This paper presents a wearable rectenna array fabricated using Cordura textile material for harvesting low-power radio frequency (RF) energy. The dielectric properties of the textile were thoroughly investigated for circuit and antenna design. The rectenna element comprises a linearly polarized patch antenna and a single-stage full-wave Greinacher rectifier. The proposed stack topology helps reduce the size of the elements in the rectenna array. An RF choke is added to the array to prevent impedance mismatch due to changes in load impedance, and a foam with a shielding ground is inserted between the rectifier circuit and the human body to eliminate the body-proximity effect. A maximum output voltage of 1.05 V is achieved when the 2 × 2 rectenna array attached to a human body and 150 cm from the indoor Wi-Fi access point whose output power is 20 dBm and the antenna gain is 5 dBi.

在 Cordura 织物上实现的可穿戴纺织整流天线阵列的设计和建模，用于无电池应用

本文介绍了一种使用 Cordura 纺织材料制造的可穿戴整流天线阵列，用于收集低功率射频 (RF) 能量。为了电路和天线设计，对纺织品的介电特性进行了彻底的研究。整流天线元件包括一个线性极化贴片天线和一个单级全波 Greinacher 整流器。建议的堆栈拓扑有助于减小整流天线阵列中元件的尺寸。阵列中添加了射频扼流圈以防止由于负载阻抗变化导致阻抗不匹配，并在整流电路和人体之间插入带有屏蔽接地的泡沫以消除人体接近效应。最大输出电压为 1。
