    • A system for remotely controlling an electrical switching device is disclosed. The system includes a mounting fixture configured to be mounted in a wall. An electrical switching device is supported by the mounting fixture. The system also includes a cover configured to cover at least a portion of the mounting fixture. The system further includes a shielding plate configured to have a high electrical conductivity. The shielding plate is mounted proximate to the mounting fixture between the cover and the electrical switching device. The system also includes a directional, non-isotropic radio frequency (RF) antenna sized to fit within the cover and configured to transmit RF frequency signals. The RF antenna is located between the shielding plate and the cover at a predetermined distance from the shielding plate. The predetermined distance is selected to increase the capability of the RF antenna to send and receive the RF signals.
    • 公开了一种远程控制电气开关装置的系统。 该系统包括被配置为安装在墙壁中的安装夹具。 电气开关装置由安装夹具支撑。 该系统还包括构造成覆盖安装夹具的至少一部分的盖。 该系统还包括被配置为具有高导电性的屏蔽板。 屏蔽板靠近安装夹具安装在盖和电气开关装置之间。 该系统还包括一个定向的,非各向同性的射频(RF)天线,其尺寸设置成适合盖子并配置成传送RF频率信号。 RF天线位于屏蔽板和盖之间,距屏蔽板一定距离处。 选择预定距离以增加RF天线发送和接收RF信号的能力。
