在本文中，一个紧凑的，宽带，单层，简单的RF整流器设计的实施进行了讨论。建议的整流器配置是基于共面波导传输线。该整流器采用倍压电路和宽带匹配网络构成。为了获得小的电路尺寸，匹配电路由串联双电感集总元件构成。整流器的整体尺寸非常紧凑，为22.5\times 31\，\\text {mm}^{2}$。为了准确表征整流器的性能，使用Agilent，ADS软件进行电磁和谐波平衡仿真。比较表明，模拟和测量结果之间的良好协议。例如，在10 dBm RF输入功率下，峰值测量效率为74.8%，对应的仿真值为75%，终端负载为1 $\text{k}\Omega $。有效的频率范围是从0.1到2.5 GHz的扩展，与输入功率为10 dBm的效率超过45%。
In this paper, the implementation of a compact, wideband, single layer, and simple RF rectifier design is discussed. The proposed rectifier configuration is based on the coplanar waveguide transmission line. The rectifier is constructed using the voltage doubler circuit in conjunction with a broadband matching network. To obtain a small circuit size, the matching circuit is constituted with a series dual-inductive lumped element. The overall rectifier dimensions are very compact $22.5\times 31\,\,\text {mm}^{2}$ . In order to accurately characterize the rectifier performance, the electromagnetic and harmonic balance simulations are conducted using the Agilent, ADS software. The comparison shows good agreement between the simulation and measurement results. For instance, the peak measured efficiency is 74.8% at 10-dBm RF input power and the corresponding simulated value is 75% with a terminal load of 1 $\text{k}\Omega $ . The efficient frequency range is extending from 0.1 to 2.5 GHz, with an efficiency of more than 45% at input power 10 dBm.
