Study on Gain Characteristics of Dual Ultra-high-frequency Radio Frequency Identification Tag Antennas with Small Interval

摘要

摘要: 该文针对超高频射频识别(UHF RFID)标签自身参数和标签间互相耦合对标签天线增益的影响，推导了相应的理论模型。首先从辐射场的角度将标签等效为带集总负载的对称振子天线，然后基于对称振子天线阵列的理论建立了小间隔双标签天线增益的简化模型，并对密集多标签应用场合进行了简单拓展，仿真研究验证了所建模型的有效性。最后对增益的方向性和辐射效率进行了研究，研究结果对密集标签的性能研究具有一定的指导意义。

Abstract: 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.
