设计了一个约A4纸大小的8×8发射机，用于5.7 GHz微波功率传输，目标是在3 m距离内传输超过100 mW。所提出的基于瓦片的设计在CW中实现高达68.6 dBm的EIRP，同时保持功率和成本效益的阵列缩放。采用了三角形网格阵列，并对其进行了优化。这保证了整个目标角度的EIRP超过65.0 dBm，以及完美的无光栅波瓣波束转向，以避免对现有无线通信和雷达系统造成不可接受的干扰。
An approximately A4 paper size, 8×8 transmitter is designed for 5.7 GHz microwave power transmission targeting over 100 mW delivery in 3 m distance. The proposed tile-based design achieves up to 68.6 dBm EIRP in CW while maintaining power and cost-effective array scaling. The triangular grid array is employed and optimized as well. This guarantees over 65.0 dBm EIRP for the entire target angle, as well as perfectly grating lobe-free beam steering to avoid unacceptable interference on the existing wireless communication and radar systems.
