本文介绍了一种用于能量采集的整流天线--整流天线的设计。该系统采用圆极化多频段微带天线来收集来自CDMA和GSM频段基站的电磁能量，并使用肖特基二极管将其转换为直流功率。对样机天线和整流结构的实验结果与仿真结果进行了验证。该整流天线系统在GSM 900频段的转换效率为23%。
This paper presents the design of a rectifying antenna i.e. rectenna for energy harvesting application. A circularly polarized multiband microstrip antenna is used to collect the electromagnetic energy radiated from cell towers in the CDMA and GSM bands and schottky diodes are used to convert it into DC power. The experimental results for prototype antenna and rectifier structures are verified with the simulated results. The conversion efficiency of the rectenna system is evaluated as 23% at GSM 900 frequency band.
