摘要

本文提出了一种柔性半透明天线，其阻抗带宽为110 MHz (2.45 GHz至2.56 GHz)的ISM频段，该频段覆盖了全球最流行的Wi-Fi应用(2.4 GHz)。采用激光直写的方法，在Au溅射PET薄膜上制备了一个简单的偶极子形状矩形环形天线。天线的中心部分故意保持空和透明，以便与用于微波无线充电的平面电容器或将来将该天线与太阳能电池集成在一起。天线的紧凑，微型和灵活性适合于轻松集成在任何智能设备或服装中进行无线充电，以实现自供电传感器。利用回波损耗(S11)参数分析对贴片天线的性能进行了评价。实测的反射系数和模拟的电流随辐射方向图的分布表明，该天线适合于Wi-Fi应用。

Flexible and Semi-Transparent Antenna for ISM Band Fabricated by Direct Laser Writing

In this paper, a flexible and semi-transparent antenna is proposed having impedance bandwidth of 110 MHz (from 2.45 GHz to 2.56 GHz) of ISM band which covers the most popular (2.4 GHz) for Wi-Fi application all over the world. A simple dipole shape rectangular ring antenna with two extended edge on the opposite sides was prepared by laser direct writing on an Au sputtered PET film. The center part of the antenna was kept empty and transparent intentionally to incorporate with either a planar capacitor for microwave wireless charging or to integrate this antenna with a solar cell in future. The compact, miniature and flexibility of the antenna are suitable for easy integration in any smart devices or clothing for wireless charging to implement self-powered sensors. The performance of the patch antenna is evaluated using return loss (S11) parameter analysis. A measured reflection coefficient and simulated current distribution along with radiation pattern demonstrate that the fabricated antenna is suitable for Wi-Fi application.
