Abstract

In this research, a novel high permittivity ceramic silicone composite substrate (HPCSCS) based antenna design is proposed for RF energy harvesting (RFEH). The HPCSCS is prepared using high-permittivity barium titanate (BaTiO₃) ceramic powder mixed with RTV silicone sealant (RTVSS) which possesses a high permittivity value of 11.9. Five different antenna designs were simulated in CST software and one design has been finalized based on design geometry, bandwidth, gain, and reflection coefficient. Moreover, the proposed antenna design is optimized with the addition of a coplanar waveguide. The designed antenna has a thickness of 0.06 mm and provides a wide operating band range from 0.7 GHz to 3 GHz. It provides a reflection coefficient of –32 dB and a positive gain of 1.84 dB at the operating frequency of 2.66 GHz demonstrating the excellent wide bandwidth of 885 MHz. A prototype of the antenna is fabricated and mounted on an HPCSCS for measurement through a vector network analyzer with a good match between the simulated and measured results. The rectenna system (antenna + rectifier) for RFEH has been developed and tested, which achieved a maximum rectifier conversion efficiency of 57 % at 0 dBm and produced a maximum output voltage of 1.35 V at 0 dBm.

用于能量收集的新型高介电常数陶瓷-硅树脂复合基底天线

本研究为射频能量收集（RFEH）提出了一种基于高导率陶瓷硅树脂复合基板（HPCSCS）的新型天线设计。HPCSCS 是用高介电常数钛酸钡（BaTiO3）陶瓷粉末与具有 11.9 高介电常数值的 RTV 硅酮密封剂（RTVSS）混合制备的。在 CST 软件中模拟了五种不同的天线设计，并根据设计几何形状、带宽、增益和反射系数最终确定了一种设计。此外，通过增加共面波导，优化了拟议的天线设计。设计的天线厚度为 0.06 毫米，工作频带范围从 0.7 千兆赫到 3 千兆赫。在工作频率为 2.66 GHz 时，它的反射系数为 -32 dB，正增益为 1.84 dB，显示出 885 MHz 的出色宽带宽。天线原型已制作完成，并安装在 HPCSCS 上，通过矢量网络分析仪进行测量，模拟结果与测量结果匹配良好。用于 RFEH 的整流天线系统（天线 + 整流器）已开发完成并进行了测试，在 0 dBm 时整流器转换效率最高达 57%，在 0 dBm 时输出电压最高达 1.35 V。
