摘要

在 5G 和即将到来的 6G 通信领域,毫米波频段提供了更大的带宽。然而,由于其传播特性,对齐天线成为一个具有挑战性的问题,尤其是在工业和车载网络应用的节点侧。角度扫描天线可显著提高通信可靠性,或为空间复用提供新的可能性。以往的研究主要集中于频率扫描天线,其特点是低增益的单个单元或昂贵的数字阵列。因此,既有成本效益又有高增益的解决方案一直很稀缺。本研究提出了一种通过延长元件之间的馈电线来实现频率扫描的方法。基于这种方法,开发出了毫米波高增益串行馈电频率扫描天线。该天线工作在 60-64 GHz 毫米波 ISM(工业、科学和医疗)频段内,能够在 E 平面上执行 10 ∘ $^\circ$ 扫描。此外,该天线的宽度小于半个波长,可将多个天线组装成一个多输入多输出阵列。

A series-fed frequency scanning antenna for millimeter wave wireless communication

In the realms of 5G and the upcoming 6G communications, the millimeter-wave bands offer substantially greater bandwidth. However, due to their propagation characteristics, aligning antennas becomes a challenging issue, particularly at the node side in industrial and vehicular network applications. Angle-scanning antennas can significantly enhance communication reliability or provide new possibilities for spatial multiplexing. Previous studies have predominantly concentrated on frequency-scanning antennas characterized by either low-gain individual units or expensive digital arrays. Consequently, there has been a scarcity of solutions that are both cost-effective and high-gain. In this study, a method is proposed for achieving frequency scanning by extending the feed lines between elements. Based on this approach, a millimeter-wave high-gain serial-feed frequency-scanning antenna is developed. This antenna operates within the 60–64 GHz millimeter-wave ISM (Industrial, Scientific, and Medical) band and is capable of performing a 10 $^\circ$ scan in the E-plane. Moreover, the antenna maintains a width of less than half a wavelength, allowing for the assembly of multiple antennas into a MIMO array.
