在本文中，我们考虑了利用商用微波炉泄漏的微波场收集的电力的可能性。我们的实验结果表明，偶极天线在门前5厘米处接收到的泄漏约为0dBm(1 MW)。由偶极子天线和电荷泵组成的整流天线可以将泄漏的微波能量转换为直流电流。当微波炉工作2min时，可获得9.98mJ的能量。我们演示了这些能量足以驱动一个数字烹饪定时器倒计时3分钟，发出哔哔声2.5秒S。我们还演示了其他厨房设备的操作。
In this paper, we considered the possibility of using electricity harvested from the microwave field leaked from commercial microwave ovens. Our experimental results showed that the leakage received by a dipole antenna was about 0 dBm (1 mW) at a point 5 cm in front of the door. A rectenna consisting of a dipole antenna and charge pump can convert the leaked microwave energy into a DC current. When a microwave oven is operated for 2 min, 9.98 mJ of energy was harvested. We demonstrated that this energy is sufficient for powering a digital cooking timer to count down for 3 min and beep for 2.5 s. The operation of other kitchen devices was also demonstrated.
