    • An apparatus and method for mounting a sensor having an antenna inside a wheel cavity is disclosed. The apparatus includes a body having a holder for holding the sensor. The apparatus also includes a passive antenna circuit electrically isolated from the antenna of the sensor. The passive antenna circuit includes a receiving antenna adjacent a first end of the holder, for receiving radio frequency energy radiated by the antenna of the sensor. The passive antenna circuit also includes a conductor electrically connected to the receiving antenna and extending inside the holder. The passive antenna circuit further includes a mount on a second end of the holder, opposite the first end, the mount being electrically connected to the conductor and operably configured to mechanically connect the conductor to an interior extending portion of an electrically conductive valve stem of the wheel and to electrically connect the conductor to the interior extending portion such that an exterior extending portion of the valve stem radiates at least some radio frequency energy coupled into the receiving antenna from the antenna of the sensor.
    • 公开了一种用于将具有天线的传感器安装在轮腔内的装置和方法。 该设备包括具有用于保持传感器的保持器的主体。 该设备还包括与传感器的天线电隔离的无源天线电路。 无源天线电路包括邻近保持器的第一端的接收天线,用于接收由传感器的天线辐射的射频能量。 无源天线电路还包括电连接到接收天线并在支架内延伸的导体。 所述无源天线电路进一步包括在所述保持器的与所述第一端相反的第二端上的安装件,所述安装件电连接到所述导体并且可操作地配置成将所述导体机械连接到所述导电阀杆的内延伸部分, 并且将导体电连接到内部延伸部分,使得阀杆的外部延伸部分辐射从传感器的天线耦合到接收天线中的至少一些射频能量。
