在射频识别系统的应用中往往需要较长的工作距离,及不同的识别区域,为了达到这个目的,我们设计了两种天线阵。本文对它们进行了理论分析,发现这两种天线阵有互补的近场特性,最后从实验中证明了理论计算的正确性。这两种天线阵在实际应用中都是很重要的。 In the application of radio frequency identification system often requires longer working distance, and different identification area, in order to achieve this goal, we designed two antenna arrays. In this paper, they are theoretically analyzed and found that the two antenna arrays have complementary near-field characteristics. Finally, the correctness of the theoretical calculation is proved from experiments. Both antenna arrays are very important in practical application.
