在2.45 GHz和5.8 GHz （ISM频段）研制了一种用于无线电力传输的双频印刷偶极子整流天线。为了在双频下工作，研制了一种新型双频单平面印刷偶极子天线和一种新型共面带状线滤波器。采用器件非线性分析的方法选择低结电容的二极管，以减小频率依赖性的影响。在自由空间实现的测量转换效率为84.4和。分别为2.45 GHz和5.8 GHz。实测结果与理论分析吻合较好。
A dual frequency printed dipole rectenna has been developed at 2.45 and 5.8 GHz: (ISM bands) for the wireless power transmission. For operating at dual band, a new dual frequency uniplanar printed dipole antenna and a novel coplanar stripline (CPS) filter are developed. A device nonlinear analysis is used to select the diode with low junction capacitance to reduce the effect of frequency dependence. The measured conversion efficiencies achieved at free space are 84.4 and. 82.7% at 2.45 and 5.8 GHz, respectively. The measured results agree very well with the theoretical analysis.
