本文介绍了在850 MHz频率下使用高Q λ/4同轴介质谐振器和分布电容提高整流天线RF-DC转换效率的实验研究。为了达到最终的效率，我们已经构建了一个整流天线使用同轴介质谐振器和薄膜电容器。测试结果表明，在1 mW和0.1mW的低输入功率下，所研制的整流天线的RF-DC转换效率分别为76.2%和44.1%，与采用LC谐振器的整流天线相比，效率提高了20%。
This paper presents experimental studies on the improvement of RF-DC conversion efficiency of the rectenna using a high Q λ/4-coaxial dielectric resonator and distributed capacitors at 850MHz. In order to achieve an ultimate efficiency, we have constructed a rectenna using both a coaxial dielectric resonator and a film capacitor. The measured results show that the developed rectenna has an RF-DC conversion efficiency of 76.2% and 44.1% at a low input power of 1mWand 0.1mW that achieves the 20%efficiency improvement compared with the rectenna with an LC resonator.
