Abstract

We present a space solar power system using transmitarrays for lowering the system's LCOE (Levelized Cost of Energy). We discuss the theoretical framework for transmitarrays in the context of wireless power transfer, including the transmission phase limit associated with layered frequency selective surfaces. We then present a proposal for using transmitarrays to lower the LCOE of space solar powered systems that are limited by the transmitting aperture size. Finally, we design and fabricate a low-cost, lightweight static transmitarray prototype and demonstrate a $\sim$ 2.4x increase in power transferred from the phased array transmitter to the rectenna receiver.
用于地球和太空无线电力传输的发射阵列
我们介绍了一种利用发射天线阵降低系统 LCOE(平准化能源成本)的空间太阳能发电系统。我们讨论了无线电力传输背景下的发射天线阵理论框架,包括与分层频率选择表面相关的传输相位限制。然后,我们提出了利用发射天线阵降低受发射孔径大小限制的空间太阳能供电系统的 LCOE 的建议。最后,我们设计并制造了一个低成本、轻便的静态发射天线阵原型,并演示了从相控阵发射器传输到整流天线接收器的功率增加了 2.4 倍。
