergraduate researchers have won 1st and 3rd place student research presentation awards as part of the TECHCON 2019 conference held in Austin, TX last week.  Daniel Yang won 1st place for presenting his research poster on Printable RF Circuits as part of the Tentzeris ORS group, led by PhD student Aline Eid. Jesse Jiang won 3rd place for presenting his research poster on 24 GHz RFID Tags as part of the Durgin ORS group, led by PhD student Mohammad Alhassoun.

Georgia Tech sent 7 undergraduates to present at TECHCON, which draws top researchers, scientists, and a large field of students from across the United States to present cutting-edge research in the field of semiconductor electronics.
