摘　　要：基于矩量法技术对微波二极管检波器的检波特性进行了分析.通过计算机仿真,研究了高频波纹及工作频率对微波二极管检波特性的影响.并将这一分析方法拓展到对倍压整流检波电路的分析,该方法已应用于设计微波电子标签的检波电路.在同等接收功率的条件下,倍压整流检波电路得到了更高的输出电压,提高了微波射频识别系统的灵敏度,取得了良好的预期效果.Based upon the method of moments, the detection behavior of a microwave diode detector is analyzed. By means of computer simulations, the influence of frequency and highfrequency echo on the detector behavior is studied. In addition, the doubler detector is also described by applying the above method. The voltage doubler provides a higher output voltage than the single diode at a given power level. The voltage doubler is already applied to the system of Radio Frequency Identification and a good performance has been achieved.
