Abstract
In this paper, we propose a novel transparent microwave thin film coating technique and discuss its application in planar dual-band antennas (0.9/5.55 GHz). We developed a new process for activating the nano-alignment thin film from high to low resistivity (from 1.96 to 1.29 × 10−4 Ω cm) and from partial to full transparency (from 55 to 83% transmittance) within 150 s. The platform of the activation process comprises a periodic electrode, an optical microscope, and an alternating current signal generator. The periodic electrode can effectively rearrange the nano-alignment thin film into an ordered arrangement, which enhances the properties of the thin film in the microwave frequency range. A high-transparency and low-resistivity dual-band antenna is designed and fabricated using the proposed microwave thin film coating technique. The dual-band antenna has operating bandwidths of 740–960 and 5030–7030 MHz and potential applications in transparent electronics such as wearable devices and intelligent cars.

一种应用于双频天线的新型透明微波薄膜涂层技术
抽象的
在本文中,我们提出了一种新颖的透明微波薄膜涂层技术,并讨论了其在平面双频天线(0.9 / 5.55 GHz)中的应用。我们开发了一种将纳米取向薄膜从高电阻率激活到低电阻率的新工艺(从1.96到1.29×10 -4 Ωcm),并在150 s内从部分透明到完全透明(透射率从55%到83%)。激活过程的平台包括一个周期性电极,一个光学显微镜和一个交流信号发生器。所述周期性电极可以有效地将纳米取向薄膜重排为有序排列,这增强了在微波频率范围内的薄膜的性能。利用所提出的微波薄膜涂覆技术设计并制造了一种高透明,低电阻率的双频天线。双频天线的工作带宽为740–960和5030–7030 MHz,并潜在地应用于可穿戴设备和智能汽车等透明电子产品。
