Abstract
We have designed and fabricated two different RF-DC Converters called doubler for 5.8GHz Microwave Wireless Power Transmission. The doubler as RF-DC Converter makes the rectified voltage be doubled. We measured and compared voltages of the doublers with those of the previous full-wave rectifying RF-DC Converter. The doublers show rectified double voltages. However, the full-wave rectifying converter has a high efficiency due to the suppression of reflecting harmonics. The other fabricated doublers causes so many harmonics that they can't convert the low-power RF to the full DC. In this paper, we show that the different doublers doesn't double the rectifying voltages compared with those of the full-wave rectifying converter and give a reason about that.
