摘要：

Parameters of the Ultra-High-Frequency Radio Frequency IDentification (UHF RFID) tags and the mutual coupling effect have great impact on antenna gain, and a corresponding theoretical model is developed. Firstly, from the perspective of the radiation field, the tag is equivalent to dipole antenna with lumped load. Then based on the theory of dipole array, a simplified gain model of dual tag antennas with small interval is derived, and application of multiple tags is expanded simply. The simulation results show that the model is effective. Finally, the directivity and radiation efficiency are studied. The results provide a theoretical guidance for the research of intensive tags performance. ©, 2015, Science Press. All right reserved.
