Abstract

A metallic 3-D-printed reflectarray (RA) based on a novel coaxial unit cell (UC) is presented herein for mm-wave applications. A full phase tuning range is achieved by varying the UC depth. The UC design allows for incident wave polarization independence and operability over a wide range of frequencies. A $16\times 16$ RA utilizing the proposed UC is designed, simulated, fabricated, and characterized. Furthermore, the RA performance is benchmarked against a conventional RA with printed square microstrip patch UC. The simulated and measured radiation patterns of both RAs in the E-plane demonstrate the achievement of accurate beam steering at the desired angle. The proposed RA is shown to have a higher gain (25.8 dBi) and efficiency (54%) compared to the conventional RA constructed using printed circuit technology. The proposed RA design is deemed promising for applications with stringent environmental conditions.
具有同轴单元格的3d打印毫米波反射阵列
本文提出了一种基于新型同轴单元电池(UC)的金属三维打印反射天线(RA),用于毫米波应用。通过改变UC深度实现全相位调谐范围。UC设计允许入射波偏振无关性和在宽频率范围内的可操作性。利用所提出的UC设计,模拟,制造和表征了A $16\ × 16$ RA。此外,RA的性能与传统的带有印刷方形微带贴片UC的RA进行了基准测试。模拟和测量的两种ra在e平面上的辐射图表明,在所需的角度上实现了精确的波束转向。与使用印刷电路技术构建的传统RA相比,所提出的RA具有更高的增益(25.8 dBi)和效率(54%)。建议的RA设计被认为有希望在严格的环境条件下应用。
