In order to realize the miniaturization of quasi-Yagi antenna array, an antenna array with split-ring resonators (SRRs) based on two 7 units quasi-Yagi elements is designed in this paper. The radiation performance of the quasi-Yagi antenna array degrades significantly when array element spacing is reduced. After embedding SRRs on both sides of the miniaturized dielectric substrate surface, the S parameters and gain of array are significantly better than the array without SRRs, and the adjustable wave beam energy is also enhanced effectively. It indicates that the proposed antenna array with SRRs has good directional radiation performance under the miniaturize process at the operation frequency of 2.45 GHz, which could be widely applied in the fields of smart rail transportation and wireless power transfer.

使用裂环谐振器的高增益准八木天线阵列的小型化

为了实现准八木天线阵列的小型化，本文设计了基于两个7个单位的准八木天线的带裂环谐振器的天线阵列。当减少阵列元件的间距时，准八木天线阵列的辐射性能会大大降低。在小型化介电基板表面的两侧嵌入SRR后，阵列的S参数和增益明显优于无SRR的阵列，并且可调光束能量也得到了有效提高。结果表明，所提出的带SRR的天线阵列在2.45 GHz的工作频率下在小型化过程中具有良好的定向辐射性能，可广泛应用于智能轨道交通和无线电力传输领域。
