Performance Degradation of RFID System due to the Distortion in RFID Tag Antenna

• In some of the radio-frequency identification (RFID) applications, RFID tag antennas will be printed onto flexible substrates. Sticked onto different surfaces, geometric distortion of the tag antenna, such as bending of the tag, could occur due to antenna substrate flexibility. In the present paper performance degradation due to such distortion of an RFID system, using the common half-wave dipole antennas usually used in tags, is simulated. It is shown that degradation of RFID system performance in terms of operating range due to such distortion is significant and that antenna structures less sensitive for this deformation should be considered for RFID systems where this kind of effect may occur.
