Abstract

This work presents a two-axis beamsteering system designed for WLAN millimeter-wave frequencies. The system comprises a wideband Butler matrix and series-fed arrays. The Butler matrix, implemented with microstrip lines, features a wideband crossover with low phase imbalance, enabling four discrete beamsteering directions on the radiation H-plane. The series-fed arrays enable frequency-dependent beamsteering on the E-plane. The entire system was fabricated on a nanoporous alumina substrate using metallic-nanowire-membrane technology. Measurement results indicate an impedance bandwidth of 17.71%, which accommodates typical requirements for 60 GHz WLAN applications. Additionally, beamsteering in the desired directions was achieved. The presented Butler matrix structure stands out as one of the most compact found in the reviewed literature. The produced device successfully balances wideband behavior, compactness, and fabrication simplicity.

使用宽带巴特勒矩阵和串联馈电阵列进行双轴波束转向，用于在金属纳米线膜平台上制造毫米波频率

本作品介绍了一种专为无线局域网毫米波频率设计的双轴波束转向系统。该系统由宽带巴特勒矩阵和串联馈电阵列组成。巴特勒矩阵使用微带线实现，具有低相位不平衡的宽带交叉功能，可在辐射 H 平面上实现四个离散的波束转向方向。串联馈电阵列可在 E 平面上实现随频率变化的波束转向。整个系统是利用金属纳米线膜技术在纳米多孔氧化铝基板上制造的。测量结果表明，阻抗带宽为 17.71%，符合 60 GHz WLAN 应用的典型要求。此外，还实现了所需方向的波束转向。所介绍的巴特勒矩阵结构是目前所见文献中最紧凑的结构之一。该器件成功地兼顾了宽带性能、紧凑性和制造简易性。
