摘要:
在微波无线能量传输系统中,整流天线广泛应用。为了解决整流天线中小型化的问题,对整流天线结构进行研究,提出一种新型整流天线设计。通过将天线和整流二极管阻抗直接共轭匹配进行设计,简化整流天线结构。该新型整流天线设计方法应用于2.45 GHz微带贴片微波整流天线中,用1 mm厚的F4B-2介质板设计和加工,设计出新型微带贴片整流天线,尺寸为70 mm×70 mm。实验结果显示,新型微带贴片整流天线最高整流效率为69.3%。新型整流天线相比传统整流天线具低剖面、轻重量、结构简化、低成本、容易加工和高射频-直流转换效率等优势,证明了该设计的有效性。
Abstract:
Rectennas are widely applied to wireless microwave power transmission systems. In order to realize the miniaturization of rectennas, the structures of rectennas were researched in this paper. This paper presented the design of a novel rectenna, in which the antenna impedance matches to the rectifying diode conjugation impedance directly. The impedances of antenna and rectifying diode were conjugate matched directly. The novel design method simplify the rectenna design. It is applied to a patch rectenna at 2.45 GHz. The novel patch rectenna was designed and fabricated on a 1 mm thick F4B-2 substrate with the physical dimension of 70 mm×70 mm. The highest measured MW-to-DC conversion efficiency at 2.45 GHz reached 69.3% in the experiment. The conclusion is that the novel rectenna has the advantages of low profile, light weight, structure simplification, low cost, and easy fabrication. Experiments prove the validity of the proposed design method.
