摘　　要：近些年,纺织天线作为可穿戴产品射频能量收集系统中的重要电子设备,越来越受到青睐。为研究基于纺织天线的射频能量收集系统的收集性能,该研究设计并制备了以涤纶毡为基底的纺织微带单元天线和纺织微带阵列天线。为了建立一个完整的射频能量收集系统,将信号发生器、功率放大器、发射天线和所设计的纺织微带天线(作为接收天线)与整流电路连接。研究结果表明,阵列天线的最大增益比单元天线高5.35 dB。最终的输出电压显示了射频能量收集系统的有效性。随着输入功率的增加、接收距离的减小,输出电压增加。通过单元天线的最高输出电压为39.2 mV,通过阵列天线的最高输出电压为72.7 mV,这是由于阵列天线的增益较高。这项研究将为该领域带来更多的研究思路。Textile antennas,critical electronic devices in radio frequency(RF)energy harvesting systems for wearable products,are increasingly preferable in recent years.In order to investigate the collection performance of RF energy harvesting system based on textile antennas,in this study,the textile microstrip single-element antenna and the textile microstrip array antenna were designed and prepared with polyester felts as the substrate.To build up a complete RF energy harvesting system,the combination of the signal generator,the power amplifier,the transmitting antenna and the above-designed textile microstrip antenna as the receiving antenna connected with the rectifier circuit was made.The results show that the maximum gain of the array antenna is 5.35 dB higher than that of the single-element antenna.The final output voltage shows the effectiveness of the RF energy harvesting system.As the input power increases or the receiving distance decreases,the output voltage increases.The highest output voltage through the single-element antenna is 39.2 mV,and the highest output voltage through the array antenna is 72.7 mV due to the higher gain of the array antenna.This study will bring more research ideas to this field.
