In this paper, the arc array for squint-less near-field focusing is used, theoretically analyzed, and verified. The arc array is designed to overcome the squint phenomenon in the near-field and transfers the maximum power at a focused distance. The implemented transmitter is composed of $16\times 1$ vivaldi antennas with a $0.7\lambda$ spacing and operates at a frequency of 5.8 GHz. In addition, the design method of the arc array is proposed, considering the focused distances. In the experiments, the bending degree of the arc array is ${4.14}^{\circ }$ when the focused distance is 0.5 m. At a fractional bandwidth of 27.5%, the focus position is shifted 32%. On the other hand, in the arc array, the focus position is not shifted. Experimental results from the implemented arc array show good agreement with the proposed theory.

本文采用了无斜视近场聚焦的弧形阵列，并进行了理论分析和验证。弧形阵列旨在克服近场中的斜视现象，并在聚焦距离传输最大功率。实施的发射机包括$16\times 1$ vivaldi 天线 $0.7\lambda$间隔并以 5.8 GHz 的频率运行。此外，还提出了考虑聚焦距离的圆弧阵列设计方法。在实验中，圆弧阵列的弯曲度为${4.14}^{\circ }$当聚焦距离为0.5 m时。在 27.5% 的部分带宽下，焦点位置移动了 32%。另一方面，在圆弧阵列中，焦点位置不偏移。实现的弧形阵列的实验结果与所提出的理论非常吻合。
