Abstract :
Development of a low-cost active radio frequency identification (RFID) tag that works at 2.4 GHz in the ISM frequency band is presented. The tag is comprised of an annular ring slot antenna, feed and matching network, a parallel Schottky diode modulator and a microcontroller with an in-built oscillator. The tag is powered by a 3V pill-box battery and uses amplitude shift keying (ASK) modulation to communicate with the reader. Results presented include the performance of the slot antenna, feed network, associated software and the tag´s identity as received by a Hyper-X reader
