    • Aspects of return coupled wireless power transmission systems are described. In one embodiment, a system includes a guided surface waveguide probe including a charge terminal elevated at a height over a lossy conducting medium, a ground stake, and a feed network. The system further includes a conductor coupled to the ground stake that extends a distance away from the guided surface waveguide probe across the lossy conducting medium, and at least one guided surface wave receivers including a ground connection coupled to the conductor. The conductor can help to provide additional efficiency in power transfer between the guided surface waveguide probe and the guided surface wave receivers, especially when the operating frequency of the probe is in the medium, high, or very high frequency ranges.
    • 描述了返回耦合无线电力传输系统的方面。 在一个实施例中,系统包括引导表面波导探针,其包括在有损导电介质,接地桩和馈电网络上的高度上升高的充电端子。 该系统还包括耦合到接地桩的导体,其跨过有损耗的导电介质延伸一定距离导向表面波导探针,以及至少一个被引导的表面波接收器,包括耦合到导体的接地连接。 导体可以有助于在导向表面波导探针和引导表面波接收器之间的功率传递中提供额外的效率,特别是当探头的工作频率处于中等,高或非常高的频率范围时。
