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

  • 摘要: 該文針對(duì)超高頻射頻識(shí)別(UHF RFID)標(biāo)簽自身參數(shù)和標(biāo)簽間互相耦合對(duì)標(biāo)簽天線增益的影響，推導(dǎo)了相應(yīng)的理論模型。首先從輻射場(chǎng)的角度將標(biāo)簽等效為帶集總負(fù)載的對(duì)稱振子天線，然后基于對(duì)稱振子天線陣列的理論建立了小間隔雙標(biāo)簽天線增益的簡(jiǎn)化模型，并對(duì)密集多標(biāo)簽應(yīng)用場(chǎng)合進(jìn)行了簡(jiǎn)單拓展，仿真研究驗(yàn)證了所建模型的有效性。最后對(duì)增益的方向性和輻射效率進(jìn)行了研究，研究結(jié)果對(duì)密集標(biāo)簽的性能研究具有一定的指導(dǎo)意義。
    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.
