    • Exemplary embodiments are directed to public wireless-power-transmission. A device disposed in or on a publicly placed structure and a user neighboring device includes a repeater antenna with a loop antenna and a capacitive element. The public wireless-power-transmitting device includes a transmit antenna to wirelessly transfer power by generating a near-field radiation at a resonant frequency within a coupling- mode region and an amplifier for driving the transmit antenna. When in the coupling- mode region, the repeater antenna couples with the near-field radiation generated by the transmit antenna and develops an enhanced coupling-mode region about the repeater antenna with a repeated near-field radiation that is stronger than the near-field radiation of the transmit antenna within the enhanced coupling-mode region. Power may be wirelessly transferred from the enhanced coupling-mode region to a receiver device including a receive antenna.
    • 示例性实施例涉及公共无线电力传输。 设置在公共结构中或其上的设备和用户相邻设备包括具有环形天线和电容元件的中继器天线。 公共无线电力发送装置包括通过在耦合模式区域内产生谐振频率的近场辐射和用于驱动发射天线的放大器来无线地传输功率的发射天线。 当在耦合模式区域中,中继器天线与由发射天线产生的近场辐射耦合,并且利用比近场强的重复的近场辐射来形成关于中继器天线的增强的耦合模式区域 在增强的耦合模式区域内的发射天线的辐射。 功率可以从增强耦合模式区域无线地传送到包括接收天线的接收机设备。
