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

  • 摘要: 該文針對超高頻射頻識別(UHF RFID)標簽自身參數(shù)和標簽間互相耦合對標簽天線增益的影響,推導了相應的理論模型。首先從輻射場的角度將標簽等效為帶集總負載的對稱振子天線,然后基于對稱振子天線陣列的理論建立了小間隔雙標簽天線增益的簡化模型,并對密集多標簽應用場合進行了簡單拓展,仿真研究驗證了所建模型的有效性。最后對增益的方向性和輻射效率進行了研究,研究結果對密集標簽的性能研究具有一定的指導意義。
