本文提出了一种紧凑型双波段整流天线GSM 900和GSM 1800的能量收集。该天线由一个较长的弯曲科赫分形元件的GSM 900频段和GSM 1800的辐射元件较短。该整流器由一个多段双频匹配网络、两个整流支路和滤波网络组成。在0.88 GHz和1.85 GHz下，分别测得峰值效率为62%和50%（分别为15.9 μW/cm ~ 2和19.1 μW/cm ~ 2）。当天线距离蜂窝基站25 m时，测量结果表明，所收集的功率能够为无电池的LCD手表供电，并实现1.275 V的输出电压。所提出的整流天线结构紧凑、效率高、成本低、易于制造，适用于射频能量收集和各种无线通信场景。
This paper presents a compact dual-band rectenna for GSM900 and GSM1800 energy harvesting. The monopole antenna consists of a longer bent Koch fractal element for GSM900 band and a shorter radiation element for GSM1800. The rectifier is composed of a multisection dual-band matching network, two rectifying branches, and filter networks. Measured peak efficiency of the proposed rectenna is 62% at 0.88 GHz 15.9 μW/cm2 and 50% at 1.85 GHz 19.1 μW/cm2, respectively. When the rectenna is 25 m away from a cellular base station, measurement result shows that the harvested power is able to power a batteryless LCD watch and achieve 1.275 V output voltage. The proposed rectenna is compact, efficient, low cost, and easy to fabricate, and it is suitable for RF energy harvesting and various wireless communication scenarios.
