Abstract

A novel high-efficiency microwave rectifier (MR) employing a parallel-connected single-stage voltage doubler (VD) to extend the operating bandwidth is proposed, which primarily consists of a coupled transmission line (CTL) and two parallel single-stage VD branches. The characteristics of the two parallel single-stage voltage doublers were analyzed theoretically and validated through simulation, demonstrating that the input impedance is insensitive to frequency variations by incorporating two inductors and a short tuning line. Making full use of this feature, a compact prototype with a simple matching network had been carefully designed, fabricated and measured. The experimental results show that the power conversion efficiency (PCE) is larger than 50% from 0.05 to 3.1 GHz, achieving a relative bandwidth of 193.6% at an input power of 10 dBm, in good agreement with simulation results. Additionally, the printed circuit board (PCB) size of the proposed rectifier can be as small as 21 × 11 mm^2.

一种小型宽带高效无线能量采集整流器的设计

提出了一种利用并联的单级倍压器（VD）扩展工作带宽的新型高效微波整流器（MR），它主要由一条耦合传输线（CTL）和两个并联的单级倍压器支路组成。对并联的两个单级倍压器的特性进行了理论分析和仿真验证，结果表明，通过引入两个电感和一条短调谐线，输入阻抗对频率变化不敏感。充分利用这一特点，精心设计、制作和测量了具有简单匹配网络的紧凑样机。实验结果表明，在0.05 ~ 3.1 GHz范围内，功率转换效率（PCE）大于50%，在输入功率为10 dBm时实现了193.6%的相对带宽，与仿真结果吻合较好。此外，所提出的整流器的印刷电路板（PCB）尺寸可以小到21 × 11 mm2。
