Daniel Belo, Felisberto Pereira, Marina Jordão and Ricardo Correia, researchers from IT in Aveiro, under the coordination of Nuno Borges de Carvalho, were the winning team of the TC:24 (RFID Technologies) - Backscatter Radio, held within the International Microwave Simposium (IMS) 2018 Student Design Competitions, that took place last June 10 – 15 in Philadelphia, USA.
This competition required participants to design, fabricate and test a backscatter radio, which is a fundamental block of Ultra-High-Frequency (UHF) Radio Frequency IDentification (RFID) transponders. In an RFID system the reader transmits a continuous wave signal, while the transponder reflects the signal and introduces a modulation, so as to convey its information. The prototype under test should consist of a binary backscatter modulator (i.e., based on binary amplitude shift keying, BASK, or binary shift keying, BPSK) that operates on 915 MHz.
The winning team from IT received a $1000 check and the possibility to publish an article on IEEE Microwave Magazine about the work developed.
Organized by the IEEE MTT, the International Microwave Symposium (IMS) is the premier annual international meeting for technologists involved in all aspects of microwave theory and practice.
