    摘要:

    基于微带天线的基本理论,设计了一种适合用作声表面波射频识别系统的阅读器天线。首先,计算分析了该微带天线的基本尺寸,并利用ADS软件设计了有阻抗变换器功能的微带线,使天线输入阻抗达到50 Ω;然后,利用HFSS软件进行了微带天线的建模仿真和参数优化,确定了天线的最终尺寸;实际制作天线并对其进行了测试,测试结果和仿真数据吻合较好,在谐振频率处驻波比小于2;最后,结合阅读器对标签进行了无线测试,验证了阅读器天线的可用性。

    Abstract:

    A reader antenna suitable for SAW radio frequency identification system was designed based on the basic theory of the microstrip antenna. Firstly, the basic size of the microstrip antenna was analyzed and calculated. In addition, a microstrip line with impedance conversion function was designed by using the ADS software, the input impedance of antenna was up to 50 Ω. Then the modeling and parameters optimization of the microstrip antenna were carried out by using the HFSS software, thus the final dimension of the microstrip antenna was determined. The antenna was manufactured and tested. The test results were in good agreement with the simulated ones, and the voltage standing wave ratio of the antenna was less than 2 at the resonant frequency. Finally the tag was wirelessly tested by combining with the reader, verifying the practicability of the reader antenna.
