Abstract: An FDMA (frequency division multiple access) based finite target oriented collisionless RFID (radio frequency identification) technology was proposed to solve the identification of multitarget. RFID systems based on the proposed technology have strong points such as collisionless, high speed, and high sensitivity, and are especially applicable to applications such as electronic article surveillance (EAS), infant school management, and so on. Technology of RFID tag design was studied and identification algorithm was introduced, and a set of simulative experiments were carried out. The results of simulative experiments prove the correctness of the proposed technology and techniques.

Key words: radio frequency identification (RFID), frequency division multiple access (FDMA), synthesizer, load modulation
