Abstract

This paper presents a compact stacked RF energy harvester operating in the WiFi band with multi-condition adaptive energy management circuits (MCA-EMCs). The harvester is divided into antennas, impedance matching networks, rectifiers, and MCA-EMCs. The antenna is based on a polytetrafluoroethylene (PTFE) substrate using the microstrip antenna structure and a ring slot in the ground plane to reduce the antenna area by 13.7%. The rectifier, impedance matching network, and MCA-EMC are made on a single FR4 substrate. The rectifier has a maximum conversion efficiency of 33.8% at 5 dBm input. The MCA-EMC has two operating modes to adapt to multiple operating conditions, in which Mode 1 outputs 1.5 V and has a higher energy conversion efficiency of up to 93.56%, and Mode 2 supports a minimum starting input voltage of 0.33 V and multiple output voltages of 2.85-2.45 V and 1.5 V. The proposed RF energy harvester is integrated by multiple-layer stacking with a total size of 53 mm × 43.5 mm × 5.9 mm. The test results show that the proposed RF energy harvester can drive a wall clock (30 cm in diameter) at 10 cm distance and a hygrometer at 122 cm distance with a home router as the transmitting source.

摘要

本文介绍了一种紧凑的堆叠式射频能量采集器，其在WiFi频段工作，并配备多条件自适应能量管理电路（MCA - EMC）。该采集器分为天线、阻抗匹配网络、整流器和MCA - EMC。天线基于聚四氟乙烯（PTFE）基板，采用微带天线结构，并在接地平面上设置环形缝隙，以使天线面积减小13.7%。整流器、阻抗匹配网络和MCA - EMC均制作在单个FR4基板上。该整流器在5 dBm输入时的最大转换效率为33.8%。MCA - EMC有两种工作模式以适应多种工作条件，其中模式1输出1.5 V，能量转换效率高达93.56%，模式2支持0.33 V的最小启动输入电压以及2.85 - 2.45 V和1.5 V的多个输出电压。所提出的射频能量采集器通过多层堆叠集成，总尺寸为53 mm×43.5 mm×5.9 mm。测试结果表明，以家用路由器作为发射源时，所提出的射频能量采集器能够在10 cm距离驱动一个直径30 cm的壁钟，并在122 cm距离驱动一个湿度计。
