整流天线是无线电力传输的最重要组件之一。它已被开发用于许多应用，如空间太阳能发电系统（SSPS），和RFID等。由RF-DC转换电路和接收天线组成的整流天线需要设计为高转换效率，以实现高效的功率传输。本文提出了一种扩展的FDTD方法来计算RF-DC变换电路，并验证了该方法的有效性。此外，从电路的输出功率，包括辐射功率进行了研究。
A rectenna is one of the most important components for a wireless power transmission. It has been developed for many applications such as Space Solar Power System (SSPS), and RFID etc. The rectenna consisting of RF-DC conversion circuits and receiving antennas needs to be designed for high conversion efficiency to achieve efficient power transmission. In this paper, the extended FDTD method is proposed as a method for calculating the RF-DC conversion circuit, and the availability of this method is confirmed. Furthermore, the output power from the circuit including the radiation power is investigated.
